Shalek and Jose Ordovas-Montanes were broadly studying single cell responses to inflammation, cancer, and various infections. Then COVID-19 arrived.&nbsp;</span></p> <p> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Institute member Shalek and associate member Ordovas-Montanes of the </span><a href="/klarman-cell-observatory" target="_blank">Klarman Cell Observatory</a> at the ӳ����ý of MIT and Harvard quickly pivoted their research.&nbsp;</p> <p> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Now, they are using their single-cell tools to learn which </span><a href="/node/628256" target="_blank">cell types SARS-CoV-2 attacks</a>, characterize different therapeutic and prevention strategies, and uncover what causes protective responses in some patients and not others. The researchers have also been part of a significant change in the way science is being done.</p> <p> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek is also the Pfizer-Laubach Career Development Associate Professor of Chemistry, a core member of the Institute for Medical Engineering and Science, and an extramural member of the Koch Institute for Integrative Cancer Research at MIT, as well as an associate member of the Ragon Institute. Ordovas-Montanes is a principal investigator at Boston Children’s Hospital, assistant professor at Harvard Medical School, and a former postdoctoral researcher in the Shalek lab.</span></p> <p> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">They recently sat down with us over a Zoom call in a COVID-19 edition of a #WhyIScience Q&amp;A to talk about a new study on COVID-19 disease in children, which is being done in collaboration with clinicians at Boston Children’s Hospital and scientists at the ӳ����ý as part of the </span><a href="https://www.humancellatlas.org/" target="_blank">Human Cell Atlas</a> (HCA) initiative. They also talked about how their approach to research, and their field of single-cell genomics, have changed in the age of COVID.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What got you interested in studying pediatric patients’ responses to SARS-CoV-2?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>:</strong> From some of the preliminary COVID-19 clinical observations, it was evident that kids, in general, are handling this viral infection better than adults, and there was something significant that we could learn from them. We figured we might have this ability to assemble a unique cohort, not to look at the most severe outcomes of disease, but rather to look into what seems to be working better in kids that allows them to generally avoid severe disease.</p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> We wanted an opportunity to study the cells that are infected and cells that are bystanders of the infection in children, and to understand how both are changing within the same tissue sample. This would enable us to uncover differences relative to other cohorts that have been shown to experience, on average, more severe disease. That is one of the most powerful aspects of single-cell RNA sequencing (scRNA-seq), whereas, in bulk RNA-sequencing, we would have lost the ability to resolve this information.</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. Can you tell me a bit more about the study?&nbsp;</span></strong></p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Ordovas-Montanes:</strong> </span>We plan to enroll children presenting symptoms consistent with a respiratory viral infection to the Emergency Department (ED) at Boston Children’s Hospital. Given current patterns, we anticipate identifying at least 20 SARS-CoV-2 positive patients and 20 patients with other RNA viral infections. We will also enroll a control group of 20 asymptomatic patients visiting the ED for minor injuries that aren’t related to COVID-19. We will be collecting nasopharyngeal swabs, the type used for viral testing, a sampling strategy that also lets us collect a considerable number of host cells off these swabs.</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Shalek:</strong> </span>Our research team at the ӳ����ý will then process the nasal scraping samples for scRNA-seq to identify constituent cell types, both infected and bystander. Using this data, we will identify specific genes and pathways associated with infection and, by comparing to other cohorts, factors associated with disease severity.&nbsp;</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">We will be maintaining as much precaution as possible for the investigators handling any of these samples. We will be following physical distancing guidelines and have a tightly integrated pipeline to minimize risks to everyone that's involved in the experimental side of the study.</span></p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. How are you doing this study differently, given the pandemic?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>Unlike the traditional academic publishing process, given the pandemic, our overall mission for this study has shifted to prioritizing data release above deliverables such as pre-prints or publications. Even though we will be generating valuable data, with measurements taken from both cases and controls, we believe to fully maximize its potential, it requires the interpretation of the international research community. They should&nbsp; be able to dive in and identify what's going on by comparing our datasets to multiple other datasets in cohorts of different ages.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>: </strong>The plan is to make all the data from this study publicly available via ӳ����ý’s <a href="https://singlecell.broadinstitute.org/single_cell" target="_blank">Single Cell Portal</a> as quickly as is possible. Collecting large datasets and making them rapidly accessible has been a priority for us. We want to support the community how we can, and empower as many people as is humanly possible –– to help accelerate our joint fight against COVID-19. Ultimately the data will also get added to the <a href="https://www.covid19cellatlas.org/" target="_blank">COVID-19 Cell Atlas</a>, a comprehensive resource for exploring the cell-type-specific expression of SARS-CoV-2-linked genes.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What other changes have you seen in how single-cell science is being done in this public health emergency?</span>&nbsp;</strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> I’ve been amazed by the way in which the global scientific community has pulled together to tackle the pandemic –– by the willingness to collaborate, to share unpublished data, and to support one another at all levels. It’s been truly inspiring to see everyone work together and incredible to see how much it’s enabled us to accomplish in a short time. I hope we can figure out a way to maintain this sense of community going forward.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>It hasn’t just been single-cell science that has changed, but rather many scientific efforts. We’ve had the opportunity to rapidly meet people both within our own institutions and around the world through collaborative groups at Boston Children’s Hospital, Massachusetts Consortium on Pathogen Readiness, the Chan Zuckerberg Initiative (which is funding the pediatric study), and even organically through Twitter. We hope to continue working with these colleagues on COVID-19 related efforts, and also on other fundamental questions in biology. One key element to keep in mind is to ensure that through these rapid changes, the practice of science keeps making progress towards a more equitable community.&nbsp;&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What inspires you the most about the pediatric study and the other COVID-19-related work you are doing during the pandemic?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> That we can play a part in helping the community at large. When the data from this study gets merged with other datasets that are being collected by other labs around the world, it will help paint a more holistic view of the impact of SARS-CoV-2 and hopefully suggest new therapeutic and prophylactic strategies.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>:</strong> I think we are excited to be a small part of a broader vision. It is inspiring to be associated with the HCA, which has responded quickly to the COVID-19 pandemic. They managed to bring together a community of researchers around the world. We are looking forward to working with other teams across the globe to understand what single-cell sampling will teach us about the impact of SARS-CoV-2 on each individual or group of patients.&nbsp;</p> </div> </div> <div class="block-node-broad-tags block block-layout-builder block-field-blocknodeblogfield-broad-tags"> <div class="block-node-broad-tags__row"> <div class="block-node-broad-tags__title">Tags:</div> <div class="field field--name-field-broad-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/broad-tags/hca" hreflang="en">HCA</a></div> <div class="field__item"><a href="/broad-tags/klarman-cell-observatory" hreflang="en">Klarman Cell Observatory</a></div> <div class="field__item"><a href="/broad-tags/coronavirus" hreflang="en">Coronavirus</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-international-collaboration" hreflang="en">Human Cell Atlas: International collaboration</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-reading-biology" hreflang="en">Human Cell Atlas: Reading biology</a></div> <div class="field__item"><a href="/broad-tags/single-cell-genomics" hreflang="en">Single cell genomics</a></div> <div class="field__item"><a href="/broad-tags/single-cell" hreflang="en">Single Cell</a></div> </div> </div> </div> </div> <div class="content-section__right col-2"> <div class="block block-ctools block-entity-viewnode"> <article about="/blog/whyiscience-qa-researchers-study-single-cells-ask-why-children-generally-fare-better-against-covid-19" class="node node--type-blog node--promoted node--view-mode-sidebar"> <div class="node__content"> <div class="sidebar-group"> <div class="sidebar-group__content"> <div class="block block-layout-builder block-field-blocknodeblogfield-blog-extra-info"> <div class="clearfix text-formatted field field--name-field-blog-extra-info field--type-text-long field--label-hidden field__item"><h2> Related People</h2> <p> <a href="/node/446101" target="_blank">Alex K.

The researchers have also been part of a significant change in the way science is being done.</p> <p> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek is also the Pfizer-Laubach Career Development Associate Professor of Chemistry, a core member of the Institute for Medical Engineering and Science, and an extramural member of the Koch Institute for Integrative Cancer Research at MIT, as well as an associate member of the Ragon Institute. Ordovas-Montanes is a principal investigator at Boston Children’s Hospital, assistant professor at Harvard Medical School, and a former postdoctoral researcher in the Shalek lab.</span></p> <p> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">They recently sat down with us over a Zoom call in a COVID-19 edition of a #WhyIScience Q&amp;A to talk about a new study on COVID-19 disease in children, which is being done in collaboration with clinicians at Boston Children’s Hospital and scientists at the ӳ����ý as part of the </span><a href="https://www.humancellatlas.org/" target="_blank">Human Cell Atlas</a> (HCA) initiative. They also talked about how their approach to research, and their field of single-cell genomics, have changed in the age of COVID.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What got you interested in studying pediatric patients’ responses to SARS-CoV-2?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>:</strong> From some of the preliminary COVID-19 clinical observations, it was evident that kids, in general, are handling this viral infection better than adults, and there was something significant that we could learn from them. We figured we might have this ability to assemble a unique cohort, not to look at the most severe outcomes of disease, but rather to look into what seems to be working better in kids that allows them to generally avoid severe disease.</p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> We wanted an opportunity to study the cells that are infected and cells that are bystanders of the infection in children, and to understand how both are changing within the same tissue sample. This would enable us to uncover differences relative to other cohorts that have been shown to experience, on average, more severe disease. That is one of the most powerful aspects of single-cell RNA sequencing (scRNA-seq), whereas, in bulk RNA-sequencing, we would have lost the ability to resolve this information.</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. Can you tell me a bit more about the study?&nbsp;</span></strong></p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Ordovas-Montanes:</strong> </span>We plan to enroll children presenting symptoms consistent with a respiratory viral infection to the Emergency Department (ED) at Boston Children’s Hospital. Given current patterns, we anticipate identifying at least 20 SARS-CoV-2 positive patients and 20 patients with other RNA viral infections. We will also enroll a control group of 20 asymptomatic patients visiting the ED for minor injuries that aren’t related to COVID-19. We will be collecting nasopharyngeal swabs, the type used for viral testing, a sampling strategy that also lets us collect a considerable number of host cells off these swabs.</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Shalek:</strong> </span>Our research team at the ӳ����ý will then process the nasal scraping samples for scRNA-seq to identify constituent cell types, both infected and bystander. Using this data, we will identify specific genes and pathways associated with infection and, by comparing to other cohorts, factors associated with disease severity.&nbsp;</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">We will be maintaining as much precaution as possible for the investigators handling any of these samples. We will be following physical distancing guidelines and have a tightly integrated pipeline to minimize risks to everyone that's involved in the experimental side of the study.</span></p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. How are you doing this study differently, given the pandemic?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>Unlike the traditional academic publishing process, given the pandemic, our overall mission for this study has shifted to prioritizing data release above deliverables such as pre-prints or publications. Even though we will be generating valuable data, with measurements taken from both cases and controls, we believe to fully maximize its potential, it requires the interpretation of the international research community. They should&nbsp; be able to dive in and identify what's going on by comparing our datasets to multiple other datasets in cohorts of different ages.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>: </strong>The plan is to make all the data from this study publicly available via ӳ����ý’s <a href="https://singlecell.broadinstitute.org/single_cell" target="_blank">Single Cell Portal</a> as quickly as is possible. Collecting large datasets and making them rapidly accessible has been a priority for us. We want to support the community how we can, and empower as many people as is humanly possible –– to help accelerate our joint fight against COVID-19. Ultimately the data will also get added to the <a href="https://www.covid19cellatlas.org/" target="_blank">COVID-19 Cell Atlas</a>, a comprehensive resource for exploring the cell-type-specific expression of SARS-CoV-2-linked genes.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What other changes have you seen in how single-cell science is being done in this public health emergency?</span>&nbsp;</strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> I’ve been amazed by the way in which the global scientific community has pulled together to tackle the pandemic –– by the willingness to collaborate, to share unpublished data, and to support one another at all levels. It’s been truly inspiring to see everyone work together and incredible to see how much it’s enabled us to accomplish in a short time. I hope we can figure out a way to maintain this sense of community going forward.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>It hasn’t just been single-cell science that has changed, but rather many scientific efforts. We’ve had the opportunity to rapidly meet people both within our own institutions and around the world through collaborative groups at Boston Children’s Hospital, Massachusetts Consortium on Pathogen Readiness, the Chan Zuckerberg Initiative (which is funding the pediatric study), and even organically through Twitter. We hope to continue working with these colleagues on COVID-19 related efforts, and also on other fundamental questions in biology. One key element to keep in mind is to ensure that through these rapid changes, the practice of science keeps making progress towards a more equitable community.&nbsp;&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What inspires you the most about the pediatric study and the other COVID-19-related work you are doing during the pandemic?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> That we can play a part in helping the community at large. When the data from this study gets merged with other datasets that are being collected by other labs around the world, it will help paint a more holistic view of the impact of SARS-CoV-2 and hopefully suggest new therapeutic and prophylactic strategies.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>:</strong> I think we are excited to be a small part of a broader vision. It is inspiring to be associated with the HCA, which has responded quickly to the COVID-19 pandemic. They managed to bring together a community of researchers around the world. We are looking forward to working with other teams across the globe to understand what single-cell sampling will teach us about the impact of SARS-CoV-2 on each individual or group of patients.&nbsp;</p> </div> </div> <div class="block-node-broad-tags block block-layout-builder block-field-blocknodeblogfield-broad-tags"> <div class="block-node-broad-tags__row"> <div class="block-node-broad-tags__title">Tags:</div> <div class="field field--name-field-broad-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/broad-tags/hca" hreflang="en">HCA</a></div> <div class="field__item"><a href="/broad-tags/klarman-cell-observatory" hreflang="en">Klarman Cell Observatory</a></div> <div class="field__item"><a href="/broad-tags/coronavirus" hreflang="en">Coronavirus</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-international-collaboration" hreflang="en">Human Cell Atlas: International collaboration</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-reading-biology" hreflang="en">Human Cell Atlas: Reading biology</a></div> <div class="field__item"><a href="/broad-tags/single-cell-genomics" hreflang="en">Single cell genomics</a></div> <div class="field__item"><a href="/broad-tags/single-cell" hreflang="en">Single Cell</a></div> </div> </div> </div> </div> <div class="content-section__right col-2"> <div class="block block-ctools block-entity-viewnode"> <article about="/blog/whyiscience-qa-researchers-study-single-cells-ask-why-children-generally-fare-better-against-covid-19" class="node node--type-blog node--promoted node--view-mode-sidebar"> <div class="node__content"> <div class="sidebar-group"> <div class="sidebar-group__content"> <div class="block block-layout-builder block-field-blocknodeblogfield-blog-extra-info"> <div class="clearfix text-formatted field field--name-field-blog-extra-info field--type-text-long field--label-hidden field__item"><h2> Related People</h2> <p> <a href="/node/446101" target="_blank">Alex K.

We figured we might have this ability to assemble a unique cohort, not to look at the most severe outcomes of disease, but rather to look into what seems to be working better in kids that allows them to generally avoid severe disease.</p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> We wanted an opportunity to study the cells that are infected and cells that are bystanders of the infection in children, and to understand how both are changing within the same tissue sample. This would enable us to uncover differences relative to other cohorts that have been shown to experience, on average, more severe disease.

Given current patterns, we anticipate identifying at least 20 SARS-CoV-2 positive patients and 20 patients with other RNA viral infections. We will also enroll a control group of 20 asymptomatic patients visiting the ED for minor injuries that aren’t related to COVID-19. We will be collecting nasopharyngeal swabs, the type used for viral testing, a sampling strategy that also lets us collect a considerable number of host cells off these swabs.</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Shalek:</strong> </span>Our research team at the ӳ����ý will then process the nasal scraping samples for scRNA-seq to identify constituent cell types, both infected and bystander. Using this data, we will identify specific genes and pathways associated with infection and, by comparing to other cohorts, factors associated with disease severity.&nbsp;</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">We will be maintaining as much precaution as possible for the investigators handling any of these samples.

Even though we will be generating valuable data, with measurements taken from both cases and controls, we believe to fully maximize its potential, it requires the interpretation of the international research community. They should&nbsp; be able to dive in and identify what's going on by comparing our datasets to multiple other datasets in cohorts of different ages.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>: </strong>The plan is to make all the data from this study publicly available via ӳ����ý’s <a href="https://singlecell.broadinstitute.org/single_cell" target="_blank">Single Cell Portal</a> as quickly as is possible. Collecting large datasets and making them rapidly accessible has been a priority for us. We want to support the community how we can, and empower as many people as is humanly possible –– to help accelerate our joint fight against COVID-19. Ultimately the data will also get added to the <a href="https://www.covid19cellatlas.org/" target="_blank">COVID-19 Cell Atlas</a>, a comprehensive resource for exploring the cell-type-specific expression of SARS-CoV-2-linked genes.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What other changes have you seen in how single-cell science is being done in this public health emergency?</span>&nbsp;</strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> I’ve been amazed by the way in which the global scientific community has pulled together to tackle the pandemic –– by the willingness to collaborate, to share unpublished data, and to support one another at all levels. It’s been truly inspiring to see everyone work together and incredible to see how much it’s enabled us to accomplish in a short time. I hope we can figure out a way to maintain this sense of community going forward.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>It hasn’t just been single-cell science that has changed, but rather many scientific efforts. We’ve had the opportunity to rapidly meet people both within our own institutions and around the world through collaborative groups at Boston Children’s Hospital, Massachusetts Consortium on Pathogen Readiness, the Chan Zuckerberg Initiative (which is funding the pediatric study), and even organically through Twitter. We hope to continue working with these colleagues on COVID-19 related efforts, and also on other fundamental questions in biology. One key element to keep in mind is to ensure that through these rapid changes, the practice of science keeps making progress towards a more equitable community.&nbsp;&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q.

When the data from this study gets merged with other datasets that are being collected by other labs around the world, it will help paint a more holistic view of the impact of SARS-CoV-2 and hopefully suggest new therapeutic and prophylactic strategies.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>:</strong> I think we are excited to be a small part of a broader vision. It is inspiring to be associated with the HCA, which has responded quickly to the COVID-19 pandemic. They managed to bring together a community of researchers around the world. We are looking forward to working with other teams across the globe to understand what single-cell sampling will teach us about the impact of SARS-CoV-2 on each individual or group of patients.&nbsp;</p> </div> </div> <div class="block-node-broad-tags block block-layout-builder block-field-blocknodeblogfield-broad-tags"> <div class="block-node-broad-tags__row"> <div class="block-node-broad-tags__title">Tags:</div> <div class="field field--name-field-broad-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/broad-tags/hca" hreflang="en">HCA</a></div> <div class="field__item"><a href="/broad-tags/klarman-cell-observatory" hreflang="en">Klarman Cell Observatory</a></div> <div class="field__item"><a href="/broad-tags/coronavirus" hreflang="en">Coronavirus</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-international-collaboration" hreflang="en">Human Cell Atlas: International collaboration</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-reading-biology" hreflang="en">Human Cell Atlas: Reading biology</a></div> <div class="field__item"><a href="/broad-tags/single-cell-genomics" hreflang="en">Single cell genomics</a></div> <div class="field__item"><a href="/broad-tags/single-cell" hreflang="en">Single Cell</a></div> </div> </div> </div> </div> <div class="content-section__right col-2"> <div class="block block-ctools block-entity-viewnode"> <article about="/blog/whyiscience-qa-researchers-study-single-cells-ask-why-children-generally-fare-better-against-covid-19" class="node node--type-blog node--promoted node--view-mode-sidebar"> <div class="node__content"> <div class="sidebar-group"> <div class="sidebar-group__content"> <div class="block block-layout-builder block-field-blocknodeblogfield-blog-extra-info"> <div class="clearfix text-formatted field field--name-field-blog-extra-info field--type-text-long field--label-hidden field__item"><h2> Related People</h2> <p> <a href="/node/446101" target="_blank">Alex K.

We figured we might have this ability to assemble a unique cohort, not to look at the most severe outcomes of disease, but rather to look into what seems to be working better in kids that allows them to generally avoid severe disease.</p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> We wanted an opportunity to study the cells that are infected and cells that are bystanders of the infection in children, and to understand how both are changing within the same tissue sample. This would enable us to uncover differences relative to other cohorts that have been shown to experience, on average, more severe disease.

We figured we might have this ability to assemble a unique cohort, not to look at the most severe outcomes of disease, but rather to look into what seems to be working better in kids that allows them to generally avoid severe disease.</p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> We wanted an opportunity to study the cells that are infected and cells that are bystanders of the infection in children, and to understand how both are changing within the same tissue sample. This would enable us to uncover differences relative to other cohorts that have been shown to experience, on average, more severe disease. That is one of the most powerful aspects of single-cell RNA sequencing (scRNA-seq), whereas, in bulk RNA-sequencing, we would have lost the ability to resolve this information.</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q.

Given current patterns, we anticipate identifying at least 20 SARS-CoV-2 positive patients and 20 patients with other RNA viral infections. We will also enroll a control group of 20 asymptomatic patients visiting the ED for minor injuries that aren’t related to COVID-19. We will be collecting nasopharyngeal swabs, the type used for viral testing, a sampling strategy that also lets us collect a considerable number of host cells off these swabs.</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Shalek:</strong> </span>Our research team at the ӳ����ý will then process the nasal scraping samples for scRNA-seq to identify constituent cell types, both infected and bystander. Using this data, we will identify specific genes and pathways associated with infection and, by comparing to other cohorts, factors associated with disease severity.&nbsp;</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">We will be maintaining as much precaution as possible for the investigators handling any of these samples. We will be following physical distancing guidelines and have a tightly integrated pipeline to minimize risks to everyone that's involved in the experimental side of the study.</span></p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q.

Even though we will be generating valuable data, with measurements taken from both cases and controls, we believe to fully maximize its potential, it requires the interpretation of the international research community. They should&nbsp; be able to dive in and identify what's going on by comparing our datasets to multiple other datasets in cohorts of different ages.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>: </strong>The plan is to make all the data from this study publicly available via ӳ����ý’s <a href="https://singlecell.broadinstitute.org/single_cell" target="_blank">Single Cell Portal</a> as quickly as is possible. Collecting large datasets and making them rapidly accessible has been a priority for us. We want to support the community how we can, and empower as many people as is humanly possible –– to help accelerate our joint fight against COVID-19. Ultimately the data will also get added to the <a href="https://www.covid19cellatlas.org/" target="_blank">COVID-19 Cell Atlas</a>, a comprehensive resource for exploring the cell-type-specific expression of SARS-CoV-2-linked genes.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q.

It’s been truly inspiring to see everyone work together and incredible to see how much it’s enabled us to accomplish in a short time. I hope we can figure out a way to maintain this sense of community going forward.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>It hasn’t just been single-cell science that has changed, but rather many scientific efforts. We’ve had the opportunity to rapidly meet people both within our own institutions and around the world through collaborative groups at Boston Children’s Hospital, Massachusetts Consortium on Pathogen Readiness, the Chan Zuckerberg Initiative (which is funding the pediatric study), and even organically through Twitter. We hope to continue working with these colleagues on COVID-19 related efforts, and also on other fundamental questions in biology. One key element to keep in mind is to ensure that through these rapid changes, the practice of science keeps making progress towards a more equitable community.&nbsp;&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q.

They also talked about how their approach to research, and their field of single-cell genomics, have changed in the age of COVID.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What got you interested in studying pediatric patients’ responses to SARS-CoV-2?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>:</strong> From some of the preliminary COVID-19 clinical observations, it was evident that kids, in general, are handling this viral infection better than adults, and there was something significant that we could learn from them. We figured we might have this ability to assemble a unique cohort, not to look at the most severe outcomes of disease, but rather to look into what seems to be working better in kids that allows them to generally avoid severe disease.</p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> We wanted an opportunity to study the cells that are infected and cells that are bystanders of the infection in children, and to understand how both are changing within the same tissue sample. This would enable us to uncover differences relative to other cohorts that have been shown to experience, on average, more severe disease. That is one of the most powerful aspects of single-cell RNA sequencing (scRNA-seq), whereas, in bulk RNA-sequencing, we would have lost the ability to resolve this information.</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. Can you tell me a bit more about the study?&nbsp;</span></strong></p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Ordovas-Montanes:</strong> </span>We plan to enroll children presenting symptoms consistent with a respiratory viral infection to the Emergency Department (ED) at Boston Children’s Hospital. Given current patterns, we anticipate identifying at least 20 SARS-CoV-2 positive patients and 20 patients with other RNA viral infections. We will also enroll a control group of 20 asymptomatic patients visiting the ED for minor injuries that aren’t related to COVID-19. We will be collecting nasopharyngeal swabs, the type used for viral testing, a sampling strategy that also lets us collect a considerable number of host cells off these swabs.</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86"><strong>Shalek:</strong> </span>Our research team at the ӳ����ý will then process the nasal scraping samples for scRNA-seq to identify constituent cell types, both infected and bystander. Using this data, we will identify specific genes and pathways associated with infection and, by comparing to other cohorts, factors associated with disease severity.&nbsp;</p> <p dir="ltr"> <span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">We will be maintaining as much precaution as possible for the investigators handling any of these samples. We will be following physical distancing guidelines and have a tightly integrated pipeline to minimize risks to everyone that's involved in the experimental side of the study.</span></p> <p> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. How are you doing this study differently, given the pandemic?</span></strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>Unlike the traditional academic publishing process, given the pandemic, our overall mission for this study has shifted to prioritizing data release above deliverables such as pre-prints or publications. Even though we will be generating valuable data, with measurements taken from both cases and controls, we believe to fully maximize its potential, it requires the interpretation of the international research community. They should&nbsp; be able to dive in and identify what's going on by comparing our datasets to multiple other datasets in cohorts of different ages.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>: </strong>The plan is to make all the data from this study publicly available via ӳ����ý’s <a href="https://singlecell.broadinstitute.org/single_cell" target="_blank">Single Cell Portal</a> as quickly as is possible. Collecting large datasets and making them rapidly accessible has been a priority for us. We want to support the community how we can, and empower as many people as is humanly possible –– to help accelerate our joint fight against COVID-19. Ultimately the data will also get added to the <a href="https://www.covid19cellatlas.org/" target="_blank">COVID-19 Cell Atlas</a>, a comprehensive resource for exploring the cell-type-specific expression of SARS-CoV-2-linked genes.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q. What other changes have you seen in how single-cell science is being done in this public health emergency?</span>&nbsp;</strong></p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Shalek</span>:</strong> I’ve been amazed by the way in which the global scientific community has pulled together to tackle the pandemic –– by the willingness to collaborate, to share unpublished data, and to support one another at all levels. It’s been truly inspiring to see everyone work together and incredible to see how much it’s enabled us to accomplish in a short time. I hope we can figure out a way to maintain this sense of community going forward.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>: </strong>It hasn’t just been single-cell science that has changed, but rather many scientific efforts. We’ve had the opportunity to rapidly meet people both within our own institutions and around the world through collaborative groups at Boston Children’s Hospital, Massachusetts Consortium on Pathogen Readiness, the Chan Zuckerberg Initiative (which is funding the pediatric study), and even organically through Twitter. We hope to continue working with these colleagues on COVID-19 related efforts, and also on other fundamental questions in biology. One key element to keep in mind is to ensure that through these rapid changes, the practice of science keeps making progress towards a more equitable community.&nbsp;&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Q.

When the data from this study gets merged with other datasets that are being collected by other labs around the world, it will help paint a more holistic view of the impact of SARS-CoV-2 and hopefully suggest new therapeutic and prophylactic strategies.&nbsp;</p> <p dir="ltr"> <strong><span id="docs-internal-guid-1625e654-7fff-3c55-3548-2a4fc43b9a86">Ordovas-Montanes</span>:</strong> I think we are excited to be a small part of a broader vision. It is inspiring to be associated with the HCA, which has responded quickly to the COVID-19 pandemic. They managed to bring together a community of researchers around the world. We are looking forward to working with other teams across the globe to understand what single-cell sampling will teach us about the impact of SARS-CoV-2 on each individual or group of patients.&nbsp;</p> </div> </div> <div class="block-node-broad-tags block block-layout-builder block-field-blocknodeblogfield-broad-tags"> <div class="block-node-broad-tags__row"> <div class="block-node-broad-tags__title">Tags:</div> <div class="field field--name-field-broad-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/broad-tags/hca" hreflang="en">HCA</a></div> <div class="field__item"><a href="/broad-tags/klarman-cell-observatory" hreflang="en">Klarman Cell Observatory</a></div> <div class="field__item"><a href="/broad-tags/coronavirus" hreflang="en">Coronavirus</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-international-collaboration" hreflang="en">Human Cell Atlas: International collaboration</a></div> <div class="field__item"><a href="/broad-tags/human-cell-atlas-reading-biology" hreflang="en">Human Cell Atlas: Reading biology</a></div> <div class="field__item"><a href="/broad-tags/single-cell-genomics" hreflang="en">Single cell genomics</a></div> <div class="field__item"><a href="/broad-tags/single-cell" hreflang="en">Single Cell</a></div> </div> </div> </div> </div> <div class="content-section__right col-2"> <div class="block block-ctools block-entity-viewnode"> <article about="/blog/whyiscience-qa-researchers-study-single-cells-ask-why-children-generally-fare-better-against-covid-19" class="node node--type-blog node--promoted node--view-mode-sidebar"> <div class="node__content"> <div class="sidebar-group"> <div class="sidebar-group__content"> <div class="block block-layout-builder block-field-blocknodeblogfield-blog-extra-info"> <div class="clearfix text-formatted field field--name-field-blog-extra-info field--type-text-long field--label-hidden field__item"><h2> Related People</h2> <p> <a href="/node/446101" target="_blank">Alex K.
