Each month Levy Library showcases the achievements of Mount Sinai faculty and researchers by highlighting an article and its altmetrics. Altmetrics are alternative measures of impact that capture non-traditional data like abstract views, article downloads, and social media activity. Our altmetrics data is provided by the PlumX platform.
This month we highlight Imbalanced Host Response to SARS-CoV-2 Drives Development of COVID-19. This article was written in part by Daniel Blanco-Melo, Randy Albrecht, PhD, Jean K Lim, PhD, David Sachs, Benjamin Robert tenOever, PhD, David Sachs MS, and Benjamin Nilsson-Payant, PhD.
SARS-CoV-2 infection induces low IFN-I and -III levels with a moderate ISG response
Strong chemokine expression is consistent across in vitro, ex vivo, and in vivo models
Viral pandemics, such as the one caused by SARS-CoV-2, pose an imminent threat to humanity. Because of its recent emergence, there is a paucity of information regarding viral behavior and host response following SARS-CoV-2 infection. Here we offer an in-depth analysis of the transcriptional response to SARS-CoV-2 compared with other respiratory viruses. Cell and animal models of SARS-CoV-2 infection, in addition to transcriptional and serum profiling of COVID-19 patients, consistently revealed a unique and inappropriate inflammatory response. This response is defined by low levels of type I and III interferons juxtaposed to elevated chemokines and high expression of IL-6. We propose that reduced innate antiviral defenses coupled with exuberant inflammatory cytokine production are the defining and driving features of COVID-19.
