Antibodies in blood soon after COVID onset may predict severity
“We’ve identified an early biomarker of risk for progression to severe symptoms. We found that antibodies elicited by an mRNA vaccine — in this case, Pfizer’s — differ in important, beneficial ways from those in people infected with SARS-CoV-2 who later progress to severe symptoms” said Taia Wang, assistant professor of infectious diseases and of microbiology and immunology.
Zooming in on naked RNA
A system developed by Stanford scientists M&I professor Wah Chiu and professor Rhiju Das gets 3D images of RNA-only molecules in high enough resolution to see structures that are key to understanding how they function. Guided by insights from their 3D structure of FSE, Das’s team and collaborators in M&I professor Jeff Glenn’s lab engineered DNA molecules that pair up with a strategic region of the FSE and disrupt its structure.

Jeffrey Glenn awarded grant to develop broad-spectrum antiviral drugs
Jeffrey Glenn, professor of gastroenterology and hepatology and of microbiology and immunology, has been awarded a five-year, $14.3 million contract from the National Institute of Allergy and Infectious Diseases to fund the development of broad-spectrum antiviral drugs for enteroviruses and potentially SARS-CoV-2.
Stanford Medicine researchers lead clinical trial of interferon-lambda for COVID-19
A clinical trial is underway to determine whether a drug can keep people who’ve just tested positive for the coronavirus out of the hospital, help them recover faster and make them safer to be around in the meantime. Co-leading the study are Principal investigators Prasanna Jagannathan, and Upinder Singh, both professors of infectious diseases and of microbiology and immunology.
Nine Stanford faculty elected to National Academy of Sciences
Peter Sarnow, professor of microbiology and immunology at Stanford is one of the faculty elected. He studies a microRNA specific to the liver. Sarnow hopes to gain insights that lead to new treatments for hepatitis C. His lab also studies interactions between viral messenger RNA and the protein-making machinery of cells these viruses infect.
What’s a virus, anyway? Part 2: How coronaviruses infect us — and how viruses created us
Here's more information about coronavirus with crucial assistance from Stanford virologist Jan Carette, associate professor of microbiology and immunology.
What’s a virus, anyway? Part 1: The bare-bones basics
As the coronavirus pandemic spreads across the globe, the term "virus" gets a lot of airplay. But what exactly are viruses, and how do they spread? Here's a primer, with a hat tip to Stanford virologist Jan Carette, associate professor of microbiology and immunology.
Stanford Medicine scientists have launched dozens of research projects as part of the global response to COVID-19. Some aim to prevent, diagnose and treat the disease; others aim to understand how it spreads and how people’s immune systems respond to it.
