LA JOLLA, CA Even before the COVID-19 pandemic, most people in the United States already had been sick with a coronavirus, albeit a far less dangerous one. That s because at least four coronaviruses in the same general family as SARS-CoV-2 cause the benign yet annoying illness known as the common cold.
In a new study that appears in
Nature Communications, scientists from Scripps Research investigated how the immune system s previous exposure to cold-causing coronaviruses impact immune response to COVID-19. In doing so, they discovered one cross-reactive coronavirus antibody that s triggered during a COVID-19 infection.
The findings will help in the pursuit of a vaccine or antibody treatment that works against most or all coronaviruses, says senior author Raiees Andrabi, PhD, an investigator in the Department of Immunology and Microbiology.

SAN FRANCISCO, May 11, 2021 /PRNewswire/ In the decade since the advent of CRISPR-Cas9 gene editing, researchers have used the technology to delete or change genes in a growing number of cell types. Now, researchers at Gladstone Institutes and UC San Francisco (UCSF) have added human monocytes white blood cells that play key roles in the immune system to that list.
A team of scientists at Gladstone Institutes and UC San Francisco led by Alex Marson (left) and Nevan Krogan (right) fine-tuned CRISPR-Cas9 genome editing to help understand how the human immune system fights viruses and microbes.

SAN FRANCISCO, April 27, 2021 /PRNewswire/ In the 40-some years since the beginning of the HIV/AIDS epidemic, scientists have learned a lot about the virus, the disease, and ways to treat it. But one thing they still don t completely understand is which exact cells are most susceptible to HIV infection.
Without this knowledge, it is difficult to envision targeting these cells to protect the millions of people who encounter the virus for the first time every year, or the infected people in which infection will likely rebound if they go off therapy.
(HealthNewsDigest.com) - LA JOLLA, CALIF. – April 16, 2021 – Scientists at Sanford Burnham Prebys have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers’ understanding of factors that affect disease severity and also suggest possible therapeutic options. The genes in question are related to interferons, the body’s frontline virus fighters.
The study was published in the journal
“We wanted to gain a better understanding of the cellular response to SARS-CoV-2, including what drives a strong or weak response to infection,” says Sumit K. Chanda, Ph.D., professor and director of the Immunity and Pathogenesis Program at Sanford Burnham Prebys and lead author of the study. “We’ve gained new insights into how the virus exploits the human cells it invades, but we are still searching for its Achille’s heel so that we can develop optimal antivir
