Pregnant women show robust immune response to COVID vaccines, pass antibodies to newborns. In the largest study of its kind to date, researchers at Massachusetts General Hospital, Brigham and Women’s Hospital, and the Ragon Institute of Mass General, MIT, and Harvard have found the new mRNA COVID-?? vaccines to be highly effective in producing antibodies […]

ISSN 2002-4436 Ragon scientists discover epigenetic changes unique to B cells and B cell subtypes. Antibodies are a vital part of our immune system, but they don’t just appear when they’re needed. They […]

Single-cell analysis of autopsy samples from COVID-19 patients shows how the lungs repeatedly tried, and failed, to repair themselves. By Stephanie M. McPherson, Broad Institute Image credit: Domenic Abbondanza Image description: Researchers profiled lung tissue from deceased COVID-19 patients and zoomed in on key regions and structures of interest. A group of scientists from several […]

by: Rachel Leeson. Image courtesy of: iSO-FORM LLC Researchers at the Ragon Institute of Mass General, MIT, and Harvard and at Massachusetts General Hospital find that neutralizing antibodies raised by COVID-19 vaccines are not as effective at neutralizing some new, circulating SARS-CoV-2 variants. SARS-CoV-2, the virus that causes COVID-19, has mutated throughout the […]

by: Rachel Leeson. Image credit: MRI Scan, courtesy of the NIH. A stroke, like any traumatic event in the body, triggers an immune response and understanding this immune response is critical to improve patient outcomes and nominate new therapeutics. But immune responses in the brain are difficult to study in humans, because the brain is […]

by: Rachel Leeson; image credit: Illustration from Anatomy & Physiology, Connexions Web site Researchers at the Ragon Institute of Mass General, MIT, and Harvard and Massachusetts General Hospital show that levels of specific antibodies developed in the immune response may influence COVID-19 outcomes in both children and adults. COVID-19, the source of the current pandemic, may […]

by: Rachel Leeson. Image credit: antibody opsonization, Maher33 While PCR testing has been used widely for COVID-19 diagnosis, it only provides information on who is currently infected. Antibody testing can tell who has been previously exposed to SARS-CoV-2, the virus that causes COVID-19, a metric that is essential for tracking spread across a population. […]

Most HIV-infected cells can be readily killed by immune cells, which recognize and attack infected cells that are making copies of the virus. Ragon postdoc Kiera Clayton, however, found that HIV-infected […]
