The cytokine IL-6 is a major driver of immune response and, when present in high levels in the blood, can help drive cytokine storms, such as seen in severe COVID-19 disease. Recently, Ragon scientists […]

By Claudia Lopez Lloreda, Broad Institute The nervous and immune systems have long been thought to be separate entities in the body, but new research has uncovered a direct cellular interaction between the two. Scientists from Harvard Medical School, the Broad Institute of MIT and Harvard, MIT, and the Ragon Institute of Mass General, […]

Understanding the body’s immune response to SARS-CoV-2, the virus that causes COVID-19, is key to developing effective treatments and long-lasting vaccines. Of […]

Image Credit: Novel Coronavirus SARS-CoV-2, NIH COVID-19 vaccines are on the near horizon, but many questions on COVID-19 immunity remain for researchers to answer as they work to combat the global pandemic. One major goal is to develop a detailed understanding of what a protective immune response to SARS-CoV-2, the virus that causes COVID-19, looks […]

The Ragon Institute’s ITEACH program is enlisting local leaders in South Africa’s rural communities to combat COVID-19 ITEACH (Integration of TB in Education and Care for HIV/AIDS), a Ragon Institute program in South Africa, is enlisting leadership within rural communities in the country’s KwaZulu-Natal province to counter a second wave of the COVID-19 pandemic. By delivering […]

Image: SARS-CoV-2 virus, courtesy of the NIH For COVID-19, the difference between surviving and not surviving severe disease may be due to the quality, not the quantity, of the patients’ antibody development and response, a new Cell paper published by Ragon Member Galit Alter, PhD, suggests. The study, published in the journal Cell, used Alter’s […]

Ragon Institute researchers show elite controllers have HIV viral reservoirs in gene deserts which may help prevent viral rebound and contribute to natural control of HIV. Xu Yu, MD, Ragon Group Leader, recently published a study entitled “Distinct viral reservoirs in individuals with spontaneous control of HIV-1,” in the journal Nature. Yu’s lab, in collaboration […]

Results of partnership between the Ragon Institute of Mass General, MIT, and Harvard and UW Medicine identify five markers of the humoral immune response that may be able to predict COVID-19 patient outcomes. A recent study published in Immunity identifies five immune response markers which, collectively, were able to correctly classify both convalescent COVID-19 […]

Bronwyn Gunn, Wen-Han Yu, and Galit Alter From 2013–2016, West Africa faced the deadliest Ebola outbreak the world has ever seen. By the time the outbreak was declared over, 11,325 people had died. Antibody therapy is considered among the most promising treatments for the Ebola virus infection, and the hope is that the most effective […]
