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 […]

Ragon Associate director Facundo Batista, PhD, has accepted an appointment as Chief Editor of The EMBO Journal. Batista, who is also a professor at Harvard Medical School, succeeds Bernd Pulverer, PhD, Head of Scientific Publishing at EMBO. “I am delighted to serve the wider scientific community by joining The EMBO Journal as Chief Editor,” says Batista. “It is […]

by: Rachel Leeson One of the most common metaphors used in science is the explanation of DNA as like an alphabet, with the bases of DNA like letters. Ragon Member Bryan Bryson, PhD, along with MIT professor Bonnie Berger, took this metaphor to a whole new level, using natural language processing to predict mutations […]

image courtesy of the authors Ragon scientists discover dendritic cells help regulate IL-6, a key component in cytokine storms. 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 […]

Ragon Institute scientists develop a one-step CRISPR technique to rapidly create mice capable of producing human antibodies To develop vaccines and investigate human immune responses, scientists rely on a variety of animal models, including mice that can produce human antibodies through genetically engineered B cell receptors, which are specialized antibodies bound to the B cell […]

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 […]
