An Innately Trained Response Supports Elite Control of HIV

May 4, 2021

by: Rachel Leeson. Image credit: Christinelmiller, wikicommons   Ragon scientists discover elite controllers have myeloid dendritic cells that display characteristics of trained innate immune cells   Most discussions around immunity center around the adaptive immune response, the part of the immune system made up of antibodies and T cells that learn to fight specific pathogens […]

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 […]

Maternal Protection: COVID-19 vaccines induce robust immune response in pregnant individuals

Mar 25, 2021

by: Julie Cunningham, MGH. Image credit: Galit Alter/Cell   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 […]

Vaccine-induced antibodies may be less effective against several new SARS-CoV-2 variants

Mar 12, 2021

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 […]

Ragon Institute and Cambridge Public Library Host COVID-19 Seminar

Mar 10, 2021 Ragon Culture

image credit: Lisa Ferdinando, Office of the Secretary of Defense As part of its commitment to science education, the Ragon Institute had the unique opportunity of working with the Cambridge Public Library to bring COVID-19 information straight from researchers to the public. Ragon Director Bruce Walker, MD; Harvard postdoctoral fellow Zuri Sullivan, PhD; and Josefine […]

COVID-19 Primer for the Public

Feb 23, 2021 Ragon Culture

The Ragon Institute of Mass General, MIT, and Harvard is collaborating with the Cambridge Public Library on “Vaccines and the COVID-19 Pandemic: A Primer for the Public,” as part of the Cambridge Public Library’s Our Path Forward Series. The event, which features Bruce Walker, MD, Director of the Ragon, and Zuri Sullivan, PhD, will take […]

Behind Closed Doors: Insight into stroke recovery

Feb 22, 2021

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 […]

Antibody Response May Drive COVID-19 Outcomes

Feb 18, 2021

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 […]

New Insight into Antibody-Induced Protective Immunity to COVID-19

Feb 15, 2021

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. […]

Natural Resistance: HIV-Infected Macrophages Resist Killer Immune Cells

Feb 10, 2021

by: Rachel Leeson. image credit: HIV on macrophages, Reconfirming the Traditional Model of HIV Particle Assembly. Gross L, PLoS Biology Vol. 4/12/2006, e445.   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 […]

Facundo Batista appointed Chief Editor of The EMBO Journal

Feb 3, 2021 Ragon Culture

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 […]

Mere Semantics: Natural Language Processing in Viral Evolution

Jan 14, 2021

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 […]

Calming the storm: Dendritic Cells Regulate IL-6

Dec 22, 2020

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 […]

Cellular connections found between nervous and immune systems

Dec 17, 2020

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, […]
