Barczak Lab Leads Study Showing Omicron Subvariants Shed Virus for Similar Periods and Symptoms Alone Do Not Signal Safety
Oct 22, 2025 Features
A new JCI Insight study led by the POSITIVES team and the Barczak Lab at the Ragon Institute followed people with mild COVID-19 to see whether newer Omicron subvariants behave differently over time. Despite ongoing viral evolution, the team found core features—how much viral nucleic acid is found in the nose and how long people […]
Ragon–Scripps Collaboration Shows Single mRNA Shot Can Start Several HIV-Blocking Antibody Paths at Once
Oct 20, 2025 Features
A new study co-led by the Batista Lab at the Ragon Institute and Scripps/IAVI shows that a single mRNA-based vaccine mix can jump-start the early steps toward several promising HIV-fighting antibodies at the same time. Because HIV is extremely diverse, a successful vaccine would likely need to train the immune system along multiple routes, not […]
W.M. Keck Foundation to support Ringel Lab research on healthy aging at MIT – MIT Biology
Oct 10, 2025 Features
A prestigious grant from the W.M. Keck Foundation to Assistant Professor of Biology Alison Ringel will support groundbreaking healthy aging research at MIT. Ringel, also a Core Member of the Ragon Institute, will draw on her background in cancer immunology to create a more comprehensive biomedical understanding of the cause and possible treatments for aging-related decline. “It is […]
Kwon Lab Study Links Gut Immune Cell Metabolism to Barrier Damage in HIV
Sep 11, 2025 Features
A new study led by investigators at the Kwon Lab and collaborators shows how energy use by gut immune cells can weaken the intestinal lining in people living with HIV, even when the virus is controlled by treatment. The work identifies a metabolic switch inside these cells as a promising target to help protect the […]
