Studies show early detection, prompt ARV treatment provide hope for the elimination of HIV

Could early treatment with antiretroviral (ARV) therapy help the body fight off HIV? Researchers affiliated with the Sub-Saharan African Network for TB/HIV Research Excellence (SANTHE) are convinced that early ARV therapy is critical to the treatment of HIV.   Researchers at the University of KwaZulu-Natal (UKZN) in Durban, South Africa are conducting studies they believe […]

New vaccine strategy boosts T-cell therapy

Super-charging a treatment for leukemia also makes it effective on solid tumors. Anne Trafton | MIT News Office A promising new way to treat some types of cancer is to program the patient’s own T cells to destroy the cancerous cells. This approach, termed CAR-T cell therapy, is now used to combat some types of […]

Breaking the Code: How is a mother’s immunity transferred to her baby?

Ragon Institute-led study identifies factors contributing to placental transfer of antibodies CAMBRIDGE, Mass. – One of the most successful interventions in reducing infectious disease worldwide, vaccination still has limited effectiveness in protecting one group of patients – newborn infants. Now a study based at the Ragon Institute of MGH, MIT and Harvard has determined how […]

Early antiretroviral treatment may preserve key immune responses to HIV

Ragon Institute study findings could pave the way to vaccine development CAMBRIDGE, Mass. – Instituting combination antiretroviral (ART) treatment at the earliest stages of HIV infection may allow the generation of functional CD8 “killer” T cells and preservation of the CD4 helper T cells that are the virus’s primary target.  Investigators from the Ragon Institute […]

New immune markers of exposure to Mycobacterium tuberculosis challenge decades of clinical practice

Tuberculosis (TB) is the leading infectious cause of death worldwide, and is caused by the slow growing bacterium Mycobacterium tuberculosis (Mtb). Because the time between infection and disease can be long – years or even decades – a major challenge for public health is knowing who is at risk for becoming ill so that they […]
