A team led by researchers at Weill Cornell Medicine and Children’s National Hospital has developed a unique pre-clinical model that enables the study of long-term HIV infection, and the testing of new therapies aimed at curing the disease.

Gut bacteria play an important role in the body’s response to treatment for tuberculosis (TB), according to researchers at Weill Cornell Medicine and Memorial Sloan Kettering. Because current treatments for TB involve long courses of antibiotics, which are known to disrupt the balance of microbes in the gut, a better understanding of these interactions may help in predicting outcomes to therapy and suggest ways to improve it.

A team led by scientists at Weill Cornell Medicine has made a map identifying all the different RNA molecules that are derived from each gene in the brains of mice. It is the first map that depicts this important layer of biological diversity, called isoform variation, by cell type and across brain regions for the whole genome, and it contributes to neuroscientists’ ambitious goal of an ultra-detailed atlas of the brain.

A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study by Weill Cornell Medicine investigators.
