A group of immune cells that normally protect against inflammation in the gastrointestinal tract may have the opposite effect in multiple sclerosis (MS) and other brain inflammation-related conditions, according to a new study by Weill Cornell Medicine and NewYork-Presbyterian researchers. The results suggest that countering the activity of these cells could be a new therapeutic approach for such conditions.

Antibody protection against harmful forms of fungi in the gut may be disrupted in some patients with Crohn’s disease—a condition caused by chronic inflammation in the bowel—according to a new study by Weill Cornell Medicine investigators.

The master regulator behind the development of antibody-producing cells has been identified in a study by investigators at Weill Cornell Medicine. The findings provide new insight into the inner workings of the immune system and may help understand how tissues develop and how certain cancers arise.

Tuberculosis (TB) is a wily old killer, one of the deadliest infectious diseases in history and one of the few that naturally infects only humans. Researchers at Weill Cornell Medicine have been pursuing treatments for tuberculosis caused by Mycobacterium tuberculosis (Mtb) since the 1950s, and the program continues to excel at explaining TB’s mysteries and pushing toward more effective therapies.
