Vitamin A directs immune cells to intestines
A key set of immune cells that protect the body from infection would be lost without directions provided by vitamin A, according to a recent study.
Potential new HIV therapy seen in immune cells
A research team, led by Weill Cornell Medical College scientists, has discovered a way to limit replication of the most common form of HIV at a key moment when the infection is just starting to develop.
