After being infected with simian immunodeficiency virus (SIV) in a laboratory study, rhesus macaques that had more of a certain type of immune cell in their gut than others had much lower levels of the virus in their blood, and for six months after infection were better able to control the virus.

University of Cincinnati (UC) researchers have found that an imbalance in the regulation of certain T cells—the cells in the body that fight off infection or attack the system in certain autoimmune diseases—may put certain people at a higher risk of having recurrent cases of Clostridium difficile, or C. Diff, infection.

Scientists at The Scripps Research Institute have made an important discovery about the internal programming of B cells, the immune cells that make antibodies against infections.
