Scientists discover how to grow cells that suppress immune responses
Researchers at Washington University School of Medicine in St. Louis have discovered how to grow a little-understood type of human immune cell. The cells, known as T-regulatory cells type 1 (Tr1), are thought to turn off unnecessary immune reactions and to block the action of immune cells that otherwise would attack the body and cause dangerous inflammation. The findings are reported in the Jan. 23 issue of the journal Nature. more
