Immune system may also help brain -- Newsday.com

Researchers at the Weizmann Institute of Science in Israel have discovered that the immune system may play a role in stimulating the growth of brain cells. According to the researchers, immune cells called T-lymphocytes can help stimulate the growth of neurons in the brain.

"T-lymphocytes normally enter the brain to patrol for signs of infection. But scientists have discovered that these immune cells recognize a normal brain protein as foreign and mount an immune response by pumping out activated microglia, cells that produce inflammation. These microglia support the birth of new neurons in these brain regions."
