Central nervous system beckons attack in MS-like disease

Eliminating a molecular signal can help protect a neuron (show here) from destructive immune system cells.It may sound like a case of blame the victim, but researchers at Washington University School of Medicine in St. Louis have shown that cells in the central nervous system can sometimes send out signals that invite hostile immune system attacks. In mice the researchers studied, this invitation resulted in damage to the protective covering of nerves, causing a disease resembling multiple sclerosis. The researchers found that they could prevent destructive immune cells from entering nervous system tissue by eliminating a molecular switch that sends “come here” messages to immune cells.
