Mild Injury May Render Brain Cells Vulnerable to Immune Attack

A seemingly mild "insult" to the brain could sensitize neurons to attack by immune system proteins that are otherwise protective, researchers have found. The finding could explain why sufferers of Alzheimer's and other neurodegenerative diseases significantly worsen following such insults. The scientists believe that drugs to selectively inhibit the immune proteins could reduce the rate of neural damage in a wide range of neurodegenerative diseases. Such drugs could also protect other organs against damage from autoimmune diseases such as lupus and rheumatoid arthritis, in which the immune system attacks body tissues.
