Infections May Trigger Autoimmunity Via Rare, But Normal Process

Summary:
New findings from researchers at The Wistar Institute suggest that autoimmunity may result from the rare confluence of entirely normal events. The study tracked a mildly self-reactive subset of the body's so-called memory B cells - long-lived immune cells that stand ready to respond to pathogens the immune system has previously encountered.

PHILADELPHIA - The body's immune system has sophisticated safeguards in place to prevent it from turning its destructive power against the body's own cells. Immune cells with the capability of attacking the self are readily identified in healthy individuals, and these cells are typically purged from the system. Autoimmune disorders, such as lupus, arthritis, and diabetes, are understood to result from breakdowns in those protections - they are seen as departures from the healthy norm.
