Can viruses induce autoimmunity?

Available data indicate that viral-induced autoimmunity can be activated through multiple mechanisms including molecular mimicry, epitope spreading, bystander activation, and immortalization of infected B cells.

How do viruses cause autoimmunity?

People with autoimmune disease aren’t typically considered immunocompromised, unless they take certain medications that slow down their immune system. “The connotation for immunocompromised is that the immune function is reduced so you are more prone to infection,” Dr. Khor says.
