GAD antibodies & HHV-6 limbic encephalitis – a case of molecular mimicry?

In All, Autoimmune Disease, CNS Disease, CNS Dysfunction, Encephalitis & Encephalopathy, Epilepsy and Seizures, Host Cell Interaction by Kristin Loomis

A fifth case of limbic encephalitis associated with GAD antibodies and HHV-6 infection has been reported, this time in an immunocompetent woman with chromosomally integrated HHV-6, epilepsy, and psychosis. The patient’s condition improved (with a drop in GAD antibody titers and stabilization of psychotic symptoms) in response to three weeks of antiviral therapy but relapsed when antiviral therapy was withdrawn.

Epstein-Barr Virus and Human herpes virus 6 Type A DNA Enhance IL-17 Production in Mice

In All, Autoimmune Disease, News by hhv6foundation

Since both HHV-6 and EBV have been associated with an increased risk of autoimmune disease development, a group at the American University of Beirut studied whether viral DNA might be capable of triggering IL-17, a cytokine associated with autoimmune disease. They injected BALB/c mice intraperitoneally with either EBV or HHV-6A DNA. They found that both IL-17 and IL-23 were markedly elevated.
