Coxsackie B4 virus

Coxsackie B4 virus is a virus which can trigger an autoimmune reaction[?] which results in an attack on the beta cells. If destroyed, the person becomes a Type I diabetic, no longer producing insulin internally. There are several viruses in the Coxsackie family and many of them seem to evoke this response, as do several other agents. A genetic predispostion to this seems to be required. A particular HLA body type has been associated with that genetic predispostion.
