Heat shock proteins and experimental autoimmune encephalomyelitis II: environmental infection and extra-neuraxial inflammation alter the course of chronic relapsing encephalomyelitis

We wished to study how infections might trigger relapses of autoimmune diseases such as multiple sclerosis (MS) and encephalomyelitis (EAE). We hypothesized that immune responses to heat shock proteins (hsp) induced by an infection could modulate responses to autoantigens. We induced extra-neuraxial inflammation in SJL mice housed either in specific-pathogen free (SPF) or conventional facilities. Mice in conventional housing are continuously …
