title: Cerebrospinal fluids containing anti-HSP70 autoantibodies from multiple sclerosis patients augment HSP70-induced proinflammatory cytokine production in monocytic cells.
abstract: Anti-heat shock protein 70 (HSP70) autoantibodies are found in cerebrospinal fluids (CSF) from patients with multiple sclerosis. These autoantibodies cross-reacted not only with HSP70 and heat shock cognate protein 70 (HSC70), but also with a bacterial homologue, DnaK. CSF with a high anti-HSP70 autoantibody titer enhanced HSP70-induced proinflammatory cytokine and chemokine production in the human monocytic cell line, THP-1. Thus, anti-HSP70 autoantibodies in the CSF of multiple sclerosis patients may play a pathophysiological role in enhancing inflammation.
