DNA vaccine encoding heat shock protein 90 protects from murine lupus

Background Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the presence of autoantibodies to multiple self-antigens, including heat shock proteins (HSP). Because of the increased expression of HSP90 and abnormal immune responses to it in SLE, we investigated whether an HSP90 DNA vaccine could modulate the development and clinical manifestations of SLE in lupus-prone mice. Methods (NZB x NZW)F 1 (NZB/W) mice...
