We evaluated the specific IgG antibodies against heat shock proteins (HSPs) in cerebrospinal fluids (CSF) from patients with multiple sclerosis (MS). ELISA was employed to examine IgG antibodies against ten HSPs (HSP27, α A and α B crystallins, HSP60, CCT, Mycobacterium bovis HSP65, Escherichia coli GroEL, HSP70, HSC70 and HSP90) in CSF from 30 patients with MS, and 25 patients with motor neuron diseases (MND). Significantly higher antibody titers against HSP70 and HSC70 proteins were found in CSF obtained from patients with MS as compared with MND independent of CSF total protein, IgG concentrations and IgG indices, respectively. The antibody titers against HSP70 were indicated to be significantly higher in the progressive cases than in cases of remission. The results suggest that IgG antibodies against specific types of HSPs especially HSP70 family proteins (HSP70 and HSC70) in CSF may play an important role in the pathophysiology of MS through the modification of immune response and cytoprotective functions of molecular chaperons.
