Oligodendrocyte-specific protein (OSP) is concentrated in CNS myelin and is a potential autoantigen in the development of multiple sclerosis (MS).

We performed proliferation assays with lymphocytes from MS patients and normal controls.

OSP peptide-induced proliferation was common in relapsing-remitting MS and controls samples but was less pronounced in samples from secondary progressive MS subjects.

These data demonstrate that OSP-reactive T cells are part of the normal immune repertoire and therefore have the potential to contribute to the pathogenesis of MS.

Given the lack of specificity to MS, OSP-reactive T-cells are unlikely to be solely responsible for the disease process.
