The association between multiple sclerosis and Epstein-Barr virus infection could involve Epstein-Barr virus-specific T cells, provided that these T cells get access to the intrathecal compartment.

We report that CD4(+) T cells from the cerebrospinal fluid of six out of six multiple sclerosis patients, and four out of six patients with other neurological diseases, recognized autologous B cells transformed with Epstein-Barr virus.

The cerebrospinal fluid T-cell responses were predominantly HLA-DR restricted.

These T cells did not recognize B cells activated through stimulation of CD40 or the inducible autoantigen alphaB crystalline.

These findings support that the immunological response to Epstein-Barr virus could contribute to the pathogenesis of multiple sclerosis.
