Abstract

We sought to compare the ongoing CD8+ cytotoxic T lymphocytes (CTL) immune response of MS patients to self and viral antigens. Using 51Cr release and tetramer staining assays, we found that the CTL response against VP1, the major capsid protein of the polyomavirus JC (JCV), was significantly higher than the one against epitopes of MBP and PLP. The JCV-specific CTL response was also significantly stronger in MS patients than healthy control subjects. These findings may shed a new light on the recent events related to the development of progressive multifocal leukoencephalopathy in three natalizumab-treated patients.
