Patients with multiple sclerosis (MS) show a high prevalence of myelin-reactive CD8+ and CD4+ T-cell responses, which are the putative effectors/modulators of CNS neuropathology. Utilizing a novel combination of short-term culture, CFSE-based sorting and anchored PCR, we evaluated clonal compositions of neuroantigen-targeting T-cells from RRMS patients and controls. CDR3 region analysis of TCRβ chains revealed biased use of specific TCRBV-bearing CD4+ clones. CD8+ clones showed homology to published TCR from CNS-infiltrating T-cells in MS lesions. These studies are the first description of TCR usage of CNS-specific CD8+ T-cells and provide insights into their potential regulatory role in disease.
