Abstract/OtherAbstract:
In this study, acute and chronic brain and spinal cord lesions, and normal appearing white matter (NAWM), were resected post-mortem from a patient with aggressive relapsing-remitting multiple sclerosis (MS). T-cell infiltrates from the central nervous system (CNS) lesions and NAWM were separated and characterized in-vitro. All infiltrates showed a proliferative response against multiple myelin peptides. Studies of the T-cell receptor (TCR)Vbeta and Jbeta usage revealed a very skewed repertoire with shared complementarity-determining region (CDR)3 lengths detected in all CNS lesions and NAWM. In the acute lesion, genomic profiling of the infiltrating T-cells revealed up-regulated expression of TCRalpha and beta chain, retinoic acid-related orphan nuclear hormone receptor C (RORC) transcription factor, and multiple cytokine genes that mediate Th17 cell expansion. The differentially expressed genes involved in regulation of Th17 cells represent promising targets for new therapies of relapsing-remitting MS.
