GSE130975: RNA seq on SP specific CD8+ T cells, Ly49+ and Ly49-CD8+ T cells from MOG and MOG + SP immunized mice [RNA-Seq]

Bulk RNA sequencing

In experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis (MS), induction generates successive waves of clonally expanded CD4+, CD8+, and gd+ T cells in the blood and central nervous system, similar to gluten challenge studies of Celiac patients. In MS patients, we also observe major expansions of CD8+ T cells. In EAE, we find that most expanded CD4+ T cells are specific for the inducing myelin peptide MOG35-55 but in contrast, peptide ligands derived from a yeast peptide-MHC display library for some of the clonally expanded CD8+ T cells inhibit disease by suppressing the proliferation of MOG-specific CD4+ T cells. These results suggest the induction of autoreactive CD4+ T cells triggers an opposing mobilization of regulatory CD8+ T cells.
