Brain-infiltrating CD8+ T cell chromatin accessibility after acute infection and during CNS autoimmunity [ATAC-Seq]. Brain-infiltrating CD8+ T cell chromatin accessibility after acute infection and during CNS autoimmunity [ATAC-Seq]
收藏资源简介：
CD8+ T cells play a pivotal role in eliminating pathogens or tumors, but they equally exert tissue damage in autoimmune or chronic inflammatory diseases. While the mechanisms regulating the differentiation of CD8+ T cells in chronic infections and cancer are just beginning to be unraveled, we still lack knowledge about how this unfolds in autoimmune diseases. Here, we investigated in a model of chronic central nervous system autoimmunity, the transcriptional and epigenetic landscape of autoreactive brain infiltrating CD8+ T cells and how these cells diverge from classical long-lived memory CD8+ T emerging after virus infection. Overall design: Chromatin accessibility of brain-infiltrating WT and Tox -/- P14 CD8+ T cells adoptively transfered in WT and MOG-GP recipient mice following intracranial infection with LCMV-GP.
