Summary
To investigate the epigenetic landscape of tumor-reactive exhausted CD8+ T cells, ATAC-seq was performed on fluorescence-activated cell sorted CD8+ T cell subsets isolated from Lag3^iCreERT2^ Rosa26^LSL-tdTomato^ mice bearing B16-F10 melanoma tumors. Chromatin accessibility profiles were generated for lineage-traced LAG3^+tdTomato^+, LAG3^-tdTomato^+, and corresponding control CD8+ T cell populations isolated from tumors and draining lymphoid tissues. These data were used to characterize chromatin accessibility changes associated with exhausted, progenitor-like, and memory-like CD8+ T cell states and to define epigenetic relationships among lineage-traced T cell populations.
