Chromatin accessibility of PD1 knockout tissue resident memory T cells
OT1 cells were sorted on : Size, singlets live dead CD8 Va2 + and donor OT1 using congenic markers to distinguish donor cells (eg CD45.2, Thy1.1, Thy1.2, CD45.1) from recipient (host cells), and between PD1+/+ OT1 and PD1-/- OT1 donors. Overall design: ATAC-Seq
