FGFBP2 effectors aligned with previously described ITGB2 ITGAE T RM cells, while T RM (1), T RM (2) and cycling subsets aligned with CD103 T RM cells (Extended Data Fig. 5b ).

Analogous CD8 T cell subsets were seen in dataset 2 (Fig. 4d,e and Extended Data Fig. 5a ), with additional resolution for tissue-resident γδ T cells, and innate-like T cells (mucosal-associated invariant T cells and Vδ2Vγ9 cells).

KLRC1 (NKG2A) was expressed by CCL4 cells, while KLRC2 (NKG2C) was expressed by resident IL7R , T RM (1) and T RM (2) subsets (Extended Data Fig. 5c,d ).
