In a recent study, Harrison et al. (Science 2019;363;eaat6280) report that RORγt-expressing skin commensal-specific T cells rapidly respond to tissue wounding by producing type 2 T helper cell (Th2) cytokines in mice. The cells constitutively coexpress GATA-3 and type 2 cytokine mRNAs that are translated after injury. These T cells act as sentinels, linking T cell receptor (TCR) recognition of commensals, tissue damage, and wound repair.
