In inflammation, some regulatory T (Treg) cells lose FoxP3 expression and become exTreg cells. Ley and colleagues mapped mouse Treg and exTreg cell transcriptomes to a human peripheral blood mononuclear cell single-cell RNA-sequencing dataset with surface markers (CITE-seq) and identify human exTreg cells as cytotoxic CD4+ T cells.
