From the ovarian cancer lesion, we classified a total of 7967 T and NK cells into eight subtypes: CD4+ T cells (CD4 IL7R; CD3D+ CD4+), regulatory CD4+ T cells (Tregs FOXP3; CD4, FOXP3), CD8+ T cells (CD8 GZMK, CD8 GZMH; CD3D+ CD8+), NK cells (NK CD56, NK IL7R; NCAM1, GNLY, TYROBP, NKG7), NKT cells (CD3D, CD8A, FCGR3A, GNLY), and Innate Lymphoid Cells (ILCs; CD3D) (Figures 5A, C and S10A). The gene discussed is CD8A; the disease is ovarian carcinoma.
