γδ T cells subsets exhibit distinct surface protein fingerprints. Total γδ T cells were gated on (A) CD161 and (B) HLA-DR versus Vδ1. Vδ1⁻ (C) and Vδ1⁺(D) T cells were gated on CD45RA versus CD27,. An example of biaxial density plots from one donor is shown. Comparison of CD161 expression on (E) T_CM cells and (F) T_EM cells in Vδ1⁺ and Vδ1⁻ populations showing elevated CD161 expression in Vδ1⁻ cells (p < 0.0001)
