To determine the phenotypic changes of activating NK cell receptors in γδ T cells and their subsets in CAD, the surface levels of NKp30, NKp46, and NKG2D in total γδ T cells, Vδ2+T cells, and Vδ2-T cells were compared between healthy individuals and CAD patients. The gene discussed is NCR3; the disease is coronary artery disorder.
