In addition, the level of serum LDL-C in CAD patients was significantly positively correlated with the proportions of CD69+ cells (r=0.3368, P=0.0446), NKG2D+ cells (r=0.5131, P=0.0014), and NKp46+ cells (r=0.3384, P=0.0435); r=0.3368) in Vδ2+T cells (Figures 6C–E). The gene discussed is KLRK1; the disease is coronary artery disorder.
