We investigated the relationships between acute exercise and CXCR4 expression on natural killer (NK) cells. Peripheral blood mononuclear cells (PBMCs) were cultured with cortisol and analyzed for CXCR4 expression on CD3(-)/CD56(+) NK cells and NK cell migration activity. To determine the effect of exercise, we isolated PBMCs from subjects before and after a 90-min exercise at 70% peak O2 uptake (V̇o2peak) and determined the changes in CXCR4 expression on NK cells after exercise. We cultured PBMCs with plasma obtained before and after exercise and with the glucocorticoid antagonist RU-486 to determine NK cell migration activity and the effects of cortisol on CXCR4 expression in vitro. Cortisol treatment increased CXCR4 expression (P < 0.05) and migration activity (P < 0.05) of NK cells. Exercise did not affect CXCR4 expression on NK cells, whereas incubating them with postexercise plasma significantly increased CXCR4 expression (P < 0.05) and migration activity (P < 0.05). RU-486 blocked cortisol-induced CXCR4 upregulation on NK cells, but only partially blocked (7%) CXCR4 upregulation when PMBCs were incubated with postexercise plasma. Thus acute exercise increases CXCR4 expression on NK cells and their migration activity and may contribute to NK cell redistribution after acute exercise; however, cortisol did not appear to be the primary mediator of augmented CXCR4 expression."xsd:string |
