NKG2A expression was higher in CD56bright NK cells than in CD56dim NK cells (controls, 42.7±4.6% vs. 12.9±3.5%, p = 0.001; inactive SLE, 45.1±5.6% vs. 14.9±2.8%, p = 0.001; active SLE, 45.0±6.9% vs. 24.6±6.5%, p = 0.048) (Fig 5D and Fig 5E). The gene discussed is KLRC1; the disease is systemic lupus erythematosus.
