examined circulating ILC in the peripheral blood of 49 SLE patients and showed an increase in ILC1 (defined as Lin−CD127+CRTH2−CD117−) compared with healthy controls, while ILC2 (Lin−CD127+CRTH2+) and ILC3 (including 2 subpopulations, defined as Lin−CD127+CRTH2−CD117+NKp44+ or NKp44−) were decreased (28). The gene discussed is NCR2; the disease is systemic lupus erythematosus.
