Patients in Group 2 showed underexpression of the activating receptors NKp46. NKp46+ILC3s, while normal numbers of ILC1 and ILC2 subsets were found in the intestine of ScanT mice. Thus, group 1 NKp46+ ILCs interact with the complement pathway, via NKp46, revealing a cross-talk between two partners of innate immunity in the response to an invasive bacterial infection. Altogether, our data suggest that the decreased expression of activating receptors NKp30, NKp46, NKG2D, and DNAM-1 on peripheral blood NK cells is positively associated with GC progression, and that TGF-β1-mediated NK cell suppression may be a therapeutically targetable characteristic of GC. UniRef. The NK activating signal mainly involves the NKp30 natural cytotoxicity receptor, and not the NKp46 or NKp44 receptor . These findings shed light on rhIL23R-CHR/Fc as a promising candidate therapy for the treatment of psoriasis. Indeed, even though circulating NK cells express higher levels of CD16 than of NKp46, we observed in vitro that NK cell engager molecules (NKCEs) targeting NKp46 were at least equivalent or more effective to mediate anti-tumor activity than the regular IgG1 mAb targeting the same antigens, suggesting that engaging NKp46 was a more efficient NKp30, NKp46, NKG2D, NKp80 and 2B4 expression was analyzed by flow cytometry on NK cells from 59 patients with cervical cancer and squamous intraepithelial lesions.
