The LILRB4/CD85k/ILT3 protein is a multifaceted inhibitory receptor in immune regulation that significantly downregulates multiple immune responses. As a receptor for FN1 and integrin ITGAV/ITGB3, LILRB4/ILT3 inhibits IgE-mediated mast cell activation, KITLG/SCF-mediated mast cell activation, and antibody production by memory/marginal zone B cells through the ITGAV/ITGB3 interaction. LILRB4/CD85k/ILT3 Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived LILRB4/CD85k/ILT3 protein, expressed by HEK293 , with C-His labeled tag. The total length of LILRB4/CD85k/ILT3 Protein, Cynomolgus (HEK293, His) is 238 a.a., with molecular weight of 35-42 kDa.

Cynomolgus

LILRB4/CD85k/ILT3, an inhibitory receptor intricately involved in immune regulation, plays a crucial role in down-regulating immune responses. It serves as a receptor for FN1 and integrin ITGAV/ITGB3, exerting inhibitory effects on IgE-mediated mast cell activation and KITLG/SCF-mediated mast cell activation. Through its interaction with ITGAV/ITGB3, LILRB4/ILT3 further inhibits antibody production by memory and marginal zone B cells, likely by suppressing their differentiation into plasma cells. This multifaceted receptor extends its inhibitory influence to diverse immune functions, such as suppressing IFNG production by CD8 T cells, CD4 T cells, and natural killer cells, as well as inhibiting antigen presentation by dendritic cells to T cells, preventing T cell activation. Additionally, LILRB4/ILT3 effectively inhibits lipopolysaccharide-mediated neutrophil-dependent vascular injury and contributes to the suppression of the allergic inflammatory response by impeding the infiltration of neutrophils and eosinophils while preventing mast cell degranulation. Its interactions, particularly when tyrosine phosphorylated, with SH2 domain-containing phosphatases PTPN6/SHP-1 and PTPN11/SHP-2 enhance the inhibition of mast cell activation.
