ILT4, also known as CD85d, LIR-2, and LILRB2, is closely related to mouse PIR-B and is primarily expressed on monocytes, dendritic cells, and neutrophils. The ECD of human ILT4 shares 76% aa identity with chimpanzee ILT4 and 74%, 81%, 33%, 52%, 77%, 61%, and 64% aa identity with human ILT1, 2, 3, 5, 6, 7, and 8, respectively. ILT4 binds to classical MHC I proteins as well as the non-classical HLA-G1 and HLA-F molecules. It competes with CD8 alpha for MHC I binding but does not compete with KIR2DL1. Ligation of ILT4 induces tyrosine phosphorylation within its cytoplasmic ITIMs, association with SHP-1, and inhibition of stimulatory signaling. ILT4 activation promotes the development of tolerogenic dendritic cells and the subsequent induction of regulatory T cells and CD4+ T cell anergy.
