LILRA6, Leukocyte Immunoglobulin-like Receptor subfamily A, member 6, also called CD85b and ILT8.The leukocyte immunoglobulin-like receptor (LILR) multigene family is a family of paired receptors composed of inhibitory and activating forms, which are highly homologous in their extracellular regions and different in their intracellular regions. LILRA6 is the activating forms, which have two or four Ig-like domains with short cytoplasmic tail and associate with FcRγ chain containing immunoreceptor tyrosine-based activation motifs. LILRA6 (ILT8/CD85b) and LILRB3 (ILT5/CD85a) are paired receptors expressed by myelomonocytic leukocytes. LILRA6 and LILRB3 have high similarity in their extracellular domain, making them further difficult to distinguish., and mAbs generated against these receptors bind to neutrophils. In addition, LILRA6 is correlated with susceptibility to atopic dermatitis. LILRA6 on the surface of macrophages induces and regulates cytokines such as IL-4, IL-10, IL-17, TNFα and IFN-γ.
