Leukocyte immunoglobulin-like receptor subfamily B member 4 is a protein that in humans is encoded by the LILRB4 gene.{{cite journal | vauthors = Cella M, Döhring C, Samaridis J, Dessing M, Brockhaus M, Lanzavecchia A, Colonna M | title = A novel inhibitory receptor (ILT3) expressed on monocytes, macrophages, and dendritic cells involved in antigen processing | journal = The Journal of Experimental Medicine | volume = 185 | issue = 10 | pages = 1743–51 | date = May 1997 | pmid = 9151699 | pmc = 2196312 | doi = 10.1084/jem.185.10.1743 }}{{cite journal | vauthors = Samaridis J, Colonna M | title = Cloning of novel immunoglobulin superfamily receptors expressed on human myeloid and lymphoid cells: structural evidence for new stimulatory and inhibitory pathways | journal = European Journal of Immunology | volume = 27 | issue = 3 | pages = 660–5 | date = March 1997 | pmid = 9079806 | doi = 10.1002/eji.1830270313 | s2cid = 2212182 | doi-access = free }}{{cite web | title = Entrez Gene: LILRB4 leukocyte immunoglobulin-like receptor, subfamily B (with TM and ITIM domains), member 4| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=11006}}

This gene is a member of the leukocyte immunoglobulin-like receptor (LIR) family, which is found in a gene cluster at chromosomal region 19q13.4. The encoded protein belongs to the subfamily B class of LIR receptors which contain two or four extracellular immunoglobulin domains, a transmembrane domain, and two to four cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs). The receptor is expressed on monocytic cells and transduces a negative signal that inhibits stimulation of an immune response. The receptor can also function in antigen capture and presentation. It is thought to control inflammatory responses and cytotoxicity to help focus the immune response and limit autoreactivity. LILRB4 has also been proposed to be a potential target for tumor immunotherapy. It has been shown to express on tumor-associated macrophages and negatively regulate immune response in tumor.{{cite journal | vauthors = Sharma N, Atolagbe OT, Ge Z, Allison JP | title = LILRB4 suppresses immunity in solid tumors and is a potential target for immunotherapy | journal = The Journal of Experimental Medicine | volume = 218 | issue = 7 | date = July 2021 | pmid = 33974041 | pmc = 8117208 | doi = 10.1084/jem.20201811 | url = https://doi.org/10.1084/jem.20201811 }} The expression of LILRB4 on monocytic myeloid leukemia cells supports infiltration and inhibits T cell proliferation. Multiple transcript variants encoding different isoforms have been found for this gene.
