Leukocyte Immunoglobulin Like Receptor Subfamily B, Member 2 (LILRB2) Antibody

Background

LILRB2, also known as Leukocyte Immunoglobulin-Like Receptor Subfamily B Member 2, ILT4 (Immunoglobulin-Like Transcript 4), or CD85d, is an inhibitory receptor expressed on immune cells, especially on myeloid cells, such as monocytes, macrophages, dendritic cells, and some granulocytes. It is part of the LILR family (leukocyte immunoglobulin-like receptors), which is encoded within the LRC (Leukocyte Receptor Complex) on chromosome 19q13.4. LILRB2 plays a major role in immune homeostasis by binding to MHC class I molecules and other ligands, leading to suppression of immune responses. This makes it a central player in controlling inflammation, self-tolerance, and response to chronic infections and tumors.
