Description

This recombinant monoclonal antibody is developed as a research-grade biosimilar to OR502, targeting LILRB2 (Leukocyte Immunoglobulin-Like Receptor B2), also known as ILT4 or CD85d. LILRB2 is an inhibitory receptor predominantly expressed on myeloid cells, including monocytes, macrophages, and dendritic cells, where it functions as a critical immune checkpoint by delivering inhibitory signals upon ligand binding. The receptor recognizes classical and non-classical MHC class I molecules as well as angiopoietin-like proteins, subsequently suppressing immune cell activation and promoting immune tolerance. LILRB2 plays a significant role in various pathological conditions, including cancer immune evasion, where tumor cells exploit this pathway to suppress anti-tumor immunity, and inflammatory disorders where dysregulated LILRB2 signaling contributes to disease progression.

The reference antibody OR502 has been utilized in immunological research to investigate LILRB2-mediated immune regulation and its therapeutic potential as an immune checkpoint target. This biosimilar antibody serves as a valuable research tool for studying myeloid cell biology, tumor-immune interactions, and the development of novel immunotherapeutic approaches targeting the LILRB2 pathway.

Usage

It is a non-therapeutic biosimilar antibody, owning the same variable region from the corresponding approved therapeutic antibody. In conclusion, it is a research-grade biosimilar antibody and expressed in mammalian cell, which can be directly used as positive controls in drug discovery or used for rapid verification of the biological functions of target protein.

Target Background

Function

Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C, HLA-G and HLA-F alleles. Involved in the down-regulation of the immune response and the development of tolerance. Recognizes HLA-G in complex with B2M/beta-2 microglobulin and a nonamer self-peptide (peptide-bound HLA-G-B2M) triggering differentiation of type 1 regulatory T cells and myeloid-derived suppressor cells, both of which actively maintain maternal-fetal tolerance. Competes with CD8A for binding to class I MHC antigens. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.

Subcellular Location

Cell membrane; Single-pass type I membrane protein.

Tissue Specificity

Expressed in monocytes and at lower levels in myeloid and plasmacytoid dendritic cells. Expressed in tolerogenic IL10-producing dendritic cells. Expressed in myeloid-derived suppressor cells during pregnancy. Detected at low levels in natural killer (NK)
