Flow cytometric analysis of human primary peripheral blood mononuclear cell (PBMC) labeling ILT-4 with ab224701 at 1/500 (right panel) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (left panel). Goat anti rabbit IgG (Dylight ^® 488, ab98462) at 1/2000 dilution was used as the secondary antibody.

Cells were stained with Alexa Fluor® 647-conjugated CD14 and rabbit IgG (Left) or ILT-4 (Right).

Data shown were gated on viable cells.

The CD14 co-staining result observed is consistent with what has been described in the literature (PMID : 10879687).

ILT-4 is expressed in monocytes and CD14 is an established marker for monocytes and macrophages (PMID : 23382732).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab224701).

Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized Human PBMC (human primary peripheral blood mononuclear cell) cells labeling ILT-4 with ab224701 at 1/50 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing co-staining with CD14 and cytoplasmic staining in PBMC cells. The nuclear counterstain is DAPI (blue). Counterstained with an Alexa Fluor^® 647 anti-human CD14 antibody at a 1/100 dilution (red).

The negative control is the secondary antibody only.

ILT-4 is expressed in monocytes (PMID : 10879687) and CD14 is an established marker for monocytes and macrophages (PMID : 23382732).

Supplementary information

ILT-4 also known as Immunoglobulin-like transcript 4 is a transmembrane protein with a molecular weight of approximately 45 kDa. The protein is part of the LILR family and is sometimes referred to as LILRB2 protein. ILT-4 is mainly expressed on myeloid lineage cells including monocytes and dendritic cells. The expression of ILT-4 is important for the modulation of the immune response. Biotinylated ILT-4 and biotinylated LILRB2 versions are used frequently in research to study their interactions and functions.

Biological function summary

ILT-4 plays an important role in the regulation of immune tolerance and inhibition. It is not part of a complex but interacts with other immune regulatory proteins. By binding to MHC class I molecules ILT-4 inhibits the activation of immune responses preventing over-activation and autoimmunity. The ILT-4 protein is critical for helping myeloid cells to maintain a balanced immune response often restricting unnecessary inflammation and promoting tolerance.

Pathways

ILT-4 influences immune signaling pathways such as those that control T cell receptor signaling. ILT-4 interactions with proteins like CD85d and other LILRA6 proteins showcase its involvement in negative regulatory signaling pathways. These pathways are essential for maintaining immune homeostasis and limiting immune-mediated damage during infections or tissue injury.

ILT-4 is implicated in cancer and autoimmune diseases such as multiple sclerosis. In cancers ILT-4 modulates the immune environment allowing tumors to evade immune surveillance. In the context of autoimmune disorders aberrant ILT-4 expression or function can lead to insufficient immune regulation contributing to disease progression. CD85d and LILRB2 proteins are also associated with these conditions further influencing ILT-4's role in disease mechanisms.

Target data

Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C, HLA-G and HLA-F alleles (PubMed : 11169396, PubMed : 12853576, PubMed : 16455647, PubMed : 20448110, PubMed : 27859042). 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 (PubMed : 16455647, PubMed : 20448110, PubMed : 27859042). Competes with CD8A for binding to class I MHC antigens. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions (PubMed : 11875462, PubMed : 12853576, PubMed : 9548455, PubMed : 9842885).
