Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized untreated and concanavalin A (2.5 μg/ml for 72 hours) treated mouse splenocytes labeling LAG-3 with ab209238 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing increased membranous staining following treatment of mouse splenocytes with concanavalin A (2.5 μg/ml for 72 hours) (PMID 20391435; PMID 26318293; PMID 11527700; PMID 19631993).

The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) at 1/200 dilution (red).

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) at 1/1000 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab209238).

추가 정보

This supplementary information is collated from multiple sources and compiled automatically.

LAG-3 also known as CD223 is a transmembrane protein with a mass of approximately 70 kDa. It acts as a checkpoint molecule similar to CTLA-4 and PD-1 in the immune system. LAG-3 is expressed on activated T cells natural killer cells and some dendritic cells. It interacts with its ligand MHC class II leading to inhibition of cellular proliferation and cytokine secretion an important part of immune response regulation.
Biological function summary

LAG-3 is involved in maintaining immune homeostasis and preventing autoimmunity. It is not part of a complex but works in synergy with other immune checkpoint molecules. When interacting with MHC class II LAG-3 transmits inhibitory signals that attenuate immune cell responses. Its role in immune regulation helps to balance immune activation and tolerance which is essential for preventing tissue damage while protecting against pathogens.

Pathways

The inhibitory role of LAG-3 integrates into the T cell receptor (TCR) signaling pathway and is also linked to the PD-1 signaling pathway. In TCR signaling LAG-3 negatively regulates T cell activation. LAG-3 is functionally related to proteins like PD-1 and CTLA-4 sharing similar roles in immune checkpoint pathways that are critical for maintaining immune balance.

LAG-3 has links to cancer and autoimmune diseases. In cancer LAG-3 expression on tumor-infiltrating lymphocytes correlates with immune evasion by tumors. This relationship appears in various cancers including melanoma and renal cell carcinoma. In autoimmune diseases LAG-3's expression on regulatory T cells helps control conditions such as multiple sclerosis. It collaborates with CTLA-4 in modulating immune responses that prevent excessive immune activation and tissue damage associated with autoimmunity.

타겟 정보

Lymphocyte activation gene 3 protein. Inhibitory receptor on antigen activated T-cells (PubMed : 12209638, PubMed : 12421911, PubMed : 12672063, PubMed : 15100286, PubMed : 15634887, PubMed : 30580966, PubMed : 35413245, PubMed : 35761082, PubMed : 38483996, PubMed : 39209860). Delivers inhibitory signals upon binding to ligands, such as MHC class II, its main ligand present at the surface of antigen-presenting cells (APCs), and FGL1, which is secreted by hepatocytes and certain types of tumor cells (PubMed : 12209638, PubMed : 12421911, PubMed : 30349037, PubMed : 30580966, PubMed : 35413245, PubMed : 35761082, PubMed : 39209860). Ligand-binding initiates a signaling that inhibits the T-cell receptor (TCR) in the immunological synapse, preventing T-cell activation (PubMed : 12209638, PubMed : 12421911, PubMed : 12672063, PubMed : 15100286, PubMed : 15634887). Mechanistically, ligand-binding promotes (1) ubiquitination of the KIEELE motif, unleashing the RRFSALE motif from the membrane and (2) leading to the formation of condensates with the TCR component CD3E, thereby disrupting the association between CD3E and LCK and preventing TCR activation (PubMed : 40101708, PubMed : 40592325). May inhibit antigen-specific T-cell activation in synergy with PDCD1/PD-1 (PubMed : 21300912). Negatively regulates the proliferation, activation, effector function and homeostasis of both CD8(+) and CD4(+) T-cells (PubMed : 12209638, PubMed : 12421911, PubMed : 12672063, PubMed : 15100286, PubMed : 15634887). Also mediates immune tolerance : constitutively expressed on a subset of regulatory T-cells (Tregs) and contributes to their suppressive function (PubMed : 15485628). Also acts as a negative regulator of plasmacytoid dendritic cell (pDCs) activation (PubMed : 19201841).. The LAG3-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and escape destruction by the immune system, thereby facilitating tumor survival.. Secreted lymphocyte activation gene 3 protein. May function as a ligand for MHC class II (MHC-II) on antigen-presenting cells (APC), promoting APC activation/maturation and driving Th1 immune response.
