Background Information

Lymphocyte-activation protein 3 (LAG-3) belongs to the immunoglobulin superfamily and shares sequence homology, exon/intron organization and chromosomal localization to CD4. LAG-3 cDNA encodes a 498 amino acid transmembrane protein with 4 extracellular Ig-like domains. The expression of LAG-3 is undetectable in resting peripheral blood lymphocytes but it is induced in activated T and NK cells. Human MHC Class II molecules can bind to LAG-3 and are considered as receptors for LAG-3 on B cells and dendritic cells. LAG-3 is proven to be an inhibitory receptor on activated T cells. Crosslinking of LAG-3 on activated T cells with an anti-LAG-3 antibody inhibits T cell proliferation and cytokine secretion. Blocking or modulating LAG-3 can potentially enhance anti-tumor immune responses by preventing immune suppression.
