BACKGROUND: The lymphocyte activation gene-3 (LAG3) is a member of the immunoglobulin superfamily and binds MHC class II with high affinity (1) , negatively regulating T-cell function and homeostasis (2) . It is expressed in B, T, and NK cells, monocytes, and dendritic cells (3) , and acts to regulate T cell expansion (4) . LAG3 is also an important immune checkpoint protein, with anti-LAG3 antibodies activating T effector cells and affecting regulatory T cell functions. Furthermore LAG3 appears to act in a synergistic fashion with PD-1/PD-L1, suggesting that a dual antibody approach may prove useful in cancer immunotherapy.
