Lymphocyte activation gene-3 (LAG-3) is a CD4-related, activation-induced cell surface molecule that binds to MHC class II with high affinity. In this study, we used four experimental systems to reevaluate previous suggestions that LAG-3(-/-) mice had no T cell defect. First, LAG-3(-/-) T cells exhibited a delay in cell cycle arrest following in vivo stimulation with the superantigen staphyloco...
Lymphocyte Activation Gene-3 (LAG-3) is a transmembrane protein that binds MHC class II, enhances regulatory T cell activity, and negatively regulates cellular proliferation, activation, and homeostasis of T cells. Programmed Death 1 (PD-1) also negatively regulates T cell function. LAG-3 and PD-1 are both transiently expressed on CD8 T cells that have been stimulated during acute activation. H...
One of the most important steps forward in management cancer was discovery immunotherapy. It has become an essential pillar treatment paradigm patients. Unfortunately, despite various options presented with immune checkpoint inhibitors (ICIs), benefit is still limited to select patients and vast majority these gain either minimal or eventually progress, leaving unmet need for development novel ...
Lymphocyte activation gene-3 (LAG-3) is a CD4-related transmembrane protein expressed by regulatory T cells that binds MHC II on APCs. It is shown in this study that during Treg:DC interactions, LAG-3 engagement with MHC class II inhibits DC activation. MHC II cross-linking by agonistic Abs induces an ITAM-mediated inhibitory signaling pathway, involving FcgammaRgamma and ERK-mediated recruitme...
Lymphocyte Activation Gene - 3 (LAG-3) is an immune checkpoint molecule that regulates both T-cell activation and homeostasis. However, the molecular mechanisms underlying LAG-3's function are generally unknown. Using a model in which LAG-3 blockade or absence reliably augmented homeostatic proliferation in vivo, we found that IL-2 and STAT5 are critical for LAG-3 function. Similarly, LAG-3 blo...
Lymphocyte activation gene-3 (LAG-3) is a cell-surface molecule with diverse biologic effects on T cell function. We recently showed that LAG-3 signaling is important in CD4+ regulatory T cell suppression of autoimmune responses. Here, we demonstrate that LAG-3 maintains tolerance to self and tumor antigens via direct effects on CD8+ T cells using 2 murine systems. Naive CD8+ T cells express lo...
Epithelial ovarian cancer requires the development of treatments according to histology, and immune checkpoint inhibitors may be a new therapeutic strategy in clear cell carcinoma (OCCC). Lymphocyte activation gene 3 (LAG-3), an checkpoint, is poor prognostic factor target for several malignancies. In this study, we demonstrated correlation between LAG-3 expression clinicopathological features ...
