Lag - 3 , a Novel Lymphocyte Activation Gene
A number of cell surface structures are thought to belong to the Ig superfamily (IgSF) t because they contain at least one domain with a characteristic folding pattern, called the Ig fold (reviewed in reference 1) . Several of these molecules have critical functions in immune responses . In addition to ensuring specific antigen recognition (Ig, TCR), they may function as monomorphic ligands cri...
متن کاملLymphocyte activation gene-3 (LAG-3) expression and IFN-gamma production are variably coregulated in different human T lymphocyte subpopulations.
We evaluated the relationship between cytokine profile and the expression of the lymphocyte activation gene-3 (LAG-3) in both T cell clones and polyclonal T cell lines; LAG-3 is a CD4-like protein whose expression is reportedly restricted to Th1/0 cells and dependent upon IFN-gamma. We found that, while LAG-3 was expressed only by CD4+ T cell clones producing IFN-gamma, most CD8+ clones produci...
متن کاملHypersensitivity: T Lymphocyte-mediated (Type IV)
Five types of hypersensitivity reactions have been described: types I, II, III and V depend on the interaction of antigen with antibody and have been termed immediate; type IV depends on the interaction of antigen with T lymphocytes and has been called delayed-type hypersensitivity, or DTH. The DTH reaction involves cellular activation of T-helper cells (CD4+) and/or cytotoxic T cells (CD8+ CTL...
متن کاملRole of Lymphocyte Activation Gene-3 (Lag-3) in Conventional and Regulatory T Cell Function in Allogeneic Transplantation
Lag-3 has emerged as an important molecule in T cell biology. We investigated the role of Lag-3 in conventional T cell (Tcon) and regulatory T cell (Treg) function in murine GVHD with the hypothesis that Lag-3 engagement diminishes alloreactive T cell responses after bone marrow transplantation. We demonstrate that Lag-3 deficient Tcon (Lag-3(-/-) Tcon) induce significantly more severe GVHD tha...
متن کاملLymphocyte Activation Gene 3 (LAG-3) Modulates the Ability of CD4 T-cells to Be Suppressed In Vivo
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...
