Recombinant Human TIM-3/HAVCR2 Protein (His Tag)

Hepatitis A virus cellular receptor 2 (HAVCR2); formerly known as T cell immunoglobulin and mucin domain-3 (TIM-3); is a transmembrane glycoprotein expressed on the surface of terminally differentiated Th1 cells but not on Th2 cells. It was the first surface molecule that specifically identifies Th1 cells in both mice and human. Recently; identification of Galectin-9 as a ligand for TIM-3 has established the TIM-3-Galectin-9 pathway as an important regulator of Th1 immunity and tolerance induction. Engagement of Tim-3 by its ligand galectin-9 negatively regulates IFN-gamma secretion and influences the ability to induce T cell tolerance in both mice and man. It suggests a novel paradigm in which dysregulation of the TIM-3-galectin-9 pathway could underlie chronic autoimmune disease states; such as multiple sclerosis. Recent work has explored the role of TIM-3 in systemic lupus erythematosus (SLE); and their results indicate that TIM-3 may represent a novel target for the treatment of SLE. Numerous studies have demonstrated that Tim-3 influences autoimmune diseases; including diabetes and multiple sclerosis; and its role in other inflammatory diseases including allergies and cancer is beginning to become clear. In tumor rejection model; soluble form of Tim-3 (sTim-3) significantly impaired T cell antitumor immunity; evidenced by decreased antitumor CTL activity and reduced amount of tumor-infiltrating lymphocytes in tumor. sTim-3 as an immunoregulatory molecule that may be involved in the negative regulation of T cell-mediated immune response.Immune CheckpointImmune Checkpoint Detection: ELISA Antibodies   Immune Checkpoint Detection: IP Antibodies   Immune Checkpoint Detection: WB AntibodiesImmune Checkpoint ProteinsImmune Checkpoint Targets   Co-inhibitory Immune Checkpoint Targets Immunotherapy   Cancer Immunotherapy   Targeted Therapy
