BACKGROUND T cell immunoglobulin mucin-3 (Tim-3) has been identified as a negative regulator of anti-tumor immunity. Recent studies highlight the important role of Tim-3 in the CD8(+) T cell exhaustion that takes place in both human and animal cancer models. However, the nature of Tim-3 expression in the tumor cell and the mechanism by which it inhibits anti-tumor immunity are unclear. This pre...
Tim-3 (T cell immunoglobulin and mucin domain 3), belonging to the member of the novel Tim family, has been confirmed that it plays a critical negative role in regulating the immune responses against viral infection and carcinoma. Recently, it has also been reported that the over-expression of Tim-3 is associated with poor prognosis in solid tumors. However, the role of Tim-3 in colorectal canc...
Psoriasis is a chronic skin disease mediated by Th17 and/or Th1 cells. Tim-3 is a cell surface molecule preferentially expressed on Th17 and Th1 cells. The interaction of Tim-3 with Tim-3 ligand inhibits cytokine production. To assess whether T cells in psoriasis have functional abnormalities, expression of cell surface Tim-3 on blood T cells producing interleukin-17 (Th17/Tc17 cells) or interf...
TIM-3 functions to enforce CD8+ T cell exhaustion, a dysfunctional state associated with the tolerization of tumor microenvironment. Here we report apoptosis of IFN-γ competent TIM-3+ population of tumor-infiltrating CD8+ T cells in colon cancer. In humans suffering from colorectal cancer, TIM-3+ population is higher in cancer tissue-resident relative to peripheral blood CD8+ T cells. Both the ...
Members of the T cell immunoglobulinand mucin-domain-containing molecule (TIM) family have roles in T cell-mediated immune responses. TIM-1 and TIM-2 are predominantly expressed on Th2 cells, whereas TIM-3 is preferentially expressed on Th1 and Th17 cells. We found that TIM-1 and TIM-3, but neither TIM-2 nor TIM-4, were constitutively expressed on mouse peritoneal mast cells and bone-marrow-der...
BACKGROUND T cell immunoglobulin-3 (TIM-3) has been established as a negative regulatory molecule and plays a critical role in immune tolerance. TIM-3 is upregulated in exhausted CD8(+) T cells in both chronic infection and tumor. However, the nature of TIM-3(+)CD4(+) T cells in the tumor microenvironment is unclear. This study is to characterize TIM-3 expressing lymphocytes within human lung c...
T-cell immunoglobulin mucin (TIM)-3 is an important member of the TIM gene family, which was thought to contribute to the progression of numerous types of cancer, including hepatocellular carcinoma (HCC); however, the mechanism underlying TIM-3 functions in HCC progression has not yet been extensively investigated. The present study aimed to investigate the function of TIM-3 in the metastasis o...
CD8(+) CTLs are adept at killing virally infected cells and cancer cells and releasing cytokines (e.g., IFN-γ) to aid this response. However, during cancer and chronic viral infections, such as with HIV, this CTL response is progressively impaired due to a process called T cell exhaustion. Previous work has shown that the glycoprotein T cell Ig and mucin domain-containing protein 3 (Tim-3) play...
T cell immunoglobulin mucin-3 (Tim-3) is an immune checkpoint inhibitor and its dysregulation has been related to T cell tolerance and many immune disorders, such as tumors and infection tolerance. However, the physiopathology roles of Tim-3 in innate immunity remain elusive. Here, we demonstrate that Tim-3 inhibits macrophage phagocytosis of L. monocytogenes by inhibiting the nuclear erythroid...
