Although T-cell immunoglobulin mucin 3 (TIM-3) does not contain inhibitory or death signaling motifs in its cytoplasmic domain, it has been proposed to be associated with T cell suppression and/or exhaustion. However, several lines of evidence suggest that TIM-3 can stimulate T cells as a costimulatory molecule by coupling Src family tyrosine kinase Fyn and the p85 phosphatidylinositol 3-kinase...
BACKGROUND Both the T cell immunoglobulin domain- and mucin domain-containing molecule-3 (Tim-3) and the death receptor Fas contribute to the pathogenesis of various autoimmune diseases, including systemic lupus erythematosus (SLE). The aim of the present study was to determine whether Tim-3 and Fas are co-expressed on certain peripheral T lymphocyte subsets, and whether this expression is asso...
Approximately 200 million people throughout the world are infected with hepatitis C virus (HCV). One of the most striking features of HCV infection is its high propensity to establish persistence (approximately 70-80%) and progressive liver injury. Galectins are evolutionarily conserved glycan-binding proteins with diverse roles in innate and adaptive immune responses. Here, we demonstrate that...
PROBLEM The T-cell immunoglobulin and mucin domain (TIM) family is a relatively newly described group of molecules with a conserved structure and important immunological functions. Identification of Galectin-9 as a ligand for TIM-3 has established the Galectin-9/TIM-3 pathway as an important negative regulator of Th1 immunity and tolerance induction. Data about the TIM-3/Gal-9 pathway in the pa...
AIMS/INTRODUCTION Type 2 diabetes is a worldwide disease that is associated with increased rates of obesity and reduced physical activity. Obesity-associated insulin resistance in type 2 diabetes is a disorder in the balance between pro-inflammatory and anti-inflammatory signals. T cell immunoglobulin and mucin domain-containing molecule 3 (Tim-3) has been reported as an important regulatory in...
Flaviviruses enter host cells by endocytosis initiated when the virus particles interact with cell surface receptors. The current model suggests that flaviviruses use at least two different sets of molecules for infectious entry: attachment factors that concentrate and/or recruit viruses on the cell surface and primary receptor(s) that bind to virions and direct them to the endocytic pathway. H...
Tim-3, a member of the novel Tim (T cell immunoglobulin and mucin domain) family, has been reported to negatively regulate the immune responses against viral infection and had implications for autoimmune disease. However, the nature and role of Tim-3(+) CD4 T cells in human tumors remain largely unknown. In the present study, we characterized Tim-3(+) CD4 T cells in 100 specimens from human hep...
Loss of CD4 T cell help correlates with virus persistence during acute hepatitis C virus (HCV) infection, but the underlying mechanism(s) remain unknown. We developed a combined proliferation/intracellular cytokine staining assay to monitor expansion of HCV-specific CD4 T cells and helper cytokines expression patterns during acute infections with different outcomes. We demonstrate that acute re...
