The aim of the present study was to investigate the expression levels of the T-cell immunoglobulin and mucin domain-containing protein-3 (TIM-3) and galectin-9 proteins and their clinical value in esophageal squamous cell carcinoma (ESCC) in Chinese patients. The expression profiles of TIM-3 and galectin-9 in ESCC were determined by the immunohistochemical analysis of the postoperative patholog...

T cell immunoglobulin and mucin domain-containing protein 3 (Tim-3) is a newly identified negative immunomodulator that is up-regulated on dysfunctional T cells during viral infections. The expression and function of Tim-3 on human innate immune responses during HCV infection, however, remains poorly characterized. In this study, we report that Tim-3 is constitutively expressed on human resting...

The immunoregulatory protein T-cell immunoglobulin- and mucin-domain-containing molecule-3 (Tim-3) mediates T-cell exhaustion and contributes to the suppression of immune responses in both viral infections and tumors. Tim-3 blockade reverses the exhausted phenotype of CD4+ and CD8+ T cells in several chronic diseases, including melanoma. Interestingly, natural killer (NK) cells constitutively e...

The Period (PER), Timeless (TIM), and Double-Time (DBT) proteins are essential components of one feedback loop in the Drosophila circadian molecular clock. PER and TIM physically interact. Coexpression of PER and TIM promotes their nuclear accumulation and influences the activity of DBT: although DBT phosphorylates and destabilizes PER, this is suppressed by TIM. Experiments using Drosophila ce...

The timeless mutation (tim) leads to loss of circadian behavioral rhythms in Drosophila melanogaster. The effects of tim on rhythmicity involve interactions with period (per), a second essential clock gene, as the tim mutation suppresses circadian oscillations of per transcription and blocks nuclear localization of a PER reporter protein. In the present study it was found that the tim mutant co...
