T cell immunoglobulin and mucin domain (Tim)-3 is a molecule expressed on terminally differentiated murine Th1 cells but not on Th2 cells. Identification of Galectin-9 as a ligand for Tim-3 has now firmly established the Tim-3-Galectin-9 pathway as an important regulator of Th1 immunity, which results in apoptosis of Th1 cells. Here, we demonstrate that engagement of Tim-3 by mouse recombinant ...

The transmembrane protein Tim-3 has been shown to negatively regulate T-cell-dependent immune responses and was recently demonstrated to be associated with the phenomenon of immune exhaustion, which can occur as a consequence of chronic viral infection. Unlike other negative regulators of T-cell function (e.g., PD-1), Tim-3 does not contain any obvious inhibitory signaling motifs. We have found...

The T cell immunoglobulin and mucin domain 3 (Tim-3) is a plasma membrane-associated receptor which is involved in a variety of biological responses in human immune cells. It is highly expressed in most acute myeloid leukaemia (AML) cells and therefore may serve as a possible target for AML therapy. However, its biochemical activities in primary human AML cells remain unclear. We therefore anal...

INTRODUCTION Galectin-9 (Gal-9) induces adhesion and aggregation of certain cell types and inhibits the metastasis of tumor cells. T-cell immunoglobulin-and mucin domain-3-containing molecule 3 (TIM-3) plays a pivotal role in immune regulation. The aim of this study is to investigate Gal-9 and TIM-3 alterations in gastric cancer and their prognostic values. METHODS Gal-9 and Tim-3 expression ...

Natural killer (NK) cells are innate lymphocytes that play an important role against viral infections and cancer. This effect is achieved through a complex mosaic of inhibitory and activating receptors expressed by NK cells that ultimately determine the magnitude of the NK-cell response. The T-cell immunoglobulin- and mucin domain-containing (Tim)-3 receptor was initially identified as a T-help...

OBJECTIVE Infective endocarditis is usually caused by Streptococcus sanguinis and characterized by inflammatory responses in the endocardium. This study aimed to investigate if the new compound (3R)-5,6,7-trihydroxy-3-isopropyl-3-methylisochroman-1-one (TIM) isolated from Alpinia katsumadai Hayata could provide protection against lipoteichoic acid (LTA)-induced cell damage in embryonic rat hear...

The T-cell immunoglobulin and mucin domain (TIM) family is associated with autoimmune diseases, but its expression level in the immune cells of systemic lupus erythematosus (SLE) patients is not known. The aim of this study was to investigate whether the expression of TIM-3 mRNA is associated with pathogenesis of SLE. Quantitative real-time reverse transcription-polymerase chain reaction analys...

PD-1, TIM-3, and LAG-3 are molecules shown to have immune modulatory properties, and although initially classified as indicators of T cell hyporesponsiveness, it has become clear that they are also associated with the normal course of T cell activation. Functional studies have focused mainly on CD8(+) T cells during chronic inflammation due to interest in co-opting the cellular immune response ...

Kidney injury molecule-1/T cell IgG and mucin containing 1 (KIM-1/TIM-1) is a type 1 membrane receptor [1] which we identified as the most upregulated proximal tubular cell (PTC) protein following a variety of kidney injuries in animal models and human diseases [1] (Figure 1A). While KIM-1 (also known as hepatitis A virus cellular receptor-1 (HAVCR-1)) quickly was recognized as a promising biom...
