Description
TIM-3, also known as HAVCR2(epatitis A virus cellular receptor 2), belongs to TIM family cell surface receptor proteins.TIM-3 is up?regulated on several populations of activated myeloid cells and T cells. It is an immune checkpoint and together with other inhibitory receptors including PD-1and LAG3 mediate the CD8+ T-cell exhaustion. Also, it is primarily activated by galectin-9. The engagement leads to stimulation of an influx of calcium to intracellular space and induction of programmed cell death, apoptosis. As a consequence, a suppression of Th1 and Th17 responses and induction of immune tolerance occurs. Recombinant mouse TIM-3, fused to hIgG-His-tag at C-terminus, was expressed in HEK293 cell and purified by using conventional chromatography techniques
