OBJECTIVES As T-cell immunoglobulin and mucin domain 3 (TIM-3) is an immune regulatory molecule; its blocking or stimulating could alter the pattern of immune response towards a desired condition. Based on the unique features of nanobodies, we aimed to construct an anti-TIM-3 nanobody as an appropriate tool for manipulating immune responses for future therapeutic purposes. MATERIALS AND METHO...

Engulfment of apoptotic cells is predominantly executed by phagocytes via the recognition of "eat me" signals like phosphatidylserine (PS). Various PS-specific receptors exist on phagocytes, including Tyro3, Axl, and MerTK receptor tyrosine kinases (TAMs), T-cell immunoglobulin and mucin domain containing 1 and 4 (TIM1/4), and the newly identified CD300 family. The aim of the present auto-comme...

The T cell immunoglobulin- and mucin domain-containing molecules (Tim) have been implicated in the pathogenesis of immune diseases. In this study, we used quantitative real time reverse transcription polymerase chain reaction to examine the Tim 1 mRNA expression in peripheral blood mononuclear cells from Henoch Schonlein purpura patients. The results showed that Tim1 mRNA expression was signifi...

T-cell immune responses modulated by T-cell immunoglobulin and mucin domain-containing molecule 3 (Tim-3) during Mycobacterium tuberculosis (Mtb) infection in humans remain poorly understood. Here, we found that active TB patients exhibited increases in numbers of Tim-3-expressing CD4(+) and CD8(+) T cells, which preferentially displayed polarized effector memory phenotypes. Consistent with eff...
