Dysfunction of the virus-specific T cells is a cardinal feature in chronic persistent viral infections such as one caused by hepatitis C virus (HCV). In chronic HCV infection, virus-specific dysfunctional CD8 T cells often overexpress various inhibitory receptors. Programmed cell death 1 (PD-1) was the first among these inhibitory receptors that were identified to be overexpressed in functional...

Lichen planus (LP) and discoid lupus erythematosus (DLE) are chronic, inflammatory autoimmune skin diseases with interface dermatitis significant morbidity whose pathogenesis is incompletely understood. Recently, NanoString Technologies has developed GeoMx® digital spatial profiling (DSP), a novel highly multiplex method for detection of proteins RNA in fixed tissues. Here, we perform proteomic...

New insights into the control of T-cell activation and proliferation have led to the identification of checkpoint proteins that either up- or downmodulate T-cell reactivity. Monoclonal antibody immunotherapies that are reactive with cytotoxic T lymphocyte antigen 4 or programmed death receptor 1 have shown promising therapeutic outcomes in mice and humans with established cancer, highlighting t...

T-cell immunoglobulin and mucin-domain-containing molecule 3 (Tim-3) has complicated roles in regulating monocytes and macrophages in various diseases and it tends to be an inhibitory molecule to facilitate the immune escape of parasites in malaria. However, the mechanisms of Tim-3 mediated responses in monocytes and macrophages in malaria have not been clear. In this study, we found that Plasm...

Accumulated studies have demonstrated the important role of T cell immunoglobulin- and mucin-domain-containing molecule-3 (TIM-3) in various solid tumors and indicated its correlation with patients' survival. To further verify the prognostic significance of TIM-3 in cancer patients and its correlation with tumor, we performed this meta-analysis including seven studies searched from PubMed, Web ...

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...
