The immune response plays an important role in staving off cancer; however, mechanisms of immunosuppression hinder productive anti-tumor immunity. T cell dysfunction or exhaustion in tumor-bearing hosts is one such mechanism. PD-1 has been identified as a marker of exhausted T cells in chronic disease states, and blockade of PD-1-PD-1L interactions has been shown to partially restore T cell fun...

Engulfment of apoptotic cells is an active process coordinated by receptors on phagocytes and ligands on apoptotic cells [1]. Phosphatidylserine (PtdSer) is a key ligand on apoptotic cells, and recently three PtdSer recognition receptors have been identified, namely, TIM-4, BAI1, and Stabilin-2 [1-6]. Whereas BAI1 is dependent on the ELMO1/Dock180/Rac signaling module, and Stablilin-2 appears t...

The monocyte chemotactic protein 3 (MCP-3) belongs to the MCP subgroup of the CC chemokines and promotes chemotaxis of immune cells. MCP-1 is believed to play an important role in monocyte infiltration into tumor tissues; however, the relationship between tumor-infiltrating macrophage/microglia (TIM/M) and the expression of chemokines has not been investigated in detail in human glioma samples;...

Ferritin binds specifically and saturably to a variety of cell types, and recently several ferritin receptors have been cloned. TIM-2 is a specific receptor for H ferritin (HFt) in the mouse. TIM-2 is a member of the T cell immunoglobulin and mucin domain containing (TIM) protein family and plays an important role in immunity. The expression of TIM-2 outside of the immune system indicates that ...

UNLABELLED Multiple host molecules are known to be involved in the cellular entry of filoviruses, including Ebola virus (EBOV); T-cell immunoglobulin and mucin domain 1 (TIM-1) and Niemann-Pick C1 (NPC1) have been identified as attachment and fusion receptors, respectively. However, the molecular mechanisms underlying the entry process have not been fully understood. We found that TIM-1 and NPC...

The immunoinhibitory receptor T cell immunoglobulin domain and mucin domain-3 (Tim-3) and its ligand, galectin-9 (Gal-9), are involved in the immune evasion mechanisms for several pathogens causing chronic infections. However, there is no report concerning the role of Tim-3 in diseases of domestic animals. In this study, cDNA encoding for bovine Tim-3 and Gal-9 were cloned and sequenced, and th...

Objective(s): 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 Meth...

TIM is a ray-tracing program that can model very general light-ray-direction changes, so general, in fact, that they can lead to physically impossible light-ray fields [1]. We wrote TIM as a tool for our research on windows that perform precisely those light-ray-direction changes. They can do this by compromising other aspects of the light field, but this compromise can be unnoticeably small. W...

INTRODUCTION T cell immunoglobulin and mucin domain-2 (TIM-2) has been shown to regulate CD4 T cell activation. However, the role of TIM-2 in the autoimmune disease models has not been clarified yet. In this study, we investigated the effects of anti-TIM-2 monoclonal antibodies (mAbs) in collagen-induced arthritis (CIA) to determine whether TIM-2 contributes to the development of T helper (Th) ...
