Molecular variations in Th1-specific cell surface gene Tim-3

Preparation and characterization of a novel nanobody against T-cell immunoglobulin and mucin-3 (TIM-3)

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-3 Directly Enhances CD8 T Cell

Tim-3+ T-bet+ tumor-specific Th1 cells colocalize with and inhibit development and growth of murine neoplasms.

Although T cells infiltrate many types of murine and human neoplasms, in many instances tumor-specific cytotoxicity is not observed. Strategies to stimulate CTL-mediated antitumor immunity have included in vitro stimulation and/or genetic engineering of T cells, followed by adoptive transfer into tumor-bearing hosts. In this model of B cell lymphoma in SJL/J mice, we used Tim-3(+) T-bet(+) Th1 ...

TIM-1 and TIM-3 enhancement of Th2 cytokine production by mast cells Short title: Role of TIM-1 and TIM-3 in mast cell function

Members of the T cell immunoglobulinand mucin-domain-containing molecule (TIM) family have roles in T cell-mediated immune responses. TIM-1 and TIM-2 are predominantly expressed on Th2 cells, whereas TIM-3 is preferentially expressed on Th1 and Th17 cells. We found that TIM-1 and TIM-3, but neither TIM-2 nor TIM-4, were constitutively expressed on mouse peritoneal mast cells and bone-marrow-der...

Impaired expression of Tim-3 on Th17 and Th1 cells in psoriasis.

Psoriasis is a chronic skin disease mediated by Th17 and/or Th1 cells. Tim-3 is a cell surface molecule preferentially expressed on Th17 and Th1 cells. The interaction of Tim-3 with Tim-3 ligand inhibits cytokine production. To assess whether T cells in psoriasis have functional abnormalities, expression of cell surface Tim-3 on blood T cells producing interleukin-17 (Th17/Tc17 cells) or interf...
