T cell immunoglobulin and mucin protein-3 (Tim-3)/Galectin-9 interaction regulates influenza A virus-specific humoral and CD8 T-cell responses.
Reactions to pathogens are usually tuned to effect immunity and limit tissue damage. Several host counterinflammatory mechanisms inhibit tissue damage but these may also act to constrain the effectiveness of immunity to acute infections, as we demonstrate in mice acutely infected with influenza A virus (IAV). We show that compared with wild type (WT), galectin-9 knockout (G9KO) mice mounted a m...
متن کاملPreparation 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...
متن کاملGalectin-9/TIM-3 Interaction Regulates Virus-Specific Primary and Memory CD8+ T Cell Response
In this communication, we demonstrate that galectin (Gal)-9 acts to constrain CD8(+) T cell immunity to Herpes Simplex Virus (HSV) infection. In support of this, we show that animals unable to produce Gal-9, because of gene knockout, develop acute and memory responses to HSV that are of greater magnitude and better quality than those that occur in normal infected animals. Interestingly, infusio...

متن کاملStimulation of Camel Polyclonal Antibody against Human T cell Immunoglobulin and Mucin 3
Background: T cell Immunoglobulin, Mucin (TIM)-3, is a type I transmembrane glycoprotein belonging to TIM family. This receptor expresses on T helper type 1 (Th1) cells that binds to galectin-9 (Gal9); inducing an inhibitory signal. As a result, apoptosis of Th1 cells occurs and cytotoxicity of CD8 T cells becomes evident in vitro. Therefore, this immunomodulatory molecule may ...
