Regulation of toll-like receptor 2 expression by macrophages following Mycobacterium avium infection.
Recent studies have implicated Toll-like receptors (TLR), especially TLR2 and TLR4, as sentinel receptors that signal the interaction of macrophages with bacterial pathogens via a NF-kappaB-mediated pathway. The regulation of TLR gene expression, however, has not been intensively studied. Here, we report that TLR2 mRNA was induced following infection of murine macrophages with Mycobacterium avi...
متن کاملToll Like Receptor 2 and 4 Expression in Peripheral Blood Mononuclear Cells of Multiple Sclerosis Patients
Background: Multiple sclerosis (MS) is a T cell mediated autoimmune disease with unknown etiology. Appropriate MS therapeutic strategies need thorough understanding of both disease etiology and pathogenesis mechanisms. Ligation of TLR-2 and TLR-4 stimulates the production of several cytokines leading to CNS autoimmunity and neurodegenerative diseases. Objective: To find a relationship between M...
متن کاملP-33: Expression of Toll-Like Receptor 2-3 Genes in Human Sertoli Cells
Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...
متن کاملRegulation of Toll-like receptor-2 expression by the Gal-lectin of Entamoeba histolytica.
The Gal/GalNAc lectin (Gal-lectin) of Entamoeba histolytica is a surface molecule involved in parasite adherence to host cells and is the most promising subunit vaccine candidate against amoebiasis. As macrophages are the major effector cells in host defense against amoebas, we studied the molecular mechanisms by which Gal-lectin activates macrophage. Microarray analysis showed that Gal-lectin ...
متن کاملToll-like receptor 3 ligand attenuates LPS-induced liver injury by down-regulation of toll-like receptor 4 expression on macrophages.
This study demonstrates that pretreatment with polyinosinic-polycytidylic acid (poly I:C) significantly decreased the mortality and liver injury caused by injection of lipopolysaccharide (LPS) in the presence of d-galactosamine (d-GalN) in C57BL/6 mice. Depletion of natural killer, natural killer T, and T cells did not change the protective effect of poly I:C on LPS/d-GalN-induced liver injury ...
