Toll-like receptor 2 agonists inhibit human fibrocyte differentiation

Toll-like receptor 2 agonists inhibit human fibrocyte differentiation

BACKGROUND In healing wounds, some monocytes enter the wound and differentiate into fibroblast-like cells called fibrocytes. Since Toll-like receptors (TLRs) are present on monocytes, and pathogens that can infect a wound have and/or release TLR agonists, we examined whether TLR agonists affect fibrocyte differentiation. RESULTS When human peripheral blood mononuclear cells (PBMCs) were cultu...

P-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...

Toll-like receptor 2 agonists exacerbate accelerated nephrotoxic nephritis.

Glomerulonephritis can be exacerbated by infection. This study investigated the effect of N-palmitoyl-S-(2,3-bis(palmitoyloxy)-(2R,S)-propyl)-(R)-cysteinyl-seryl-(lysyl)3-lysine (Pam3CysSK4), a synthetic Toll-like receptor 2 (TLR2) ligand, that was given at immunization on disease severity in accelerated nephrotoxic nephritis. Stimulation of TLR by microbial constituents is known to influence t...

NaCl Potentiates Human Fibrocyte Differentiation

Excessive NaCl intake is associated with a variety of fibrosing diseases such as renal and cardiac fibrosis. This association has been attributed to increased blood pressure as the result of high NaCl intake. However, studies in patients with high NaCl intake and fibrosis reveal a connection between NaCl intake and fibrosis that is independent of blood pressure. We find that increasing the extr...
