Toll-Like Receptor 4 Signaling is Involved in IgA-Stimulated Mesangial Cell Activation

PURPOSE Deposition of polymeric IgA1 in the kidney mesangium is the hallmark of IgA nephropathy, but the molecular mechanisms of IgA-mediated mesangial responses and inflammatory injuries remain poorly understood. We hypothesize that Toll-like receptor 4 (TLR4) is involved in IgA-induced mesangial cell activation. MATERIALS AND METHODS Mouse mesangial cells were stimulated with lipopolysaccha...

O-34: Cell Membrane Toll like Receptors Expression in Follicular Cells of Women with Endometriosis

Background: Endometriosis is the growth of endometrial cells outside the uterine cavity. It has been suggested that immune system plays important roles in both initiation and progression of the disease. Several studies have been shown that women with endometriosis diverge in their expression of different genes including heat-shock proteins, fibronectin, and neutrophil elastase, which might be i...

Up-regulation of TLR2 and TLR4 in high mobility group Box1-stimulated macrophages in pulpitis patients

Objective(s): High Mobility Group Box1 (HMGB1) is a nonhistone, DNA-binding protein that serves a crucial role in regulating gene transcription and is involved in a variety of proinflammatory, extracellular activities. The aim of this study was to explore whether HMGB1 stimulation can up-regulate the expression of Toll-like Receptor 2 (TLR2) and Toll-like Receptor 4 (TLR4) on macrophages from p...
