چکیده

PURPOSE To investigate the role of Toll-like receptors (TLRs) 2, 3, 4, and 8 in the pathogenesis of Behcet's disease (BD). METHODS Sixteen patients with active ocular BD and 16 healthy volunteers were included in this study. Total RNA was isolated from PBMCs to determine mRNA levels of TLRs, including TLR2, TLR3, TLR4, and TLR8. Cell surface receptor activity of these TLRs was investigated by FACS analysis. Monocytes and naïve T cells from patients and controls were cultured with or without TLR ligands, such as LPS, PGN, R848, or PolyI:C. Culture supernatants were collected and IL-17, IL-1β, and IL-23 were analyzed by ELISA. RESULTS A markedly higher expression at the mRNA and protein level of TLR2, TLR3, TLR4, and TLR8 was observed in active BD patients as compared with controls. Significantly higher levels of IL-1β and IL-23 were detected in the supernatants of monocytes stimulated with LPS or PGN. A significantly higher level of IL-17 was observed in the supernatants of naïve T cells and monocytes stimulated with LPS or PGN in BD patients as compared with controls. Upon stimulation with R848 or PolyI:C, the levels of IL-17 in the supernatants of naïve T cells and monocytes and IL-23 levels in the supernatants of monocytes were not different between BD patients and controls. CONCLUSIONS A higher expression of TLRs may be involved in the pathogenesis of BD.

P-172: Intracellular Toll Like Receptors Expression in Endometriosis

Background: Endometriosis is a complex disease that profoundly affects the quality of life in many women. This disease affects roughly one in ten women of reproductive age. Endometriosis induces a variable amount of inflammatory reaction in pelvic environment. An active immune system needs to recognize these inflammatory agents. Rapid innate immune system defenses against infections involve the...

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...

Increased Expression of Toll-Like Receptors 2 and 4 in Renal Transplant Recipients that Develop Allograft Dysfunction: A Cohort Study

Background: The incidence of ischemic reperfusion injury (IRI) in early phase post-transplantation and activation of toll-like receptor (TLR-2) and TLR-4 remarkably impact the outcome of a renal allograft. Objective: To investigate whether the expression of TLRs in peripheral blood mononuclear cells (PBMCs) can predict the clinical outcome of kidney allografts. Methods: We obtained blood sample...

Simvastatin and Recombinant Antagonist of Receptors of Interleukin-1 Modulate Toll-like Receptors in Experimental Acute Ileitis in Rat

Background: The pathogenesis of inflammatory bowel disease is complex and multifactorial. Studies have led to the current concept that Toll-like receptors represent key mediators of innate host defense in the intestine, and they are involved in maintaining mucosal as well as commensal homeostasis. We studied the possibility of simvastatin and antagonist of receptors of interleukin-1 for pharmac...
