P-34: Expression of Toll-like Receptor2-3 Genes in Sertoli Cells of Patients with Azoospermia
Authors
Abstract:
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 evaluate the expression of TLR 2 and TLR3 in sertoli cells patient Azoospermia. Materials and Methods: Biopsies were obtained from 10 men who underwent TESE. All men taking part in this study had no history of infection and congenital disorders. Tissue samples were transferred to lectin coated Petri dishes after enzymatic dissociation and isolation. After few passages, all the cells were harvested and sorted by flowcytometery. Then, TLR gene expressions were determined by RT-PCR. Results: Isolation, purification and culture of the human sertoli cells were performed successfully. Also, it was shown that TLR 2 and TLR3 genes are expressed in these cells. In addition, it seems that TLR3 is expressed more than TLR2. Conclusion: This results showed that the expression of TLR genes in human sertoli cells specially TLR 2-3, could play an important role in developing immunity against pathogens as well as allo and auto-antigens in somniferous tubules.

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...
full textToll 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...

Background: Toll like receptors (TLRs) are well recognized players in inflammatory conditions. Among them TLR-4 is involved in chronic inflammatory processes such as formation of atherosclerotic plaques. Objective: The present study was aimed to examine the effects of percutanoeus coronary intervention (PCI) as a revascularization method on monocyte expression of hTLR-4 and on the serum levels ...
