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...

Background: The innate immune system is our first line of defense against invading pathogens. Toll–like receptors (TLRs) have been identified as a key role in mediating the function of innate immune system which bridges the gap between innate and adaptive immunity. For example, TLR2 is able to act as a homodimer to recognize lipoteichoic acids of Gram-positive bacteria but as a heterodimer with...

The innate immune system plays an important role in cerebral health and disease. In recent years the role of innate immune regulation by toll-like receptors in the brain has been highlighted. In this paper the expression of toll-like receptors and endogenous toll-like receptor ligands in the brain and their role in cerebral ischemia will be discussed. Further, the ability of systemic toll-like ...

Toll-like receptors are the important pattern recognition receptors of innate immune system, which mediate the immunological defence response against pathogen or endogenous damage associated molecules. Recently, more and more researches indicated that Toll-like receptor 2 played vital roles in the pathophysiology of many cardiovascular diseases, including atherosclerosis, coronary diseases, car...

INTRODUCTION AND AIMS Toll-like receptor 4 and proinflammatory cytokines play a central role in the progression of nonalcoholic fatty liver disease. We investigated IL-1, IL-6 and TNFα production and toll-like receptor 4 in both--obese and lean patients with non-alcoholic fatty liver disease who met different sets of metabolic syndrome criteria and linked the results with the disease burden. ...

BACKGROUND Aspergillus fumigatus causes invasive aspergillosis, a potentially fatal infection in oncohematological patients. Innate immune detection of A. fumigatus involves Toll-like receptor (TLR) 4 and TLR2, which forms a heterodimer with either TLR1 or TLR6. The role of those coreceptors in Aspergillus sensing is unknown. METHODS Cytokine production was measured in bone marrow-derived mac...
