چکیده

BACKGROUND Toll-like receptors (TLR) recognize a variety of ligands, including pathogen-associated molecular patterns and link innate and adaptive immunity. Individual receptors can be up-regulated during infection and inflammation. We examined the expression of selected TLRs at the protein level in various types of renal disease. METHODS Frozen sections of renal biopsies were stained with monoclonal antibodies to TLR-2, -4 and -9. RESULTS Up-regulation of the three TLRs studied was seen, although the extent was modest. TLR-2- and -4-positive cells belonged to the population of infiltrating inflammatory cells; only in the case of TLR-9 were intrinsic glomerular cells positive in polyoma virus infection and haemolytic uraemic syndrome (HUS). CONCLUSIONS Evidence for the involvement of the three TLRs tested in a variety of human renal diseases was found. These findings add to our understanding of the role of the innate immune system in kidney disease.

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...

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...

Endoplasmic reticulum stress regulates inflammation in adipocyte of obese rats via toll-like receptors 4 signaling

Objective(s): To explore whether endoplasmic reticulum (ER) stress regulates inflammation in adipose tissue of obese rats via TLR4 signaling. Materials and Methods: Sprague Dawley rats were randomly divided into four groups, and body weight, food intake, and free fatty acids (FFA) were measured. Real-time PCR and Western blot were used to determine mRNA or protein expression of TLR4, TRAF6, IKK...

Activation of Toll-Like Receptors 2 by High-Mobility Group Box 1 in Monocytes from Patients with Ischemic Stroke

Background: Stroke is a leading cause of death all around the world, and ischemic stroke is considered to be the most common stroke type. Toll-like receptors (TLRs) are important molecules for detection of both pathogen invasion and tissue damage. In this regard, the purpose of this study was to assess the expression level of TLR2 on monocytes in patients with ischemic stroke and to evaluate th...
