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: 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...

background: during recent years, infection of acinetobacter baumanii showed a rapid growth in hospitals and community. toll-like receptors (tlrs) are the most important pattern recognition receptors, which play a critical role during recognizing invading pathogens by the natural immune system. our objective was to determine the associations of tlrs polymorphisms with the susceptibility to a. ba...

Objective(s): TLR-4 activates a number of inflammatory signaling pathways. Also, AMPK could be involved in anti-inflammatory signaling. The aim of this study was to identify whether stimulation of AMPK could inhibit LPS-induced Tlr-4 gene expression in mice hearts. Materials and methods: Heart AMPK activity and/or Tlr-4 expression was stimulated in different mice groups, using respectively IP i...

objective(s): tlr-4 activates a number of inflammatory signaling pathways. also, ampk could be involved in anti-inflammatory signaling. the aim of this study was to identify whether stimulation of ampk could inhibit lps-induced tlr-4 gene expression in mice hearts. materials and methods: heart ampk activity and/or tlr-4 expression was stimulated in different mice groups, using respectively ip i...

Here, we have investigated the mRNA expression of Toll-like receptor 2 (TLR-2), TLR-4, and MD-2 in spleens and livers of C3H/HeN mice (carrying wild-type TLR-4) and C3H/HeJ mice (carrying mutated TLR-4) in response to Salmonella infection. During Salmonella infections, TLR-4 is activated, leading to increased TLR-2 and decreased TLR-4 expression.

It is known that Toll-like receptor (TLR)-4 plays an important role in myocardial infarction and atherothrombosis. The role of TLR-4 in arterial thrombosis is undefined. Both TLR-4-deficient (TLR-4(-/-)) and wild-type (WT) mice were subjected to FeCl3 carotid artery injury, and the time required to form an occlusive thrombus was measured. The mean time to occlusion in TLR-4(-/-) mice was signif...

PURPOSE To investigate the function and expression of Toll-like receptors (TLR) in bone marrow cells of myelodysplastic syndrome (MDS) patients and to examine their involvement in the apoptotic phenomenon characterizing MDS hematopoiesis. EXPERIMENTAL DESIGN TLR mRNA and protein expression was investigated in bone marrow cell populations of MDS patients and controls. TLR-4 ability to recogniz...
