Profound thrombocytopenia occurs in humans with sepsis and in mice administered lipopolysaccharide (LPS). Growing evidence indicates that platelets may contribute to these abnormalities, but whether that is a direct result of LPS activation of platelets or an indirect result of other inflammatory mechanisms remains unclear. Here we demonstrate that although platelets do not increase P-selectin ...
Toll-like receptor 4 (TLR4) is key regulators of both innate and adaptive immune responses. TLR4 recognizes pathogen-associated molecular patterns (PAMPs) and activates the inflammatory cells. The function of TLR4 in atherosclerosis has been investigated in mouse knockout studies and epidemiological studies of human TLR4 polymorphisms. These studies have shown that TLR4 function affects the ini...
systemic lupus erythematosus (sle) is a chronic autoimmune disease which results in damage to various organs. some animal studies have revealed that activation of toll-like receptors (tlrs) is important in the pathogenesis of sle. in the present study, the percentage of different immune cell subsets in 35 sle patients and 38 control subjects was analyzed by flow cytometry. we also assessed the ...
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...
Background: Myocardial dysfunction is one of the major complications in patients with sepsis where there is a relationship between the blood level of cytokines and the onset of myocardial depression. In many cases of sepsis, the presence of Lipopolysaccharide (LPS) has been established. LPS Binding Protein (LBP) bound endotoxin is recognized by CD14/toll-like receptor-4 (TLR4) complexes in inna...
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...
An understanding of lipopolysaccharide (LPS) signal transduction is a key goal in the effort to provide a molecular basis for the lethal effect of LPS during septic shock and point the way to novel therapies. Rapid progress in this field during the last 6 years has resulted in the discovery of not only the receptor for LPS - Toll-like receptor 4 (TLR4) - but also in a better appreciation of the...
