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...


 Purpose: To investigate the action of miR-483-3p in pediatric pneumonia and identify potential biomarkers.
 Methods: Bronchoalveolar lavage was collected from 38 patients 25 healthy children. The expression determined using qRT-PCR. Alveolar macrophages children were cultured used for functional assays. Transwell assay conducted to evaluate macrophage cell migration. Cell viability ...

Objective(s): We aimed to investigate the influence of transient receptor potential channel 3 (TRPC3) on lipopolysaccharide-induced (LPS) preterm delivery mice. Materials and Methods: Mice were randomly assigned to the four groups: an unpregnant group, a mid-pregnancy group (E15), a term delivery group, and an LPS-induced preterm delivery group (intraperitoneal injection LPS at 15 days). Uterin...

the aim of this study was to examine the anti-inflammatory effects of co-administration of growthhormone-releasing peptide-2 (ghrp-2) and growth hormone (gh) on tumor necrosis factor-α (tnf-α),interleukin-6 (il-6) and inducible nitric oxide synthase (inos) gene expression induced by lps in the mousebrain. thirty-five male nmri mice (25±5 g) were injected through the mouse tail vein with saline,...

Purpose: To investigate the role of nicotinamide phosphoribosyltransferase (NAMPT) in lipopolysaccharide (LPS)-induced damage trophoblastic HTR-8/SVneo cells (HTR8 cells), with aim ultimately providing new therapeutic targets preeclampsia (PE).Methods: Trophoblastic was cultured and treated LPS to mimic PE vitro, while FK866, an antagonist NAMPT, used establish inflammatory model HTR8 cells. We...

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...

We prospectively studied 156 patients with a diagnosis of community-acquired pneumonia requiring admission. Several respiratory specimens were obtained for the detection of Chlamydia pneumoniae by cell culture and PCR. Three serum samples were obtained from each patient. Serological diagnosis of a C. pneumoniae infection was determined by the microimmunofluorescence (MIF) test, the complement f...

signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...

Abstract Background and Aims Cellular fatty acid metabolism was supposed to be tightly associated with immune responses. Pyroptosis is a form of programmed cell death dependent on the NLRP3 inflammasome activation. Previous studies have revealed that acyl-CoA synthetase 2 (ACSS2) promoted synthesis under metabolic stress. However, whether ACSS2-mediated can regulate pyroptosis inflammatory resp...
