There has been considerable interest in the effect of heat shock proteins (HSPs) on the innate immune system. Whether HSPs have any direct effects on the activation of lymphocytes is not clear. Using gene expression array, protein array and enzyme-linked immunosorbent assay, we demonstrated that highly purified recombinant murine Hsp60 (rmHsp60), essentially free of lipopolysaccharide contamination,...
The aim of the present study was to determine the age-related changes of phagocytic capacity and the kinetic production of cytokines in lipopolysaccharide-stimulated porcine alveolar macrophages. For this purpose, AMs were isolated from 5 (newborn), 40 (post-weaned) and 120 (young) day old pigs. Results of phagocytosis assay showed that AMs from newborn piglets had less phagocytic capacity than those...
Th17 cytokines IL-17A and IL-17F as pro-inflammatory cytokines played an important role in triggering inflammatory responses. However, little was known about the expression of IL-17A and IL-17F in acute lung injury (ALI). Therefore, the present study investigated the expression of IL-17A and IL-17F in lipopolysaccharide (LPS)-induced ALI in rats and rat pulmonary microvascular endothelial cells (PMVEC)...
The study was designed to characterize and compare chicken bone marrow and peripheral blood monocyte derived dendritic cells (chBM-DC and chMoDC) and to evaluate inflammatory cytokine and chemokine alterations in response upon LPS stimulation. Typical morphology was observed in DCs from 48h of culture using recombinant chicken GM-CSF and IL-4. Maturation of DCs with LPS (1μg/ml) showed significant...
The study objective was to determine the protective effects of thymoquinone (TQ) on brain tissues oxidative stress status, hippocampal cytokine level, and learning and memory deficits induced by lipopolysaccharide (LPS) in rats.Animals were randomly divided into the following groups and treated: (1) Control (saline), (2) LPS (1mg/kg i.p.), (3–5) 2, 5 or 10mg/kg TQ extract 30min before LPS injection...
