Toll-like receptor 4 ligand can differentially modulate the release of cytokines by human platelets.
Blood platelets link the processes of haemostasis and inflammation. This study examined the immunomodulatory factors released by platelets after Toll-Like Receptor 4 (TLR4) engagement on their surfaces. Monoclonal anti-human FcgammaRII Ab (IV.3)-treated human platelets were cultured with TLR4 ligands in the presence or absence of blocking monoclonal antibody to human TLR4. The release of sCD62p...
Toll-like receptor 4 (TLR4) initiates both myeloid differentiation factor 88 (MyD88)-dependent and Toll/interleukin (IL)-1R domain-containing adapter, inducing interferon (IFN)-beta-dependent signaling, leading to production of proinflammatory mediators and type I interferon (IFN) to eliminate pathogens. However, uncontrolled TLR4 activation may contribute to pathogenesis of autoimmune and infl...
Opioid-induced proinflammatory glial activation modulates wide-ranging aspects of opioid pharmacology including: opposition of acute and chronic opioid analgesia, opioid analgesic tolerance, opioid-induced hyperalgesia, development of opioid dependence, opioid reward, and opioid respiratory depression. However, the mechanism(s) contributing to opioid-induced proinflammatory actions remains unre...
The aim of present study was to evaluate whether diets supplemented with dihydroartemisinin (DHA) could alleviate intestinal inflammatory injury in weaned piglets intrauterine growth retardation (IUGR). Twelve normal birth weight (NBW) and 12 IUGR were fed a basal diet (NBW-CON IUCR-CON groups), another the DHA at 80 mg/kg (IUGR-DHA group) from 21 49 d age. At age, 8 similar body each group sac...
Abstract The fibrinogen protein is composed of three subunits encoded for by the genes Fga, Fgb, and Fgg. This trimer a main component blood clots. Irregular clotting contributes to low pressure during septic shock, which eventually leads death from total system organ failure. A previously published data set finds Fgg be dysregulated sepsis in serum both wildtype (WT) toll-like receptor 4 (TLR4...
Toll-like receptor 4 (TLR4) recognizes specific structural motifs associated with microbial pathogens and also responds to certain endogenous host molecules associated with tissue damage. In Duchenne muscular dystrophy (DMD), inflammation plays an important role in determining the ultimate fate of dystrophic muscle fibers. In this study, we used TLR4-deficient dystrophic mdx mice to assess the ...
Toll-like receptor 4 (TLR4) mediates the response to lipopolysaccharide, and its activation induces the expression of a large number of inflammatory genes, many of which are also induced by other pathogen-associated molecular patterns. Interestingly, the subset of genes that are dependent on TLR4 for optimal expression during gram-negative bacterial infection has not been determined. We have pr...
Endogenous damage-associated molecular pattern (DAMP) molecules are released from cells during traumatic injury, allowing them to interact with pattern recognition receptors such as the toll-like receptors (TLRs) on other cells and subsequently, to stimulate inflammatory signaling. TLR4, in particular, plays a key role in systemic and remote organ responses to hemorrhagic shock (HS) and periphe...
Flavolipin, an amino acid-containing lipid isolated from Flavobacterium meningosepticum, induces many immune responses. It has been shown that flavolipin does not induce an immune response of macrophages derived from C3H/HeJ mice, which possess a point mutation in Toll-like receptor 4 (TLR4). To determine whether TLR4 or the molecular complex of TLR4 and TLR4 association molecule MD-2 mediates ...
We have studied the role of TLR4 in murine defenses against Candida albicans in two TLR4-defective mouse strains: C3H/HeJ mice which have defective TLR4 signaling, and TLR4-/- knockout mice. Both TLR4-defective mice strains experimentally infected with virulent C. albicans cells showed no significant difference in survival as compared with their respective controls. Recruitment of neutrophils t...
