TLR4 recruits TRIF-related adaptor molecule (TRAM, also known as TICAM2) as a sorting adaptor to facilitate the interaction between TLR4 and TRIF and then initiate TRIF-dependent IRF3 activation. However, the mechanisms by which TRAM links downstream molecules are not fully elucidated. In this study, we show that TRAM undergoes tyrosine phosphorylation upon TLR4 activation and that is required ...
TLR4 is the receptor for the Gram-negative bacterial cell wall component LPS. TLR4 signaling is controlled by both positive and negative regulators to balance optimal immune response and potential sepsis. Unchecked TLR4 activation might result in autoimmune diseases, a hypothesis that has not been formally resolved. In this study, we found that TLR4 signaling to LPS can be positively enforced b...
The role of toll-like receptors (TLRs) has been described in the pathogenesis of renal ischemia/reperfusion injury, but data on the expression and function of TLR4 during renal allograft damage are still scarce. We analyzed the expression of TLR4 in an experimental rat model 6 and 28 days after allogeneic kidney transplantation in comparison to control rats and rats after syngeneic transplantat...
TLR4 is an innate immune receptor with expression in human skin, keratinocytes as well as squamous cell carcinoma (SCC) of the skin. In the present study we investigate the role of TLR4 as a negative regulator of keratinocyte proliferation. We present here that the expression of TLR4 increased with the differentiation of cultured keratinocytes in a passage-dependent manner or under calcium-rich...
Mesenchymal stem cells (MSCs) from adult bone marrow maintain their self-renewal ability and the ability to differentiate into osteoblast. Thus, adult bone marrow MSCs play a key role in the regeneration of bone tissue. Previous studies indicated that TLR4 is expressed in MSCs and is critical in regulating the fate decision of MSCs. However, the exact functional role and underlying mechanisms o...
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...
