Toll-Like Receptor 4 Wild Type Homozygozity of Polymorphisms +896 and +1196 Is Associated with High Gastrin Serum Levels and Peptic Ulcer Risk. [PDF]

PLoS ONE, 2015
Toll-like receptor 4 is a part of the innate immune system and recognizes Helicobacter pylori lipopolysaccharide. The goal of this study was to analyze the role of Toll-like receptor 4 polymorphisms +896 (rs4986790) and +1196 (rs4986791) in the ...

Toll-like Receptor 4 Polymorphisms and Atherogenesis

New England Journal of Medicine, 2002
The ability to mount a prominent inflammatory response to bacterial pathogens confers an advantage in innate immune defense but may signal an increased risk of atherosclerosis. We determined whether recently discovered genetic variants of toll-like receptor 4 (TLR4) that confer differences in the inflammatory response elicited by bacterial ...

Toll‐like receptor 4 in CNS pathologies [PDF]

Journal of Neurochemistry, 2010
J. Neurochem. (2010) 114, 13–27.AbstractThe responses of the brain to infection, ischemia and trauma share remarkable similarities. These and other conditions of the CNS coordinate an innate immune response marked by activation of microglia, the macrophage‐like cells of the nervous system. An important contributor to microglial activation is toll‐like

Negative regulation of Toll-like receptor 4 signaling by the Toll-like receptor homolog RP105 [PDF]

Nature Immunology, 2005
Activation of Toll-like receptor (TLR) signaling by microbial signatures is critical to the induction of immune responses. Such responses demand tight regulation. RP105 is a TLR homolog thought to be mostly B cell specific, lacking a signaling domain. We report here that RP105 expression was wide, directly mirroring that of TLR4 on antigen-presenting ...

Could an endoneurial endothelial crosstalk between Wnt/β-catenin and Sonic Hedgehog pathways underlie the early disruption of the infra-orbital blood-nerve barrier following chronic constriction injury? [PDF]

, 2017
BackgroundBlood–nerve barrier disruption is pivotal in the development of neuroinflammation, peripheral sensitization, and neuropathic pain after peripheral nerve injury.

Toll-like receptor 4 and atherogenesis

Annals of Medicine, 2003
Toll-like receptor 4 (TLR4) is a pattern recognition receptor involved in the innate immune response to various microorganisms and other exogenous and endogenous stress factors. Recently, evidence emerged that important inflammatory processes implicit in human atherogenesis are mediated in part via the TLR4/nuclear factor-kappaB pathway.

Lipopolysaccharide and toll-like receptor 4 in dogs with congenital portosystemic shunts [PDF]

, 2015
Surgical attenuation of a congenital portosystemic shunt (CPSS) results in increased portal vein perfusion, liver growth and clinical improvement. Portal lipopolysaccharide (LPS) is implicated in liver regeneration via toll-like receptor (TLR) 4 mediated

Toll-like receptor 1 inhibits Toll-like receptor 4 signaling in endothelial cells [PDF]

European Journal of Immunology, 2002
Toll-like receptor 4 (TLR4) is the signal-transducing component of the LPS recognition complex and is essential for LPS-induced septic shock. Here we demonstrate that TLR1 has the capacity to abrogate TLR4 signaling. Human microvascular endothelial cells express TLR4 but not TLR1 and respond to LPS through TLR4. The ability of these cells to respond to

Lipopolysaccharide as trigger of platelet aggregation via eicosanoid over-production [PDF]

, 2017
The effect of lipopolysaccharide (LPS) on platelet aggregation is still controversial. We performed in vitro and ex vivo studies in controls and in patients with community-acquired pneumonia (CAP) to assess the effect of LPS on platelet activation (PA ...
