Interaction of Opioids with TLR4—Mechanisms and Ramifications [PDF]

open access: yesCancers, 2021
The innate immune receptor toll-like receptor 4 (TLR4) is known as a sensor for the gram-negative bacterial cell wall component lipopolysaccharide (LPS). TLR4 activation leads to a strong pro-inflammatory response in macrophages; however, it is also recognised to play a key role in cancer.

Echinacea purpurea extract (cichoric acid) exerts an anti-inflammatory effect on yak PBMCs and regulates the TLR4 signalling pathway

open access: yesJournal of Veterinary Research, 2021
Inflammation is one of the main causes of impaired health in livestock and some of its processes weaken animal productivity and impact human health. The present study was conducted to evaluate the effect of echinacea extract (cichoric acid – CA) on yak ...

Targeting danger molecules in tendinopathy: the HMGB1/TLR4 axis [PDF]

open access: yes, 2017
Objectives: To seek evidence of the danger molecule, high-mobility group protein B1 (HMGB1) expression in human tendinopathy and thereafter, to explore mechanisms where HMGB1 may regulate inflammatory mediators and matrix regulation in human tendinopathy.

Lipopolysaccharide Recognition in the Crossroads of TLR4 and Caspase-4/11 Mediated Inflammatory Pathways

open access: yesFrontiers in Immunology, 2020
The innate immune response to lipopolysaccharide is essential for host defense against Gram-negative bacteria. In response to bacterial infection, the TLR4/MD-2 complex that is expressed on the surface of macrophages, monocytes, dendritic, and epithelial

Vaccinia virus protein A46R targets multiple Toll-like-interleukin-1 receptor adaptors and contributes to virulence [PDF]

open access: yes, 2005
Viral immune evasion strategies target key aspects of the host antiviral response. Recently, it has been recognized that Toll-like receptors (TLRs) have a role in innate defense against viruses.

TLR4 and HMGB1: partners in crime? [PDF]

open access: yesKidney International, 2011
Chen et al. confirmed the role of Toll-like receptor 4 (TLR4) in ischemic kidney injury using mice harboring spontaneous disabling mutations of the receptor and generated chimeras between TLR4-/- and TLR4+/+ mice. The major findings demonstrate the necessity of TLR4 in leukocytes, as well as in epithelial and endothelial cells, for the full-blown ...

TLR4 rs1927914 polymorphism contributes to serum TLR4 levels in patients with aortic aneurysm

open access: yesExperimental and Molecular Pathology, 2021
Toll-like receptor 4 (TLR4) is a crucial regulator of inflammatory reactions and vascular remodeling. Elevated TLR4 expression has been proved to be correlated with an increased risk of aortic aneurysm (AA). This study aimed to explore the influence of TLR4 gene polymorphisms on TLR4 expression levels and its probable functional significance in AA ...
