Sequence variants of toll like receptor 4 and late-onset Alzheimer's disease.

PLoS ONE, 2012
BackgroundToll like receptor 4 (TLR4) has been related to inflammation and beta-amyloid deposition in Alzheimer's disease (AD) brain. No study has explored the association between haplotype-tagging single nucleotide polymorphisms (htSNPs) of TLR4 and AD ...

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

, 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.

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

Bacterial flagellin is a dominant, stable innate immune activator in the gastrointestinal contents of mice and rats

Gut Microbes, 2023
Intestinal contents comprise the largest repository of immunogenic ligands of microbial origin. We undertook this study to assess the predominant microbe-associated molecular patterns (MAMPs) present therein and the receptors) that mediate the innate ...

Fibronectin III 13-14 Domains Induce Joint Damage via Toll-Like Receptor 4 Activation and Synergize with Interleukin-1 and Tumour Necrosis Factor [PDF]

, 2011
Cartilage loss is a feature of chronic arthritis. It results from degradation of the extracellular matrix which is composed predominantly of aggrecan and type II collagen.

Computational Approaches to Toll-Like Receptor 4 Modulation [PDF]

Molecules, 2016
Toll-like receptor 4 (TLR4), along with its accessory protein myeloid differentiation factor 2 (MD-2), builds a heterodimeric complex that specifically recognizes lipopolysaccharides (LPS), which are present on the cell wall of Gram-negative bacteria, activating the innate immune response.

Toll‐like receptor 4 polymorphisms in Saudi population with cardiovascular diseases

Molecular Genetics & Genomic Medicine, 2019
Background Toll‐like receptors play a substantial role in innate immunity and the effects of TLR4 genetic variants on cardiovascular diseases are still largely unknown.

TOLL-LIKE RECEPTORS (TLR) 2 AND 4 EXPRESSION OF KERATINOCYTES FROM PATIENTS WITH LOCALIZED AND DISSEMINATED DERMATOPHYTOSIS

Revista do Instituto de Medicina Tropical de São Paulo, 2015
There are few studies on the role of innate immune response in dermatophytosis. An investigation was conducted to define the involvement of Toll-Like Receptors (TLRs) 2 and 4 in localized (LD) and

Microglia-Secreted Galectin-3 Acts as a Toll-like Receptor 4 Ligand and Contributes to Microglial Activation. [PDF]

, 2015
Inflammatory response induced by microglia plays a critical role in the demise of neuronal populations in neuroinflammatory diseases. Although the role of toll-like receptor 4 (TLR4) in microglia's inflammatory response is fully acknowledged, little is ...

Extracellular nicotinate phosphoribosyltransferase binds Toll like receptor 4 and mediates inflammation

Nature Communications, 2019
The enzyme nicotinate phosphoribosyltransferase (NAPRT) mediates the rate-limiting step in NAD salvage pathway starting from nicotinic acid. Here the authors show that NAPRT can be detected extracellularly, binds to Toll like receptor 4, and activates NF-
