Toll-like receptor 4 and atherogenesis

open access: yesAnnals 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.

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

open access: yesNature 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 ...

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.

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

open access: yesEuropean 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

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

open access: yes, 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]

open access: yesMolecules, 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.

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

open access: yes, 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 ...

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

open access: yesRevista 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

Genetic association and expression studies indicate a role of toll-like receptor 8 in pulmonary tuberculosis. [PDF]

open access: yes, 2008
Despite high rates of exposure, only 5-10% of people infected with Mycobacterium tuberculosis will develop active tuberculosis (TB) disease, suggesting a significant role for genetic variation in the human immune response to this infection.

Extracellular nicotinate phosphoribosyltransferase binds Toll like receptor 4 and mediates inflammation

open access: yesNature 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-
