Toll-like receptor 4 (TLR4): new insight immune and aging

open access: yesImmunity & Ageing, 2023
TLR4, a transmembrane receptor, plays a central role in the innate immune response. TLR4 not only engages with exogenous ligands at the cellular membrane’s surface but also interacts with intracellular ligands, initiating intricate intracellular ...

COVID-19 and Toll-Like Receptor 4 (TLR4): SARS-CoV-2 May Bind and Activate TLR4 to Increase ACE2 Expression, Facilitating Entry and Causing Hyperinflammation

open access: yesMediators of Inflammation, 2021
Causes of mortality from COVID‐19 include respiratory failure, heart failure, and sepsis/multiorgan failure. TLR4 is an innate immune receptor on the cell surface that recognizes pathogen‐associated molecular patterns (PAMPs) including viral proteins and

TLR4 regulates RORγt+ regulatory T-cell responses and susceptibility to colon inflammation through interaction with Akkermansia muciniphila

open access: yesMicrobiome, 2022
Background Well-balanced interactions between gut microbiota and the immune system are essential to prevent chronic intestinal inflammation, as observed in inflammatory bowel diseases (IBD). Toll-like receptor 4 (TLR4) functions as a sensor mediating the

TLR4 signalling via Piezo1 engages and enhances the macrophage mediated host response during bacterial infection

open access: yesNature Communications, 2021
TLR4 signaling plays key roles in the innate immune response to microbial infection. Innate immune cells encounter different mechanical cues in both health and disease to adapt their behaviors.

Pharmacological Effects of Polyphenol Phytochemicals on the Intestinal Inflammation via Targeting TLR4/NF-κB Signaling Pathway

open access: yesInternational Journal of Molecular Sciences, 2022
TLR4/NF-κB is a key inflammatory signaling transduction pathway, closely involved in cell differentiation, proliferation, apoptosis, and pro-inflammatory response.

Ursolic acid induces the production of IL6 and chemokines in both adipocytes and adipose tissue

open access: yesAdipocyte, 2020
Adipose tissue inflammation plays an important role in the regulation of glucose and lipids metabolism. It is unknown whether Ursolic acid (UA) could regulate adipose tissue inflammation, though it can regulate inflammation in many other tissues. In this

Endothelial toll-like receptor 4 maintains lung integrity via epigenetic suppression of p16INK4a. [PDF]

open access: yes, 2019
We previously reported that the canonical innate immune receptor toll-like receptor 4 (TLR4) is critical in maintaining lung integrity. However, the molecular mechanisms via which TLR4 mediates its effect remained unclear.

The Defensive Action of LYRM03 on LPS-Induced Acute Lung Injury by NF-κB/TLR4/NLRP3 Signals

open access: yesJournal of Investigative Surgery, 2021
The aim of the current investigation was to study the role of 3-amino-2-hydroxy-4-phenyl-valyl-isoleucine (LYRM03) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) and investigate its potential pathogenesis.

Paroxetine effect on expression of TLR2 and TLR4 genes in PBMCs of mentally normal individuals [PDF]

open access: yesمجله پزشکی دانشگاه علوم پزشکی تبریز, 2021
Background: Paroxetine is one of the well-known antidepressants. Recent studies have focused on paroxetine’s probable immuno-modulatory effects, since findings have indicated inflammation’s role in the pathophysiology of depression.

TLR4/MyD88/PI3K interactions regulate TLR4 signaling

open access: yesJournal of Leukocyte Biology, 2009
AbstractTLRs activate immune responses by sensing microbial structures such as bacterial LPS, viral RNA, and endogenous “danger” molecules released by damaged host cells. MyD88 is an adapter protein that mediates signal transduction for most TLRs and leads to activation of NF-κB and MAPKs and production of proinflammatory cytokines.
