• Official Full Name

    toll-like receptor 4

  • Overview

    Cooperates with LY96 and CD14 to mediate the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MYD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Also involved in LPS-independent inflammatory responses triggered by Ni(2+). These responses require non-conserved histidines and are, therefore, species-specific.

Q&As (5)

Ask a question
How does TLR4 signaling intersect with the nuclear factor-kappa B (NF-κB) pathway? 11/20/2021

TLR4 signaling activates NF-κB, a transcription factor, promoting the expression of pro-inflammatory genes involved in immune responses.

Can you explain the molecular events following TLR4 activation upon ligand binding? 08/14/2020

Ligand binding induces conformational changes in TLR4, leading to the recruitment of adaptor proteins, such as MyD88, and the activation of downstream signaling cascades.

What is the role of the TLR4 signaling pathway in innate immunity? 02/18/2019

The TLR4 signaling pathway activates innate immune responses by detecting PAMPs, triggering the release of cytokines, and promoting the elimination of pathogens.

Can you elaborate on the crosstalk between TLR4 and other pattern recognition receptors (PRRs)? 10/02/2018

TLR4 engages in crosstalk with other PRRs, forming a network that enhances the sensitivity and specificity of the immune response to diverse pathogens.

Can you describe the molecular structure of TLR4 and its functional domains? 04/23/2018

TLR4 consists of extracellular leucine-rich repeats (LRRs) for ligand binding, a transmembrane domain, and an intracellular Toll/interleukin-1 receptor (TIR) domain for signaling.
