Flow (Cell Surface): TLR4 Antibody (HTA125) - Azide Free [NB100-56727] - Validation of the neutralizing effect of this antibody on TLR4 activity. The TLR4/MD-2/CD14/IL-8 Prom/LUCPorter HeLa cells were plated in 96-well white plates at 1 x 10^5 cells/well. After 16 h, cells were preincubated with different amounts of this antibody for 1 h and then stimulated with 10 ng/ml LPS for 6 h. Luciferase activity was then directly analyzed using the one-step luciferase reporter assay reagent. Data Summary: It inhibited LPS-mediated TLR4 activity in the TLR4/MD-2/CD14/IL-8 Prom/LUCPorter cell line.![Flow Cytometry: TLR4 Antibody (HTA125) - Azide and BSA Free [NB100-56727]](https://resources.bio-techne.com/images/products/TLR4-Antibody-HTA125-Azide-Free-Flow-Cytometry-NB100-56727-img0016.jpg "Flow Cytometry: TLR4 Antibody (HTA125) - Azide and BSA Free [NB100-56727]")

Background: TLR4
TLR4 signaling occurs through two distinct pathways: The MyD88 (myeloid differentiation primary response gene 88)-dependent pathway and the MyD88-independent (TRIF-dependent, TIR domain-containing adaptor inducing IFN-beta) pathway (3, 5-7). The MyD88-dependent pathway occurs mainly at the plasma membrane and involves the binding of MyD88-adaptor-like (MAL) protein followed by a signaling cascade that results in the activation of transcription factors including nuclear factor-kappaB (NF-kappaB) that promote the secretion of inflammatory molecules and increased phagocytosis (5-7). Conversely, the MyD88-independent pathway occurs after TLR4-MD2 complex internalization in the endosomal compartment. This pathway involves the binding of adapter proteins TRIF and TRIF-related adaptor molecule (TRAM), a signaling activation cascade resulting in IFN regulatory factor 3 (IRF3) translocation into the nucleus, and secretion of interferon-beta (INF-beta) genes and increased phagocytosis (5-7).
Given its expression on immune-related cells and its role in inflammation, TLR4 activation can contribute to various diseases (6-8). For instance, several studies have found that TLR4 activation is associated with neurodegeneration and several central nervous system (CNS) pathologies, including Alzheimer's disease, Parkinson's disease, and Huntington's disease (6, 7). Furthermore, TLR4 mutations have been shown to lead to higher rates of infections and increased susceptibility to sepsis (7-8). One potential therapeutic approach aimed at targeting TLR4 and neuroinflammation is polyphenolic compounds which include flavonoids and phenolic acids and alcohols (8).
Alternative names for TLR4 includes 76B357.1, ARMD10, CD284 antigen, CD284, EC 3.2.2.6, homolog of Drosophila toll, hToll, toll like receptor 4 protein, TOLL, toll-like receptor 4.
