TLR4 transfected 293T cells probed with TLR4 monoclonal (biotin) antibody (Lane 4) and probed first with affinity-purified anti-peptide antibodies, followed by an incubation with biotin-labelled anti-TLR4 monoclonal antibody (Lane 5). Human plasmocytoid dendritic cells probed with TLR4 monoclonal antibody (Lane 6), human monocytes probed with TLR4 monoclonal antibody (Lane 7) and with affinity-purified anti-peptide antibodies (Lane 8).

Block/Neutralize: TLR4 Antibody (HTA125) [NB100-56723] - Human monocyte-derived DCs were pre-incubated wit TLR-neutralizing antibodies including TLR4 antibody (NB100-56723) for 1 h. Afterwards, DCs were infected with H. pylori G27 (MOI 5) and the levels of the costimulatory molecule CD86 and the maturation marker CD83 were analyzed by FACS on CD11c+ cells 24 h post-infection. Data are presented as mean +/- SD of five independent experiments. *p<=0.05, **p<=0.005, ***p<=0.0005. Asterisks on top of bars indicate significance relative to non-neutralized, H. pylori-primed control cells.

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.
