Subcellular Location Cell membrane Single-pass type I membrane protein Early endosome Note=Upon complex formation with CD36 and TLR6, internalized through dynamin-dependent endocytosis (PubMed:20037584). Colocalizes with RFTN1 at cell membrane and then together with RFTN1 moves to endosomes, upon lipopolysaccharide stimulation.
Domain PF13516 Leucine Rich repeat
PF13855 Leucine rich repeat
PF01582 TIR domain
Function

Cooperates with LY96 and CD14 to mediate the innate immune response to bacterial lipopolysaccharide (LPS) (PubMed:27022195). Acts via MYD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response (PubMed:9237759, PubMed:10835634, PubMed:27022195). Also involved in LPS-independent inflammatory responses triggered by free fatty acids, such as palmitate, and Ni(2+). Responses triggered by Ni(2+) require non-conserved histidines and are, therefore, species-specific (PubMed:20711192). Both M.tuberculosis HSP70 (dnaK) and HSP65 (groEL-2) act via this protein to stimulate NF-kappa-B expression (PubMed:15809303). In complex with TLR6, promotes sterile inflammation in monocytes/macrophages in response to oxidized low-density lipoprotein (oxLDL) or amyloid-beta 42. In this context, the initial signal is provided by oxLDL- or amyloid-beta 42-binding to CD36. This event induces the formation of a heterodimer of TLR4 and TLR6, which is rapidly internalized and triggers inflammatory response, leading to the NF-kappa-B-dependent production of CXCL1, CXCL2 and CCL9 cytokines, via MYD88 signaling pathway, and CCL5 cytokine, via TICAM1 signaling pathway, as well as IL1B secretion. Binds electronegative LDL (LDL(-)) and mediates the cytokine release induced by LDL(-) (PubMed:23880187). Stimulation of monocytes in vitro with M.tuberculosis PstS1 induces p38 MAPK and ERK1/2 activation primarily via TLR2, but also partially via this receptor (PubMed:16622205).

PMID Cancer type Relation to immunity Evidence sentences
28179508Colon CarcinomaPromote immunity (infiltration)Tumor microenvironment colonization by engineered Salmonella appeared to induce the infiltration of abundant immune cells such as monocytes/macrophages and neutrophils via TLR4 signaling.
26928313Hepatocellular CarcinomaInhibit immunity (T cell function)TLR4-mediated BCL6 upregulation was crucial for PD-1(hi) B-cell induction by HCC environmental factors, and that effect was abolished by IL4-elicited STAT6 phosphorylation. Importantly, upon encountering PD-L1(+) cells or undergoing PD-1 triggering, PD-1(hi) B cells acquired regulatory functions that suppressed tumor-specific T-cell immunity and promoted cancer growth via IL10 signals.
22583829Oral Cavity Squamous Cell CarcinomaInhibit immunityRole of toll-like receptor 4 on the immune escape of human oral squamous cell carcinoma and resistance of cisplatin-induced apoptosis.
18199559Skin Squamous Cell CarcinomaPromote immunity (T cell function)TLR4-deficient C3H/HeJ mice developed more tumors relative to the TLR4-normal C3H/HeN mice. Interestingly, the cell-mediated immune response was mediated by IFN-gamma in C3H/HeN mice and by interleukin (IL)-17 in C3H/HeJ mice. Moreover, C3H/HeN mice had elevated circulating levels of IFN-gamma following topical application of DMBA, whereas IL-17 was elevated in C3H/HeJ mice. The results of this study indicate that TLR4 plays an important role in the prevention of DMBA skin tumorigenesis and that this is associated with differences in the T-cell subtype activated.
20826579Adrenal Cortex Carcinoma; AdenomaPromote immunity (T cell function)Real-time PCR analysis of human ACC (n=8), adenoma (n=8), and ACC cell lines (SW13, NCI-H295R, and HAC15) revealed a significant down-regulation of TLR4, MD2 (myeloid differentiation protein-2), and cluster of differentiation 14 (CD14) mRNA compared with normal human adrenal cortex and adrenocortical cells in primary culture. Western blot analysis of MAPK, AKT, activator protein-1, and nuclear factor-κB signaling revealed that the ACC cell lines are unresponsive to lipopolysaccharide action. Restoration of TLR4 signaling by stable transfection of TLR4-CD14 plasmid into NCI-H295R cells sensitized them to lipopolysaccharide incubation as shown by nuclear factor-κB activation and decreased cell viability and induced apoptosis in these cells
19881547Colorectal CarcinomaPromote immunityThe knockout of toll-like receptor 4 (TLR4), the receptor for HMGB1, also resulted in a deficient immune response against OXP-treated CT26 cells. However, patients carrying the TLR4 loss-of-function allele exhibited reduced progression-free and overall survival, as compared with patients carrying the normal TLR4 allele.
19826413Ovarian CarcinomaInhibit immunity (T cell function)In MyD88(+) SCOV3 cells, LPS or PTX binding to TLR4 induced IRAK4 activation and cJun phosphorylation, activated the NF-kappaB pathway and promoted interleukin (IL)-8, IL-6, vascular endothelial growth factor and monocyte chemotactic protein-1 production and resistance to drug-induced apoptosis. Silencing of TLR4 in SCOV3 cells with small interference RNA resulted in phosphorylated-cJun (p-cJun) downregulation and a loss of PTX resistance. In PTX-sensitive, MyD88(neg) A2780 cells, TLR4 stimulation upregulated TRIF, and TLR4 silencing eliminated this effect.
17974996Prostate Carcinoma; MelanomaPromote immunityWe show that (a) activating TLR4 signaling in two different tumor cell lines in vitro modifies the tumor outgrowth in vivo; (b) this effect is not due to a direct consequence of TLR4 signaling on the proliferation/apoptosis balance of the tumor cells; (c) the T-cell compartment is somehow involved in the described phenomenon because the inhibitory effect observed is not seen in athymic nude mice; and (d) tumor-infiltrating lymphocytes purified from tumors induced by TLR4-activated cells show strong induction of IFN gamma transcript in detriment of interleukin-10 transcript, suggesting a change in their functionality.
29661854Skin CarcinomaInhibit immunity immunotherapy targetGiven the tremendous cancer burden incurred by NMSC, further exploration of the use of TLR4 antagonists in NMSC chemoprevention strategies is certainly warranted.
23904461MelanomaPromote immunity (T cell function); essential for immunotherapyAutologous monocyte-derived dendritic cells (DCs) electroporated with synthetic messenger RNA (mRNA) encoding a CD40 ligand, a constitutively active Toll-like receptor 4 and CD70, together with mRNA encoding fusion proteins of a human leukocyte antigen (HLA)-class II targeting signal (DC-LAMP) and a melanoma-associated antigen (MAA); either MAGE-A3, MAGE-C2, tyrosinase or gp100) (TriMixDC-MEL) are superiorly immunogenic.
21455984Other Mammary Carcinoma of MousePromote immunityCell mediated immune responses through TLR4 prevents DMBA-induced mammary carcinogenesis in mice. T cells of TLR4 deficient mice produced elevated levels of IL-17 and lower levels of IFN-γ relative to WT mice. IL-12 secreted by CD11c(+) cells was higher in WT mice, whereas greater amounts of IL-23 were produced by CD11c(+) cells from TLR4 deficient mice. The results of this study indicate that TLR4 plays an important role in the prevention of DMBA induced mouse mammary tumorigenesis and efforts to divert the cell-mediated immune response may, therefore, prove to be beneficial in the prevention of mammary tumors.
29270668Rectal CarcinomaPromote immunityThe better outcome is likely due to the release of HMGB1, which triggers the maturation of dendritic cells (DCs) via TLR4 activation, and the subsequent recruitment of PD-1+?tumor-infiltrating lymphocytes to the tumor site, where they participate in immune-scavenging.
24321786Lung CarcinomaInhibit immunityHere we show that autophagy induced by TLR4 or TLR3 activation enhances various cytokine productions through promoting TRAF6 (TNF receptor-associated factor 6, E3 ubiquitin protein ligase) ubiquitination and thus facilitates migration and invasion of lung cancer cells. Remarkably, inhibition of autophagy by chemical or genetic approaches blocked TLR4- or TLR3-induced Lys63 (K63)-linked ubiquitination of TRAF6 that was essential for activation of MAPK and NFKB (nuclear factor of kappa light polypeptide gene enhancer in B-cells) pathways, both of which were involved in the increased production of the cytokines.
22915070Mantle Cell LymphomaInhibit immunity; Candidate for immunotherapy targetThe activation of TLR4 signaling in MCL cells by LPS induced MCL proliferation and up-regulated the secretion of cytokines like interleukin-6 (IL-6), IL-10, and vascular endothelial growth factor (VEGF). Knockdown of TLR4 on MCL cells abrogated the effect of LPS on MCL cells in term of cell growth or secretion of the cytokines and evasion of the immune system. Thus, TLR4 signaling molecules may be novel therapeutic targets in patients with MCL.
22139376MelanomaPromote immunityIFNβ produced by TLR4-activated tumor cells is involved in improving the antitumoral immune response. Transcriptional analysis showed that TLR4 activation on B16 cells induced changes in the expression of type I IFN and type I IFN-related genes. Most importantly, culture supernatants from LPS-B16 cells improved the maturation of bone marrow-derived dendritic cells (BMDC) from TLR4-deficient mice, upregulating the expression of interleukin-12 and costimulatory molecules on those cells.
20675592Hepatocellular CarcinomaInhibit immunityTumor cell-released TLR4 ligands stimulate Gr-1+CD11b+F4/80+ cells to induce apoptosis of activated T cells. Blockade of TLR4 signaling could further reduce the apoptosis-inducing capacity of Gr-1(+)CD11b(+)F4/80(+) cells and enhance the suppressive effect of 4-1BBL/soluble form of programmed death-1 on tumor growth.
21949133Lung CarcinomaPromote immunityActivation of Toll-like receptor 4 (TLR4) triggers the innate immune response and leads to the induction of adaptive immunity. TLR4 agonists are known to function as immunostimulants and exhibit promising therapeutic potential for cancer immunotherapy.

Content High-throughput screening data (e.g. CRISPR-Cas9, shRNA and RNAi) for T cell-mediated killing. Genetic screen techniques can identify mechanisms of tumor cell resistance (e.g., PTPN2) and sensitivity (e.g., APLNR) to killing by cytotoxic T cells, the central effectors of anti-tumor immunity. After comprehensively searching, eight groups of screening data sets were collected in the current database. In this tab, users can check whether their selected genes cause resistance or increase sensitivity to T cell-mediated killing in various data sets.
