Altogether, our data are the first reported activation of TLR8 by protozoan RNA and demonstrate both the critical role of TLR8 in human blood-stage malaria and its unique functionality in the human immune system.
As the receptor of single stranded RNA (ssRNA), toll-like receptor 8 (TLR8) has potential in the treatment of tumors, microbial infection, and inflammatory diseases.
As this response was inhibited by a blocking anti-TNFα antibody, drug targeting HIV ssRNA-driven TLR8 activation may serve as a potential therapeutic target to reduce chronic immune activation and inflammation leading to CVD in HIV+ patients.
Because immunosuppression is common in HNSCC, we hypothesized that adding a proinflammatory TLR8 agonist to cetuximab therapy might result in enhanced T-lymphocyte stimulation and anti-EGFR-specific priming.<b>Experimental Design:</b> Fourteen patients with previously untreated HNSCC were enrolled in this neoadjuvant trial and treated preoperatively with 3 to 4 weekly doses of motolimod (2.5 mg/m<sup>2</sup>) and cetuximab.
Both TLR8 and TLR7 are functional candidate genes owing to their key roles as pathogen recognition receptors and, in the case of TLR7, overexpression has been associated directly with murine autoimmune disease.
By genome scanning, evidence of linkage between chromosome Xp22 and asthma and related atopic disorders has previously been obtained.Xp22 harbours the TLR7 and TLR8 genes.
Carriage of the C allele in three SNPs of TLR3 (rs3775290, rs3775291, and rs5743312), the C allele in TLR7 (rs3853839) in females only, and the C allele in TLR8 (rs3764879) in males only were significantly higher in SVC group than CHC group (P < 0.001), while carriage of the T allele in TLR7 (rs179008) in females only and the A allele in TLR8 (rs3764880) in both males and females were significantly higher in CHC infection more than SVC group (P < 0.001).
Compared with controls, TLR1 and TLR4 were highly expressed, TLR9 was moderately expressed, TLR7 was weakly expressed and TLR8 expression was neutral in neonates with MAS.
Data herein indicating that proinflammatory cytokines are reduced, whereas IFN-λ production and TLR8 and 9 MFI are augmented in those aMCI in whom AD conversion is not observed suggest that the ability to mount stronger antiviral response within an antiiflammatory milieu associates with lack of AD conversion.
Drugs targeting macrophage TLR8-linked signaling pathways may modulate the innate immune response to acute HIV infection by reducing viral replication.
Exposure of trophoblast to HBV significantly induced the expression of TLR7 (P<0.001), TLR8 (P=0.005), MyD88 (P=0.004), interferon (IFN)-α (P=0.004), IFN-β (P<0.001) and interleukin (IL)-8 (P=0.001).
Furthermore, no association was found between the rs5744168 (TLR5) polymorphism and SLE susceptibility in Europeans or between the rs187084 (TLR8) or rs352140 (TLR9) polymorphisms and SLE susceptibility in Asians.
Furthermore, knockdown of TLR8 completely attenuated collagen expression in monocytes exposed to HCV, and knockdown of TLR7 partially attenuated this expression, suggesting roles for TLR7/8 in induction of fibrocytes in HCV infection.
