Toll-like receptors (TLRs) are a large family of germ-line encoded pattern recognition receptors (PRRs) that recognize pathogen-associated molecular patterns and evoke the relevant innate immune responses. TLR8 is a member of several endosome nucleic acid-sensing TLRs; however little attention has been paid to murine TLR8 (mTLR8) compared with other endosome nucleic acid-sensing TLRs. In the pr...

BACKGROUND Host defense against invading pathogens is triggered by various receptors including toll-like receptors (TLRs). Activation of TLRs is a pivotal step in the initiation of innate, inflammatory, and antimicrobial defense mechanisms. Human beta-defensin 2 (HBD-2) is a cationic antimicrobial peptide secreted upon gram-negative bacterial perturbation in many cells. Stimulation of various T...

Introduction The induction of an appropriate immune response upon infection of an invading pathogen is controlled by host pattern recognition receptors (PRRs)* that specifically recognise essential structural components of infectious agents termed pathogen-associated molecular patterns (PAMPs) (1-3). Detection of PAMPs by PRRs triggers intracellular signalling pathways leading to the expression...

Among mechanisms development this pathology, changes in neuroimmune occurring brain during prolonged consumption its withdrawal have recently become focus numerous studies. Ethanol leads to activat...

Toll-like receptors (TLRs) are highly conserved trans-membrane proteins that play an important role in the detection and recognition of microbial pathogens. The key product of TLR signalling in antigen presenting cells is the production of inflammatory cytokines and proteins. The TLR pathway plays an important role in mediating whole body inflammation, which has been implicated in the developme...

Results Mean age of study population was 8.08 ± 3.41 years. 75% of patients were in WHO clinical stage I and II, whereas 25% in stage III. 29% HIV children had severe immunosuppression. TLR-1 showed neutral expression in majority (96%) of HIV children. For TLR-7, 53.5% HIV children showed upregulation, whereas 32% and 14.5% showed downregulation and neutral expression, respectively. TLR-8 expre...

Toll-like receptors (TLRs) are major components of the innate immune system that recognize the conserved molecular structures of pathogens (pathogen-associated molecular patterns; PAMPs). TLRs are found in many different cell types, ranging from epithelial to immunocompetent cells. TLR binding triggers the expression of several adapter proteins and downstream kinases, leading to the induction o...

Toll-like receptors (TLRs) 3, 7, 8, and 9 are localized to intracellular compartments where they encounter foreign or self nucleic acids and activate innate and adaptive immune responses. The endoplasmic reticulum (ER)-resident membrane protein, UNC93B1, is essential for intracellular trafficking and endolysosomal targeting of TLR7 and TLR9. TLR8 is phylogenetically and structurally related to ...

Innate immune response in Drosophila is mediated by signaling through Toll receptors. In mammals, Toll-like receptors (TLRs), comprising a large family, recognize a specific pattern of microbial components. So far, the roles of TLR2, TLR4, TLR5, TLR6, and TLR9 have been revealed. The recognition of microbial components by TLRs leads to activation of innate immunity, which provokes inflammatory ...
