The Immunoglobulin E-Toll-Like Receptor Network

A comprehensive map of the toll-like receptor signaling network

Recognition of pathogen-associated molecular signatures is critically important in proper activation of the immune system. The toll-like receptor (TLR) signaling network is responsible for innate immune response. In mammalians, there are 11 TLRs that recognize a variety of ligands from pathogens to trigger immunological responses. In this paper, we present a comprehensive map of TLRs and interl...

P-82: The Role of Toll-Like Receptor 2 in Ectopic Pregnancy

Background: The innate immune system is our first line of defense against invading pathogens. Toll–like receptors (TLRs) have been identified as a key role in mediating the function of innate immune system which bridges the gap between innate and adaptive immunity. For example, TLR2 is able to act as a homodimer to recognize lipoteichoic acids of Gram-positive bacteria but as a heterodimer with...

Effects of Oral Probiotic Feeding on Toll-Like Receptor Gene Expression of the Chicken’s Cecal Tonsil

Background: It was proposed that probiotics may influence immune system through direct or indirect exposure. Direct exposure is mostly mediated by surface receptors. Toll-like receptors (TLRs) are conserved molecular sensors which could be triggered via some pathogen associated structures, hence, modulate the immune responses. This study was conducted to elucidate the impact of lactobacillus ac...

Toll-Like Receptor 4 and Toll-IL-1 Receptor

Toll-like receptor downstream signaling

The family of Toll-like receptors (TLRs) senses conserved structures found in a broad range of pathogens, causing innate immune responses that include the production of inflammatory cytokines, chemokines and interferons. The signal transduction is initiated from the Toll/interleukin-1 receptor (TIR) domain of TLRs after pathogen recognition. Almost all TLRs use a TIR-containing adapter MyD88 to...
