Crosstalk pathways between Toll-like receptors and the complement system.
The Toll-like receptors (TLRs) and complement are key innate defense systems that are triggered rapidly upon infection. Although both systems have been investigated primarily as separate entities, an emerging body of evidence indicates extensive crosstalk between complement and TLR signaling pathways. Analysis of these data suggests that the complement-TLR interplay reinforces innate immunity o...
متن کاملMolecular Determinants of Crosstalk between Nuclear Receptors and Toll-like Receptors
Nuclear receptors (NRs) repress transcriptional responses to diverse signaling pathways as an essential aspect of their biological activities, but mechanisms determining the specificity and functional consequences of transrepression remain poorly understood. Here, we report signal- and gene-specific repression of transcriptional responses initiated by engagement of toll-like receptors (TLR) 3, ...
متن کاملMicrobial hijacking of complement-toll-like receptor crosstalk.
Crosstalk between complement and Toll-like receptors (TLRs) coordinates innate immunity. We report a previously unknown immune subversion mechanism involving microbial exploitation of communication between complement and TLRs. Porphyromonas gingivalis, a major oral and systemic pathogen with complement C5 convertase-like activity, synergizes with C5a (fragment of complement protein C5) to incre...
متن کاملToll-Like Receptors in Liver Fibrosis: Cellular Crosstalk and Mechanisms
Toll-like receptors (TLRs) are pattern recognition receptors that distinguish conserved microbial products, also known as pathogen-associated molecular patterns (PAMPs), from host molecules. Liver is the first filter organ between the gastrointestinal tracts and the rest of the body through portal circulation. Thus, the liver is a major organ that must deal with PAMPs and microorganisms translo...
متن کاملI-23: Reproduction and Toll Like Receptors(TLRs
Female and male reproductive tracts are of interest sites to study of immune system because they encounter specific infections such as those are sexually transmitted. Furthermore, female reproductive tract is in close contact with allogenic sperms and transmitted microorganisms during intercourse and semi allogenic fetus during pregnancy. In mammals, there are two types of immune responses, the...
