introduction : the innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (pamps) by toll-like receptors (tlrs). interaction of bacterial pamps by tlrs results in activation of innate and acquired immunity. fimh adhesin, a minor component of type 1 fimbriae encoded by uropathogenic escherichia coli (upec) is a pamp of tlr4 that ...
The pathogenesis of the sepsis syndrome is critically dependent on activation of the innate immune response. Innate immunity plays a direct role in the development of sepsis and is also crucial for the activation and modulation of later antigen-specifi c adaptive immune responses. Nearly all of the clinical manifestations of sepsis and the systemic infl ammatory response syndrome (SIRS) can be ...
The immune response of a host to a pathogen is typically described as either innate or adaptive. The innate form of the immune response is conserved across all organisms, including insects. Previous and recent research has focused on the nature of the insect immune system and the results imply that the innate immune response of insects is more robust and specific than previously thought. Primin...
The innate immune response is initiated by the interaction of stereotypical pathogen components with genetically conserved receptors for extracytosolic pathogen-associated molecular patterns (PAMPs) or intracytosolic nucleic acids. In multicellular organisms, this interaction typically clusters signal transduction molecules and leads to their activations, thereby initiating signals that activat...
celiac disease (cd) is an autoimmune enteropathy induced by the ingestion of gluten in genetically predisposed individuals who carry the hla dq2 or dq8 alleles. the etiology is multifactorial involving genetic and environmental factors, immune response, and intestinal dysbiosis. the innate and acquired t-cell mediated immunity play important roles in the pathogenesis of this disease, particular...
background hepatitis c virus (hcv) is able to down-regulate innate immune response. it is important to know the immune pathways that this virus interacts with. hcv non-structural protein 3 (ns3) plays an important role in this viral feature. hcv ns3 protein could affect the expression of antiviral protein such as viperin, and interleukin 28whichare important proteins in antiviral response. conc...
Dendritic cells (DCs) play a critical role in the immune response to viral infection through the facilitation of cell-intrinsic antiviral activity and the activation of adaptive immunity. HIV-1 infection of DCs triggers an IRF3-dependent innate immune response, which requires the activity of cyclic GAMP synthase (cGAS). We report the results of a targeted RNAi screen utilizing primary human mon...
The maternal innate immune system plays an important role both in normal pregnancy as well as hypertensive disorders of pregnancy including preeclampsia (PE). We propose four pathways that involve excessive innate immunity that lead to most forms of PE. Pre-existing endothelial dysfunction plus pregnancy leads to an excessive innate immune response resulting in widespread inflammation, placenta...
The innate immune response is evolutionary conserved among organisms. The complement system forms an important and efficient immune defense mechanism. It consists of plasma proteins that participate in microbial detection, which ultimately results in the production of various molecules with antimicrobial activity. Thioester-containing proteins (TEPs) are a superfamily of secreted effector prote...
