I-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...
متن کاملToll-like receptor 9 trafficking and signaling for type I interferons requires PIKfyve activity.
Toll-like receptors (TLRs) traffic to distinct membranes for signaling. TLR7 and TLR9 recognize viral nucleic acids in the endosomes and induce robust anti-viral program. Signaling from these TLRs bifurcate at the level of distinct endosomal compartments, namely VAMP3(+) and LAMP(+) endosomes, to mediate the induction of cytokine and type I interferon (IFN) genes, respectively. The formation of...
متن کامل“Toll-free” pathways for production of type I interferons
Pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) are recognized by different cellular pathogen recognition receptors (PRRs), which are expressed on cell membrane or in the cytoplasm of cells of the innate immune system. Nucleic acids derived from pathogens or from certain cellular conditions represent a large category of PAMPs/DAMPs that trigger pr...
متن کاملToll-like receptor expression and induction of type I and type III interferons in primary airway epithelial cells.
Interferons (IFNs) are a critical component of the first line of antiviral defense. The activation of Toll-like receptors (TLRs) expressed by dendritic cells triggers different signaling cascades that result in the production of large amounts of IFNs. However, the functional consequences of TLR activation and differential IFN production in specific cell populations other than antigen-presenting...
متن کاملDifferential induction of Toll-like receptors & type 1 interferons by Sabin attenuated & wild type 1 polioviruses in human neuronal cells
BACKGROUND & OBJECTIVES Polioviruses are the causative agent of paralytic poliomyelitis. Attenuated polioviruses (Sabin oral poliovirus vaccine strains) do not replicate efficiently in neurons as compared to the wild type polioviruses and therefore do not cause disease. This study was aimed to investigate the differential host immune response to wild type 1 poliovirus (wild PV) and Sabin attenu...
