Beschreibung:
The innate immune system senses pathogens through pattern-recognition receptors (PRRs) that signal to induce effector cytokines, such as type I interferons (IFNs). We characterized IFN-epsilon as a type I IFN because it signaled via the Ifnar1 and Ifnar2 receptors to induce IFN-regulated genes. In contrast to other type I IFNs, IFN-epsilon was not induced by known PRR pathways; instead, IFN-epsilon was constitutively expressed by epithelial cells of the female reproductive tract (FRT) and was hormonally regulated. Ifn-epsilon-deficient mice had increased susceptibility to infection of the FRT by the common sexually transmitted infections (STIs) herpes simplex virus 2 and Chlamydia muridarum. Thus, IFN-epsilon is a potent antipathogen and immunoregulatory cytokine that may be important in combating STIs that represent a major global health and socioeconomic burden.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3617553/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3617553/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fung, Ka Yee -- Mangan, Niamh E -- Cumming, Helen -- Horvat, Jay C -- Mayall, Jemma R -- Stifter, Sebastian A -- De Weerd, Nicole -- Roisman, Laila C -- Rossjohn, Jamie -- Robertson, Sarah A -- Schjenken, John E -- Parker, Belinda -- Gargett, Caroline E -- Nguyen, Hong P T -- Carr, Daniel J -- Hansbro, Philip M -- Hertzog, Paul J -- R01 AI053108/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Mar 1;339(6123):1088-92. doi: 10.1126/science.1233321.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Innate Immunity and Infectious Diseases, Monash Institute of Medical Research, Monash University, Clayton, Victoria, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23449591" target="_blank"〉PubMed〈/a〉
