先天性免疫系统通过模式识别受体(PRR)感测病原体,所述模式识别受体发出信号以诱导效应细胞因子,例如I型干扰素(IFN)。我们将IFNε定性为I型IFN,因为它通过Ifnar 1和Ifnar 2受体发出信号以诱导IFN调节的基因。与其他I型IFN相比,IFNε不由已知的PRR途径诱导,而是由雌性生殖道(FRT)的上皮细胞组成型表达并受生殖调节。IFNε缺陷小鼠对常见性传播感染(STI)、单纯疱疹病毒(HSV)-2和鼠衣原体感染FRT的易感性增加。因此,IFNε是一种有效的抗病原体和免疫调节细胞因子,在对抗代表主要全球健康和社会经济负担的STI中可能是重要的。
The innate immune system senses pathogens by pattern recognition receptors (PRR) that signal to induce effector cytokines, such as type I interferons (IFNs). We characterized IFNε 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, IFNε was not induced by known PRR pathways, but was instead constitutively expressed by epithelial cells of the female reproductive tract (FRT) and hormonally regulated. Ifnε-deficient mice had increased susceptibility to infection of the FRT by common sexually transmitted infections (STIs) Herpes Simplex Virus (HSV)-2 and Chlamydia muridarum. IFNε is thus a potent anti-pathogen and immunoregulatory cytokine that may be important in combating STIs which represent a major global health and socioeconomic burden.
