先天性免疫是指一种快速但非特异性的宿主防御反应。先天免疫系统包括特定的免疫细胞群、上皮屏障和许多分泌介质,包括细胞因子、趋化因子和防御肽。先天免疫细胞现在也被认为在癌症和病理性炎症中发挥重要作用。先天免疫依赖于病原体识别后经由模式识别受体(PRR)引起的快速信号转导和由可溶性介质(包括细胞因子)进行的细胞:细胞通信。参与先天免疫信号传导的大多数细胞因子使用分子级联,包括受体相关的Jak蛋白酪氨酸激酶和STAT(信号转导和转录激活因子)转录调节因子。在这里,我们专注于STAT蛋白在三个主要的先天免疫亚群中的作用:中性粒细胞,巨噬细胞和树突状细胞(DC)。虽然这一领域的知识现在才刚刚出现,但了解这些细胞类型的分子调控对于开发治疗人类疾病(如炎症,自身免疫和癌症)的新方法是必要的。
The term innate immunity typically refers to a quick but nonspecific host defense response against invading pathogens. The innate immune system comprises particular immune cell populations, epithelial barriers, and numerous secretory mediators including cytokines, chemokines, and defense peptides. Innate immune cells are also now recognized to play important contributing roles in cancer and pathological inflammatory conditions. Innate immunity relies on rapid signal transduction elicited upon pathogen recognition via pattern recognition receptors (PRRs) and cell:cell communication conducted by soluble mediators, including cytokines. A majority of cytokines involved in innate immune signaling use a molecular cascade encompassing receptor-associated Jak protein tyrosine kinases and STAT (signal transducer and activator of transcription) transcriptional regulators. Here, we focus on roles for STAT proteins in three major innate immune subsets: neutrophils, macrophages, and dendritic cells (DCs). While knowledge in this area is only now emerging, understanding the molecular regulation of these cell types is necessary for developing new approaches to treat human disorders such as inflammatory conditions, autoimmunity, and cancer.
