Inflammation is a central feature of an effective immune response, which functions to eliminate pathogens and other foreign material, and promote recovery; however, dysregulation of the inflammatory response is associated with a wide variety of disease states. The autophagy-lysosome pathway is one of 2 major degradative pathways used by the cell and serves to eliminate long-lived and dysfunctional proteins and organelles to maintain homeostasis. Mounting evidence implicates the autophagy-lysosome pathway as a key player in regulating the inflammatory response; hence many inflammatory diseases may fundamentally be diseases of autophagy-lysosome pathway dysfunction. The recent identification of TFEB and TFE3 as master regulators of macroautophagy/autophagy and lysosome function raises the possibility that these transcription factors may be of central importance in linking autophagy and lysosome dysfunction with inflammatory disorders. Here, we review the current state of knowledge linking TFEB and TFE3 to the processes of autophagy and inflammation and highlight several conditions, which are linked by these factors.
炎症是有效免疫反应的一个核心特征,其功能是消除病原体和其他异物,并促进恢复;然而,炎症反应的失调与多种疾病状态有关。自噬-溶酶体途径是细胞使用的两种主要降解途径之一,用于消除寿命长和功能失调的蛋白质和细胞器以维持体内平衡。越来越多的证据表明自噬-溶酶体途径是调节炎症反应的关键因素;因此,许多炎症性疾病可能从根本上是自噬-溶酶体途径功能障碍的疾病。最近发现 TFEB 和 TFE3 是巨自噬/自噬和溶酶体功能的主要调节因子,这提高了这些转录因子在将自噬和溶酶体功能障碍与炎症障碍联系起来方面可能具有核心重要性的可能性。在这里,我们回顾了将 TFEB 和 TFE3 与自噬和炎症过程联系起来的现有知识,并强调了由这些因素联系在一起的几种情况。
