自噬是一种溶酶体降解途径,在细胞内稳态中起重要作用。先前的工作表明,自噬相关基因5(ATG5)在弓形虫耐药性中起着关键作用。在这里,我们展示了参与微管相关蛋白1轻链3(LC3)与磷脂酰乙醇胺偶联的自噬蛋白的盒,包括ATG7,ATG3,以及Atg12-ATG5-Atg16L1复合体在体外和体内控制弓形虫的关键作用。相反,降解性自噬途径的药理学调节或其他必需自噬基因的基因缺失没有实质性影响。相反,连接系统是靶向Lc3和干扰素-γ效应器到弓形虫空泡膜上并随后破坏它所必需的。这些数据表明,在典型的自噬过程中重组细胞内膜的泛素样结合系统对于将免疫效应物正确地靶向病原体利用的细胞内空泡膜是必要的。
Autophagy is a lysosomal degradation pathway that is important in cellular homeostasis. Prior work showed a key role for the autophagy related 5 (Atg5) in resistance to Toxoplasma gondii. Here we show that the cassette of autophagy proteins involved in the conjugation of microtubule associated protein 1 light chain 3 (LC3) to phosphatidylethanolamine, including Atg7, Atg3, and the Atg12-Atg5-Atg16L1 complex play crucial roles in the control of T. gondii in vitro and in vivo. In contrast, pharmacologic modulation of the degradative autophagy pathway or genetic deletion of other essential autophagy genes had no substantial effects. Rather the conjugation system was required for targeting of LC3 and interferon-γ effectors onto the vacuolar membrane of T. gondii and its consequent disruption. These data suggest that the ubiquitin-like conjugation systems that reorganize intracellular membranes during canonical autophagy are necessary for proper targeting of immune effectors to the intracellular vacuole membranes utilized by pathogens.
