Abstract | Macroautophagy/autophagy is a process through which the phagophores engulf non-essential or damaged cellular materials, forming double-membrane autophagosomes (APs) and fusing with lysosomes/vacuoles, after which the materials are degraded for recycling purposes. Autophagy is associated with increased cell survival under different stress conditions. AP-lysosome/vacuole fusion is a critical step in autophagy. Some mutant cells can accumulate phagophores under autophagy-induction conditions. Autophagy is interrupted when accumulated phagophores cannot fuse with lysosomes/vacuoles, resulting in a significant decrease in cell survivability. However, phagophore-lysosome/vacuole fusion has been reported in related mammalian cells and yeast mutant cells. This observation indicates that it is possible to restore a partial autophagy process after interruption. Furthermore, these findings indicate that phagophore closure is not a prerequisite for its fusion with the lysosome/vacuole in the mutant cells. The phagophore-lysosome/vacuole fusion strategy can significantly rescue defective autophagy due to failed phagophore closure. This commentary discusses the fusion of phagophores and lysosomes/vacuoles and implications of such fusion events. |
