A life-span extending form of autophagy employs the vacuole-vacuole fusion machinery.

Abstract excerpt

While autophagy is believed to be beneficial for life-span extension, it is controversial which forms or aspects of autophagy are responsible for this effect. We addressed this topic by analyzing the life span of yeast autophagy mutants under caloric restriction, a longevity manipulation.
