Figure 2

The age-dependent decline in mitophagy might provide the mechanism to explain the known interrelationship between increased ROS, decreased bioenergetic capacity, and age-dependent functional decline. Agents such as spermidine and urolithin A appear to stimulate mitophagy and thereby prevent age-related pathologies, which are described in more detail in the main text.
