Autophagy is a process where non-functional or unnecessary cellular components are removed and recycled so healthy new cellular components can be built. This “cellular housekeeping” is crucial for immune health and the body’s ability to respond to immune aging. The most studied type of autophagy concerns sub-cellular recycling. For example, damaged mitochondria can be removed, which promotes survival of the cell.
