Self and nonself: how autophagy targets mitochondria and bacteria

Cell Host Microbe. 2014 Apr 9;15(4):403-11. doi: 10.1016/j.chom.2014.03.012.

Abstract

Autophagy is an evolutionarily conserved pathway that transports cytoplasmic components for degradation into lysosomes. Selective autophagy can capture physically large objects, including cell-invading pathogens and damaged or superfluous organelles. Selectivity is achieved by cargo receptors that detect substrate-associated "eat-me" signals. In this Review, we discuss basic principles of selective autophagy and compare the "eat-me" signals and cargo receptors that mediate autophagy of bacteria and bacteria-derived endosymbionts-i.e., mitochondria.
