Autophagy regulation in macrophages and neutrophils

Autophagy is a conserved proteolytic mechanism that degrades cytoplasmic material including cell organelles. Accumulating evidence exists that autophagy also plays a major role in immunity and inflammation. Specifically, it appears that autophagy protects against infections and inflammation. Here, we review recent work performed in macrophages and neutrophils, which both represent critical phagocytes in mammalians.
