Autophagy is a basic feature of cell biology

with a unique regulatory pathway

which can selectively degrade specific proteins

organelles

and invade bacteria. It is generally believed that autophagy is a protective reaction of cells in the pathological and physiological state. Recent studies have shown that in certain metabolic disorders and other neurodegenerative diseases

infection and immunity diseases autophagy play a different role. In certain diseases

inhibition of autophagy can lead to an exacerbation of the disease;and in certain diseases

vice versa

autophagy activation can lead to disease occurrence and development. So what kind of role does autophagy have in lung inflammatory disease? This article reviews the progress in the research of autophagy in lung inflammatory diseases.
