Autophagy occurs in the following sequence of steps:

Induction by activation of mTOR complex 1

• Nucleation of autophagosome formation by ATG9

• Closure of the membrane cup to form autophagosome

• Fusion of the autophagosome with lysosomes, catalyzed by SNAREs.

• Digestion of the inner membrane and the lumenal contents of the autophagosome

Autophagosome, or autophagic vesicle

formation of a flattened double-membrane cup-shaped structure that envelops a region of the cytosol or an entire organelle.

Autophagy (“eating oneself”)

When cells are placed under stressful conditions, they have the capacity to recycle macromolecules for use as nutrients in a process of lysosomal degradation.

There are 4 paths from different sources feed substances into lysosomes for digestion:

• Endocytosis

• Phagocytosis

• Macropinocytosis

• Autophagy
