Autophagy (or autophagocytosis; from the Greek αὐτόφαγος, autóphagos, meaning "self-devouring" [1] and κύτος, kýtos, meaning "hollow") [2] is the natural, conserved degradation of the cell that removes unnecessary or dysfunctional components through a lysosome-dependent regulated mechanism. [3]
When host cells die, either by apoptosis or by cell injury due to an infection, phagocytic cells are responsible for their removal from the affected site. [9] By helping to remove dead cells preceding growth and development of new healthy cells, phagocytosis is an important part of the healing process following tissue injury.
Once inside the cell, viruses use the cell's biological machinery to their own advantage, forcing the cell to make hundreds of identical copies of themselves. Although phagocytes and other components of the innate immune system can, to a limited extent, control viruses, once a virus is inside a cell the adaptive immune responses, particularly ...

Nanoparticles range in size from 10 - 1000 nm (or 1 μm) and they can be made from natural or artificial polymers, lipids, dendrimers, and micelles. [ 1 ] [ 5 ] Most polymers used for nanoparticle drug delivery systems are natural, biocompatible , and biodegradable , which helps prevent contamination in the CNS.
