Autophagy (or autophagocytosis) (from the Ancient Greek αὐτόφαγος autóphagos, meaning "self-devouring"[1] and κύτος kýtos, meaning "hollow"[2]) is the natural, regulated mechanism of the cell that removes unnecessary or dysfunctional components.[3] It allows the orderly degradation and recycling of cellular components.[4][5] Three forms of autophagy are commonly described: macroautophagy, microautophagy, and chaperone-mediated autophagy (CMA). In macroautophagy, expendable cytoplasmic constituents are targeted and isolated from the rest of the cell within a double-membraned vesicle known as an autophagosome,[6][7] which, in time, fuses with an available lysosome, bringing its specialty process of waste management and disposal; and eventually the contents of the vesicle (now called an autolysosome) are degraded and recycled. In disease, autophagy has been seen as an adaptive response to stress, promoting survival of the cell; but in other cases it appears to promote cell death and morbidity. In the extreme case of starvation, the breakdown of cellular components promotes cellular survival by maintaining cellular energy levels. The name "autophagy" was in existence and frequently used from the middle of the 19th century[8]. In its present usage, the term autophagy was coined by Belgian biochemist Christian de Duve in 1963 based on his discovery of the functions of lysosome.[3] The identification of autophagy-related genes in yeast in the 1990s allowed researchers to deduce the mechanisms of autophagy,[9][10][11][12][13] which eventually led to the award of the 2016 Nobel Prize in Physiology or Medicine to Japanese researcher Yoshinori Ohsumi.[14] 1000 Scientific Studies all about Autophagy: Autophagy in the pathogenesis of disease Autophagy fights disease through cellular self-digestion Autophagy: process and function Methods in Mammalian Autophagy Research Autophagy regulates lipid metabolism Autophagy and Metabolism Autophagy: Renovation of Cells and Tissues Autophagy as a Regulated Pathway of Cellular Degradation Autophagy in immunity and inflammation Autophagy and Aging Autophagy and the Integrated Stress Response mTOR regulation of Autophagy Regulation Mechanisms and Signaling Pathways of Autophagy Role of Autophagy in cancer Bcl-2 Antiapoptotic Proteins Inhibit Beclin 1-Dependent Autophagy Induction of Autophagy and inhibition of tumorigenesis by beclin 1 Autophagy in Health and Disease: A Double-Edged Sword Methods for monitoring Autophagy AMPK and mTOR regulate Autophagy through direct phosphorylation of Ulk1 LC3 and Autophagy The role of Autophagy during the early neonatal starvation period Death by design: apoptosis, necrosis and Autophagy Autophagy in cell death: an innocent convict?
