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, 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.

Primary rat cortical neurons at DIV7 were used for experiments. A-D Western blot analyses of LC3-I and LC3-II in lysates in neurons exposed to increasing concentrations of bafilomycin baf or chloroquine CQ for 24 h. Besides LC3, levels of other autophagy substrates can be used to monitor autophagic flux. Classically, autophagy was considered to be a random degradation system, but recent studies have revealed that several specific substrates are preferentially degraded by autophagy, of which the best studied example is p62 also known as SQSTM1/sequestome 1. Autophagy or autophagocytosis from the Ancient Greek αὐτόφαγος autóphagos, meaning "self-devouring" and κύτος kýtos, meaning "hollow" is the natural, regulated mechanism of the cell that removes unnecessary or dysfunctional components. In the extreme case of starvation, the breakdown of cellular components promotes cellular survival by maintaining cellular energy levels. 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.

Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4. References. 1.

We have generated a VCPR155H/+ mouse model which recapitulates the disease phenotype and impaired autophagy typically observed in patients with VCP disease. Autophagy-modifying agents, such as rapamycin and chloroquine, at pharmacological doses have previously shown to alter the autophagic flux. Autophagy changes the REDOX equilibrium. Cells with disrupted autophagy functions show a decrease in glucose uptake and glycolysis flux, and inhibition of the glucose metabolism-related antioxidant capacity. Studies have shown that autophagy-enhancing drugs increase the tolerance of tumor to mitochondrial damage 22–24.
