The retinal pigment epithelium (RPE) is a highly specialized and polarized epithelial cell layer that plays an important role in sustaining the structural functional integrity of photoreceptors. However, death RPE common pathological feature various diseases, especially age-related macular degeneration (AMD) diabetic retinopathy (DR). Mitophagy, as programmed self-degradation dysfunctional mitochondria, crucial for maintaining cellular homeostasis survival under stress. contains high density mitochondria necessary it to meet energy demands, so severe stimuli can cause mitochondrial dysfunction excess generation intracellular reactive oxygen species (ROS), which further trigger oxidative stress-involved mitophagy. In this review, we summarize classical pathways mitophagy investigate its progression aiming provide new therapeutic strategy treating degenerative diseases. AMD DR. AMD, excessive ROS production promotes by activating Nrf2/p62 pathway, while DR, may suppress FOXO3-PINK1/parkin signaling pathway or TXNIP-mitochondria-lysosome-mediated

The mitochondrion is also a major site for maintaining redox homeostasis between reactive oxygen species (ROS) generation and scavenging. quantity, quality, functional integrity of mitochondria are crucial regulating intracellular the normal physiological function cells. role oxidative stress in human disease well established, particularly inflammatory bowel gastrointestinal mucosal diseases. Oxidative could result from an imbalance ROS antioxidative system. Mitochondria both main sites production target ROS. It vicious cycle which initial ROS-induced mitochondrial damage enhanced that, turn, leads to further eventually massive intestinal cell death. can be significantly mitigated by mitophagy, clears damaged mitochondria. In this review, we aimed review molecular mechanisms involved regulation mitophagy their relationship some We believe reviews provide new ideas scientific basis researching antioxidants preventing diseases related damage.

Since their initial discovery around two decades ago, the yeast autophagy-related (Atg)8 protein and its mammalian homologues of light chain 3 (LC3) γ-aminobutyric acid receptor associated proteins (GABARAP) families have been key for tremendous expansion our knowledge about autophagy, a process in which cytoplasmic material become targeted lysosomal degradation. These are ubiquitin-like that directly conjugated to lipid autophagy membrane upon induction thus providing marker pathway, allowing studies autophagosome biogenesis maturation. Moreover, ATG8 function recruit components core machinery as well cargo selective Importantly, comprehensive structural biochemical vitro required lipidation, genetic manipulation various model organisms, provided novel insight into molecular mechanisms pathophysiological roles mATG8 proteins. Recently, it has evident conjugation also involved intracellular pathways processes not related autophagy. This review focuses on functions other pathways, links disease.
