Summary: In young striatum, lithium increased tissue viability and decreased ROS generation, accompanied by enhanced expression of autophagy-related proteins. However, in aged striatum, lithium reduced autophagic flux and increased oxygen consumption rate. Ultrastructural changes in aged rats' striatum included electron-dense mitochondria with disarranged cristae after consuming lithium for 30 days.

Summary: A key feature of neurodegenerative diseases (NDs) like Alzheimer's disease (AD) and Parkinson's disease (PD) is the accumulation of misfolded protein aggregates, which have limited effective therapeutic agents. TFEB, a regulator of lysosomal biogenesis and autophagy, plays a crucial role in protein aggregate degradation and is regarded as a promising therapeutic target for these NDs.

Summary: Autophagy is a cellular mechanism responsible for maintaining internal balance by degrading cellular components, but it can be altered in various diseases, including Parkinson's disease. Parkinson's disease is a multifactorial disease, with mutations in the LRRK2 gene affecting the autophagy mechanism and compromising cell viability.

Summary: This study demonstrates the critical role of chaperone-mediated autophagy (CMA) in maintaining proper mitochondria dynamics. Loss of this regulatory control may occur in Parkinson's disease (PD), leading to impaired mitochondria function. Increasing CMA activity promotes MARCHF5 turnover, reduces mitochondria fragmentation, and alleviates mitochondrial dysfunction under oxidative stress.

Summary: This review summarizes animal models of genetic defects in various pathogenesis of Parkinson's disease, including abnormal encoding of alpha-synuclein, defects in the autophagy-lysosome system, defects in the ubiquitin protease system, and mitochondria-related dysfunction. The advantages, limitations, and application directions of these models are discussed, providing a reference for the application of animal models in Parkinson's disease research and therapy.

Summary: Oxidative stress is implicated in various pathological conditions, with antioxidant-rich foods playing a role in maintaining cellular redox balance. Sulforaphane, enriched in cruciferous vegetables like broccoli, induces cellular antioxidant responses by activating TFEB. This activation helps in protecting cells against oxidative stress through a combination of autophagy and detoxification pathways.

Summary: This study investigated the role of catalase and lysosomal function in catalase-knockout mice, revealing that mature adult catalase-KO mice exhibited accelerated aging phenotypes compared to wild-type mice, with leaky lysosomes, impaired autophagy, and mTORC1 activation.

Summary: Dysfunction of the endolysosomal system is associated with the pathogenesis of Parkinson's disease (PD), and genetic variants in the GBA gene are a common risk factor. GCase deficiency in neurons and glia may contribute to PD by promoting the accumulation and spread of alpha-synuclein aggregates. Dysregulation of lipids, including sphingolipids, phospholipids, and cholesterol, as well as neuroinflammation and the interaction between GCase and LRRK2 protein, are also implicated in PD pathogenesis.

Summary: The S-nitrosoglutathione reductase (GSNOR) is a key denitrosating enzyme that regulates protein S-nitrosation. Research has shown that GSNOR plays an important physiological role in Parkinson's disease (PD), controlling CDK5-mediated autophagy and contributing to the pathology.

Summary: Parkinson's disease is a neurodegenerative disorder caused by the loss of dopaminergic neurons. Mutations in PRKN and PINK1 genes are responsible for early onset Parkinson's. Our research shows that PINK1 can activate PRKN to promote mitophagy. This signaling pathway offers potential for the development of therapeutics.

Summary: PINK1 and PRKN, known to cause Parkinson's disease when mutated, form a quality control mitophagy pathway studied mainly in cultured cells. However, the contribution of the PINK1-PRKN pathway to mitophagy in vivo is disputed, with conflicting results from studies using mitophagy reporters mt-Keima and mito-QC. This study compared the performance of the two reporters in cell culture and mice under PINK1-PRKN activating stress, finding that mito-QC was less sensitive than mt-Keima, particularly for PINK1-PRKN mitophagy. These results indicate that the differences in sensitivity may explain conflicting reports and caution against using mito-QC as a reporter for PINK1-PRKN mitophagy.

Summary: Reactive oxygen species (ROS) generated from incomplete oxygen reduction can interact with and influence the function of various targets, including DNA, lipids, and proteins. AMP-activated protein kinase (AMPK), known as a major sensor of intracellular energy status, has been shown to play a crucial role in regulating cellular processes such as autophagy and lysosomal function. Through its modulation, AMPK can participate in the crosstalk between mitochondria and lysosomes by perceiving signals related to mitochondrial dynamics and transducing them to lysosomes, thereby impacting autophagic flux. Future studies should focus on the specific contribution of different AMPK subpopulations to the autophagic pathway, considering the tissue-specific regulation and localization of AMPK.

Summary: This study reveals that LRRK2 negatively regulates lysosome degradative activity in macrophages and microglia through transcriptional mechanisms. Depletion or inhibition of LRRK2 enhances lysosomal proteolytic activity and expression of lysosomal hydrolases, while the Parkinson's disease mutant LRRK2 G2019S suppresses lysosomal degradative activity and gene expression. MiT-TFE transcription factors are identified as mediators of LRRK2-dependent control of lysosomal gene expression.
