Summary: Mitochondria play a crucial role in providing energy for nerve cells and protecting the nervous system from external stressors. However, excessive accumulation of damaged mitochondria can lead to neuronal death. Mitophagy, a pathway responsible for removing damaged mitochondria, is important for neuronal protection. Dysfunctional mitochondria are commonly observed in neurological disorders, and drugs targeting mitophagy can improve symptoms. This article reviews the role of mitophagy in various neurological diseases and discusses drug and non-drug approaches to promote mitophagy for therapeutic purposes. However, further research is needed to develop safer and more targeted drugs, and the clinical application of drugs targeting mitophagy may face challenges and potential side effects.

Summary: Mitophagy dysfunction caused by gene mutations is associated with the development of Parkinson's Disease (PD). However, the association between the variants of mitophagy-related genes and the treatment with levodopa (LD) in PD patients has not been well explored. This study investigated the association of 14 variants of the PRKN gene with LD treatment in PD patients. The results suggest that while age at onset of symptoms, duration of PD, and LD treatment and dosage can influence the occurrence of dyskinesia, the investigated PRKN variants did not show a significant association.

Summary: We characterized the content of extracellular vesicles (EVs) in the in vivo interstitial fluid (IF) and found an abundance of proteins associated with mitophagy and secretory autophagy. Comparisons between in vivo and in vitro EVs revealed an elevation of mitophagy proteins in CD81+ EVs under metabolic stress conditions. The export of cellular mitochondria proteins into CD81+ EVs was confirmed through various experimental techniques. These findings suggest that the 4T1 in vivo model can be a versatile tool to study IF EVs and the export of mitophagy proteins has broad implications for mitochondrial function and cellular immunology.

Summary: Mitochondria, as the powerhouse of eukaryotic cells, are crucial in the pathogenesis of depression. Impaired mitophagy may lead to increased inflammation and mitochondrial dysfunction in depression patients. Therapeutic interventions targeting modulating mitophagy could potentially be beneficial in treating depression.

Summary: This study develops a platform for Alzheimer's disease (AD) therapy using nanosized mesenchymal-stem-cells-derived extracellular vesicles with high expression of tyrosine phosphatase-2 (SHP2). The platform demonstrates high blood-brain barrier penetration ability, delivers SHP2 to the brain, and induces significant mitophagy of neuronal cells, thereby alleviating mitochondrial damage, apoptosis, and neuroinflammation, leading to improved synaptic loss and cognitive decline in an AD mouse model.

Summary: "Treatment of Glioblastoma: Targeting Mitophagy and Mitochondrial Apoptosis Pathways" is a review article that emphasizes the urgent need to develop novel methods for treating Glioblastoma (GBM). GBM exhibits intra- and inter-tumor heterogeneity, leading to drug resistance and tumor recurrence. Recent studies have shown that drugs targeting mitophagy and mitochondrial apoptosis pathways, along with nanotechnology, offer promising approaches for GBM treatment.

Summary: Mitochondria, the primary ATP-producing organelles, play a crucial role in sustaining pump function in the heart. Under stress conditions, cardiomyocytes maintain mitochondrial quality through dynamic changes and mitophagy, affecting cardiac function and cell survival. Various mechanisms of mitophagy in the heart have functional significance and potential applications for cardiac conditions.

Summary: Mitochondria play crucial roles in cellular metabolism and regulated cell death, with mitophagy serving as a key mechanism for maintaining cellular homeostasis. Mitophagy is regulated by various endogenous metabolites and is essential for the bidirectional interplay between mitophagy and cellular metabolisms.

Summary: A phenanthroline copper(ii) complex CPT8 modified with an alkyl chain-linked triphenylphosphonium group showed potent antiproliferative activity against TNBC cells and induced mitophagy through activation of PINK1/Parkin and BNIP3 pathways. It also exhibited anti-angiogenic effects by decreasing the tube formation ability of HUVEC and downregulating the expression of Nrf2, VEGF, and CD34. Furthermore, CPT8 inhibited vasculogenic mimicry formation and suppressed the metastatic potential of MDA-MB-231 cells, making it a promising metal drug candidate for TNBC treatment.

Summary: In this study, the researchers investigated the effect of mitophagy activation on Zika virus replication. They found that niclosamide-induced mitophagy inhibits Zika virus replication by eliminating fragmented mitochondria. Knockdown of PINK1 promotes Zika virus infection and rescues the anti-Zika virus effect of mitophagy activation, confirming the role of ubiquitin-dependent mitophagy in limiting Zika virus replication. These findings demonstrate the importance of mitophagy in the host response to Zika virus and identify PINK1 as a potential therapeutic target.

Summary: Research has shown that mitophagy plays an important role in regulating type 2 diabetes and metabolic homeostasis. Defective mitophagy is linked to the development of insulin resistance, which leads to various diseases. Restoring mitophagy can be a reliable target for treating type 2 diabetes. Recent studies have shown that certain phytochemicals can prevent dysfunction of beta-cells by inducing mitophagy.
