Abstract Mitochondria, the most crucial energy-generating organelles in eukaryotic cells, play a pivotal role regulating energy metabolism. However, their significance extends beyond this, as they are also indispensable vital life processes such cell proliferation, differentiation, immune responses, and redox balance. In response to various physiological signals or external stimuli, sophisticated mitochondrial quality control (MQC) mechanism has evolved, encompassing key like biogenesis, dynamics, mitophagy, which have garnered increasing attention from researchers unveil specific molecular mechanisms. this review, we present comprehensive summary of primary mechanisms functions regulators involved major components MQC. Furthermore, critical regulated by MQC its diverse roles progression systemic diseases been described detail. We discuss agonists antagonists targeting MQC, aiming explore potential therapeutic research prospects enhancing stabilize function.

Mitochondria are critical cellular energy resources and central to the life of neuron. Mitophagy selectively clears damaged or dysfunctional mitochondria through autophagic machinery maintain mitochondrial quality control homeostasis. Mature neurons postmitotic consume substantial energy, thus require highly efficient mitophagy pathways turn over mitochondria. Recent evidence indicates that is pivotal pathogenesis neurological diseases. However, more work needed study pathway components as potential therapeutic targets. In this review, we briefly discuss characteristics nonselective autophagy selective autophagy, including ERphagy, aggrephagy, mitophagy. We then introduce mechanisms Parkin-dependent Parkin-independent under physiological conditions. Next, summarize diverse repertoire membrane receptors phospholipids mediate Importantly, review role in neurodegenerative diseases Alzheimer's disease, Parkinson's amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a fatal multisystem disease characterized by progressive death of motor neurons, loss muscle mass, and impaired energy metabolism. More than 40 genes are now known to be associated with ALS, which together account for the majority familial forms ALS only 10% sporadic cases. To date, there no consensus on pathogenesis makes it difficult develop effective therapy. Accumulating evidence indicates that mitochondria, play an important role in cellular homeostasis, earliest targets abnormalities their structure functions contribute development bioenergetic stress progression. Mitochondria highly dynamic organelles, stability maintained through number key regulatory pathways. Mitochondrial homeostasis dynamically regulated via mitochondrial biogenesis, clearance, fission/fusion, trafficking; however, processes providing “quality control” distribution organelles prone dysregulation ALS.

Translocator protein (TSPO), a 18 kDa found in the outer mitochondrial membrane, has historically been associated with transport of cholesterol highly steroidogenic tissues though it is all cells throughout mammalian body. TSPO also molecular transport, oxidative stress, apoptosis, and energy metabolism. levels are typically low central nervous system (CNS), but significant upregulation observed activated microglia during neuroinflammation. However, there few specific regions that have reported to higher than rest brain under normal conditions.

Amyotrophic Lateral Sclerosis (ALS) is considered the prototype of motor neuron disease, characterized by loss and muscle waste. A well-established pathogenic hallmark ALS mitochondrial failure, leading to bioenergetic deficits. So far, pharmacological interventions for disease have proven ineffective. Trimetazidine (TMZ) described as a metabolic modulator acting on different cellular pathways. Its efficacy in enhancing muscular cardiovascular performance has been widely described, although its molecular target remains elusive. We addressed mechanisms underlying TMZ action neuronal experimental paradigms. To this aim, we treated murine SOD1G93A-model-derived primary cultures cortical spinal enriched neurons, well motor-neuron-like cell line overexpressing SOD1G93A, with TMZ. first profile cultures, demonstrating significant dysfunction that reversed acute treatments. then investigated effect promoting autophagy processes impact morphology. Finally, demonstrated effectiveness terms functionality ALS-rpatient-derived peripheral blood mononuclear cells (PBMCs).
