Sarcopenia has a complex pathophysiology that encompasses metabolic dysregulation and muscle ultrastructural changes. Among the drivers of intracellular changes fibers in sarcopenia, mitochondria their quality control pathways play relevant roles. Mononucleated stem cells/satellite cells (MSCs) have been attributed critical role repair after an injury. The involvement supporting MSC-directed is unclear. There evidence reduction mitochondrial biogenesis blunts repair, thus indicating delivery functional to injured muscles can be harnessed limit fibrosis enhance restoration function. Injection autologous respiration-competent from uninjured sites damaged tissue shown reduce infarct size cell survival preclinical models ischemia-reperfusion. Furthermore, incorporation donor into MSCs enhances lung cardiac repair. This strategy also tested for regeneration purposes traumatic injuries. Indeed, systemic promotes restores mass function while reducing during recovery In this review, we discuss contribution altered MSC sarcopenia illustrate prospect harnessing as therapeutic against age-related sarcopenia.

Acute pancreatitis (AP) is an inflammatory disease of the pancreas and a complex process involving multiple factors, with mitochondrial damage playing crucial role. Mitochondrial dysfunction now considered key driver in development AP. This often presents as increased oxidative stress, altered membrane potential permeability, DNA mutations. Under stress conditions, dynamics ROS production increase, leading to decreased potential, imbalanced calcium homeostasis, activation permeability transition pore. The release (mtDNA), recognized damage-associated molecular patterns, can activate cGAS-STING1 NF-κB pathway induce pro-inflammatory factor expression. Additionally, mtDNA inflammasomes, interleukin subsequent tissue inflammation. review summarizes relationship between mitochondria AP explores protective strategies diagnosis treatment this disease. Future research on acute benefit from exploring promising avenues such antioxidants, inhibitors, new therapies that target dysfunction.

Spinal cord injury (SCI) involves a continuous and dynamic cascade of complex reactions, with mitochondrial damage dysfunction-induced energy metabolism disorders playing central role throughout the process. These not only determine severity secondary injuries but also influence potential for axonal regeneration. Given critical disturbances in pathology SCI, strategies such as enhancing transport within axons to alleviate local deficits, or transplanting autologous allogeneic mitochondria restore supply damaged tissues, have emerged approaches SCI repair. aim modulate inflammatory responses apoptosis. Preclinical studies initially demonstrated that transplantation (MT) significantly reduces neuronal death promotes regeneration following spinal injury. MT achieves this by regulating signaling pathways MAPK/ERK PI3K/Akt, promoting expression growth-associated protein-43 (GAP-43) neurons, inhibiting apoptosis-related proteins like Grp78, Chop, P-Akt, thereby survival neurons. Additionally, plays vascular endothelial growth factor, facilitating tissue repair, reducing secretion pro-inflammatory cytokines TNF-α, IL-1β, IL-6. Furthermore, modulates apoptosis decreasing p-JNK, member MAPK family. In summary, reviewing detailed mechanisms underlying pathological processes we emphasize changes endogenous post-SCI exogenous This review aims provide insights basis developing more effective clinical treatments SCI.
