The polarized structure and long neurites of neurons pose a unique challenge for proper mitochondrial distribution. It is widely accepted that mitochondria move from the cell body to axon ends and vice versa; however, we have found that mitochondria originating from the axon ends moving in the retrograde direction never reach to the cell body, and only a limited number of mitochondria moving in the anterograde direction from the cell body arrive at the axon ends of mouse hippocampal neurons. Furthermore, we have derived a mathematical formula using the Fokker-Planck equation to characterize features of mitochondrial transport, and the equation could determine altered mitochondrial transport in axons overexpressing parkin. Our analysis will provide new insights into the dynamics of mitochondrial transport in axons of normal and unhealthy neurons.

Innate immunity is crucial in orchestrating the brain immune response, however, glioblastoma multiforme (GBM) has evolved sophisticated mechanisms to evade innate immune surveillance, posing significant challenges for current immunotherapies. Here, a therapeutic strategy is reported that aims at reactivating innate immune responses in GBM via targeted induction of mitochondrial stress, thereby enhancing tumor immunogenicity. Specifically, innate immune-stimulating nanoparticles (INSTNA) are developed, encapsulating positively charged iridium-based complexes (Ir-mito) and small interfering RNA against Methylation-Controlled J protein (si-MCJ) to attenuate mitochondrial respiration.

Background And Purpose: Ciprofol, a novel intravenous anesthetic, has been shown to exert protective effects against ischemic stroke, a leading cause of death and disability; however, its molecular mechanisms remain unclear. This study aimed to explore the molecular mechanisms underlying the neuroprotective effects of ciprofol using metabolomics.
Methods: This study used a middle cerebral artery occlusion (MCAO) rat model to simulate cerebral ischemia-reperfusion injury (CIRI).

The present study investigated the effects of ultrasound-assisted L-lysine (Lys) in regulating mitochondrial function to enhance the color stability of porcine . The results indicated that the meat treated with ultrasound-assisted Lys showed higher * and * values, and lower * and * values. Simultaneously, the myoglobin (Fe) content significantly increased ( < 0.

Objectives: Lung cancer represents a major global healthcare challenge, characterized by high annual incidence and mortality rates worldwide. Although targeted therapies for lung cancer have advanced, treatment outcomes for advanced-stage patients remain suboptimal. This investigation examines the role of the translocase of the inner mitochondrial membrane (TIMM)8A-TIMM13 complex in lung cancer and evaluates its potential as a novel therapeutic target.

Mitochondria play a crucial role in reactive oxygen species (ROS)-dependent rheumatic diseases, including ankylosing spondylitis, osteoarthritis (OA), systemic lupus erythematosus (SLE) and scleroderma. Mitochondrial DNA (mtDNA), which encodes mitochondrial proteins, is more vulnerable to oxidants compared to nuclear DNA. When mtDNA gets damaged, it leads to mitochondrial dysfunction, such as electron transport chain impairment and loss of mitochondrial membrane potential.
