Skin aging is the most prominent phenotype of host aging and is the consequence of a combination of genes and environment. Improving skin aging is essential for maintaining the healthy physiological function of the skin and the mental health of the human body. Mitochondria are vital organelles that play important roles in cellular mechanisms, including energy production and free radical balance. However, mitochondrial metabolism, mitochondrial dynamics, biogenesis, and degradation processes vary greatly in various cells in the skin. It is well known that mitochondrial dysfunction can promote the aging and its associated diseases of the skin, resulting in the damage of skin physiology and the occurrence of skin pathology. In this review, we summarize the important role of mitochondria in various skin cells, review the cellular responses to vital steps in mitochondrial quality regulation, mitochondrial dynamics, mitochondrial biogenesis, and mitochondrial phagocytosis, and describe their importance and specific pathways in skin aging.

Most animals experience abrupt developmental transitions involving major tissue remodeling, but the links with metabolic changes remain poorly understood. We examined ontogenetic changes in mitochondrial volume, oxidative capacity, oxygen consumption capacity, and anaerobic capacity across four organs (gut, liver, heart, and hindlimb muscle) in Xenopus laevis from metamorphosis to adulthood. These organs differ in the extent of developmental transformation.

Loss-of-function variants in the lipid transporter ABCA7 substantially increase the risk of Alzheimer's disease, yet how they impact cellular states to drive disease remains unclear. Here, using single-nucleus RNA-sequencing analysis of human brain samples, we identified widespread gene expression changes across multiple neural cell types associated with rare ABCA7 loss-of-function variants. Excitatory neurons, which expressed the highest levels of ABCA7, showed disrupted lipid metabolism, mitochondrial function, DNA repair and synaptic signalling pathways.

Mitochondrial dysfunction is a shared hallmark of neurodegenerative disorders, including Alzheimer's disease (AD) and tauopathies among others. Pathological alterations of the microtubule-associated protein Tau can disrupt mitochondrial dynamics, transport, and function, ultimately leading to neuronal toxicity and synaptic deficits. Understanding these processes is crucial for developing therapeutic interventions.

Leber's hereditary optic neuropathy (LHON), a mitochondrial disorder marked by central vision loss, exhibits incomplete penetrance and male predominance. Since there are no adequate models for understanding the rapid vision loss associated with LHON, we generated induced pluripotent stem cells (iPSCs) from LHON patients carrying the pathogenic m.3635G > A mutation and differentiated them into retinal pigment epithelium (RPE) cells.
