Neurodegenerative disorders entail a progressive loss of neurons in cerebral and peripheral tissues, coupled with the aggregation of proteins exhibiting altered physicochemical properties. Crucial to these conditions is the gradual degradation of the central nervous system, manifesting as impairments in mobility, aberrant behaviors, and cognitive deficits. Mechanisms such as proteotoxic stress, neuroinflammation, oxidative stress, and programmed cell death contribute to the ongoing dysfunction and demise of neurons. Presently, neurodegenerative diseases lack definitive cures, and available therapies primarily offer palliative relief. The integration of nanotechnology into medical practices has significantly augmented both treatment efficacy and diagnostic capabilities.
Skin aging is driven by intrinsic and extrinsic factors. Epigenetic alterations are one primary hallmark of aging and powerful biomarkers of biological skin age. To investigate epigenetic skin aging mechanisms and their regulation as a skin longevity approach across diverse ethnicities and phototypes, we assessed epidermal methylomes from white, African, and Asian donors.
We collected epidermis samples from 17 multi-ethnic donors with diverse phototypes using a newly established tape-stripping method followed by array-based DNA methylation profiling to investigate the robustness of DNA methylation clocks across diverse ethnic backgrounds. Additionally, we conducted a clinical study with 60 participants representing Fitzpatrick phototypes I–VI. Diverse clinical parameters and biological skin age of the volunteers were determined at baseline and after applying a serum containing the natural epigenetic inhibitor dihydromyricetin (DHM) for 8 weeks to investigate skin longevity effects across phototypes.
Data analysis revealed that age-dependent DNA hypermethylation is conserved across populations and affects genes essential for keratinocyte vitality and longevity. A newly developed epidermal methylation clock accurately predicted biological age in multi-ethnic cohorts, confirming the robustness of epigenetic age estimation across phototypes. Topical application of a DHM-containing serum significantly reduced epidermal DNA methylation age. Epigenetic rejuvenation was associated with clinical improvements, including reduced skin roughness and wrinkle visibility and occupancy, and increased dermal echogenicity.
Microglial lysosomes immune activation and protein turnover.
In addition to its role in protein and organelle homeostasis, lysosomes are also involved in nutrient sensing, cell metabolism, immune response, and programmed cell death.
Lysosomes are heterogeneous subpopulations and their dysfunction has been associated with the pathogenesis of several neurodegenerative diseases.
Although lysosomal biogenesis, transport, and heterogeneity are well studied in neurons, the researchers in this review discuss microglial lysosome biology its regulation, composition, and function, and how these properties are linked to immune activation, aging, and certain disease pathologies. sciencenewshighlights Science Mission https://sciencemission.com/microglial-lysosomes

Russia is developing what officials have described as a “vaccine against aging,” a gene therapy drug aimed at slowing cellular aging by blocking a receptor linked to age-related changes in the body, the deputy science minister said Thursday.
Denis Sekirinsky, Russia’s deputy science and higher education minister, said the experimental treatment would target the RAGE receptor, which he said triggers cellular aging when activated.
“The RAGE gene is a receptor whose activation launches the aging of the cell. Blocking this gene, on the contrary, can prolong its youth,” Sekirinsky said at a healthy longevity conference in the Volga city of Saransk, according to the state-run TASS news agency.
Statistics show clear differences in the population’s immune system according to sex: men are more susceptible to infections and cancers, while women have stronger immune responses, which translate, for example, into better responses to vaccines. Even so, with a more reactive immune system, the probability of the body attacking itself also increases, causing 80% of autoimmune disease development to occur in women.
In this context, understanding the aging of the immune system is key since, with age, the composition of immune cells changes and their protective functions deteriorate, causing a greater susceptibility to diseases. However, understanding how sex influences this profound transformation was not possible until now.
A new study by the Barcelona Supercomputing Center—Centro Nacional de Supercomputación (BSC-CNS) published today in Nature Aging demonstrated, for the first time, that immunological aging follows different dynamics between men and women, identifying the cells and genes responsible for the process, and providing a molecular explanation for the differences that previously were only observed globally in the population.
