One Type of Fat May Accelerate Brain Aging, But Scientists Say There’s a Fix

A higher level of the fat that gathers around organs has been linked to faster brain aging in a new study, with glucose and insulin the likely mediators.

The study, led by a team from Ben-Gurion University of the Negev (BGU) in Israel, suggests that reducing visceral fat can protect against brain atrophy.

Like other parts of the body, the brain doesn’t necessarily age at a consistent rate: wear and tear can increase or decrease, depending on numerous factors. Faster brain aging typically means a faster decline in mental performance, and a higher risk of brain diseases.

Blood as the mirror and modulator of aging: mechanistic insights and rejuvenation strategies

Aging is a complex process influenced by changes in our blood that affect how quickly we age. Scientists have shown that blood contains important molecules and cellular components — including proteins, metabolites, and immune cells — that can either accelerate or slow aging. Tools such as the ‘proteomic aging clock’ predict age and disease risk based on blood protein profiles, whereas emerging multi-omics approaches integrate metabolomic and immunomic data. Large-scale analyses of circulating factors reveal how these components change with age and identify markers of organ-specific aging. Certain blood-borne molecules can predict diseases such as heart disease and Alzheimer disease. These findings demonstrate that aging does not occur uniformly across tissues. Overall, studying diverse blood components provides valuable insight into aging biology and offers opportunities to develop strategies that promote healthier aging and improve long-term health.

Nanotechnology-Driven Therapeutic Innovations in Neurodegenerative Disorders: A Focus on Alzheimer’s and Parkinson’s Disease

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.

Epigenetic Skin Aging and Its Reversal to Improve Skin Longevity across Ethnicities and Phototypes Using a Dihydromyricetin-Containing Serum: Results from a Prospective, Single-Cohort Study — Dermatology and Therapy

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.

“Micro-managing” immune activation and protein turnover: microglial lysosomes in the context of health and disease

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 Develops ‘Anti-Aging Vaccine’ Targeting Cellular Aging

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.
