Aging & Longevity

With the aging of the global population, neurodegenerative diseases have become a major public health challenge. Currently, there are many limitations in the traditional treatment of neurodegenerative diseases, such as medicine, deep brain stimulation, transcranial magnetic stimulation, and transcranial direct current stimulation, including the inability to penetrate the blood-brain barrier (BBB) accurately and challenges in achieving precise and quantitative control during the treatment...

Advanced maternal age is a key factor in female infertility, primarily due to declines in ovarian reserve and oocyte quality. However, the metabolic mechanisms underlying reproductive aging remain unclear. Here, we show that uridine levels in the plasma and ovaries of aged mice are significantly reduced compared with young controls. Building on this, we find that uridine supplementation significantly improves meiotic maturation, fertilization, and early embryonic development of aged oocytes,...

The attachment of Post-Translational Modifications (PTMs) to proteins regulates their activities and stability. Here we utilized the nematode Caenorhabditis elegans to test whether UFMylation, a PTM which affects key biological functions, regulate aging and protein homeostasis (proteostasis). We find that lowering UFMylation extends lifespan and mitigates the toxicity of aggregation-prone proteins that underlie the development of neurodegenerative disorders in humans. Mass spectrometric analysis...

Female reproductive aging has systemic health implications, yet tissue-level dynamics remain poorly understood. Here we integrate deep learning analysis of 1,112 histology images with RNA sequencing from 659 samples across seven female reproductive organs in donors aged 20-70 years. We uncover asynchronous trajectories: the ovary ages gradually, whereas the uterus shows an abrupt molecular and morphological shift around menopause. This uterine transition is independently supported by plasma...

CONCLUSIONS AND IMPLICATIONS: Witnessing interparental violence in childhood is significantly linked to higher frailty in adulthood. Interventions addressing domestic violence may contribute to healthier aging outcomes.

Biological and synthetic replacement-based ageing interventions hold substantial potential to reverse many forms of age-related damage simultaneously and extend healthy lifespan beyond what can be achieved with conventional therapeutics. In this Perspective, we discuss recent insights, unmet needs, and emerging trajectories that are catalysing research and clinical development of replacement-based treatments and synergistic strategies for multi-targeted damage removal and export at the...

Although life expectancy has increased, many of the added years are lived in poor health, highlighting growing inequalities in ageing trajectories. Despite the increasing need for ageing-related health strategies, non-EU European countries remain underrepresented in comparative research, leaving limited evidence on healthy ageing disparities between EU and South-Eastern European (SEE) nations. This study explored variations in key health and socioeconomic indicators of societal ageing and...

Autoimmune diseases rise steeply with biological aging, reflecting progressive failure of immune regulation. Inherited chromosomally integrated human herpesvirus 6 (iciHHV-6) represents a unique lifelong viral exposure in which the viral genome is embedded within host telomeres, potentially altering leukocyte telomere length (LTL), a core biomarker of immune aging. Circulating metabolites may further modify these viral-telomeric interactions. We analyzed 156,927 UK Biobank participants free of...

CONCLUSION: Integrating multimodal neuroimaging with ML enhances diagnostic accuracy for AD and MCI and identifies potential neuroimaging biomarkers, providing objective evidence to support early clinical intervention.

ObjectivesObesity is common among older Black adults, but its underlying drivers, such as neighborhood racial composition (NRC), remain understudied. This study examined the association between NRC and obesity among older Black adults, evaluating the role of individual-level socioeconomic status (SES).MethodsData from the Nashville Stress and Health Study was linked to five-year estimates from the American Community Survey. Obesity was defined as body mass index ≥30 kg/m². NRC was measured with...

Chronological age predicts cancer survival but does not capture differences in biological aging rates. We apply FaceAge, an artificial intelligence algorithm that predicts biological age from a facial photograph, to serial clinical facial photographs to calculate the Face Aging Rate (FAR; change in FaceAge divided by the time between photographs). We analyze data from 2276 cancer patients receiving radiation therapy, using photographs captured during routine care. Higher FAR is associated with...

Reproductive aging is an increasing health concern that affects family planning and overall well-being. While extensively studied in females, the mechanisms driving male reproductive aging remain largely unexamined. Here, we found that mammalian Sirtuin 7 sustains spermatogenesis in an age-dependent manner. Sirtuin 7 deficiency in mice increases histone H3 lysine 36 acetylation in spermatogonia and spermatocytes, a pattern also observed during natural aging, and leads to altered chromatin...

Musculoskeletal pain and mobility disability are common in older adults, but relationships among pain parameters and physical performance are poorly understood. We quantified the impact of different pain measures-recalled and movement-evoked pain-on walk and stair climb time in older adults from the Study of Muscle, Mobility and Aging (SOMMA). In SOMMA (N = 879, age = 76.3 ± 5.0 years, 59% women, 84% non-Hispanic White), participants completed usual pace 400-m walk (avg = 6.6 ± 1.2 min) and...

Ageing-related diseases (ARDs) display diverse phenotypes yet share an age-dependent rise in incidence, suggesting mechanistic links with ageing processes. We examined whether ageing-related genes differ systematically from genes associated with multiple ARD clusters. Across 57 ARDs from UK Biobank, network analyses showed that ageing-related genes, although rarely ARD-associated, lie significantly closer to many ARDs through greater-than-chance proximity in protein-protein interaction (PPI) and...

T cell immunosenescence refers to the progressive functional decline of T lymphocytes with aging, characterized by the phenotypic markers, mitochondrial dysfunction, and the senescence-associated secretory phenotype (SASP), representing a pivotal aspect of overall immune aging. This review systematically elucidates the critical role of T cell immunosenescence in the pathogenesis of common inflammatory skin diseases, including psoriasis, atopic dermatitis, rosacea, and seborrheic dermatitis....

Sirtuin 1 (SIRT1) was initially identified as an enzyme that deacetylates histones and suppresses gene activity. Since then, its roles have expanded considerably, and it is now recognized as a multifunctional protein conserved across various organisms. Despite increasing interest, it remains essential to clarify how exercise-induced changes in SIRT1 counteract multiple hallmarks of aging, as well as the full scope of SIRT1's impact on different physiological systems. This review highlights...

Stress response pathways are emerging as conserved modulators of lifespan. The prevailing hypothesis is that activation of stress-responsive pathways, including the amino acid deprivation arm of the integrated stress response (ISR; the GCN2-ATF4 pathway), is prolongevity. Activation of ATF4 orthologs extends lifespan in Saccharomyces cerevisiae and Caenorhabditis elegans, but its role in other longer-lived organisms remains unclear. We comprehensively tested the role of the GCN2-ATF4 pathway in...
