Peroxisomes, key metabolic organelles, maintain metabolic homeostasis, yet their role in immune cells remains underexplored. While animal studies show age-related declines in peroxisome biogenesis, this process is unconfirmed in human aging. We investigated peroxisome biogenesis in human peripheral blood mononuclear cells (PBMCs) and found a significant decline in aged CD19+ B cells compared to CD4+ T cells, CD8+ T cells, and CD14+ monocytes. B cell aging also reduces peroxisomal matrix enzyme import, evidenced by decreased SKL-containing enzymes and mature ACOX1, alongside downregulation of PEX19 and E3 ubiquitin ligases PEX2, PEX10, and PEX12. These findings confirm an evolutionarily conserved and age-related decline in peroxisome biogenesis. Further, our work unveils cell type-specific changes in aging human PBMCs, and provides new insights into peroxisome-mediated immunometabolism and B cell aging.","PeriodicalId":22892,"journal":{"name":"The Journals of Gerontology Series A: Biological Sciences and Medical Sciences","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lung, as a complex organ, undergoes various microenvironmental changes during aging, which are crucial for lung function and the development of related diseases. Aging affects the pulmonary microenvironment in multiple ways, accelerating the decline in lung function. One of the key mechanisms of aging is cellular senescence, which refers to the state in which cells lose their ability to divide and function properly. Cellular senescence leads to a decline in the regenerative capacity of lung cells and may trigger inflammatory responses. Correspondingly, aging also affects the immune system, making the older adults more susceptible to respiratory infections. Moreover, intercellular communication within the pulmonary microenvironment changes during aging, potentially compromising lung structural integrity and function. Understanding these processes is essential for developing new therapeutic strategies to delay lung aging and improve pulmonary health in the older adults. This review focuses on the impact of aging on the pulmonary microenvironment, including changes in cellular senescence, alterations in immune responses, and the involved molecular mechanisms, aiming to provide insights for the diagnosis and treatment of age-related pulmonary diseases.","PeriodicalId":22892,"journal":{"name":"The Journals of Gerontology Series A: Biological Sciences and Medical Sciences","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test the hypothesis that lower oxidative capacity would yield greater non-oxidative ATP production, 19 young (10F) and 17 older (9F) adults performed knee extensor muscle contractions in a 3-tesla magnetic resonance system. Phosphorus metabolites were used to calculate oxidative capacity (rate constant of phosphocreatine recovery; k PCr, s-1) and estimate the maximal rate of oxidative ATP production (Vmax, mM·s-1) following a 24-s dynamic contraction protocol. Next, ATP production (mM·s-1) by the creatine kinase reaction (ATPCK), glycolysis (ATPGLY), and oxidative phosphorylation (ATPOX) was determined during 4 min of dynamic muscle contractions. Proton spectroscopy of deoxymyoglobin was also acquired in a subset (n = 12) and used to calculate the cytosolic partial pressure of oxygen (PO2). Young muscle had a greater k PCr (0.023±0.005s-1, mean±SD) than older muscle (0.020±0.003s-1, p = 0.033). ATPCK, ATPGLY, and ATPOX were not different by group (p ≥ 0.129), but ATPOX as %Vmax was lower in younger than older muscle (55±14%, 71±10%, respectively, p < 0.001). Intracellular oxygen availability (PO2) was not different by group (young: 2.4±0.7 Torr, n = 7; older: 3.2±1.6 Torr, n = 5, p = 0.371). These new findings suggest a bioenergetic rigidity in older muscle, such that it adapts to the energetic demand by using oxidative ATP production at a greater percentage of capacity rather than switching to an increased use of non-oxidative ATP production.","PeriodicalId":22892,"journal":{"name":"The Journals of Gerontology Series A: Biological Sciences and Medical Sciences","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To advance the understanding of this interrelationship, we sought to determine whether a mentally fatiguing task differentially effects hand grip motor function in older versus younger adults.METHODSYoung (n = 10, 33 ± 3 years) and older adults (n = 15, 69 ± 3 years) free of overt neurological disease and who did not report chronic fatigue symptoms participated in two testing sessions. During both sessions, participants had their composite grip strength (GS) and their multi-finger force deficit (MFFD) measured. The MFFD assays the degree of neural inactivation observed during a composite grip strength test. During one session participants completed a series of psychomotor vigilance tasks (PVT) to induce mental fatigue. The other session served as a control condition.RESULTSOlder adults exhibited an ∼18% reduction in composite GS associated with mental effort, which was significantly greater than that observed in young adults. Indirect neural activation, assessed via the MFFD, was reduced by approximately 22% in older adults during mental effort, which was significantly greater than the reduction observed in young adults.CONCLUSIONS: These findings indicate that mental exertion/fatigue results in decreased composite GS and increasing impairments in neural activation in older adults. No effect on indices of neuromuscular performance were observed in young adults. These findings suggest that neural mechanisms are heavily involved in the regulation of composite grip strength, and that the relative contribution of neural and muscular mechanisms of handgrip strength are state dependent in older adults.","PeriodicalId":22892,"journal":{"name":"The Journals of Gerontology Series A: Biological Sciences and Medical Sciences","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144504583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the impact of long-term disability on phenotypic and functional aging trajectories, and assess the role of key demographic and social determinants on those trajectories.METHODSData from the 2006-2020 waves of the Health and Retirement Study were used. Phenotypic aging was measured by the metabolic dysfunction risk score (MDRS) and functional aging was operationalized through limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL). Growth curve modeling was employed, adjusting for age, birth cohort, gender, race/ethnicity, and educational attainment.RESULTSA total of 7,234 were included in the analysis, comprising 873 PAwD and 6,361 individuals from the general population. Results suggested pronounced disparities in phenotypic and functional aging trajectories between groups, with compounded vulnerabilities among marginalized subgroups. PAwD exhibited significantly higher MDRS and ADL/IADL scores, with more rapid escalation over time, suggesting premature and accelerated aging. Racial/ethnic minorities and individuals with lower education faced intersecting disadvantages in both domains. Woman aging with disability exhibited marginally greater MDRS than men. Cohort-disability interaction revealed that older PAwD cohorts experienced steeper functional decline, while younger cohorts showed accelerated metabolic dysregulation.CONCLUSIONSThese findings highlight the imperative for inclusive public policies that address structural inequalities, particularly educational and racial disparities.

Methods Based on the China Health and Retirement Longitudinal Study, we enrolled 13745 participants in the final analysis. The living environmental score incorporated seven factors: ambient fine particulate matter, residential greenness, household fuel use, indoor temperature, water sources, building types, and household cleanliness (ranged from 0 to 8). Frailty was assessed by a 40-item deficit-accumulation frailty index. Cox proportional hazards regressions were used to assess the longitudinal associations of individual and joint exposure to living environmental factors with risk of frailty and mortality. Results In this prospective study, 3389 participants developed frailty and 815 died during a 7-year follow-up. A higher living environmental score was linked to reduced risks of frailty (hazard ratio (HR): 0.872, 95% CI: 0.854-0.890) and mortality (HR: 0.893, 95% CI: 0.856-0.932). Population-attributable fraction analyses revealed that 23.5% of frailty and 17.2% of deaths could be attributed to lower living environmental scores. For single factors, solid fuel use and PM2.5 exposure had the greatest attribution to incident frailty and all-cause mortality, respectively. The effects of low living environmental score on all-cause mortality were mediated via frailty. Conclusion Multiple living environmental risk factors were separately and jointly associated with increased risks of frailty and mortality in an additive manner, emphasizing the importance of comprehensively assessing various environmental factors to promote healthy aging.","PeriodicalId":22892,"journal":{"name":"The Journals of Gerontology Series A: Biological Sciences and Medical Sciences","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
