The glymphatic system was initially considered as a perivascular channel, responsible for the clearance of substances within the brain. With the deepening comprehension of the functions of the extracellular space (ECS) and the discovery of meningeal lymphatic vessels and subarachnoid lymphatic-like membrane, it is proposed that the glymphatic system should be a complex system encompassing the perivascular space, ECS, and lymphatic-like structures, and it plays crucial roles in the delivery of...

Parkinson's disease (PD), the second most prevalent neurodegenerative disorder, is marked by dopaminergic neuron loss and α-synuclein aggregation. Although Braak staging based on Lewy body pathology stratifies disease progression, clinical variability persists. Identifying stage-specific molecular signatures is essential for developing effective progressive biomarkers. Here, we integrated midbrain transcriptomic data from microarray, bulk RNA-seq, and snRNA-seq platforms. Subsequently, to...

Biological age is an important indicator of organ functions and health. Although mammograms are widely used in breast cancer screening, the potential of mammogram-based biological age predictors remains underexplored. Here, we propose a deep learning model to estimate the biological age of the breast using healthy mammograms. The model is developed on three large datasets and externally validated on two additional datasets, encompassing 95,826 mammograms from 44,497 women aged 18 to 98 years. It...

The cell cycle is a key regulator of endothelial cell specification into tip and stalk cell phenotypes, which are essential for angiogenesis in both normal development and pathological conditions. While the tumor suppressor p53 is known to regulate the cell cycle and influence cell fate, its role in modulating the cell fate of these phenotypes remains unclear. Using non-genotoxic small molecule and stapled peptide compounds to pharmacologically activate p53 via MDM2 inhibition, we demonstrate...

Mobility impairments from aging, injury, or medical conditions limit independence and social participation. Conventional assistive devices lack adaptability in complex environments. Recent wearable technologies integrating neural sensing, electronics, and co-design offer personalized, responsive mobility support. This perspective focuses on advances in wearable sensing and multimodal fusion for intent recognition, environmental interaction, and adaptive control in exoskeletons, prosthetics,...

Chaperone-mediated autophagy (CMA), once considered a secondary or auxiliary degradation pathway, is now recognized as a central regulator of synaptic proteostasis. A recent study by Khawaja et al. (2025) in Nature Cell Biology provides compelling evidence that CMA actively remodels the synaptic proteome in a sex-specific manner. Using a conditional knockout strategy based on Lamp2a-floxed mice crossed with a Camk2a-Cre driver line to achieve excitatory neuron-specific deletion of Lamp2a in...

Parkinson's disease (PD) is a common neurodegenerative disorder with a rising incidence in aging populations, substantially diminishing patients' quality of life. Mitochondria are central to neuronal energy metabolism, and mitophagy plays a pivotal role in maintaining mitochondrial quality by removing damaged organelles. In PD, impaired mitophagy leads to the accumulation of dysfunctional mitochondria, exacerbating oxidative stress and bioenergetic deficits and thereby accelerating disease...

CONCLUSION: Therefore, it is urgent to enhance digital skills and internet use among older populations to promote healthy aging.

The rapid increase in the global aging population presents significant psychosocial and economic challenges, especially in underdeveloped nations. This study examines the experiences of elderly retired government employees (65+) in Debre Tabor Metropolitan City, Ethiopia, using a qualitative hermeneutical phenomenological approach. Structured interviews with 15 participants revealed key issues affecting their well-being. Findings show severe isolation and loneliness, with many feeling abandoned...

Immunosenescence, a recognized hallmark of aging, is characterized by imbalances in immunocyte populations and a state of chronic inflammation. However, the tissue-specific dynamics of these changes and their potential as predictive biomarkers for aging remain poorly characterized. In this study, we established a multi-tissue immunological signature as a robust predictor of biological age by integrating immunocyte and cytokine profiling. Using Sprague-Dawley (SD) rats from five age groups (1-12...

Myostatin and follistatin are the regulators of muscle growth and pivotal proteins that regulate muscle tissue function. An integrated approach is HIIT and resistance training provides a holistic strategy for promoting healthy aging and maintaining functional abilities, potentially through the modulation of myostatin and follistatin levels. This study aims to assess the effect of high-intensity interval training and resistance training on myostatin and follistatin protein concentrations in aged...

HIV infection induces chronic immune activation, predisposing people living with HIV (PLWH) to early immunosenescence. It is essential to understand the mechanisms behind the senescence-associated secretory phenotype (SASP). This study investigates the role of extracellular vesicles (EVs) in peripheral immunosenescence in HIV infection associated with SASP modulation. Biological and in silico analyses were performed to explore the crosstalk between EVs, miR-21-5p, and SASP. Plasma EVs from PLWH...
