High-frequency repetitive transcranial magnetic stimulation upregulates BDNF expression and promotes synaptogenesis in mouse models of Parkinson's disease
Synaptic dysfunction exists before symptoms occur in Parkinson's disease, and restoring synaptic function as a promising therapeutic approach. Brain-derived neurotrophic factor serves as a key neuroregulatory factor in regulating synaptic function. Studies have shown that the protein levels of brain-derived neurotrophic factor is low in Parkinson's disease mice. However, repetitive transcranial magnetic stimulation (rTMS) can mitigate this decline. We explored the protective role of rTMS on...
Microglial STING is a central safeguard against neurological decline with age
Functional decline of the central nervous system (CNS) is driven by the breakdown of the blood-brain barrier (BBB) and attendant inflammation, all hallmarks of age-related neurodegeneration. Despite intense interest in how the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway impacts neurodegenerative processes in aging, its role in shaping these features of CNS fate during physiological aging remains unclear. Here, using physiologically aged mice, we uncovered an...
Latent Cognitive Profiles and Demographic Determinants in Older Adults without Dementia: A National Cross-Sectional Study
CONCLUSIONS AND IMPLICATIONS: About half of older adults exhibit domain-specific deficits, suggesting tailored interventions are essential. Profile 5 needs comprehensive strategies, whereas orientation-focused training could benefit profiles 2, 3, and 4. Demographic factors-particularly age, ethnicity, and income-should guide customization to enhance intervention participation and adherence.
"Aging and epigenetic implications in radiotherapy: The promise of BNCT"
Although cancer treatment strategies have made considerable progress in recent decades, the challenge of selectively killing tumor cells while minimizing damage to healthy tissue remains. Radiotherapy (RT) continues to be crucial for tumor growth control when combined with surgery, chemotherapy, and immunotherapy. RT effectiveness depends on factors such as cancer type, tumor features, and the choice of external or internal treatment. Given its non-invasive nature and low systemic toxicity, RT...
Cell-death pathways and tau-associated neuronal vulnerability in Alzheimer's disease
Neuronal loss is the ultimate driver of neural system dysfunction in Alzheimer's disease (AD). We used single-nucleus RNA sequencing and neuropathological phenotyping to elucidate mechanisms of neurodegeneration in AD by identifying vulnerable neuronal populations and probing for their differentially expressed genes. Evidenced by transcriptomic analyses and quantitative tau immunoassays of human AD and non-AD brain tissue, we identified a neuronal population especially vulnerable to tau...
Biomarkers of Cellular Senescence in Type 2 Diabetes Mellitus
Although animal studies have linked cellular senescence to the pathogenesis and complications of type 2 diabetes mellitus (T2DM), there is a paucity of corroborating data in humans. Thus, we measured a previously validated marker for senescent cell burden in humans, T-cell expression of p16 mRNA, along with additional biomarkers, to compare the senescence phenotypes of postmenopausal control (lean, N = 37) and T2DM (N = 27) participants. To control for effects of obesity alone, we included a...
