Reframing menopause and menopause hormone therapy as opportunities for healthy aging

6 days 4 hours ago
Menopause is an important biological transition with up to 72 symptoms that shapes aging trajectories across organs and encompasses ~40% of the female lifespan. Although menopause awareness is increasing, research on strategies for menopause symptom management and optimizing health in the postmenopausal period is lacking. This Review highlights that menopause characteristics, such as type, timing, and symptom burden, influence health outcomes and later-life disease risk. Similarly, menopause...

Glucose-deprived tumor microenvironment activates AMP-activated protein kinase to drive adoptively transferred T helper 9 cell senescence

6 days 4 hours ago
T helper 9 (Th9) cells show promise for adoptive cell therapy (ACT) against solid tumors. However, clinical application faces challenges regarding their persistence in the tumor microenvironment (TME). We observed that tumor growth gradually reduced glucose concentrations in the TME, accompanied by a decline in transferred Th9 cells and their effector functions, due to Th9 cell senescence. Restoring glucose concentrations suppressed Th9 cell senescence, thereby improving their persistence....

Centenarians and oldest olds in Liguria - COOL: A multidisciplinary cohort study to investigate the genetic determinants of cognitive well-being in Genoa, Italy. Rationale, study protocol and baseline cohort profile

6 days 4 hours ago
CONCLUSIONS: We showed that the protocol is feasible and agreeable to participants and their families. A comprehensive phenotype dataset was established, and DNA samples were stored for subsequent genomic analysis. Centenarians exhibited a broad spectrum of cognitive profiles, from preserved cognition to severe dementia. Some data were unavailable, which should be considered in light of the study design and the characteristics of the cohort. These findings will eventually allow investigation of...

Peripheral-central interactions shape the decoupling between auditory brainstem response amplitudes and auditory thresholds during aging and noise exposure: a computational modeling study

6 days 4 hours ago
Age-related and noise-induced hearing loss reflect progressive cochlear degeneration and adaptive changes in central auditory pathways, yet their joint effects on auditory brainstem response (ABR) amplitudes and auditory thresholds remain unclear. We developed the Auditory Homeostatic Dynamics Model (AHDM), a three-state ordinary differential equation model of hair-cell sensory function, cochlear synaptic integrity, and activity-dependent central compensation across low-, mid-, and...

Ferroptosis-driven inflammaging in age-associated degenerative disorders: Molecular mechanisms and therapeutic potential of natural products

6 days 4 hours ago
Persistent low-grade inflammation, oxidative stress, cellular senescence, and disturbance of cellular homeostasis are all connected with ageing and can lead to the development of age-related diseases. Ferroptosis, an iron-dependent type of controlled cell death, has been linked to these processes more and more. It may represent a key connection between inflammation, oxidative damage, and tissue failure as people age. With a focus on neurodegenerative, cardiovascular, metabolic, pulmonary, and...

Alzheimer’s risk gene APOE4 may have a reversible weakness

6 days 9 hours ago
The Alzheimer’s risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in experiments, revealing promising new targets for Alzheimer’s, Parkinson’s, and other neurodegenerative diseases.
