The liver is a major metabolic organ, responsible for synthesizing and breaking down diverse metabolites. Recently, the liver's immunological functions have gradually been unveiled: combating pathogens and maintaining tissue homeostasis. Age-related functional alterations in these immune cells emerge as potential drivers of hepatic dysfunction and age-associated pathologies. However, systematic investigations into spatiotemporal immune cell dynamics during liver aging remain limited. To address...

As the global population ages, cellular senescence contributes increasingly to the burden of age-related diseases. Hallmarks of this process include telomere shortening and loss of proteostasis, frequently linked to DNA damage-associated transcriptional stress. Although telomere dysfunction-induced foci (TIF) have been well documented in lungs from patients with idiopathic pulmonary fibrosis (IPF), their occurrence and role during physiological lung aging remain unclear. Analysis of senescence...

Skeletal muscle mass and force decline with age, and the loss of muscle force precedes muscle atrophy. However, the underlying mechanisms remain unclear. Here, we investigated the role of the myosin co-chaperone, uncoordinated mutant number-45 myosin chaperone B (UNC45B), in regulating muscle mass and force. UNC45B expression decreased in mouse gastrocnemius muscle with age, particularly at 24 months old, and adeno-associated virus vector-mediated knockdown of Unc45b in 3-month-old mouse triceps...

The aggregation of amyloid proteins into fibrillar and oligomeric aggregates is linked to a number of neurodegenerative diseases. While the disease onset remains elusive in many cases, an understanding of the driving forces for the aggregation may help finding possible causes. While effects on amyloid formation kinetics are more commonly studied, gaining insights into these driving forces require a thermodynamic approach with equilibrium measurements. Here we investigate the temperature...

Embodied accounts of morality propose that corporeal self-awareness helps restrain immoral actions. The Sense of Agency (SoA)-the feeling of controlling one's actions and their consequences-drops when individuals harm others. However, whether modulating SoA shifts moral behavior remains unclear. Parkinson's Disease (PD) offers a unique model to address this question, because dopaminergic dysfunction affects both SoA and moral decision-making. We tested 23 individuals with PD in ON and OFF...

Alendronate effectively inhibits osteoclastic bone resorption and is considered as first line treatment of osteoporosis. Additionally, several studies suggest a beneficial effect on mortality that goes beyond life-extending effects attributed to the well-established fracture risk reduction. However, mechanisms of the mortality reducing effect of bisphosphonates are unclear. The turquoise killifish Nothobranchius furzeri (N. furzeri), a well-known model of accelerated aging, exhibits an extremely...
