Summary: Alzheimer's disease is a devastating neurodegenerative disorder characterized by initial memory impairments that progress to dementia. Synaptic dysfunction and loss have been established as the pathological features that best correlate with the typical early cognitive decline in this disease.

Summary: This study reveals that TPC2 can selectively increase its permeability to calcium ions when co-activated by the endogenous ligands NAADP and PI(3,5)P-2. This finding indicates that the flux of different ions through the same channel can be independently controlled and identifies TPC2 as a potential coincidence detector that optimizes lysosomal calcium signaling.

Summary: Alzheimer's disease, characterized by disrupted circadian rhythm and retinal pathology, is more prevalent in female individuals. The study found severe circadian rhythm disturbances and retinal pathological hallmarks in female APP/PS1 mice, along with A beta deposits in retinal layers. Reduced expression of aquaporins in the retinal tissue suggests that abnormal A beta transport contributes to retinal degeneration in the early stages of AD.

Summary: The study aims to investigate the pathological interaction between amyloidosis and tauopathy in Alzheimer's disease, and found that the development of tauopathy is exacerbated by the presence of newly forming amyloid deposits in younger brains and mature deposits in older brains.

Summary: Cardiovascular diseases pose a significant threat to human health, but drug development is time-consuming and costly. Researchers have developed a drug assessment platform based on an electrical-mechanical synchronized biosensing system, which allows for high-throughput and time-dependent assessment. The system can record and analyze dynamic responses of cardiomyocytes to drugs, enabling rapid and effective drug screening.

Summary: Increased astrocytic Ca2+ signaling has been observed in Alzheimer's disease mouse models. In this study, we investigated behaviorally induced astrocytic Ca2+ signaling in plaque-bearing mice and found an attenuated response to locomotion and a decoupling of pupil responses and astrocytic Ca2+ signaling. We also observed reduced norepinephrine signaling during spontaneous running and startle responses in the transgenic mice, providing a possible mechanistic explanation for the reduced astrocytic Ca2+ responses. Our findings suggest a dysfunction in the norepinephrine-astrocyte Ca2+ activity axis, which may contribute to cognitive deficits in Alzheimer's disease.

Summary: Increasing evidence supports the interaction of age, APOE, and sex in modulating Alzheimer's disease risk. Female APOE4 mice have the highest levels of Aβ deposition, fibrillar amyloid deposits, neuroinflammation, and earlier behavior deficits. The combination of female sex and APOE4 genotype may be the most detrimental for Alzheimer's disease.

Summary: This study aimed to evaluate the accuracy and reproducibility of two freely available segmentation algorithms for WMHs. A harmonized MRI protocol was implemented in 3T scanners across 13 European sites, with each site scanning volunteers twice to assess the difference between automated and manual segmentations, as well as the reproducibility between test and retest scans. The results showed that the LST algorithms exhibited moderate accuracy and good reproducibility, making them reliable tools for cross-sectional and longitudinal studies in multi-site settings.

Summary: This study examined the age-related changes in brain function and baseline brain structure that support motor skill acquisition. The findings showed that older adults experienced decreases in functional connectivity during motor skill acquisition, while younger adults experienced increases. Additionally, regardless of age group, lower baseline microstructure in a frontoparietal tract was associated with slower motor skill acquisition.

Summary: Physical exercise has a positive impact on hippocampal memory decline with aging. Recent studies have shown that even light exercise can improve memory and this improvement is mediated by the ascending arousal system. This study aimed to investigate the effects of light-intensity exercise on hippocampal memory function in healthy older adults and found that pupil dilation during exercise played a role in the memory improvement.

Summary: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by memory and functional impairments. This study analyzed participants from the Alzheimer's Disease Neuroimaging Initiative and found differential associations between cerebral spinal fluid (CSF)/neuroimaging biomarkers and cognitive/functional outcomes, as well as variations between sexes. These findings suggest that sex differences may play a role in the development of AD.

Summary: This study investigated the effects of age on the robustness and resilience of auditory system using the desert locust. The researchers found that gene expression changes were mainly influenced by age rather than noise exposure. Both young and aged locusts were able to recover their auditory nerve function within 48 hours of noise exposure, but the recovery of transduction current magnitude was impaired in aged locusts. Key genes responsible for robustness to noise exposure in young locusts and potential candidates for compensatory mechanisms in auditory neurons of aged locusts were identified.
