Cross-species characterisation of microglial morphology and proliferation during ageing
By 2050, one-fifth of the world is expected to be over 60, and the prevalence of age-related neurological conditions is predicted to increase dramatically. Aged animals are currently underutilised in neurological research, leading to a gap in knowledge about the contribution of biological age to the pathophysiology of age-related neurological conditions. Additionally, it is unclear whether age-related changes differ across species used in preclinical models, and how these differences may compare...
The 'mitochondrial guardian' α-amyrin links colourful fruit consumption to cognitive resilience
Mitochondrial quality control is essential for maintaining neuronal function and resilience during aging, yet pharmacological strategies that effectively restore mitophagy to maintain mitochondrial homeostasis remain limited. Emerging evidence suggests that dietary molecules may influence mitochondrial health, although the underlying mechanisms are largely unknown. Here, we summarize our recent finding whereby we have identified a robust mitophagy inducer: α-amyrin (αA). This molecule is a...
Volunteer Leadership in Older Adults' Self-Guided Learning Groups in Taiwan: Motivations and Management Processes Through an Ecological Lens
As global populations age, active aging and lifelong learning have become critical policy objectives. In Taiwan, the Ministry of Education (MOE) promotes Older Adults' Self-Guided Learning Groups (OASLGs); however, the sustainability of these groups relies heavily on volunteer leaders. This study investigates the motivations and management processes of "Excellent Leaders" in OASLGs using a qualitative approach. Drawing on Bronfenbrenner's ecological systems theory, we analyzed semistructured...

Organelle interactome disruption: The systemic pathological mechanisms and therapeutic prospects of mitochondria-lysosome-ER crosstalk in Alzheimer's disease
The traditional pathological framework of Alzheimer's disease (AD) primarily focuses on the accumulation of β-amyloid (Aβ) and tau proteins. However, therapeutic strategies targeting these molecules have repeatedly encountered setbacks in clinical translation. Recent studies have progressively revealed that the dynamic interaction network among intracellular organelles plays a central role in the pathogenesis of AD. This systematic review examines the independent dysfunctions of three key...
