In rodent studies, chronic immobilization stress (CIS) is commonly used to investigate the neuropsychological effects of prolonged stress, leading to behaviours such as anhedonia, anxiety, and depressive-like symptoms. An enriched environment (EE) provides physical, cognitive, and sensory stimulation, which promotes social interaction, supports brain development, and can enhance the effectiveness of pharmacological treatments, improving overall therapeutic outcomes. Metformin, commonly prescribed for type 2 diabetes, has antidiabetic effects and helps reduce oxidative stress, inflammation, and cell death in the brain, which may contribute to its neuroprotective properties. This study aims to evaluate the effectiveness of metformin, an enriched environment (EE), and its combination in alleviating anxiety and depression-like behaviours, memory impairments, and metabolic changes.</p><p><strong>Materials and methods: </strong>Rats were exposed to chronic immobilization stress (CIS) for 2 hours per day over a period of 10 days, followed by 14 days of treatment with metformin (200 mg/kg) and 6 hours of daily exposure to an enriched environment (EE). Behavioural tests, including the open field test (OFT), elevated plus maze (EPM), sucrose preference test (SPT), and novel object recognition test (NORT), were conducted.

First, the analysis of amyloid biomarkers and stable-isotope label kinetics (SILK) studies indicate a correlation between AD diagnosis and heightened cellular uptake of beta-amyloid. Since beta-amyloid must be taken up by cells to become toxic, its uptake rate correlates with neurodegeneration. Also, aggregation seeds cannot form extracellularly due to low beta-amyloid levels in interstitial fluid but can develop inside lysosomes. Consequently, the density of extracellular aggregates correlates positively with cellular amyloid uptake rate. The model, which ties both beta-amyloid cytotoxicity and aggregation to cellular uptake, accurately predicts AD diagnosis patterns in the population. Second, beta-amyloid enters cells through endocytosis. Endocytosed beta-amyloid induces lysosomal permeabilization that occurs without plasma membrane damage and explains intracellular ion disturbances (including calcium overload) after exposure to extracellular beta-amyloid. The permeabilization is caused by channels formed in lysosomal membranes by some amyloid fragments produced by proteolysis of full-length beta-amyloid. Some membrane channels are large enough to leak cathepsins to the cytoplasm, causing necrosis or apoptosis. Also, local spikes of calcium cytosolic concentration due to calcium leakage from lysosomes can activate calpains, contributing to cell death. In surviving cells, accumulation of damaged lysosomes results in autophagy failure and slow mitochondrial recycling, promoting the production of reactive oxygen species and further cell damage. In this framework, AD's etiology is the membrane channel formation by amyloid fragments produced in lysosomes. The pathogenesis includes lysosomal permeabilization and the appearance of activated proteases in the cytoplasm. The correlation between AD diagnosis and the density of amyloid aggregates occurs because both amyloid cytotoxicity and extracellular aggregate formation stem from cellular amyloid uptake. To reflect key processes, we call this framework the Amyloid Degradation Toxicity Hypothesis of Alzheimer's Disease. It explains various phenomena and paradoxes associated with AD pathobiology across molecular, cellular, and biomarker levels. The hypothesis also highlights the limitations of current AD biomarkers and suggests new diagnostic and prognostic tools based on disease pathogenesis. Additionally, the framework identifies potential pharmacological targets for preventing disease progression.</p>","PeriodicalId":94309,"journal":{"name":"Current Alzheimer research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144060801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A balanced diet acts as a source of all essential nutrients that can facilitate the functioning of the brain, promote cognitive longevity, safeguard against neurodegeneration, and, accordingly, reduce the risk of AD. Despite the availability of conclusive evidence highlighting the role of nutrition in the prevention of AD, a range of concerns have been identified that limit dietary adherence and public health efforts. This calls for the need to adopt a multipronged approach, including interventions targeting policy-level changes, the education sector, improvement in the food systems, and behavioural modifications to encourage long-term adherence to diets that are healthy for the brain. In conclusion, diet plays a crucial role in Alzheimer's disease, and there arises the need to incorporate food items that are healthy for the brain to maintain cognitive health and reduce the overall risk.
