Abstract Alzheimer’s disease is a neurodegenerative disorder and characterized by amyloid beta accumulation, synaptic dysfunction, oxidative stress, lacks effective therapies. Caloric restriction mimetics such as fisetin chlorogenic acid, natural polyphenols with antioxidant autophagy-inducing properties, show promise in mitigating age-related diseases. This study investigates their neuroprotective effects against induced toxicity differentiated human neuroblastoma SHSY5Y cells. Amyloid exposure disrupted redox homeostasis, impaired autophagy, mitochondrial exacerbating neuronal degeneration. Fisetin acid treatments reversed these deleterious restoring balance, suppressing reactive oxygen species upregulating critical enzymes like SOD1, GSR, catalase. These compounds also attenuated mitophagy via reduced PINK1 expression restored fusion Mfn2. Autophagy-related pathways were significantly modulated, evidenced increased AMPK decreased mTOR mRNA levels, alongside elevated of ATG101, ATG13, ULK1, P62 ATG5 levels. Docking studies revealed binding CGA within the pockets FKBP12 supporting interaction. Furthermore, improved integrity PSD95 synaptophysin reducing acetylcholinesterase expression. findings highlight potential ameliorating through autophagy activation, preservation, function enhancement. While this demonstrates transcriptional impact affinities caloric further translational biophysical analyses are required to elucidate mechanisms confirm therapeutic viability. research underscores agents, offering promising avenues for combating related neuropathies.

Abstract Oxidative stress plays a crucial role in organ aging and related diseases, yet the endogenous regulators involved remain largely unknown. This work highlights importance of metabolic homeostasis protecting against oxidative large intestine. By developing low-input user-friendly pipeline for simultaneous profiling five distinct cysteine (Cys) states, including free SH, total Cys oxidation (Sto), sulfenic acid (SOH), S -nitrosylation (SNO), -glutathionylation (SSG), we shed light on redox modification stoichiometries signaling with regional resolution gut monkeys. Notably, proteins modified by SOH SSG were associated primarily cell adhesion. In contrast, SNO-modified immunity. Interestingly, observed that Sto levels ranged from 0.97% to 99.88%, exhibiting two peaks increasing age. Crosstalk analysis revealed numerous age-related metabolites potentially modulating modifications. elucidated fumarate alleviating intestinal dextran sulfate sodium (DSS)-induced colitis mouse model. Our findings showed treatment promotes recovery several types, pathways, genes regulation. Calorie restriction (CR) is known strategy stress.

The gut microbiota (GM) produces various molecules that regulate the physiological functionality of brain through gut-brain axis (GBA). Studies suggest alteration in GBA may lead to onset and progression neurological dysfunctions. Moreover, aging is one prominent causes contribute GBA. With age, GM undergoes a shift population size species microflora leading changes their secreted metabolites. These also hamper communications among HPA (hypothalamic-pituitary-adrenal), ENS (enteric nervous system), ANS (autonomic system). A therapeutic intervention has recently gained attention improving health maintaining communication between calorie restriction (CR), which plays critical role autophagy neurogenesis processes. However, its strict regime lifelong commitment pose challenges. need produce similar beneficial effects CR without having rigorous compliance. This led an exploration mimetics (CRMs) could mimic CR's functions limiting diet, providing long-term benefits. CRMs ensure efficient functioning bacteria metabolites i.e., short-chain fatty acids, bile neurotransmitters. particularly for elderly individuals, as deteriorates with age body's ability digest toxic accumulates declines. In this review, we have explored effect extending lifespan by enhancing on metabolite production, conditions, dysfunctions including neurodegenerative disorders.

Aging, an inevitable physiological process leading to a progressive decline in bodily functions, has been abundantly researched domain with studies attempting slow it down and reduce its debilitating effects. Investigations into the cellular molecular pathways associated aging have allowed formulation of therapeutic strategies. Of these, caloric restriction (CR) implicated for role promoting healthy by modulating key targets like Insulin/IGF-1, mTOR, sirtuins. However, CR requires dedication commitment strict regimen which poses difficulty maintaining consistency. To maneuver around cumbersome diets, Caloric Restriction Mimetics (CRMs) emerged as promising alternatives mimicking beneficial effects CR. This review elucidates foundations enabling CRMs rapamycin, metformin, resveratrol, spermidine, many more function suitable anti-aging molecules. Moreover, explores clinical trials (retrieved from clinicaltrials.gov database) aimed at demonstrating efficacy effective candidates against age-related neurodegenerative diseases such Alzheimer's disease Parkinson's disease.

Intermittent fasting (IF) has demonstrated extensive health benefits through the regulation of fatty acid metabolism and modulation neuroimmune microenvironment, primarily via activation key signaling pathways such as AMP-activated protein kinase (AMPK) sirtuin 1 (SIRT1). IF not only facilitates oxidation improves metabolic health, but also enhances mitochondrial function, mitigates oxidative stress, promotes autophagy, inhibits apoptosis ferroptosis. These mechanisms contribute to its substantial preventive therapeutic potential in various conditions, including neurodegenerative disorders Alzheimer’s Parkinson’s diseases, autoimmune neurotraumatic conditions. While supportive evidence been obtained from animal models preliminary clinical studies, further large-scale, long-term randomized controlled trials are imperative establish safety evaluate efficacy comprehensively.

ABSTRACT Caloric restriction mimetics mimic the beneficial effects of dietary approaches, such as caloric without limiting intake. Chlorogenic acid (CGA) acts a mimetic; however, its neuroprotective mechanisms remain ambiguous. Therefore, in this study, we aimed to elucidate CGA on SH‐SY5Y cells treated with amyloid‐beta (Aβ)1‐42. Aβ1‐42 (1.25 μM) induced oxidative stress by significantly increasing pro‐oxidant levels and decreasing antioxidant cells. Additionally, it decreased Na + /K ‐ATPase Ca 2+ ion transporter activities enhanced acetylcholinesterase activity. However, (100 reversed these Aβ1‐42‐induced changes Overall, exerted against impaired activities, serving promising therapeutic candidate for neurodegenerative diseases, Alzheimer's disease.
