| Destruction of mitochondrial transmembrane potential, which is widely regarded as one of the earliest events in the process of cell apoptosis. Mitochondria are organelles within eukaryotic cells that produce adenosine triphosphate (ATP), the main energy molecule used by the cell. For this reason, the mitochondrion is sometimes referred to as “the powerhouse of the cell”. Mitochondria produce ATP through process of cellular respiration—specifically, aerobic respiration, which requires oxygen. The citric acid cycle, or Krebs cycle, takes place in the mitochondria. The mitochondrial membrane potential is widely used in assessing mitochondrial function as it relates to the mitochondrial capacity of ATP generation by oxidative phosphorylation. The mitochondrial membrane potential is a reliable indicator of mitochondrial health. In cancer cells, ΔΨm is often decreased, which can lead to changes in cellular metabolism, increased glycolysis, increased reactive oxygen species (ROS) production, and altered cell death pathways. The membrane of malignant mitochondria is hyperpolarized (−220 mV) in comparison to their healthy counterparts (−160 mV), which facilitates the penetration of positively charged molecules to the cancer cells mitochondria. The MMP is a critical indicator of mitochondrial function, directly reflecting the organelle's capacity to generate ATP through oxidative phosphorylation. |
| In Alzheimer's disease (AD), cholinergic dysfunction (often with reduced acetylcholine tone and impaired choline metabolism) is linked with cortical dysfunction, memory deficit, abnormal cerebral blood flow, task learning difficulty, sleep-cycle disruption, and neurodevelopmental effects (context-dependent). CORE HALLMARKS / HIGH-CONFIDENCE AXES: - tau and Aβ, their accumulation in AD brains is known to be a major hallmark. In AD, PP2A↓ activity is decreased (reported), contributing to hyperphosphorylated tau accumulation. SIRT-1↓ levels in AD brains are associated with accumulation of Aβ and tau (reported). - glucose metabolism↓ (brain glucose hypometabolism) occurs in AD long before significant clinical signs in many cohorts/models (reported). - Neuroinflammation / lipid mediator tone (reported): 5-LOX↑ and PGE2↑ (model-/region-dependent). - Synaptic vulnerability (reported): PSD95↓ in hippocampus and cortex; restoring PSD95 shows cognitive benefits in models. - Clearance/transport imbalance (reported): IDE↓, NEP↓, LRP1↓, and AEP↑ protein levels in AD brains (reported). COMMONLY REPORTED DIRECTIONAL CHANGES (model/region/compartment dependent): - Monoamines (reported): concentrations of 5-HTP↓, 5-HT(seratonin)↓, and 5-HIAA↓ are lower in Alzheimer's patients (varies by region/study). - Cholinergic system (clinical target): reduction in ACh↓ production; ChAT↓ activity reduced (synthesizes ACh). - Four key enzymes frequently targeted in AD symptom/adjunct strategies: AChE, BChE, MAOA, MAOB (objective inhibit). - Neurotrophic tone (reported): BDNF↓ in key regions. - Stress can decrease expression of brain-derived neurotrophic factor (BDNF). - Kinase/protease stress (reported): CDK5↑ hyperactivation; calpain↑ overactivated by increased intracellular Ca²⁺ → p-tau and aggregation. - Aβ-linked synaptic regulator (reported): STEP↑ upregulated largely due to Aβ oligomer accumulation. - α-secretase axis (reported): ADAM10↓ downregulated in AD brains. - Metabolic cofactors (reported): ALC↓ (ALCAR); Homocarnosine↓ (CSF declines with age); possible low Taurine↓ (age-related + dementia reports). - Ion/glutamate handling (reported): impaired glutamate clearance + depressed Na+/K+ ATPase → cellular ion imbalance risk. - Aging reduces NAD⁺↓ (in AD depletion may be more severe). - Mitochondrial capacity axis (reported): PGC-1↓ decreased in Alzheimer’s brains. - Innate immune DNA-sensing axis (animal): cGAS–STING↑ elevation observed in AD mice and normalized by NR treatment. - Vascular/structure (reported): a profound change in BBB permeability; progressive brain shrinkage (atrophy). - Glycation axis (reported): AGEs↑ and RAGE↑ expression. - cerebrospinal fluid (CSF) TMAO is higher in individuals with MCI and AD dementia compared to cognitively-unimpaired individuals. (gut microbes enzymatically generate trimethylamine (TMA) from choline or l-carnitine). HOMOCYSTEINE / B-VITAMIN AXIS: - Raised plasma total homocysteine (tHcy)↑ associated with cognitive impairment, AD, or vascular dementia (epidemiology). - Homocysteine can build up if vitamin B6, B12, or folate levels are low. - Homocysteine and B-vitamin in Cognitive Impairment (VITACOG) study. - Vit B6 might be an important B vitamin (often discussed along with B12 and folate). - Thiamine↓ deficiency produces a cholinergic deficit (well-aligned with AD features). - Decreased thiamine (B1) in AD may exacerbate Aβ deposition, tau hyperphosphorylation, and oxidative stress (reported). MICRONUTRIENTS / CAROTENOIDS (reported; compartment-dependent): - vitamin A↓ and β-carotene↓ lower in some AD cohorts; excess retinol may contribute to osteoporosis risk. - Diminished circulating vitamin E↓ reported in AD. - Vitamin B5↓ in multiple brain regions (reported). - Trace elements: patients with AD reported lower serum Se, Cu, and Zn↓ (serum findings vary by study). - Brain metals: some studies report higher brain copper↑ and iron↑ in specific regions/structures; compartment and region matter. Rosmarinic acid reported to reduce copper-induced neurotoxicity in vitro/in vivo and may interfere with amyloid–copper interactions (preclinical). - SAMe↓ concentrations in CSF reported in AD. - MPOD often reduced in AD patients. - AD brains reported lower levels of lutein↓, zeaxanthin↓, anhydrolutein↓, (VitA)retinol↓, lycopene↓, alpha-tocopherol↓. RISK CONTEXT: - Apolipoprotein E4 (ApoE4) genotype is the strongest known genetic risk factor for late-onset AD. - One copy of ApoE4: ~3–4× increased risk (range varies by cohort). - Two copies: ~8–12× increased risk (range varies). - VitK lower in circulating blood of APOE4 carriers (reported). - Type 2 diabetes, traumatic brain injury, stroke, diet, and above all, aging is the number ONE risk factor. Treatments / Strategy Targets (high-level): - Early intervention tends to have a greater positive effect than interventions during middle or late stages. - BOLD fMRI imaging can be used to observe brain activity via blood oxygen/flow changes. - Reduce ROS and inflammation in the brain (context-dependent; avoid over-suppressing adaptive signaling). - Inhibiting acetylcholinesterase (AChE) (which breaks down ACh), e.g., donepezil, rivastigmine. - Natural AChE inhibitors include: Berberine, Luteolin, Crocetin(saffron), Querctin, TQ - Natural AChE inhibitors in database (check BBB pass potential). - MAOB inhibitors, APP inhibitors, PGE2 inhibitors, NLRP3 inhibitors, BACE inhibitors - BDNF activators, PSD95 activator - STEP, ADAM10 - Diets with an adequate ratio (5:1) of omega-6:3 (Mediterranean diet). - Vitamins B1, B6, B12, B9 (folic acid) and D, choline, iron and iodine exert neuroprotective effects (general nutrition framing). - Antioxidants (vitamins C, E, A, zinc, selenium, lutein and zeaxanthin). - Fiber may promote gut microbiome diversity influencing brain health. - Supplementing with NAD⁺ precursors (NR or NMN) improves cognition and reduces amyloid/tau pathologies in AD mice (animal evidence). - "It is advisable to consume diets with an adequate ratio (5:1) of omega-6:3 fatty acids (Mediterranean diet) ... antioxidants ... role in oxidative stress ... cognition." Nutrition Strategies - Reduction of cognitive decline may be achieved by following a healthy dietary pattern limiting added sugars while maximizing fish, fruits, vegetables, nuts, seeds.
