There is an urgent need to identify interventions that broadly target aging-related cognitive decline and progression Alzheimer’s disease (AD). Bottlenose dolphins (Tursiops truncatus) have histologic changes similar AD in humans, they also develop shared age-associated co-morbidities identified as risk factors for including type 2 diabetes, ferroptosis, iron overload, which can be driven by nutritional C15:0 deficiency. We hypothesized (1) would amyloid beta (Aβ) plaques neuroinflammation paralleled of humans relation age-related progression, quantitative concentration, brain region; (2) dose-dependent activities relevant protecting health. Quantitative immunohistochemistry staining was used assess 68 tissues from archived brains 19 Navy evaluate associations among region, sex, age group. Further, activities, using a third-party panel intended screen potential therapeutics, were evaluated. Similar had the highest Aβ plaque density variation hippocampus (90th percentile 4.95 plaques/mm2), where increased with (p = 0.05). All measured markers detected, concentrations activated microglia (CD68+) (0.46 ± 0.38 cells/mm2). inhibitor two targets, fatty acid amide hydrolase (FAAH) (IC50 2.5 µM, 89% maximum inhibition at 50 µM relative URB597) monoamine oxidase B (MAO-B) 19.4 70% R(-)-Deprenyl). These demonstrated efficacy against formation neuroinflammation, protection function hippocampus. findings suggest that, addition co-morbidities, may play distinct role supporting health, especially higher concentrations.
