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

Aloe Vera Polysaccharides as Therapeutic Agents: Benefits Versus Side Effects in Biomedical Applications
Aloe Vera Polysaccharides as Therapeutic Agents: Benefits Versus Side Effects in Biomedical Applications
Aloe Vera (Aloe barbadensis Miller), a historically revered medicinal plant, has garnered great scientific attention due to its polysaccharide-rich bioactive compounds with significant therapeutic potential. This review examines the role of Aloe Vera polysaccharides as therapeutic agents in biomedical applications, highlighting their benefits as well as the risks. Traditionally recognized for its anti-inflammatory and antimicrobial effects, which are very important in wound healing, the Aloe Vera relies on its polysaccharides, which confer immunomodulatory, antioxidant, and tissue-regenerative properties. These compounds have shown promise in various applications, including skin repair, tissue engineering scaffolds, and antiviral therapies, with their delivery being facilitated via gels, thin films, or oral formulations. This review explores also their mechanisms of action and applications in modern medicine, including in the development of topical gels, dietary supplements, and innovative delivery systems such as thin films and scaffolds. Despite the promising benefits, the review addresses the possible side effects too, including allergic reactions, gastrointestinal disorders, and drug interactions, emphasizing the importance of understanding these risks for their safe clinical use. Assessing both the advantages and challenges of Aloe Vera polysaccharide medical use, this review contributes to the ongoing dialog regarding the integration of natural products into therapeutic practices, ultimately supporting informed decisions regarding their clinical application.
