A new paper published in the Journal Nature Communications Biology investigates the link between exposure to Harmful Algal Bloom neurotoxins and the development of Alzheimer's disease signatures in the brain transcriptome of stranded common bottlenose dolphins found in Florida's Indian River Lagoon. They essentially correlated changes in the dolphin brains’ DNA to chronic and acute exposure to blue green algae blooms. Dolphins serve as a "sentinel species" for Alzheimer’s Diseased because they live so long and can naturally develop Alzheimer’s-like neuropathological changes with age.
