TLDR Dutasteride may help reduce brain plaque linked to Alzheimer's by affecting cell energy structures and waste removal.
In the study from 2008, researchers investigated the neuroprotective effects of 4-azasteroids, specifically focusing on dutasteride, which was found to inhibit the mitochondrial permeability transition pore and increase autophagosomal structures in human cell lines. The in vivo experiments showed a notable decrease in β-amyloid plaque load in a model for cerebral amyloidosis, suggesting a link between the release of neurotoxic peptides, mitochondrial apoptosis, and autophagy. This connection could have implications for understanding and potentially treating neurodegenerative diseases associated with amyloid plaque formation, such as Alzheimer's disease.
