Low-dose Aspirin Seen to Reduce Amyloid Aggregates in Mouse Brains, Study Shows
Treatment with low-dose aspirin was found to reduce the amount of brain amyloid aggregates that researchers believe are a hallmark of Alzheimer's disease, according to a mouse study. These findings may open new therapeutic doors to prevent memory loss in Alzheimer’s patients. The study, “Aspirin induces Lysosomal biogenesis and attenuates Amyloid plaque pathology in a mouse model of Alzheimer's disease via PPARα,” was published in The Journal of Neuroscience. Acetylsalicylic acid, commonly known as aspirin, is one of the most frequently used drugs to manage inflammation, pain, and fever, and it is widely used to treat cardiovascular diseases. Previous studies have evaluated its protective effect in different disorders such as Parkinson's disease. High-dose aspirin users were found to exhibit better maintenance of cognitive functions and had reduced incidence of Alzheimer’s disease. While these studies suggest that aspirin may prevent neurotoxicity, its mode of action is still not fully understood. Rush University Medical Center researchers found that by treating the brain cells of Alzheimer's mice with aspirin they were able to promote the production of new lysosomes, small vesicles essential for cellular waste destruction. More importantly, the cells were able to reduce the amount of amyloid plaques, which are a hallmark of Alzheimer’s disease. Next, the team treated mice genetically engineered to have Alzheimer’s disease with a low-dose regimen of aspirin taken orally for a month. The treatment was found to promote the production of lysosomes and to reduce amyloid plaques in the hippocampus of mice – the brain area that is highly affected in Alzheimer’s disease. These findings suggest that low-dose aspirin can boost the eff
