Amyloid Beta Insights

Amyloid beta, traditionally viewed as a harmful plaque in Alzheimer's, may actually serve as a defense mechanism against pathogens like bacteria and viruses. Recent findings suggest that certain herpes viruses are more prevalent in Alzheimer's brains, prompting the formation of plaques to trap these microbes. However, while amyloid beta plays a protective role, its accumulation can eventually trigger inflammation and dementia, highlighting the need for careful management of amyloid-targeting treatments.
