Study Suggests Treatments that Unleash Immune Cells in the Brain Could Help Combat Alzheimer’s Posted on April 25th, 2024 by Dr. Monica M. Bertagnolli In Alzheimer’s disease, a buildup of sticky amyloid proteins in the brain clump together to form plaques, causing damage that gradually leads to worsening dementia symptoms. A promising way to change the course of this disease is with treatments that clear away damaging amyloid plaques or stop them from forming in the first place. In fact, the Food and Drug Administration recently approved the first drug for early Alzheimer’s that moderately slows cognitive decline by reducing amyloid plaques. Still, more progress is needed to combat this devastating disease that as many as 6.7 million Americans were living with in 2023. Recent findings from a study in mice, supported in part by NIH and reported in Science Translational Medicine , offer another potential way to clear amyloid plaques in the brain. The key component of this strategy is using the brain’s built-in cleanup crew for amyloid plaques and other waste products: immune cells known as microglia that naturally help to limit the progression of Alzheimer’s. The findings suggest it may be possible to develop immunotherapies—treatments that use the body’s immune system to fight disease—to activate microglia in the brains of people with Alzheimer’s and clear amyloid plaques more effectively.
