Groundbreaking Discovery: Key to Stopping Alzheimer’s Brain Damage Revealed by Scientists

Researchers at KU Leuven and VIB discovered a process called necroptosis that causes nerve cell death in Alzheimer’s disease. They used specific inhibitors to stop this cell loss and improve memory in mouse models, suggesting new treatment options beyond targeting amyloid plaques.

Alzheimer’s disease leads to memory loss and cognitive decline, affecting over 55 million people globally. It is marked by the buildup of amyloid-beta plaques and tau tangles in the brain, which disrupt communication between cells and cause widespread nerve cell death.

Current treatments mostly manage symptoms. Recently approved drugs targeting amyloid plaques have not proven effective in improving cognition and memory. This highlights the need to prevent nerve cell death to address cognitive impairment in Alzheimer’s patients.

In a study published in Science Translational Medicine, researchers demonstrated that inhibiting necroptosis can prevent nerve cell loss in mouse models. Necroptosis drives cell death in Alzheimer’s, especially in cases with tau tangles.

The study showed that necroptosis is not activated in mice with only amyloid plaques. Inhibitors that block necroptosis improved social recognition memory in treated mice.

The researchers recommend further investigation of necroptosis inhibition as a treatment strategy for Alzheimer’s, complementing existing therapies aimed at amyloid and tau proteins.
