'Death switch' protein complex found in Alzheimer's patients
Scientists in Germany and China have found a key protein complex, called NMDAR/TRPM4, that acts like a "death switch" and pushes Alzheimer's disease to get worse.
Their discovery, published in March 2026, could open up new ways to treat this tough brain condition.
The 'death switch'
The NMDAR/TRPM4 complex forms when two proteins connect at a spot known as "TwinF," creating a toxic combo that kills brain cells.
The team found way more of this complex in mice with Alzheimer's than in healthy ones, linking it directly to the disease's damage.
Promising drug
Researchers tested a drug called FP802 that blocks this harmful connection.
Mice with Alzheimer's given FP802 kept their memory and thinking skills better, and had less brain cell damage.
Even cooler, it seems FP802 might help protect against other diseases like ALS too, since they share similar protein issues.
