Beta amyloid, he thinks, is one of many things that can stress cellular garbage disposal in the brain. One of these things is tau, another protein used in cells to hold open channels so they can receive nutrients. When tau misbehaves, it clumps together, and the cells can’t get the food they need. What’s more, once the tau’s gone bad in one area of the brain, there’s a runaway chain reaction in the brain. Slowly, more and more of the tau goes bad, until a patient has Alzheimer’s disease.
