It's called beta amyloid—it doesn't matter whether you remember the name or not—and it's a normal protein. We all have it in our brains, but in Alzheimer's disease the concentration of this protein goes up, and as it goes up, the molecules start to stick together until enough of them stick together and they deposit down as a plaque.
Il s'agit d'une protéine normale, présente dans tous les cerveaux; mais dans le cas de la maladie d'Alzheimer, sa concentration augmente et augmente jusqu'à ce que les molécules commencent à s'agglutiner et finissent par se déposer en plaques.
