But in patients with Alzheimer's disease, amyloid-beta builds up and aggregates in the spaces between the brain's cells, instead of being cleared away  like it's supposed to be, and it's this buildup of amyloid-beta that's thought to be one of the key steps in the development of that terrible disease.
Ali kod oboljelih od Alzheimera, amyloid-beta nakuplja se u prostorima između stanica mozga, umjesto da se čisti na način na koji  bi trebao, a baš je to nakupljanje amyloid-bete navodno jedan od ključnih koraka u razvijanju ove strašne bolesti.
