Web10 de abr. de 2024 · Amyloid formation is a nucleation-dependent polymerization reaction [ 17 ]. Reactions of this type share an initial lag phase followed by an elongation phase where most of the “proper” fibril formation is observed. The reaction ends in a plateau indicating no further increase in amyloid fibrils. WebAn increasing amount of evidence suggests that in several amyloid diseases, the fibril formation in vivo and the mechanism of toxicity both involve membrane interactions. We …
