For these peptides, cross-polymerization (fibrils of one polypeptide sequence causing other fibrils of another sequence to form) is observed in vitro and possibly in vivo.
Para estes péptidos a polimerización cruzada (fibrilas dunha secuencia polipeptídica que causan a formación doutras fibrilas doutra secuencia) obsérvase in vitro e posiblemente in vivo.
