“…1,2 Despite the lack of structural or functional similarity amongst the 24 human amyloidogenic proteins, the process of amyloidogenesis results in the formation of a similar bundled cross-beta sheet assembly referred to as amyloid. The process of amyloidogenesis commences when conditions disfavor the native structure of an amyloidogenic protein or the soluble monomeric ensemble of conformations typically adopted by peptides.…”

“…Desde un enfoque estructural, las proteínas presentes en este tipo de organizaciones se caracterizan por tener plegamiento del tipo β, favoreciendo la hidrofobicidad y la agregación en estructuras específicas denominadas hoja β-plegada 1,5 . Esta disposición conformacional, confiere a las proteí-nas resistencia a proteólisis, desnaturalización y a mecanismos generales de eliminación presentes en la célula.…”

“…fase en este proceso (o fase exponencial), donde el reclutamiento exponencial de nuevas unidades a los agregados previamente formados, resulta en una gran carga de estructuras amiloides, las cuales se distribuyen en un amplio espectro de organizaciones como pequeños oligómeros, protofibras, fibras y, en algunos casos, placas amiloides 5,8 . A pesar de la relación existente entre este tipo de agregados y el desarrollo de la enfermedad, los mecanismos por los que se produce el típico daño celular en estas patologías es aún un tema controvertido.…”

“…Generally these materials are stained to a shade of red, however, it is noted by Blake et al [8] and Costa [14:2] that, when viewed in polarised light, Congo Red stains amyloid fibrils green. Significantly though, Congo Red only binds to proteins in alkaline (particularly for amyloid) and acid buffer conditions [34(pH3.5),27(pH2e4)], so at a neutral pH starch and cellulose alone will be stained.…”
