WebInhaled anesthetics should, therefore, favor amyloid β and similar peptide oligomerization if cavities exist at the intermolecular interfaces. And the stable, insoluble nature of the fibrillar oligomer suggests that the predicted enhancement of kinetics should result in a stable pool of oligomerized material rather than only a transient effect.
