Background
Aβ peptides can be further modified by amino-terminal truncation that exposes a free glutamate residue to the enzyme glutaminyl cyclase, which catalyzes the formation of an amino-terminal pyroglutamate (pE) (7,8). Aβ (pE3) peptides exhibit increased stability relative to non-modified peptides due to an enhanced resistance to peptidase-mediated degradation (9) and a higher propensity to form β-sheets and aggregate (10). Antibodies targeting Aβ (pE3) peptides may be plaque-specific as there is no evidence for circulating Aβ (pE3) peptides (11).
