Pyroglutamate-modified amyloid-β (pE3-Aβ) is a highly pathogenic Aβ species that accumulates within amyloid plaques and contributes to aggregation, neuroinflammation and neuronal dysfunction in Alzheimer’s disease (AD). Researchers from Sound Biologics (Qilu Puget Sound Biotherapeutic Corp.) described the preclinical profile of PSB-229, a novel brain-shuttled anti-pE3-Aβ antibody in models of AD.
