Optimizing Antibody-Based Therapies for Alzheimer's Disease: From Clinical Limitations to Molecular Engineering Innovations
Liu Q, Lin RR.. Aging and disease, 2026-06-04
Topic: Amyloid, tau and blood-test diagnosis
Antibody-based immunotherapy represents one of the most promising disease-modifying strategies for Alzheimer's disease (AD). Recent anti-amyloid-β (Aβ) antibodies have achieved robust plaque clearance and modest cognitive benefits in early AD, establishing clinical proof of concept. However, limited efficacy and safety concerns, particularly amyloid-related imaging abnormalities (ARIA), continue to restrict their therapeutic potential. This review outlines the current clinical status of antibody therapies targeting Aβ, tau, and neuroinflammatory pathways, and summarizes key antibody optimization strategies, including aggregation-state-selective targeting, Fc engineering, brain shuttle technologies, nanobody platforms, and nanotechnology-enabled delivery. We further discuss emerging concepts from tumor immunotherapy, such as antibody-guided protein degradation and conditionally active biologics, as potential avenues for next-generation AD treatment.

How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 25 of the 58 points we could judge it on, which is 43 out of 100.
