Intranasal Delivery of BBB-Penetrating Antibody Conjugates
🧪 Overview
Develop intranasal formulations of anti-amyloid antibodies conjugated to brain-penetrating peptides, bypassing the BBB via olfactory and trigeminal nerve pathways. This could achieve direct CNS delivery while avoiding systemic circulation and associated side effects.
Debate provenance: derived from debate `sess_sda-2026-04-01-gap-008` on question: Anti-amyloid antibodies (lecanemab, donanemab) have ~0.1% brain penetrance. Engineering improved BBB transcytosis via transferrin receptor, LRP1, or novel shuttle peptides could dramatically improve efficacy.. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms APP, Antibody, BBB, BBB-Penetrating, CNS, Conjugates, Delivery, Intranasal. Novelty signal: skeptic-discussed-with-qualified-concession.
