Innovative approaches and challenges in antibody-based therapeutics for Alzheimer’s disease
Neurological conditions, such as Alzheimer’s disease (AD) and tau-related pathologies, represent a substantial worldwide health dilemma. This review explores recent advancements and challenges in single-domain antibody (VHH)-based strategies targeting beta-secretase 1 (BACE1) inhibition and tau-related therapeutics. The methodology adopted in this study involved a comprehensive search of databases (e.g., Scopus, PubMed, and Google Scholar), with recent articles cited to provide an up-to-date overview. The research examines the limitations of current AD treatments, emphasizing the need for innovative techniques. We, further, discuss potential gene transfer methods using adeno-associated virus-based vectors for central nervous system delivery of single-domain immunoglobins/antibodies (VHHs) to inhibit BACE1. In addition, insights into anti-tau therapeutics, including passive immunization and active vaccines, offer novel insights into research. These findings hold implications for the redesign of therapies for neurodegenerative disorders and the advancement of clinical understanding.
