Summary
Antibody therapeutics face a plateau due to systemic administration issues. This review proposes Antibody-Carrier Integrated Systems (ACIS) for targeted drug delivery, enhancing precision medicine.
Area of Science:
- Biotechnology
- Pharmacology
- Drug Delivery Systems
Background:
- Antibody therapeutics have revolutionized medicine but face limitations.
- The 'Paradox of Specificity' arises from systemic administration negating targeted action.
- Current antibody-centric models hinder further therapeutic advancements.
Purpose of the Study:
- To propose a paradigm shift towards Antibody-Carrier Integrated Systems (ACIS).
- To address the 'Paradox of Specificity' in antibody-based therapies.
- To outline strategies for developing intelligent drug delivery systems.
Main Methods:
- Systematic review of strategies for ACIS development.
- Analysis of antibody stability and spatiotemporal release kinetics.
- Evaluation of localized delivery and computational co-design.
Main Results:
- ACIS redefines the delivery system as an active 'contextual intelligence layer'.
- Strategies include enhancing antibody stability and programming release kinetics.
- Localized delivery and computational co-design are key to ACIS realization.
Conclusions:
- Resolving the 'Paradox of Specificity' is crucial for antibody therapeutics.
- ACIS offers a roadmap to unlock the full potential of antibody-based precision medicine.
- A future of intelligent, context-aware drug delivery systems is envisioned.
