Peptides are versatile molecules engineered for orthopaedic applications, showing promise in bone regeneration and combating resistant infections. While challenges remain in clinical validation and AI-driven design translation, peptide engineering advances therapeutic strategies.
Area of Science:
- Orthopaedic research
- Biomaterials science
- Drug discovery
Background:
- Peptides' flexible structures enable targeted engineering for diverse orthopaedic applications.
- Evolution from natural agents like bone morphogenetic proteins to synthetic peptides.
- Existing peptide therapies include Teriparatide for bone regeneration and PLG0206 for antimicrobial applications.
Purpose of the Study:
- To examine the design principles of orthopaedic peptide applications.
- To review preclinical and clinical advancements in peptide-based orthopaedics.
- To highlight challenges and future directions in peptide engineering for orthopaedics.
Main Methods:
- Review of literature on peptide design and applications in orthopaedics.
- Analysis of clinical trial data for peptide therapeutics.
- Discussion of artificial intelligence in peptide design.
Main Results:
- Teriparatide is clinically validated for bone regeneration.
- PLG0206 shows efficacy against resistant biofilms and is in advanced clinical trials.
- Engineered peptides show potential for cartilage drug delivery, but disease-modifying osteoarthritis drugs are not yet validated.
- AI accelerates peptide design, but clinical translation is challenging.
Conclusions:
