Optimizing phage therapy with artificial intelligence: a perspective
Phage therapy is emerging as a promising strategy against the growing threat of antimicrobial resistance. Phages and bacteria are incredibly diverse, and their interactions are complex. Current clinical applications often involve manual screening, a labor-intensive process. This perspective reviews recent advances in Artificial Intelligence (AI) to advance phage-host interactions, aiming to design more effective phage therapeutics. Concurrent synthetic biology advances enable rapid genetic manipulation, suggesting AI-derived insights could optimize synthetic phages.

Phage-Host Specificity
Understanding phage-host specificity determinants using AI is crucial for effective therapy. Identifying infectious phage strains for a given host is essential, but manual screening is challenging. AI models leverage host genome sequences to predict infection outcomes, especially for genera like Klebsiella and Escherichia. These models often focus on attachment factors like capsular K-serotype, lipopolysaccharide (LPS) outer core variations, and O-antigen serotypes. However, deeper understanding of post-attachment interactions and defense systems is needed for pathogens like Staphylococcus aureus and Pseudomonas aeruginosa. AI advancements could lead to more effective strain-level phage matching and predict resistance mutations.
Gene Discovery & Engineering
AI is accelerating the discovery of phage genes with specific functions. With a growing number of phage sequences in databases, AI helps sift through vast data to predict putative phage genes. This includes identifying anti-phage defense system counter-defenses, enzymes like depolymerases (for biofilm/capsule degradation), and lysins (for host cell lysis). For example, AI has been used to identify novel phage inhibitors of bacterial defense systems with ~50% success and to improve annotation of depolymerase genes. While experimental validation is still needed, AI significantly triages candidates for genetic optimization.
Synthetic Phage Development
AI-guided development of synthetic phages aims to create enhanced therapeutics. Synthetic biology methods allow modification of phage genomes, and AI is beginning to enable specificity programming. Deep mutational scanning data of phage receptor binding proteins, combined with AI, can identify novel binding sequences. Generative models of proteins and entire genomes are emerging, potentially leading to biologically functional synthetic phages with desired functions. Incorporating AI-identified lysins, depolymerases, and counter-defenses into engineered phages could boost treatment efficacy, but careful consideration of bioethical and environmental implications is crucial. The goal is to accelerate phage identification and optimize synthetic phages.

Case Study: AI-Accelerated Phage Inhibitor Discovery
Recent research utilized AI with protein structure and interaction prediction (AlphaFold2-Multimer) to screen two million phage genomes containing over 30 million phage genes. This process identified phage proteins predicted to fold and interact with pre-chosen bacterial defense proteins, achieving a ~50% success rate in experimentally validating novel phage inhibitors. While rigorous experimental validation is still required, this AI-driven approach significantly triages candidates, reducing the labor-intensive burden and accelerating the discovery of effective counter-defense mechanisms against bacterial immunity. This paradigm shift enables researchers to focus resources on the most promising leads, drastically speeding up the development of new phage therapeutics.
