AI Identifies Prion Proteins as Unexpected Source of Antibiotic Candidates
New antibiotic candidates for drug-resistant bacteria may reside inside prions, misfolded proteins in the brain best known for rare and fatal degenerative brain diseases. Prion and prion-like proteins may hide short peptides, called "prionins," that can kill bacteria, suggesting proteins best known for their role in neurodegeneration may contain molecular features linked to immune defense, according to new research from the Perelman School of Medicine at the University of Pen
Artificial intelligence has revealed that prion proteins, typically associated with neurodegenerative diseases, may harbor new antibiotic candidates. Researchers from the Perelman School of Medicine at the University of Pennsylvania discovered that prions and prion-like proteins can contain short peptides, termed 'prionins,' capable of killing bacteria. This finding suggests a potential dual role for these proteins, linking neurodegeneration with immune defense mechanisms. The discovery is particularly significant in the fight against drug-resistant bacteria. Identifying novel sources of antibiotics is a critical global health priority. The use of AI in this research accelerates the discovery process. These 'prionins' could form the basis for new therapeutic agents. This work opens up an unconventional avenue for antibiotic development.
This AI-driven discovery identifies a surprising new source for potential antibiotics within disease-associated proteins, offering a novel strategy to combat the growing threat of antimicrobial resistance.
