An international team led by a Korean scientist has used artificial intelligence to design protein structures that replicate the self-assembly principles of natural viruses. The achievement marks a step forward in creating synthetic shells capable of carrying therapeutic cargo.
The work draws on decades of research into viral capsids — the protein shells that protect viral genetic material. By mimicking these structures, scientists aim to develop safer, more effective delivery vehicles without using actual viruses.
According to the study published in a peer-reviewed journal, the AI-designed proteins form large, hollow shells that assemble spontaneously. The team demonstrated the structures using electron microscopy, confirming their virus-like geometry.
The breakthrough could reshape how vaccines and medicines are packaged and delivered. Synthetic shells might reduce immune reactions compared to viral vectors and allow for more precise targeting of specific cells.
Experts caution that the approach remains in early stages. Challenges include scaling production and ensuring the shells break down safely in the body. Further animal testing is needed before human trials can begin.
