ocuses on optimizing proteins to mitigate immune responses, promising improved efficacy and reduced side effects in gene therapy.
Researchers have harnessed the capabilities of artificial intelligence (AI) to revolutionize gene therapy by redesigning a crucial protein involved in the delivery process. This breakthrough, detailed in the journal Nature Machine Intelligence, focuses on optimizing proteins to mitigate immune responses, promising improved efficacy and reduced side effects in this therapy.
Assistant Professor Michael Garton from the University of Toronto acknowledges the immense promise of gene therapy but highlights the significant hurdle posed by the body’s pre-existing immune response to viral vectors. This challenge led the research team to zero in on hexons, fundamental proteins in adenovirus vectors, which hold tremendous potential for this therapy if not for the immune problem.
Immune responses triggered by specific antibodies obstruct the precise targeting of gene therapy vehicles, resulting in reduced efficacy and severe adverse effects. To overcome this, Garton’s lab employed AI to custom-design hexon variants that deviate from natural sequences, aiming to create structures unrecognizable by the immune system.
Traditional methods of protein design involve extensive trial and error, incurring high costs. The researchers introduced the AI framework, ProteinVAE, specifically tailored for designing long proteins like hexons. Unlike larger models, ProteinVAE efficiently learns from limited data, supporting fast training and inference on standard GPUs without demanding high computational resources.
The AI model, validated through molecular simulation, demonstrates a remarkable ability to alter a significant percentage of the protein’s surface. This transformative feature potentially allows the redesigned proteins to evade immune responses, enhancing their effectiveness in gene therapy.
Lead author Suyue Lyu, a Ph.D. candidate, envisions broader applications for the AI model beyond gene therapy protein design. The researchers believe that ProteinVAE could be extended to support protein design in various disease cases, indicating the potential to design new biological entities with therapeutic value for novel medical treatments.
