Pseudovirus Emerges as a Novel Reference Material for Gene Therapy

Research from the National Institutes for Food and Drug Control in Beijing, China, has highlighted the crucial role of pseudovirus in ensuring the reliability of nucleic acid testing (NAT) systems. As the world faces unprecedented challenges from novel infectious pathogens, NAT has become an indispensable diagnostic tool for public health surveillance, clinical decision-making, and food safety control. However, current reference materials (RMs) in the NAT area have significant limitations, and pseudovirus has emerged as a novel RM that integrates non-replicative viral vectors with target nucleic acid sequences.

Key Takeaways:

• The pseudovirus has demonstrated superior performance in mimicking authentic viral structure, biosafety, and stability compared to conventional RMs.
• The engineering strategies of pseudovirus platforms have been critically summarized, highlighting their emerging role in ensuring the reliability of NAT systems.
• Standardized pseudovirus RMs are being developed to address key challenges in scalability, stability, and clinical validation, aiming to provide guidance for optimizing pseudovirus design and practical implementation.
• The pseudovirus has the potential to facilitate the continuous improvement and innovation of NAT technologies, making them more accurate and reliable.
• The National Institutes for Food and Drug Control have been at the forefront of developing pseudovirus as a novel RM, with research and development efforts led by Leiqi Zheng and Sihong Xu.
• The research has sparked interest in exploring the potential of pseudovirus in other areas, such as gene therapy and bioengineering.
