Comprehensive mutagenesis maps the effect of all single-codon mutations in the AAV2 rep gene on AAV production

eLife
Recombinant adeno-associated viruses (rAAVs) are the predominant gene therapy vector. Several rAAV vectored therapies have achieved regulatory approval, but production of sufficient rAAV quantities remains difficult.

Directed evolution of novel AAV variants using the MCMS library for enhanced CNS tropism and reduced liver targeting in mice

Molecular Therapy: Methods & Clinical Development
Systemic delivery of adeno-associated virus serotype 9 (AAV9) to the central nervous system (CNS) is insufficient due to hindrance from the tight junctions of the blood-brain barrier (BBB).

Purification of Disassembled Capsid Protein by Hydroxyapatite Chromatography Enhances Virus‐Like Particle Recovery

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Virus‐like particles (VLPs) are a promising modality with extensive applications in prophylactic and therapeutic vaccine design. Human Papillomavirus (HPV) vaccines are one such example where VLP vaccine applications have led to the successful reduction in HPV‐associated diseases, such as cervical cancer.

Engineering a bivalent nanoparticle vaccine with PCV2 capsid protein and PRRSV epitopes

Journal of Nanobiotechnology
Coinfection with multiple viruses is a common occurrence in the pig industry. Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) are two significant pathogens, with a notable prevalence of their coinfection observed in clinical settings.

Enhancing Adeno‐Associated Virus 2 Capsid Engineering Through Co‐Evolutionary Coupling

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Adeno‐associated virus (AAV) has emerged as a leading platform for gene therapy. However, to unlock the full potential, their manufacturing yields, stability, and efficacy must all be improved. Rational design is limited by poor predictability and the potential impact of mutations on multiple important vector properties.

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Demonstration of nanofiltration‐based virus safety for AAV manufacturing using model viruses

Biotechnology Progress, EarlyView.
Abstract Virus safety for biopharmaceutical products has been a well‐established concern for several decades. While various virus reduction steps have been identified and implemented for traditional plasma‐derived and monoclonal antibody products, there are various challenges to achieving the same virus safety in emerging gene therapy products.
