Summary

This study introduces a novel method for efficient foreign gene expression in B-cell lines (B-LCL) using modified adenovirus. This technique enables transient gene expression for up to 17 days, aiding research in Epstein-Barr virus (EBV) and B-cell immunology.

Area of Science:

  • Virology
  • Molecular Biology
  • Immunology

Background:

  • Epstein-Barr virus (EBV) is a herpesvirus linked to various lymphomas and crucial for human immunology studies.
  • B-cell lines (B-LCL) are valuable models for EBV research and immunological investigations.

Purpose of the Study:

  • To develop an efficient system for foreign gene expression in B-LCL.
  • To utilize biotinylated adenovirus as an endosome-disrupting agent for enhanced gene delivery.

Main Methods:

  • Plasmid DNA coupled to viral particles via streptavidin-polylysine chimeric proteins.
  • Biotinylated adenovirus used to facilitate endosomal escape and gene expression in B-LCL.
  • Transient expression systems employed for in vitro gene delivery and analysis.

Main Results:

  • Achieved foreign gene expression in up to 67% of B-LCL.
  • Sustained gene expression for at least 17 days.
  • Successfully expressed various reporter genes, HIV genes, and an EBV-specific gene in B-LCL.

Conclusions:

  • The novel system provides efficient and sustained foreign gene expression in B-LCL.
  • Potential applications include studying EBV infection, gene therapy for B-cell tumors, and producing antigen-presenting cells.
  • Enables transient expression assays without the need for clonal selection.
