This protocol details preparing recombinant adenoviruses for efficient gene delivery to target cells. Adenoviral vectors offer high transduction efficiency without insertional mutagenesis risk, ideal for expressing G-protein-coupled receptors.

Area of Science:

  • Molecular Biology
  • Virology
  • Gene Therapy

Background:

  • Adenoviruses are nonenveloped viruses with double-stranded DNA genomes.
  • Their episomal replication avoids insertional mutagenesis, a key safety feature.
  • Adenoviral vectors can accommodate large foreign DNA inserts (up to 30 kb).

Purpose of the Study:

  • To describe the protocol for preparing recombinant adenoviruses.
  • To outline the method for infecting target cells for protein expression.
  • To highlight the utility of adenoviral vectors for expressing G-protein-coupled receptors and other proteins.

Main Methods:

  • Preparation of recombinant adenoviruses.
  • Infection of target cells using adenoviral vectors.
  • Expression of G-protein-coupled receptors or other proteins of interest.

Main Results:

  • Adenoviral vectors demonstrate highly efficient gene transduction (up to 100%).
  • Viral infection is straightforward and preserves cell membrane integrity.
  • Cells resistant to plasmid transfection, including non-dividing cells, can be infected.

Conclusions:

  • Recombinant adenoviruses are effective tools for transient protein expression.
  • Adenoviral vectors provide a safe and efficient gene delivery method.
  • This protocol facilitates the study of G-protein-coupled receptors and other proteins in various cell types.
