The Ad5-Lf pseudoadenovirus nanostructure (RPAN) was produced using homologous recombination in E. coli cells. This construction provided efficient expression of the Lf gene in permissive cell culture with high production rate of recombinant protein similar to native human Lf in some physical, chemical, and biological properties. Single intravenous injection of the construction into mice and rats was effective for prolonged production and circulation of recombinant human Lf in blood of experimental animals without toxic effects. The produced construction is promising for providing prolonged production of recombinant human Lf in the human body.

Comparative antimicrobial activity of lactoferrins from various sources (native lactoferrin from Laprot, human hololactoferrin, recombinant human lactoferrin isolated from the cultural medium of permissive cell culture transfected using pseudoadenovirus nanostructure with the human lactoferrin gene, and native bovine lactoferrin) was studied to prove the possibility of their use for development of antimicrobial drugs. It was shown that all the substances were active against the Bacillus standard strains. The antibacterial activity was almost independent of the degree of saturation the lactoferrin molecules with Fe3+.

The goal of this work was to develop a system for efficient production of human lactoferrin (Lf) in human body. It was shown using the model of cisplatin (DDP)-induced toxicosis that human Ad5-based RPAN with human Lf gene expressing cassette in its genome provides high rate of expression of Lf gene in animal body.
