Model Structure

Current therapies for acquired immunodeficiency syndrome (AIDS) include inhibitors of the enzymes required for the replication of the human immunodeficiency virus (HIV-1). An alternative therapeutic approach uses genetically modified viruses which are then capable of regulating infections by other viruses. The genetically modified virus is able to infect and kill host cells which are already infected with HIV-1, resulting in a decrease in the viral load.

This information has been obtained from in vitro experiments. The potential effectiveness of this treatment for reducing viral load in vivo has not been tested. In the study described here, Revilla and Garcia-Ramos model the potential interactions between HIV-1, its host cell, and a recombinant virus in an in vivo context (see the figure below). Model simulations suggest that the use of recombinant viruses could be effective as a treatment for reducing an individual's HIV-1 load.

Schematic diagram of a model for a double viral infection. Pathogen viral particles V infect normal host cells X, producing single-infected cells Y. These are then infected with the recombinant virus W to become double-infected cells Z. Double-infected cells can produce recombinant viral particles but not pathogen viral particles
