CD4 Hunter is a fast-paced, educational mini-game in which players take on the role of a human immunodeficiency virus type 1 (HIV-1) virion. By immersing real science within simple game play, users learn about the first step of HIV-1’s fascinating and complex replication cycle: binding and attachment. CD4 Hunter invites players to enter the bloodstream and grow their viral population by infecting specific target cells, while evading the immune system.
Download CD4 Hunter for free to:
• Learn complex science through fast-paced and addictive game play;
• Hunt for target cells in the human bloodstream;
• Control and grow your viral population; and
• Face antibody attacks as the immune system fights infection.
CD4 Hunter is the first in a series of mini-games to be developed by the Institute for Molecular Medicine and Infectious Disease at Drexel University College of Medicine, to introduce players to the dynamic world of infectious disease. CD4 Hunter was designed to supplement learning about the multi-stage process of the HIV-1 replication cycle, through interactive gameplay. This app is intended for use in biomedical science curriculum in higher education. Users apply knowledge about the biological processes involved during HIV-1 replication to advance in the game. CD4 Hunter focuses on meeting the following learning objectives:
1. Identify gp120 as a basic element of HIV-1 structure and apply knowledge about its function in the process of viral binding and entry.
2. Identify CD4+ T cells as targets for HIV-1 infection in humans and apply knowledge about their role in viral pathogenesis.
3. Identify and match the molecules on the surface of HIV-1 (i.e., gp120) and T cells (i.e., CD4+ receptor, and CCR5 and CXCR4 co-receptors) involved in viral binding and entry.
4. Apply concepts of viral tropism and immune evasion mechanisms to complete the HIV-1 infection cycle in CD4+ T cells.

Ratings and Reviews
Fun & informative—could be more detailed!
In the game, the extent of the replication process that is shown is pretty minimal— the HIV virus binds, enters the nucleus, and then morphs into more virions. This isn’t inaccurate, but is very simplified. It would be interesting to get a sense of how this replication occurs; namely, reverse transcriptase converts HIV RNA to DNA, and then enters the cell nucleus and combines with the cell’s DNA, etc. the game could show this process, or make the player convert RNA to DNA in some kind of matching game, as a “second level.”
To make the game more realistic, yet still playable, I would want the game designers to not only include T-cells, but also include other host cells that HIV can infect. Macrophages and dendritic cells, along with T-cells, can be infected by HIV.
Fun and informative
CD4 Hunter is a fun and informative app. I got to learn a little more about the cell biology of HIV infection. I can’t wait to see more apps like this!
