Purpose:

Malaria Invasion is the second in a series of educational mobile games 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. The first mobile game was CD4 Hunter™. These games are primarily intended for use as a learning tool to supplement biomedical science curriculum in higher education, by intersecting science with engaging game mechanics.

Game Features:

Malaria Invasion is a 3-level game in which players take the role of the malaria parasite, Plasmodium in the blood-stage of infection. Specifically, players play as a Plasmodium merozoite that arose in the bloodstream of an individual that had been bitten by an infected mosquito.

By intersecting real science, with attractive visuals and animations, and simple gameplay, each game level teaches players about essential aspects of the complex mechanism by which merozoites invade RBCs while evading the immune system:

• Level 1, Circulation: The goal is to identify and infect as many RBCs as possible and not be detected by the immune system.

• Level 2, Attachment: The goal is to attach specific proteins produced by the merozoite to their specific receptors on the RBC. The successful protein-receptor binding will increase the intracellular calcium needed to proceed with the invasion process.

• Level 3, Invasion: The goal is to develop the tight junctions necessary to engage the actin-myosin motor and drive the merozoite into the RBC.

Learning Goals:

1. Explain the role of the Plasmodium merozoite in the progression of the blood-stage malaria infection.

2. Identify RBCs and their specific cell-surface receptors as the merozoite targets in the post-hepatic stage of the Plasmodium replication cycle.

3. Identify the key Plasmodium organelles involved in RBC invasion and define the function of essential protein ligands they secrete to facilitate invasion.

4. Explain the role of the essential ligand-receptor pairs in the process of RBC invasion by the Plasmodium

5. Correlate the evasion of the immune system with the progression of the malaria infection during the blood stage of the Plasmodium replication cycle.

6. Identify important metabolic and structural changes involved in the process of Plasmodium merozoite invasion of RBCs.

Malaria Invasion was designed and developed by faculty of the Department of Microbiology and Immunology (Mary Ann Comunale, EdD, MS and Sandra Urdaneta-Hartmann, MD, Ph.D., MBA) at Drexel University College of Medicine, and an undergraduate student from Drexel University’s Game Design Program (John Harvey).

Lawrence Bergman, Ph.D., James Burns, Ph.D., and Akhil Vaidya, Ph.D., also faculty in the Department of Microbiology and Immunology, contributed their expertise on malaria.

Brian Wigdahl, Ph.D., Chair of the Department of Microbiology and Immunology and Executive Director of the Institute for Molecular Medicine and Infectious Disease is the Executive Producer of Malaria Invasion.

Funding for this project was provided by the Department of Microbiology and Immunology and the Institute for Molecular Medicine and Infectious Disease. Additional funding was granted by Drexel University’s Office of the Provost and the Steinbright Career Development Center.
