Abstract

This video demonstrates the generation of an in vitro malaria-HIV co-infection cell culture model. HIV-infected peripheral blood mononuclear cells co-cultured with Plasmodium falciparum parasitized erythrocytes potentially support each other's growth and provide insights into the immune responses and disease progression in HIV and malaria co-infections.

Protocol

All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. CAUTION: Working with human blood samples and human malaria parasites requires precautionary measures. Always wear a lab coat, and gloves, and work in a level 2 Biosafety cabinet. In the event of accidental percutaneous exposure to human malaria, report to Health and Safety for prophylactic treatment. Additional safety considerations should also be put in place…
