Evaluating experimental cerebral malaria using oxidative stress indicator OKD48 mice.

Cerebral malaria is a fatal complication of malaria. Conventional methods for evaluating experimental cerebral malaria have several drawbacks. Therefore, we aimed to develop an easy-to-use method for evaluating experimental cerebral malaria using OKD48 (Keap1-dependent Oxidative stress Detector, No-48-luciferase) mice to evaluate oxidative stress. OKD48 mice infected with Plasmodium berghei ANKA strain (PbA) suffered from experimental cerebral malaria and oxidative stress was successfully detected in the brains of living OKD48 mice developing experimental cerebral malaria. Oxidative stress in the brain was dependent on the development of experimental cerebral malaria, as prevention of experimental cerebral malaria did not elicit oxidative stress. We provide a novel evaluation method for experimental cerebral malaria using oxidative stress indicator OKD48 mice.
