Cerebral malaria (CM) is a life-threatening complication of the malaria disease caused by Plasmodium falciparum infection and is responsible for the death of half a million people annually. The molecular pathogenesis underlying CM in humans is not completely understood, although sequestration of infected erythrocytes in cerebral microvessels is thought to play a major role. In contrast, experimental cerebral malaria (ECM) models in mice have been thought to be distinct from human CM, and are mainly caused by inflammatory mediators. Here, to understand the spatial distribution and the potential sequestration of parasites in the whole-brain microvessels during a mouse model of ECM, we utilized the new tissue-clearing method CUBIC (Clear, Unobstructed, Brain/Body Imaging Cocktails and Computational analysis) with light sheet fluorescent microscopy (LSFM), and reconstructed images in three-dimensions (3D). We demonstrated significantly greater accumulation of Plasmodium berghei ANKA (PbANKA) parasites in the olfactory bulb of mice, compared with the other parts of the brain, including the cerebral cortex, cerebellum, and brainstem. Furthermore, we show that PbANKA parasites preferentially accumulate in the brainstem when the olfactory bulb is surgically removed. This study therefore not only highlights a successful application of CUBIC tissue-clearing technology to visualize the whole brain and its microvessels during ECM, but it also shows CUBIC's future potential for visualizing pathological events in the whole ECM brain at the cellular level, an achievement that would greatly advance our understanding of human cerebral malaria.
