Beyond Hemoglobin: Screening for Malaria Host Factors

Abstract

Severe malaria is caused by the Apicomplexan parasite Plasmodium falciparum, and results in significant global morbidity and mortality, particularly among young children and pregnant women. P. falciparum exclusively infects human erythrocytes during clinical illness, and several natural erythrocyte polymorphisms are protective against severe malaria. Since erythrocytes are enucleated and lack DNA, genetic approaches to understand erythrocyte determinants of malaria infection have historically been limited. This review highlights recent advances in the use of hematopoietic stem cells to facilitate genetic screening for malaria host factors. While challenges still exist, this approach holds promise for gaining new insights into host-pathogen interactions in malaria.
