Malaria is one of the epidemics that can cause human death. Accurate and rapid diagnosis of malaria is important for treatment. Due to the limited number of data and human factors, the prediction performance and reliability of traditional classification methods are often affected. In this study, we propose an efficient and novel classification network named Attentive Dense Circular Net (ADCN) which based on Convolutional Neural Networks (CNN).

The malaria parasite Plasmodium falciparum is a protozoan that develops in red blood cells (RBCs) and requires various host factors. For its development in RBCs, nutrients not only from the RBC cytosol but also from the extracellular milieu must be acquired. Although the utilization of host nutrients by P. falciparum has been extensively analysed, only a few studies have reported its utilization of host serum proteins. Hence, the aim of the current study was to comprehensively identify host serum proteins taken up by P. falciparum parasites and to elucidate their role in pathogenesis.

NOT Open Access | Identification of essential exported Plasmodium falciparum protein kinases in malaria-infected red blood cells

FIKK kinases in the human malaria parasite Plasmodium falciparum are attractive targets for new anti‐malaria drugs, as they have no orthologues in humans and have been linked to disease severity. Six FIKKs are known to be exported into red blood cells (RBCs) where they mediate dramatic structural and functional changes to RBCs that are central to pathogenesis. Eleven members of this family, which are predicted to be exported into infected RBCs (iRBCs), remain uncharacterised.

The most widely used antimalarial drugs belong to the quinoline family. Their mode of action has not been characterized at the molecular level in vivo. We report the in vivo mode of action of a bromo analog of the drug chloroquine in rapidly frozen Plasmodium falciparum-infected red blood cells.

In this work, we developed two types of cell model, one with an included parasite, and the other without an included parasite. The former is a representation of real malaria-infected RBCs, in which the parasite is treated as a rigid body.
