Bio blog: New therapy targeting the malaria parasite’s Achilles’ heel

Malaria is a devastating disease, affecting 200 million people worldwide and causing more than 600 000 deaths each year. In the past decade, great inroads have been made in reducing the number of infections, primarily through the implementation of insecticide-laced bed nets, and also reducing the death rate with combination therapies. However the emergence of drug-resistant malaria is rendering these therapies less effective, and there is an urgent need to develop novel therapies to cure malaria.

Is the antimalarial agent Chloroquine effective for the treatment of COVID-19? 抗疟药氯喹对COVID-19的治疗有效吗?

The Take-Home Points:

Antimalarials like chloroquine and hydroxychloroquine are currently being studied for their effectiveness and safety when used to treat COVID-19. While Chloroquine may be purchased from a licenced pharmacist in Singapore for the prevention of malaria, we do not recommend self-medication for treatment of COVID-19 without proper medical assessment and evaluation. If you suspect that you could have COVID-19 infection or experiencing COVID-19 symptoms, seek medical attention immediately.

关键点:

抗疟疾药(如氯喹和羟基氯喹chloroquine and hydroxychloroquine)目前正用於治疗COVID-19时有效性和安全性的研究。虽然可以从本国药剤师那里购买氯喹来预防疟疾,但我们並不建议您在没有适当医生检验的情况下自行用药治疗COVID-19。如果您怀疑自己可能感染了COVID-19或出现了相关症状,请立即就医。

Molecular architecture and domain arrangement of the placental malaria protein VAR2CSA suggests a model for carbohydrate binding [Glycobiology and Extracellular Matrices]

VAR2CSA is the placental-malaria–specific member of the antigenically variant Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) family. It is expressed on the surface of Plasmodium falciparum-infected host red blood cells and binds to specific chondroitin-4-sulfate chains of the placental proteoglycan receptor. The functional ∼310 kDa ectodomain of VAR2CSA is a multidomain protein that requires a minimum 12-mer chondroitin-4-sulfate molecule for specific, high affinity receptor binding. However, it is not known how the individual domains are organized and interact to create the receptor-binding surface, limiting efforts to exploit its potential as an effective vaccine or drug target. Using small angle X-ray scattering and single particle reconstruction from negative-stained electron micrographs of the ectodomain and multidomain constructs, we have determined the structural architecture of VAR2CSA. The relative locations of the domains creates two distinct pores that can each accommodate the 12-mer of chondroitin-4-sulfate, suggesting a model for receptor binding. This model has important implications for understanding cytoadherence of infected red blood cells and potentially provides a starting point for developing novel strategies to prevent and/or treat placental malaria.

Role of phospholipid synthesis in the development and differentiation of malaria parasites in the blood [Microbiology]

The life cycle of malaria parasites in both their mammalian host and mosquito vector consists of multiple developmental stages that ensure proper replication and progeny survival. The transition between these stages is fueled by nutrients scavenged from the host and fed into specialized metabolic pathways of the parasite. One such pathway is used by Plasmodium falciparum, which causes the most severe form of human malaria, to synthesize its major phospholipids, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine. Much is known about the enzymes involved in the synthesis of these phospholipids, and recent advances in genetic engineering, single-cell RNA-Seq analyses, and drug screening have provided new perspectives on the importance of some of these enzymes in parasite development and sexual differentiation and have identified targets for the development of new antimalarial drugs. This Minireview focuses on two phospholipid biosynthesis enzymes of P. falciparum that catalyze phosphoethanolamine transmethylation (PfPMT) and phosphatidylserine decarboxylation (PfPSD) during the blood stages of the parasite. We also discuss our current understanding of the biochemical, structural, and biological functions of these enzymes and highlight efforts to use them as antimalarial drug targets.

Protein modification characteristics of the malaria parasite Plasmodium falciparum and the infected erythrocytes [Research]

Malaria elimination is still pending on the development of novel tools that rely on a deep understanding of parasite biology. Proteins of all living cells undergo a myriad number of posttranslational modifications (PTMs) that are critical to multifarious life processes. An extensive proteome-wide dissection revealed a fine PTM map of most proteins in both Plasmodium falciparum, the causative agent of severe malaria, and the infected red blood cells. More than two-thirds of proteins of the parasite and its host cell underwent extensive and dynamic modification throughout the erythrocytic developmental stage. PTMs critically modulate the virulence factors involved in the host-parasite interaction and pathogenesis. Furthermore, P. falciparum stabilized the supporting proteins of erythrocyte origin by selective de-modification. Collectively, our multiple omic analyses, apart from having furthered a deep understanding of the systems biology of P. falciparum and malaria pathogenesis, provide a valuable resource for mining new antimalarial targets.
