WEHI-842		Pf3D7 Plasmodium falciparum 3D7 P. falciparum strain 3D7 (Pf3D7) was derived from isolate NF54 by limiting dilution. The complete genome of Pf3D7 has been sequenced (GenBank: LN999946.1). Pf3D7 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center (MR4) and is sensitive to a panel of antimalarial compounds including chloroquine and pyrimethamine. ✖	Parasite growth inhibition assay	-	-	6.4	pEC₅₀	4

WEHI-842		PfNF54 Plasmodium falciparum NF54 P. falciparum strain NF54 (PfNF54) was derived from a patient who had never left the Netherlands. PfNF54 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center (MR4) and is sensitive to a panel of antimalarial compounds including chloroquine and pyrimethamine. ✖	Standard membrane feeding assay (SMFA)	-	-	-	-	5
⤷	Oocyst count: WEHI-842 demonstrates a dose-dependent inhibitory effect on transmission fitness [5] Lifecycle stages: Plasmodium mosquito host stage (gametocyte, gamete, zygote, ookinete, oocyst, sporozoite)

Malaria Pharmacology Comments
The P. falciparum genome encodes 10 aspartic proteases, classed together as the plasmepsin family, which are involved in diverse cellular processes [3]. P. falciparum plasmepsin V (PfPMV) is an endoplasmic reticulum (ER) localized enzyme involved in processing proteins for export into the host erythrocyte, which is key to parasite survival and immune evasion [7]. Most exported proteins contain a signal sequence for entry into the ER as well as the Plasmodium Export Element (PEXEL) motif [6,8]. PfPMV cleaves the PEXEL motif, revealing the export signal for subsequent trafficking to the host erythrocyte [1]. This enzyme is a promising target for the development of chemotherapeutic and transmission-blocking antimalarial therapies, with studies demonstrating an essential role during both the asexual blood stage [1-2,9] and gametocytogenesis [5].
