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.

 Parasite gametocyte assay - - 7.4 pEC50 5
⤷ pEC50 7.4 (EC50 4x10-8 M) Giemsa-stained blood film counts: no stage II-V gametocytes were observed [5]
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.

Lifecycle stages: Plasmodium asexual blood stage (erythrocytic merozoite, trophozoite, erythrocytic schizont)
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]. The P. falciparum plasmepsin V (PfPMV) enzyme processes proteins for export into the host erythrocyte and has been shown to be essential for parasite asexual blood stage development [1-2]. PfPMV has also been shown to be essential for gametocyte development, validating it as a potential target for the development of transmission-blocking drugs [5].
