Malaria is one of the world’s public health problems in terms of medical emergency with a high risk of mortality. The protozoan malaria parasites are transmitted by infected female mosquitoes . The most pathogenic human malaria parasite, Plasmodium falciparum, has gradually expanded in last three decades . Choloroquine is the cheapest and the most widely used drug in almost endemic countries. However, Plasmodium falciparum exhibits resistance to their drug. Resistance to the combination of sulfadoxine-pyrimethamine was also already emerged . Farnesyltransferase have been identified in eukaryotic organisms, including pathgenic protozoa of the genera Plasmodium [3, 4]. Therefore, the inhibition of farnesyltransferase has been suggested as a new strategy for the malaria treatment. However, the exact mechanism of action of this class of agents is still unknown . In addition, the effect of farnesyltransferase inhibitor on malaria mitochondria level is not fully understood. In this study, the effect of farnesyltransferase inhibitor on the function of mitochondria of Plasmodium falciparum were investigated experimentally. The oxygen distribution and the morphological shape of farnesyltransferase inhibitor-treated mitochondria were examined under in vitro condition. From this study, we found farnesyltransferase inhibitor is very important to understand the mitochondrial function of Plasmodium falciparum as an antimalarial drug.
Culture of malaria parasites.
Synchronization of Plasmodium falciparum.
Determination of oxygen gradients in malaria.
In this study, farnesyltransferase inhibitor was treated to RBCs (Red blood cells) uninfected by Plasmodium falciparum. Farnesyltransferase inhibitor has noticeable effects on mitochondrial function of malaria parasites, compared to the control case for non-infected RBCs.
Oxygen distribution and morphological shape of farnesyltransferase inhibitor-treated mitochondria were investigated under in vitro condition. The farnesyltransferase inhibitor was observed to be very important to understand the mitochondrial function of malaria parasite as an effective antimalarial drug.
