(Submitter supplied) Differentiation from asexual blood stages to sexual gametocytes is required for transmission of malaria parasites from the human to the mosquito host. Preventing gametocyte commitment and development would block parasite transmission, but the underlying molecular mechanisms behind these processes remain poorly understood. Here, we report that the ApiAP2 transcription factor, PfAP2-G2 (PF3D7_1408200) plays a critical role in the maturation of Plasmodium falciparum gametocytes. more...

(Submitter supplied) Differentiation from asexual blood stages to sexual gametocytes is required for transmission of malaria parasites from the human host to mosquitos, where sexual fertilization occurs to complete the lifecycle. Although preventing gametocyte development would block parasite transmission, the molecular mechanisms underlying sexual commitment and gametocyte maturation are still relatively unknown. Previous studies identified an ApiAP2 protein, AP2-G2, which plays a critical role in gametocyte maturation in rodent malaria parasite Plasmodium berghei by acting as the repressor of asexual stage genes in gametocytes. more...

(Submitter supplied) Gametocytogenesis, the process by which malaria parasites produce sexual forms that can infect mosquitoes, is essential for the transmission of malaria. A transcriptional switch of the pfap2-g gene triggers sexual commitment, but how the complex multi-step process is precisely programed remains largely unknown. Here, by systematic functional screening of a panel of ApiAP2 transcription factors, we identify six new apiAP2 members associated with gametocytogenesis in Plasmodium falciparum. more...

(Submitter supplied) In the malaria parasite Plasmodium falciparum, the switch from asexual multiplication to sexual differentiation into gametocytes is essential for transmission to mosquitos. One of the key determinants of sexual commitment is the transcription factor PfAP2-G, which has been proposed to orchestrate this crucial cell fate decision by driving expression of gametocyte genes. Here we identify for the first time the direct targets of PfAP2-G and demonstrate that it dynamically binds hundreds of sites across the genome. more...

(Submitter supplied) To determine the genome-wide occupancy of the Plasmodium falciparum transcriptional regulator of invasion PfAP2-I (PfDd2_100013100/PF3D7_1007700), we used chromatin immunoprecipitation coupled with next-generation sequencing (ChIP-seq). Synchronized, schizont stage, 40 hours post-invasion, cultures of parasites expressing the AP2-I-GFP fusion protein were treated with formaldehyde to crosslink proteins to DNA and harvested. more...

(Submitter supplied) Periodic fever is the most characteristic clinical feature of human malaria. However, how parasites survive malarial febrile episodes, which often involve temperatures of >40ºC, is not known. To understand the molecular basis of heat shock (HS) resistance in Plasmodium falciparum, we took advantage of previously developed P. falciparum lines adapted to periodic HS (3D7-A-HS) and their non-selected controls maintained in parallel (3D7-A). more...

(Submitter supplied) Periodic fever is the most characteristic clinical feature of human malaria. However, how parasites survive malarial febrile episodes, which often involve temperatures of >40ºC, is not known. Plasmodium falciparum cultures adapted to periodic heat shock were used to identify PfAP2-HS as a transcription factor that is essential for survival at febrile temperatures. Transcriptomic analysis was performed to compare the effect of heat shock in parasites presenting the wild type form of PfAP2-HS (10E) and parasites that have defects in this protein, either a premature stop codon mutation (10G) or the deletion of the entire pfap2-hs gene (10E_pfap2-hs). more...
