Transcriptional signature of CD4hiCD38hi T cells from patients with Plasmodium falciparum or Plasmodium knowlesi malaria

Project description:We observed by flow cytometry a population of CD4 T cells expressing very high levels of the coreceptor CD4 and the ectoenzyme CD38 (termed CD4hiCD38hi) in the peripheral blood of patients from Sabah and Papua with Plasmodium falciparum or Plasmodium knowlesi malaria. CD4hiCD38 T cells express genes associated with type 1 regulatory T cells.

Global gene expression of the rodent malaria parasites Plasmodium yoelii, Plasmodium berghei and Plasmodium chabaudi blood-stage parasites

Project description:The purpose of this research is to identify and evaluate the global gene expression of the rodent malaria parasites Plasmodium yoelii, Plasmodium berghei and Plasmodium chabaudi blood-stage parasites and specifically compare the blood stage gene expression profiles of samples derived from previous studies on Plasmodium falciparum, Plasmodium vivax and Plasmodium knowlesi

Discovery of telomere repeat-binding factor in the malaria parasite Plasmodium falciparum

Project description:ChIP-seq experiments were performed for the putative telomere repeat-binding factor (PfTRF) in the malaria parasite Plasmodium falciparum strain 3D7. The gene encoding this factor (PF3D7_1209300) was endogenously tagged with either a GFP- or a 3xHA-tag and these transgenic parasite lines were used in ChIP-sequencing experiments. Sequencing of the ChIP and input libraries showed enrichment of PfTRF at all telomere-repeat containing chromosome ends (reference genome Plasmodium falciparum 3D7 from PlasmoDB version 6.1) as well as in all upsB var promoters.In addition,PfTRF was enriched at seven additional, intra-chromosomal sites and called in the PfTRF-HA ChIP-seq only. Plasmodium falciparum 3D7 parasites were generated with -GFP or -3xHA C-terminal tagged TRF (PF3D7_1209300). Nuclei were isolated from formaldehyde cross-linked schizont-stage transgenic parasites and used to prepare chromatin. Chromatin immunoprecipitations were performed using mouse anti-GFP (Roche Diagnostics, #11814460001) or rat anti-HA 3F10 (Roche Diagnostics, #12158167001). Sequencing libraries were prepared according to a Plasmodium-optimized library preparation procedure including KAPA polymerase-mediated PCR amplification.

Replication origin mapping in the malaria parasite Plasmodium falciparum

Project description:The malaria parasite Plasmodium falciparum replicates via schizogony: a fundamentally unusual type of cell cycle involving asynchronous replication of multiple nuclei within the same cytoplasm. It also has one of the most A/T-biased genomes ever sequenced. Here, we present the first comprehensive study of the specification and activation of DNA replication origins during Plasmodium schizogony. Potential replication origins were found to be abundant, with ORC1-binding sites detected every ~800 bp throughout the genome. They had no motif enrichment, but were biased towards areas of higher G/C content. Origin activation was then measured at single-molecule resolution via DNAscent technology, and was much less dense than ORC1-binding sites, with origins activated preferentially in areas of low transcriptional activity. Consistently, replication forks moved slowest through the most highly transcribed genes, suggesting that conflicts between transcription and origin firing inhibit efficient replication, and that P. falciparum has evolved its S-phase to minimise such conflicts.

Transcriptome profiling reveals functional variation in Plasmodium falciparum parasites from controlled human malaria infection studies

Project description:The objective of this study is to characterize the overall transcriptome of P. falciparum NF54 derived from a controlled-human malaria infection (CHMI) study. Healthy, immunologically naïve human volunteers were infected intradermally or intravenously with different dosages of Plasmodium falciparum sporozoites (Sanaria® PfSPZ Challenge). Parasites were isolated from these volunteers and subjected to a range of in vitro culture generation prior to RNA collection.

Bulk RNA-seq of the human malaria parasite Plasmodium falciparum 3D7 cultured under different iron conditions

Project description:Background: Host iron deficiency is protective against severe malaria as the human malaria parasite Plasmodium falciparum depends on free iron from its host to proliferate. Due to the absence of transferrin, ferritin, ferroportin, and a functional heme oxygenase, the parasite’s essential pathways of iron acquisition, storage, export, and detoxification differ from those in humans and may thus be excellent targets for therapeutic development. However, the proteins involved in these processes in P. falciparum remain largely unknown. Experimental design: To identify iron-regulated mechanisms and putative iron transporters in the human malaria parasite Plasmodium falciparum 3D7, we carried out whole-transcriptome profiling using bulk RNA-sequencing. The parasites were cultured either using erythrocytes from a donors with high, medium (healthy) or low iron status (experiment 1); or with red blood cells from another healthy donor in the presence or absence of 0.7 µM hepcidin, a specific ferroportin inhibitor and iron-regulatory hormone (experiment 2). This concentration of hepcidin was reported to reduce binding of ferrous iron to ferroportin by 50% in vitro (39). Samples from three biological replicates each were harvested at the ring and trophozoite stage (6 – 9 and 26 – 29 hours post invasion, hpi) during the second intra-erythrocytic developmental cycle under the conditions specified.
