    Antibodies to repeat-containing antigens in Plasmodium falciparum are exposure-dependent and short-lived in children in natural malaria infections

    Madhura Raghavan, Katrina L Kalantar ... Joseph L DeRisi
    The dominant targets of host immune response to malaria are repeat elements, which are short stretches of amino acids repeated within Plasmodium falciparum proteins, and these are associated with short-lived and exposure-dependent antibody responses.

    Genetic and chemical validation of Plasmodium falciparum aminopeptidase PfA-M17 as a drug target in the hemoglobin digestion pathway

    Rebecca CS Edgar, Ghizal Siddiqui ... Tania F de Koning-Ward
    Plasmodium falciparum aminopeptidase PfA-M17 is essential to parasite survival and plays a role in hemoglobin digestion, providing a rationale for further development of inhibitors against this enzyme.

    Genomic epidemiology of artemisinin resistant malaria

    MalariaGEN Plasmodium falciparum Community Project
    Plasmodium falciparum kelch13 mutations that cause artemisinin resistant malaria in Southeast Asia show markedly different patterns of evolutionary selection in Africa.

    A randomized feasibility trial comparing four antimalarial drug regimens to induce Plasmodium falciparum gametocytemia in the controlled human malaria infection model

    Isaie J Reuling, Lisanne A van de Schans ... Teun Bousema
    Controlled human malaria infection model allows the study of gametocyte biology and dynamics providing novel insights and tools in malaria transmission and elimination efforts.

    Local emergence in Amazonia of Plasmodium falciparum k13 C580Y mutants associated with in vitro artemisinin resistance

    Luana C Mathieu, Horace Cox ... Lise Musset
    The de novo selection of a mutation responsible for Plasmodium falciparum in vitro artemisinin resistance is confirmed in Guyana, making artemisinin combination therapies vulnerable to complete resistance in this region.

    A Plasmodium falciparum MORC protein complex modulates epigenetic control of gene expression through interaction with heterochromatin

    Maneesh Kumar Singh, Victoria Ann Bonnell ... Celia RS Garcia
    Multi-omic analyses reveal that the chromatin-associated microrchidia protein, MORC (PF3D7_1468100), at the blood stage of the human malaria parasite, Plasmodium falciparum, interacts with a range of nuclear proteins.

    Mapping immune variation and var gene switching in naive hosts infected with Plasmodium falciparum

    Kathryn Milne, Alasdair Ivens ... Philip J Spence
    Parasite variants associated with severe malaria do not have an intrinsic growth or survival advantage in vivo, which indicates that a change in host environment is required for their selection.

    A novel computational pipeline for var gene expression augments the discovery of changes in the Plasmodium falciparum transcriptome during transition from in vivo to short-term in vitro culture

    Clare Andradi-Brown, Jan Stephan Wichers-Misterek ... Anna Bachmann
    An enhanced bioinformatic pipeline to quantify Plasmodium falciparum core gene and polymorphic var gene expression revealed changes occurring during early culture adaptation of parasites from naturally infected individuals.

    Genome-wide regulatory dynamics of translation in the Plasmodium falciparum asexual blood stages

    Florence Caro, Vida Ahyong ... Joseph L DeRisi
    Ribosome profiling has bridged the knowledge gap between transcription and translation during malaria blood stage development and provided a comprehensive gene expression resource for this parasite.

    Cryo-EM structure of the Plasmodium falciparum 80S ribosome bound to the anti-protozoan drug emetine

    Wilson Wong, Xiao-chen Bai ... Sjors HW Scheres
    The molecular mechanism behind how emetine inhibits the ribosome of the human malaria parasite, along with structural details of the complex formed, is revealed at high resolution using cryo-electron microscopy.
