    Evidence from a natural experiment that malaria parasitemia is pathogenic in retinopathy-negative cerebral malaria

    Dylan S Small, Terrie E Taylor ... Karl B Seydel
    The sickle cell trait strongly protects against not only retinopathy-positive cerebral malaria but also retinopathy-negative cerebral malaria, providing evidence that malarial parasites also contribute to retinopathy-negative cerebral malaria and are not innocent bystanders.

    Comparative transcriptomic analysis reveals translationally relevant processes in mouse models of malaria

    Athina Georgiadou, Claire Dunican ... Aubrey J Cunnington
    Comparative transcriptomics of whole blood can be used to evaluate the systemic host response and its concordance between human and mouse malaria and aid the selection of appropriate models for translational malaria research.

    Full-length Plasmodium falciparum myosin A and essential light chain PfELC structures provide new anti-malarial targets

    Dihia Moussaoui, James P Robblee ... Anne Houdusse
    The structure of full-length myosin A provides some hints about its atypical mechanism, and reveals that the light chain PfELC is a target to block malaria pathogenesis.

    The Plasmodium falciparum rhoptry protein RhopH3 plays essential roles in host cell invasion and nutrient uptake

    Emma S Sherling, Ellen Knuepfer ... Christiaan van Ooij
    The rhoptry protein RhopH3 is crucial for the invasion and growth of the malaria parasite and disruption of it provides insight into the binding of the parasite to the host red blood cell and into the formation of new import pathways.

    Common virulence gene expression in adult first-time infected malaria patients and severe cases

    J Stephan Wichers, Gerry Tonkin-Hill ... Anna Bachmann
    Parasites with pathogenic variant surface antigens are common in adult malaria patients with a naive immune status.

    BIRC6 modifies risk of invasive bacterial infection in Kenyan children

    James J Gilchrist, Silvia N Kariuki ... Thomas N Williams
    Defining the probability of bacterial disease among children with severe malaria allows the integration of bacteraemia and severe malaria genome-wide association study data, identifying a novel risk locus for invasive bacterial disease.

    A coordinated transcriptional switching network mediates antigenic variation of human malaria parasites

    Xu Zhang, Francesca Florini ... Kirk W Deitsch
    Malaria parasites avoid destruction by their host's immune response through systematic and coordinated expression switching between members of a network of variant antigen-encoding genes, a process that is mediated by a uniquely conserved gene called var2csa.

    Shed EBA-175 mediates red blood cell clustering that enhances malaria parasite growth and enables immune evasion

    May M Paing, Nichole D Salinas ... Niraj H Tolia
    Plasmodium falciparum invasion protein EBA-175, once shed from the parasite surface post invasion, facilitates RBC clustering and enhances parasite growth while simultaneously enabling parasite immune evasion of host neutralizing antibodies.

    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.

    Total parasite biomass but not peripheral parasitaemia is associated with endothelial and haematological perturbations in Plasmodium vivax patients

    João L Silva-Filho, João CK Dos-Santos ... Fabio TM Costa
    Data exploring host and parasite signatures in the peripheral blood indicate that total parasite biomass is a better predictor of P. vivax-induced host responses and pathogenesis than peripheral parasitemia.
