    Predicting mosquito infection from Plasmodium falciparum gametocyte density and estimating the reservoir of infection

    Thomas S Churcher, Teun Bousema ... María-Gloria Basáñez
    Identifying and treating those groups of individuals that are most likely to transmit the malaria parasite to mosquitoes could help to control the spread of the disease.
    1. Microbiology and Infectious Disease

    Coordinated regulation of gene expression in Plasmodium female gametocytes by two transcription factors

    Yuho Murata, Tsubasa Nishi ... Masao Yuda
    Sequential expression of two transcription factors that bind to five- and ten-base female-specific cis-acting elements, respectively, promotes differentiation of Plasmodium female gametocytes.
    1. Microbiology and Infectious Disease

    Quantification of sporozoite expelling by Anopheles mosquitoes infected with laboratory and naturally circulating P. falciparum gametocytes

    Chiara Andolina, Wouter Graumans ... Teun Bousema
    The number of sporozoites expelled by mosquitoes that are infected with lab-cultured or naturally circulating Plasmodium falciparum gametocytes is heterogeneous and associated with the sporozoite load in their salivary glands.
    1. Epidemiology and Global Health

    Predicting the likelihood and intensity of mosquito infection from sex specific Plasmodium falciparum gametocyte density

    John Bradley, Will Stone ... Teun Bousema
    Malaria transmission between human and mosquito depends on the number of male and female gametocytes in the blood.

    Modeling the dynamics of Plasmodium falciparum gametocytes in humans during malaria infection

    Pengxing Cao, Katharine A Collins ... James M McCaw
    A mathematical model of blood-stage infection with Plasmodium falciparum malaria capturing the sexual stage of the parasite life-cycle is validated against human data, providing new insight into human-to-mosquito transmission.

    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.

    Artemisinin exposure at the ring or trophozoite stage impacts Plasmodium falciparum sexual conversion differently

    Harvie P Portugaliza, Shinya Miyazaki ... Alfred Cortés
    Treatment of malaria parasites with the frontline antimalarial drug artemisinin can increase the proportion of parasites that convert into transmission forms.
    1. Cell Biology

    Single-cell RNA-seq reveals hidden transcriptional variation in malaria parasites

    Adam J Reid, Arthur M Talman ... Mara KN Lawniczak
    Plasmodium parasite transcription shifts dramatically along asexual development, and transmission stages variably express important immune evasion genes, suggesting much interesting biology has until now been hidden by bulk analyses.

    Target-agnostic identification of human antibodies to Plasmodium falciparum sexual forms reveals cross-stage recognition of glutamate-rich repeats

    Axelle Amen, Randy Yoo ... Matthijs M Jore
    A naturally acquired human monoclonal antibody recognizes proteins expressed at different stages of the Plasmodium falciparum life cycle through affinity-matured homotypic interactions with glutamate-rich repeats.

    Multiple short windows of calcium-dependent protein kinase 4 activity coordinate distinct cell cycle events during Plasmodium gametogenesis

    Hanwei Fang, Natacha Klages ... Mathieu Brochet
    CDPK4 is a pleiotropic regulator controlling initiation of DNA replication, mitotic spindle assembly and flagellar activation during the early stages of Plasmodium transmission.
