    Erythrocyte CD55 mediates the internalization of Plasmodium falciparum parasites

    Bikash Shakya, Saurabh D Patel ... Elizabeth S Egan
    The strain-transcendent receptor CD55 plays a distinct functional role relative to other known receptors for Plasmodium falciparum invasion of human erythrocytes, indicating it may present a vulnerable target for intervention.

    Plasmodium falciparum ligand binding to erythrocytes induce alterations in deformability essential for invasion

    Xavier Sisquella, Thomas Nebl ... Alan F Cowman
    Interaction of P. falciparum with the erythrocyte activates a phosphorylation cascade altering the viscoelastic properties of this area of the host membrane conditioning it for successful invasion.

    Malaria parasites use a soluble RhopH complex for erythrocyte invasion and an integral form for nutrient uptake

    Marc A Schureck, Joseph E Darling ... Sanjay A Desai
    A high-resolution structure reveals how the RhopH complex traffics within Plasmodium-infected human erythrocytes to serve divergent, essential functions.

    Cavefish cope with environmental hypoxia by developing more erythrocytes and overexpression of hypoxia-inducible genes

    Corine M van der Weele, William R Jeffery
    Astyanax mexicanus cavefish cope with hypoxic environments by expanding embryonic hematopoietic domains, increasing the capacity for erythrocyte development, and constitutive overexpression of hypoxia-inducible genes.

    Structural basis for inhibition of erythrocyte invasion by antibodies to Plasmodium falciparum protein CyRPA

    Lin Chen, Yibin Xu ... Alan F Cowman
    The crystal structures of the key vaccine candidate CyRPA alone and in complex with antibody Fab fragment was solved and this will be important information for designing a vaccine.

    Impaired iron recycling from erythrocytes is an early hallmark of aging

    Patryk Slusarczyk, Pratik Kumar Mandal ... Katarzyna Mleczko-Sanecka
    A decline in iron-recycling functions of the splenic red pulp macrophages early during aging is driven by iron loading and involves their damage and a loss in red blood cell clearance capacity.

    Erythrocyte invasion-neutralising antibodies prevent Plasmodium falciparum RH5 from binding to basigin-containing membrane protein complexes

    Abhishek Jamwal, Cristina F Constantin ... Matthew K Higgins
    The most effective growth-neutralising antibodies which target the PfRH5 protein from a malaria parasite function by preventing the parasite from binding to basigin-containing membrane protein complexes on human erythrocytes.

    An essential dual-function complex mediates erythrocyte invasion and channel-mediated nutrient uptake in malaria parasites

    Daisuke Ito, Marc A Schureck, Sanjay A Desai
    Gene knockdowns reveal that the conserved RhopH protein complex functions in both host cell invasion and channel-mediated nutrient uptake in malaria.

    Synergy in anti-malarial pre-erythrocytic and transmission-blocking antibodies is achieved by reducing parasite density

    Ellie Sherrard-Smith, Katarzyna A Sala ... Andrew M Blagborough
    Combining pre-erythrocytic and transmission blocking antibodies enhances the overall control and potential elimination of malaria within both mosquito and vertebrate populations.

    Plasmodium falciparum parasites deploy RhopH2 into the host erythrocyte to obtain nutrients, grow and replicate

    Natalie A Counihan, Scott A Chisholm ... Tania F de Koning-Ward
    Plasmodium parasites secrete RhopH2 from the rhoptry organelle into their host red blood cell to facilitate the uptake of essential nutrients required for parasite replication and survival.
