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

    May M Paing et al.
    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.

    Structure of the malaria vaccine candidate antigen CyRPA and its complex with a parasite invasion inhibitory antibody

    Paola Favuzza et al.
    The structure of the promising malaria blood-stage vaccine candidate antigen PfCyRPA and the characterization of a protective epitope are facilitating research on its essential role in parasite invasion, and will guide future epitope-focused vaccine design.

    RalB directly triggers invasion downstream Ras by mobilizing the Wave complex

    Giulia Zago et al.
    By moving from correlations to causality in cancer signal transduction using optogenetics, the sufficiency of RalB activation to trigger invasion and the underlying molecular mechanisms were established.

    p27Kip1 promotes invadopodia turnover and invasion through the regulation of the PAK1/Cortactin pathway

    Pauline Jeannot et al.
    p27Kip1 directly controls invadopodia turnover by promoting the interaction of PAK1 with Cortactin, which induces Cortactin phosphorylation, invadopodia disassembly and facilitates invasion through extracellular matrix.

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

    Daisuke Ito et al.
    Gene knockdowns reveal that the conserved RhopH protein complex functions in both host cell invasion and channel-mediated nutrient uptake in malaria.

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

    Xavier Sisquella et al.
    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.

    A druggable secretory protein maturase of Toxoplasma essential for invasion and egress

    Sunil Kumar Dogga et al.
    An aspartyl protease is essential for the lytic cycle of Toxoplasma gondii and is involved in the maturation of proteins critical for invasion and egress, and it can be targeted selectively with an ethylamine scaffold based peptidomimetic inhibitor.

    A conserved major facilitator superfamily member orchestrates a subset of O-glycosylation to aid macrophage tissue invasion

    Katarina Valoskova et al.
    T antigen glycosylation, which marks metastatic cancer cells, is modulated on a small set of proteins by a conserved multipass transmembrane protein to allow tissue invasion by Drosophila macrophages.

    G-protein-coupled receptor signaling and polarized actin dynamics drive cell-in-cell invasion

    Vladimir Purvanov et al.
    siRNA knockdown experiments reveal in detail the signaling pathway that controls cytoskeletal function during cell-in-cell invasion.

    TP53 drives invasion through expression of its Δ133p53β variant

    Gilles Gadea et al.
    Clinical analysis corroborated with experimental data demonstrate that Δ133p53β, a naturally occurring isoform of p53 protein, induces a pro-metastatic program and is a clinical indicator of metastasis, independently of TP53 mutation status.
