    Profiling of myristoylation in Toxoplasma gondii reveals an N-myristoylated protein important for host cell penetration

    Malgorzata Broncel, Caia Dominicus ... Moritz Treeck
    Myristoylation of a secreted protein, identified in a global myristoylation analysis of the eukaryotic parasite Toxoplasma gondii, is important for host cell invasion.

    Differential requirements for cyclase-associated protein (CAP) in actin-dependent processes of Toxoplasma gondii

    Alex Hunt, Matthew Robert Geoffrey Russell ... Moritz Treeck
    Partially overlapping functions of a limited subset of actin binding proteins allow the parasite Toxoplasma gondii to achieve actin regulation required for complex cellular processes.

    A single-parasite transcriptional atlas of Toxoplasma Gondii reveals novel control of antigen expression

    Yuan Xue, Terence C Theisen ... John C Boothroyd
    Single-cell RNA-sequencing resolves the transcriptional landscape of asexual development in Toxoplasma gondii, revealing concerted genetic programs to Plasmodiumfalciparum and a novel transcriptional factor that controls antigen switching.

    Dissection of the in vitro developmental program of Hammondia hammondi reveals a link between stress sensitivity and life cycle flexibility in Toxoplasma gondii

    Sarah L Sokol, Abby S Primack ... Jon P Boyle
    A derived stress response trait may have contributed to the emergence of a globally dominant and promiscuous parasite.

    An aspartyl protease defines a novel pathway for export of Toxoplasma proteins into the host cell

    Michael J Coffey, Brad E Sleebs ... Christopher J Tonkin
    The Toxoplasma parasite requires an enzyme called ASP5 to cleave proteins for export into host cells.

    Overexpression screen of interferon-stimulated genes identifies RARRES3 as a restrictor of Toxoplasma gondii infection

    Nicholas Rinkenberger, Michael E Abrams ... L David Sibley
    Overexpression of interferon-stimulated genes revealed a role for RARRES3 in restricting growth of Toxoplasma gondii by inducing early egress from human cells.

    Injection with Toxoplasma gondii protein affects neuron health and survival

    Oscar A Mendez, Emiliano Flores Machado ... Anita A Koshy
    Multi-level profiling of Toxoplasma gondii-injected neurons identifies brain regions and neuron subtype predilections as well as the effect of Toxoplasma interactions on neuron physiology and health.

    Apical annuli are specialised sites of post-invasion secretion of dense granules in Toxoplasma

    Sara Chelaghma, Huiling Ke ... Ross F Waller
    Apicomplexan parasites secrete proteins to manipulate their hosts from sub-apical openings in their cell pellicle that are distinct from the apical complex from where invasion factors are secreted.

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

    Sunil Kumar Dogga, Budhaditya Mukherjee ... Dominique Soldati-Favre
    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.

    SPARK regulates AGC kinases central to the Toxoplasma gondii asexual cycle

    Alice L Herneisen, Michelle L Peters ... Sebastian Lourido
    Genetic and proteomic analyses reveal that the SPARK kinase, which is a regulator of key life-cycle transitions in the parasite Toxoplasma gondii, complexes with an elongin-like protein to regulate several important AGC-family kinases.
