    Sequence specific detection of bacterial 23S ribosomal RNA by TLR13

    Xiao-Dong Li, Zhijian J Chen
    A pattern recognition receptor called toll-like receptor 13 detects pathogens in a manner that is different to that seen in other pathogen sensors.

    Reciprocal virulence and resistance polymorphism in the relationship between Toxoplasma gondii and the house mouse

    Jingtao Lilue et al.
    Mechanisms that enable wild mice to survive infection with strains of the Toxoplasma gondii parasite virulent enough to kill laboratory mice offer an explanation for how these parasites have been able to persist in the mouse population.

    Abscisic acid dynamics in roots detected with genetically encoded FRET sensors

    Alexander M Jones et al.
    Fluorescent sensors for the hormone abscisic acid have been developed using a high-throughput platform, and used to monitor hormone dynamics in plant roots and leaves.

    An atomic-resolution view of neofunctionalization in the evolution of apicomplexan lactate dehydrogenases

    Jeffrey I Boucher et al.
    The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.

    Phenotypic complementation of genetic immunodeficiency by chronic herpesvirus infection

    Donna A MacDuff et al.
    HOIL-1 deficiency in mice results in a severe immunodeficiency that is effectively complemented by chronic infection with a murine gamma-herpesvirus.

    Cytotoxic activities of CD8+ T cells collaborate with macrophages to protect against blood-stage murine malaria

    Takashi Imai et al.
    The cytotoxicity exerted by CD8+ T cells against parasitized erythroblasts helps to protect against blood-stage malaria by making parasitized cells susceptible to phagocytosis.

    Chromerid genomes reveal the evolutionary path from photosynthetic algae to obligate intracellular parasites

    Yong H Woo et al.
    Analysis of chromerid algal genomes reveals how apicomplexans have evolved from free-living algae into successful eukaryotic parasites via massive losses and re-inventing functional roles of genes.

    An extrafollicular pathway for the generation of effector CD8+ T cells driven by the proinflammatory cytokine, IL-12

    Suhagi Shah et al.
    Proliferation and differentiation of CD8+ T cells into terminal effectors occurs in the marginal zone and red pulp, and is promoted by IL-12 through direct and indirect mechanisms.

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

    Michael J Coffey et al.
    The Toxoplasma parasite requires an enzyme called ASP5 to cleave proteins for export into host cells.
