    UNC93B1 mediates differential trafficking of endosomal TLRs

    Bettina L Lee, Joanne E Moon ... Gregory M Barton
    A transmembrane protein uses distinct mechanisms to regulate the movement of specific toll-like receptors-key immune system components involved in detecting pathogens-to their final locations inside cells.

    Nuclear receptor LRH-1/NR5A2 is required and targetable for liver endoplasmic reticulum stress resolution

    Jennifer L Mamrosh, Jae Man Lee ... David D Moore
    LRH-1/NR5A2 responds to ER stress by inducing a novel pathway that is required for stress resolution in mice and can be targeted by LRH-1 agonists.

    The glucuronyltransferase B4GAT1 is required for initiation of LARGE-mediated α-dystroglycan functional glycosylation

    Tobias Willer, Kei-ichiro Inamori ... Kevin P Campbell
    Post-phosphoryl modification of α-dystroglycan requires the glucuronyltransferase B4GAT1; this enzyme synthesizes the acceptor glycan that serves as a primer for the glycosyltransferase LARGE to synthesize the laminin-binding glycan.

    The sheddase ADAM10 is a potent modulator of prion disease

    Hermann C Altmeppen, Johannes Prox ... Markus Glatzel
    A lack of ADAM10-mediated shedding increases prion protein levels at the plasma membrane and promotes the generation of pathological prion proteins, which accelerates prion disease in mice.

    Herpes simplex type 2 virus deleted in glycoprotein D protects against vaginal, skin and neural disease

    Christopher Petro, Pablo A González ... William R Jacobs Jr
    An attenuated Herpes simplex type 2 virus deleted in glycoprotein D can be used as an effective vaccine to provide robust transferable humoral immunity and complete protection in murine intravaginal and skin infection models.

    Fucosylation and protein glycosylation create functional receptors for cholera toxin

    Amberlyn M Wands, Akiko Fujita ... Jennifer J Kohler
    Cholera intoxication of human colonic epithelial cells is dependent on recognition of protein glycosylation and fucosylation, not exclusively on ganglioside recognition as proposed previously.

    Toxoplasma gondii peptide ligands open the gate of the HLA class I binding groove

    Curtis McMurtrey, Thomas Trolle ... William Hildebrand
    T. gondii infection alters how peptide ligands are presented to the immune system by inducing a previously unreported structural change in Human Leukocyte Antigens (HLAs).

    Opposing roles of nuclear receptor HNF4α isoforms in colitis and colitis-associated colon cancer

    Karthikeyani Chellappa, Poonamjot Deol ... Frances M Sladek
    Proper gut health depends on the balance between two naturally occurring variants of a transcription factor in the colon.

    Golgi self-correction generates bioequivalent glycans to preserve cellular homeostasis

    Haik Mkhikian, Christie-Lynn Mortales ... Michael Demetriou
    Structurally dissimilar N-glycans can be functionally equivalent, and are produced via a self-correcting feature of the Golgi.

    Thrombospondin expression in myofibers stabilizes muscle membranes

    Davy Vanhoutte, Tobias G Schips ... Jeffery D Molkentin
    Thrombospondin proteins regulate vesicular trafficking of integrins and other membrane attachment complex proteins to the plasma membrane of skeletal muscle, which provides greater stability and resistance to muscular dystrophy.
