    UNC93B1 mediates differential trafficking of endosomal TLRs

    Bettina L Lee et al.
    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.

    IgM and IgD B cell receptors differentially respond to endogenous antigens and control B cell fate

    Mark Noviski et al.
    Self-reactive B cells downregulate the IgM but not the IgD B cell receptor, and this serves as a critical tolerance mechanism because IgD is less sensitive to bona fide endogenous antigens than IgM.

    Identification of a Munc13-sensitive step in chromaffin cell large dense-core vesicle exocytosis

    Kwun Nok M Man et al.
    Munc13 proteins are key determinants of large dense-core vesicle (LDCV)-dependent catecholamine release in chromaffin cells.

    Ascorbic acid supports ex vivo generation of plasmacytoid dendritic cells from circulating hematopoietic stem cells

    Anders Laustsen et al.
    Probing of various culture conditions leads to fundamental advances in ex vivo production of plasmacytoid dendritic cells for use in immunotherapy.

    B cell receptor and Toll-like receptor signaling coordinate to control distinct B-1 responses to both self and the microbiota

    Lieselotte SM Kreuk et al.
    Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.

    Rapid regulation of vesicle priming explains synaptic facilitation despite heterogeneous vesicle:Ca2+ channel distances

    Janus RL Kobbersmed et al.
    Heterogeneous distances between vesicles and Ca2+-channels make synapses prone to short-term depression, however, Ca2+-dependent increases in the number of release-ready vesicles supports facilitation even with broadly distributed vesicle:Ca2+-channel distances.

    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.

    FRMD8 promotes inflammatory and growth factor signalling by stabilising the iRhom/ADAM17 sheddase complex

    Ulrike Künzel et al.
    The protein FRMD8 binds to iRhom and thereby stabilises the iRhom/ADAM17 complex, which is the primary trigger of inflammatory signalling.

    Membrane bridging by Munc13-1 is crucial for neurotransmitter release

    Bradley Quade et al.
    Cryo-electron tomography, reconstitution, and electrophysiological data show that a fundamental function of Munc13-1 is to bridge synaptic vesicles to the presynaptic plasma membrane.
