    Mechanism of environmentally driven conformational changes that modulate H-NS DNA-bridging activity

    Ramon A van der Valk et al.
    The DNA-bridging efficiency of H-NS, a genome organising and transcription regulatory protein, is modulated by changes in environmental conditions of the cell, which drive a structural rearrangement of the protein.

    PrkA controls peptidoglycan biosynthesis through the essential phosphorylation of ReoM

    Sabrina Wamp et al.
    Analysis of suppressor mutants led to the identification of a novel signalling pathway that regulates peptidoglycan biosynthesis in Gram-positive bacteria.

    The complex of TRIP-Br1 and XIAP ubiquitinates and degrades multiple adenylyl cyclase isoforms

    Wenbao Hu et al.
    XIAP/TRIP-Br1-mediated degradation of multiple adenylyl cyclase isoforms is a previously unrecognised general mechanism for controlling adenylyl cyclase expression and the homeostasis of cAMP signalling.

    Nanobody-directed targeting of optogenetic tools to study signaling in the primary cilium

    Jan N Hansen et al.
    Trafficking of optogenetic tools to primary cilia using nanobodies allows to study cAMP signaling with spatial and temporal resolution independent of the cell body.

    Inhibition of IRF4 in dendritic cells by PRR-independent and -dependent signals inhibit Th2 and promote Th17 responses

    Jihyung Lee et al.
    Reprogramming of transcription factors by PRR-independent (cAMP) and PRR-dependent (curdlan) signaling induces new dendritic cell subset.

    Bordetella adenylate cyclase toxin is a unique ligand of the integrin complement receptor 3

    Radim Osicka et al.
    A toxin produced by the bacterium Bordetella pertussis preferentially binds to non-activated integrin complement receptor 3 outside of its ligand-binding I-domain and efficiently blocks downstream signaling of the integrin through elevation of cytosolic cAMP.

    LRRC8A is essential for hypotonicity-, but not for DAMP-induced NLRP3 inflammasome activation

    Jack P Green et al.
    Depletion of LRRC8A provides genetic evidence for the importance of Cl- channels in NLRP3 activation.

    Lysosomal membrane glycoproteins bind cholesterol and contribute to lysosomal cholesterol export

    Jian Li, Suzanne R Pfeffer
    LAMP proteins, the major glycoproteins of the lysosome membrane, bind cholesterol directly and specifically, and interact with NPC1 and NPC2 proteins as part of the lysosomal cholesterol export process.

    Immunosuppression via adenosine receptor activation by adenosine monophosphate released from apoptotic cells

    Hiroshi Yamaguchi et al.
    Apoptotic cells release molecules to recruit macrophages, but do not cause inflammation because they also secrete AMP that functions as a ‘calm down’ signal.

    Crystallographic observation of nonenzymatic RNA primer extension

    Wen Zhang et al.
    Time resolved crystal structures reveal the binding of activated monomers to the template, followed by generation of the imidazolium-bridged dinucleotide intermediate, and finally formation of a phosphodiester bond between the primer and the adjacent monomer.
