    Estradiol elicits distinct firing patterns in arcuate nucleus kisspeptin neurons of females through altering ion channel conductances

    Jian Qiu, Margaritis Voliotis ... Martin J Kelly
    Kiss1ARH neurons transition from synchronous to burst firing under preovulatory levels of E2, causing a shift from peptidergic to glutamatergic transmission that drives the GnRH surge through enhanced glutamate neurotransmission.

    Temporal proteomic analysis of HIV infection reveals remodelling of the host phosphoproteome by lentiviral Vif variants

    Edward JD Greenwood, Nicholas J Matheson ... Paul J Lehner
    A comprehensive whole cell proteomic map describing expression time courses of >6,500 viral and cellular proteins during HIV infection identifies Vif-dependent antagonism of key cellular phosphatase PP2A.

    Regulation of pulmonary surfactant by the adhesion GPCR GPR116/ADGRF5 requires a tethered agonist-mediated activation mechanism

    James P Bridges, Caterina Safina ... Marie-Gabrielle Ludwig
    Mutagenesis and activity assays in vitro and in vivo identify residues in the tethered agonist of GPR116, as well as those within the extracellular loops, that are critical for mediating the response to the tethered agonist.
