    Structural mechanisms of phospholipid activation of the human TPC2 channel

    Ji She, Weizhong Zeng ... Youxing Jiang
    Cryo-EM structures of human TPC2 channel in the ligand-bound and apo states reveal the structural mechanism of PI(3,5)P2 lipid regulated gating of TPC2.

    Sterol derivative binding to the orthosteric site causes conformational changes in an invertebrate Cys-loop receptor

    Steven De Gieter, Casey I Gallagher ... Rouslan G Efremov
    Cryo-EM structures of Cys-loop receptor Alpo4 from the thermophilic worm Alvinella pompejana show that a sterol derivative CHAPS binds in and outside of its orthosteric binding site and induces a quaternary twist.

    Clearance of beta-amyloid is facilitated by apolipoprotein E and circulating high-density lipoproteins in bioengineered human vessels

    Jerome Robert, Emily B Button ... Cheryl L Wellington
    Modelling beta-amyloid deposition in bioengineered human vessels represents a notable advance to further investigate the role of the vasculature in Alzheimer's disease.

    Evolution of (p)ppGpp-HPRT regulation through diversification of an allosteric oligomeric interaction

    Brent W Anderson, Kuanqing Liu ... Jue D Wang
    The signaling ligand (p)ppGpp regulates the enzyme HPRT across species by binding to a novel class of conserved motif, yet its specificity is allosterically altered through evolution of enzyme oligomerization.

    Structure analyses reveal a regulated oligomerization mechanism of the PlexinD1/GIPC/myosin VI complex

    Guijun Shang, Chad A Brautigam ... Xuewu Zhang
    PlexinD1 binding releases GIPC autoinhibition, leading to formation of high-order oligomers of the GIPC/myosin VI complex.

    Structural insights into the Ca2+-dependent gating of the human mitochondrial calcium uniporter

    Yan Wang, Yan Han ... Youxing Jiang
    Cryo-EM structures of human MCU-EMRE-MICU1-MICU2 complex in the apo and Ca2+-bound states reveal how MICU1 and MICU2 impart their gating function to the mitochondrial calcium uniporter.

    Apolipoprotein M-bound sphingosine-1-phosphate regulates blood–brain barrier paracellular permeability and transcytosis

    Mette Mathiesen Janiurek, Rana Soylu-Kucharz ... Martin Lauritzen
    Shortage of blood-borne apolipoprotein-M–bound sphingosine-1-phosphate, which accompanies various brain disorders, causes paracellular leak and increase in transcytosis at the blood–brain barrier, which can be reversed, thus is of clinical relevance.

    Mechanism of dimer selectivity and binding cooperativity of BRAF inhibitors

    Joseph Clayton, Aarion Romany ... Jana Shen
    BRAF inhibitors achieve monomer or dimer selectivity through their ability to modulate dimerization and allosteric communication.

    FGF21 protects against hepatic lipotoxicity and macrophage activation to attenuate fibrogenesis in nonalcoholic steatohepatitis

    Cong Liu, Milena Schönke ... Patrick CN Rensen
    Fibroblast growth factor 21 blocks hepatic lipid influx and accumulation, prevents Kupffer cell activation, and inhibits the formation of hepatic lipid- and scar-associated macrophages, thereby likely inhibiting fibrogenesis in nonalcoholic steatohepatitis in humanized APOE*3-Leiden.CETP mice.

    Curcumin promotes AApoAII amyloidosis and peroxisome proliferation in mice by activating the PPARα signaling pathway

    Jian Dai, Ying Li ... Keiichi Higuchi
    Curcumin regulates gene expression via PPARa activation and exhibits biological activities involved in amyloidosis, peroxisome proliferation, lipid metabolism, and hepatocyte hypertrophy.
