    Septin/anillin filaments scaffold central nervous system myelin to accelerate nerve conduction

    Julia Patzig et al.
    A newly identified component in the architecture of the axon/myelin-unit – the septin/anillin scaffold – maintains the structure of myelin in the central nervous system, thereby preventing myelin outfoldings.

    Spectral clustering of risk score trajectories stratifies sepsis patients by clinical outcome and interventions received

    Ran Liu et al.
    Spectral clustering applied to risk trajectories of sepsis patients discovered four distinct clusters stratified by risk of septic shock, mortality, and treatments received prior to an abrupt physiological transition.

    Chronic muscle weakness and mitochondrial dysfunction in the absence of sustained atrophy in a preclinical sepsis model

    Allison M Owen et al.
    Sepsis-induced long-term muscle weakness was reproduced using a refined murine model, which was accompanied by mitochondrial dysfunction in the absence of sustained atrophy, suggesting the promise of mitochondria-targeted post-sepsis therapies.

    Myosin III-mediated cross-linking and stimulation of actin bundling activity of Espin

    Haiyang Liu et al.
    The tail domain of Myosin III binds to and cross-links actin bundling protein Espin1 and thus modulates higher order actin bundle structures in cellular processes such as stereocilia and microvilli.

    Identification of specific Tie2 cleavage sites and therapeutic modulation in experimental sepsis

    Temitayo O Idowu et al.
    Matrix metalloprotease (MMP)-14 cleaves Tie2 at three distinct sites within the fibronectin type-III (FN3) domain and its pharmacological blockade inhibits Tie2 pathological shedding to exert barrier protective effects.

    Guanidine hydrochloride reactivates an ancient septin hetero-oligomer assembly pathway in budding yeast

    Courtney R Johnson et al.
    A naturally-occurring small molecule acts as a chemical chaperone in vivo to alter the folding of a budding yeast septin and promote an oligomerization pathway that was lost during evolution.

    The step-wise pathway of septin hetero-octamer assembly in budding yeast

    Andrew Weems, Michael McMurray
    In budding yeast cells, slow monomeric septin GTPase activity and the cytosolic GTP:GDP ratio dictate the relative incorporation of alternative subunits during septin hetero-oligomer assembly, which proceeds by discrete, ordered steps dependent on allostery between interaction interfaces.

    The adipocyte hormone leptin sets the emergence of hippocampal inhibition in mice

    Camille Dumon et al.
    Maternal obesity and excess of the adipocyte hormone leptin delays the emergence of synaptic inhibition in the developing brain mice.

    Dopamine neurons projecting to medial shell of the nucleus accumbens drive heroin reinforcement

    Julie Corre et al.
    Disinhibition of dopamine neurons in the midbrain drives heroin reinforcement, the initial step towards opioid addiction.

    Long-term consequences of the absence of leptin signaling in early life

    Angela M Ramos-Lobo et al.
    A mouse model that grew without functional leptin receptors until adulthood reveals that early defects in leptin signaling lead to permanent metabolic and developmental problems.
