    Development, calibration, and validation of a novel human ventricular myocyte model in health, disease, and drug block

    Jakub Tomek, Alfonso Bueno-Orovio ... Blanca Rodriguez
    A computer model of human cardiomyocyte was produced and validated on independent datasets, overcoming shortcomings of its predecessors, also yielding broadly relevant insights and results on major ionic currents.

    Mild myelin disruption elicits early alteration in behavior and proliferation in the subventricular zone

    Elizabeth A Gould, Nicolas Busquet ... Wendy B Macklin
    Mild myelin disruption leads to early axonal pathology, a novel pathological response in neural stem cells, regionally increased oligodendrocytes and altered behavior.

    Transcriptional heterogeneity of ventricular zone cells in the ganglionic eminences of the mouse forebrain

    Dongjin R Lee, Christopher Rhodes ... Timothy J Petros
    Single-cell sequencing combined with in situ hybridizations reveal dynamic patterns of differentially expressed genes throughout the ventricular and subventricular zone of the embryonic mouse brain, which likely play important roles in cell fate determination.

    Polyunsaturated fatty acid analogues differentially affect cardiac NaV, CaV, and KV channels through unique mechanisms

    Briana M Bohannon, Alicia de la Cruz ... H Peter Larsson
    Polyunsaturated fatty acid analogues show selectivity for different cardiac ion channels, suggesting their potential use for the treatment of different subtypes of Long QT Syndrome.

    Transient hypothyroidism favors oligodendrocyte generation providing functional remyelination in the adult mouse brain

    Sylvie Remaud, Fernando C Ortiz ... Barbara Demeneix
    Production of remyelinating subventricular zone oligodendrocyte progenitors is stimulated by transient abrogation of thyroid hormone signalling in the adult neural stem cell niche.

    Ankyrin-G mediates targeting of both Na+ and KATP channels to the rat cardiac intercalated disc

    Hua-Qian Yang, Marta Pérez-Hernández ... William A Coetzee
    The functional interaction of Na+ and KATP channels at the intercalated disk of cardiomyocytes depends on Ankyrin G and is clinically relevant since KATP channel mutations affect Na+ channel expression.

    Myogenic vasoconstriction requires G12/G13 and LARG to maintain local and systemic vascular resistance

    Ramesh Chennupati, Angela Wirth ... Stefan Offermanns
    Genetic mouse models identify a critical mechanism of myogenic vasoconstriction and reveal the in vivo function of myogenic autoregulation in protecting from organ overperfusion and in maintaining vascular resistance.

    Graded Ca2+/calmodulin-dependent coupling of voltage-gated CaV1.2 channels

    Rose E Dixon, Claudia M Moreno ... Luis F Santana
    The Ca2+-driven functional coupling of CaV1.2 channels is a mechanism of channel memory that may modulate the amplification of Ca2+ influx.

    Clinical phenotypes in acute and chronic infarction explained through human ventricular electromechanical modelling and simulations

    Xin Zhou, Zhinuo Jenny Wang ... Blanca Rodriguez
    Human-based electromechanical simulations reveal electrocardiogram biomarkers are better indicators of pro-arrhythmic substrate after myocardial infarction than ejection fraction.
