    Hypocretin neuron-specific transcriptome profiling identifies the sleep modulator Kcnh4a

    Laura Yelin-Bekerman, Idan Elbaz ... Lior Appelbaum
    Comprehensive gene profiling of the hypothalamic hypocretin neurons, high resolution imaging and behavioral assays have revealed the molecular signature of these versatile neurons and identified a potassium channel that is required for nighttime sleep.

    Hippo pathway-mediated YAP1/TAZ inhibition is essential for proper pancreatic endocrine specification and differentiation

    Yifan Wu, Kunhua Qin ... Pei Wang
    Loss of YAP1/TAZ expression in the pancreatic endocrine compartment is not a passive consequence of endocrine specification, rather, Hippo pathway-mediated inhibition of YAP1/TAZ in endocrine progenitors is a prerequisite for endocrine specification and differentiation.

    Subtype-specific responses of hKv7.4 and hKv7.5 channels to polyunsaturated fatty acids reveal an unconventional modulatory site and mechanism

    Damon JA Frampton, Koushik Choudhury ... Sara I Liin
    Polyunsaturated fatty acids facilitate or impede Kv7 channel activation, depending on channel subtype and their dominant functional site(s).

    Neuroendocrinology of the lung revealed by single-cell RNA sequencing

    Christin S Kuo, Spyros Darmanis ... Mark A Krasnow
    Single-cell transcriptomic profiling and systematic analysis of pulmonary neuroendocrine cells identifies over 40 hormones and neuropeptides expressed in myriad combinations, and predicts their targets in mouse and human lung, revealing extraordinary sensory and signaling diversity and potential physiological functions.

    Dyshomeostatic modulation of Ca2+-activated K+ channels in a human neuronal model of KCNQ2 encephalopathy

    Dina Simkin, Kelly A Marshall ... Evangelos Kiskinis
    An inducedpluripotent stem cell (iPSC)-based model of KCNQ2-associated developmental epileptic encephalopathy suggests that disease is driven by dyshomeostaic neuronal mechanisms that are downstream of loss of M-current.
