Here, we review the current knowledge regarding Nrgs, explaining their roles in transducing signals between the heart’s microvasculature and cardiomyocytes. We highlight intriguing areas being investigated for developing new, Nrg-mediated strategies to heal the heart in acquired and congenital heart diseases, and note avenues for future research. ----------------------------------------------------------------------------------------------------------------------------------------------------------- Keywords Neuregulin Heart Heterocellular communication ErbB -----------------------------------------------------------------------------------------------------------------------------------------------------------† † † This article is part of the Spotlight Issue on: Heterocellular signalling -
The Epidermal Growth Factor Receptor Family As a Central Element for Cellular Signal Transduction and Diversification
Endocrine-Related Cancer (2001) 8 11–31 The epidermal growth factor receptor family as a central element for cellular signal transduction and diversification N Prenzel, O M Fischer, S Streit, S Hart and A Ullrich Max-Planck Institut fu¨r Biochemie, Department of Molecular Biology, Am Klopferspitz 18A, 82152 Martinsried, Germany (Requests for offprints should be addressed to A Ullrich; Email: [email protected]) Abstract Homeostasis of multicellular organisms is critically dependent on the correct interpretation of the plethora of signals which cells are exposed to during their lifespan. Various soluble factors regulate the activation state of cellular receptors which are coupled to a complex signal transduction network that ultimately generates signals defining the required biological response. The epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases represents both key regulators of normal cellular development as well as critical players in a variety of pathophysiological phenomena. The aim of this review is to give a broad overview of signal transduction networks that are controlled by the EGFR superfamily of receptors in health and disease and its application for target-selective therapeutic intervention. Since the EGFR and HER2 were recently identified as critical players in the transduction of signals by a variety of cell surface receptors, such as G-protein-coupled receptors and integrins, our special focus is the mechanisms and significance of the interconnectivity between heterologous signalling systems.

ABSTRACT The dopamine D1-D2 receptor agonist, R-apomorphine, has been shown to be neuroprotective in different models of Parkinson’s disease. Different mechanisms of action for this effect have been proposed, but not verified in the striatal 6-hydroxydopamine rat model. In this study, the expression of a set of genes involved in 1) signaling, 2) growth and differentiation, 3) neuronal regeneration and survival, 4) apoptosis and 5) inflammation in the striatum was measured after a subchronic R-apomorphine treatment (10 mg/kg/day, subcutaneously, during 11 days) in the striatal 6-hydroxy- dopamine rat model. The expression of 84 genes was analysed by using the rat neurotrophins and receptors RT2 Pro- filer™ PCR array. The neuroprotective effects of R-apomorphine in the striatal 6-hydroxydopamine model were con- firmed by neurochemical and behavioural analysis. -

The so-called brown adipokines or ‘batokines’ may play an f brown adipokine autocrine role, which may either be positive or negative, in the thermogenic function f batokine of brown adipocytes. Additionally, there is a growing recognition of the signalling f thermogenesis molecules released by brown adipocytes that target sympathetic nerve endings (such as neuregulin-4 and S100b protein), vascular cells (e.g., bone morphogenetic protein-8b), and immune cells (e.g., C-X-C motif chemokine ligand-14) to promote the tissue remodelling associated with the adaptive BAT recruitment in response to thermogenic stimuli. Moreover, existing indications of an endocrine role of BAT are being confirmed through the release of brown adipokines acting on other distant tissues and organs; a recent example is the recognition that BAT-secreted fibroblast growth factor-21 and myostatin target the heart and skeletal muscle, respectively. -

NMDA Receptors Regulate Neuregulin 2 Binding to ER-PM Junctions and Ectodomain Release
Molecular Neurobiology (2019) 56:8345–8363 https://doi.org/10.1007/s12035-019-01659-w NMDA Receptors Regulate Neuregulin 2 Binding to ER-PM Junctions and Ectodomain Release Detlef Vullhorst1 & Andres Buonanno1 Received: 29 March 2019 /Accepted: 20 May 2019 /Published online: 25 June 2019 # This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2019 Abstract Unprocessed pro-neuregulin 2 (pro-NRG2) accumulates on neuronal cell bodies at junctions between the endoplasmic reticulum and plasma membrane (ER-PM junctions). NMDA receptors (NMDARs) trigger NRG2 ectodomain shedding from these sites followed by activation of ErbB4 receptor tyrosine kinases, and ErbB4 signaling cell-autonomously downregulates intrinsic excitability of GABAergic interneurons by reducing voltage-gated sodium channel currents. NMDARs also promote dispersal of Kv2.1 clusters from ER-PM junctions and cause a hyperpolarizing shift in its voltage-dependent channel activation, suggesting that NRG2/ErbB4 and Kv2.1 work together to regulate intrinsic interneuron excitability in an activity-dependent manner. Here we explored the cellular processes underlying NMDAR-dependent NRG2 shedding in cultured rat hippocampal neurons. We report that NMDARs control shedding by two separate but converging mechanisms. First, NMDA treatment disrupts binding of pro-NRG2 to ER-PM junctions by post-translationally modifying conserved Ser/Thr residues in its intracellular domain. Second, using a mutant NRG2 protein that cannot be modified at these residues and that fails to accumulate at ER-PM junctions, we demonstrate that NMDARs also directly promote NRG2 shedding by ADAM-type metalloproteinases. Using pharmacological and shRNA-mediated knockdown, and metalloproteinase overexpression, we unexpectedly find that ADAM10, but not ADAM17/TACE, is the major NRG2 sheddase acting downstream of NMDAR activation. -

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in
