A cerebellar learning model of vestibulo-ocular reflex adaptation in wild-type and mutant mice.
(The Journal of neuroscience : the official journal of the Society for Neuroscience, 2014-05)Mechanisms of cerebellar motor learning are still poorly understood. The standard Marr-Albus-Ito theory posits that learning involves plasticity at the parallel fiber to Purkinje cell synapses under control of the climbing ... -
A Novel Mouse Model of Diffuse Intrinsic Pontine Glioma Initiated in Pax3-Expressing Cells.
(Neoplasia, 2016-01)Diffuse intrinsic pontine glioma (DIPG) is a rare and incurable brain tumor that arises predominately in children and involves the pons, a structure that along with the midbrain and medulla makes up the brainstem. We have ... -
A Peptide Uncoupling BDNF Receptor TrkB from Phospholipase Cγ1 Prevents Epilepsy Induced by Status Epilepticus.
(Neuron, 2015-11-04)The BDNF receptor tyrosine kinase, TrkB, underlies nervous system function in both health and disease. Excessive activation of TrkB caused by status epilepticus promotes development of temporal lobe epilepsy (TLE), revealing ... -
Activation of Rod Input in a Model of Retinal Degeneration Reverses Retinal Remodeling and Induces Formation of Functional Synapses and Recovery of Visual Signaling in the Adult Retina.
(The Journal of neuroscience : the official journal of the Society for Neuroscience, 2019-08)A major cause of human blindness is the death of rod photoreceptors. As rods degenerate, synaptic structures between rod and rod bipolar cells disappear and the rod bipolar cells extend their dendrites and occasionally make ... -
Activation of the ATF6 (Activating Transcription Factor 6) Signaling Pathway in Neurons Improves Outcome After Cardiac Arrest in Mice.
(Journal of the American Heart Association, 2021-06-11)Background Ischemia/reperfusion injury impairs proteostasis, and triggers adaptive cellular responses, such as the unfolded protein response (UPR), which functions to restore endoplasmic reticulum homeostasis. After cardiac ... -
Alterations in cardiac adrenergic signaling and calcium cycling differentially affect the progression of cardiomyopathy.
(J Clin Invest, 2001-04)The medical treatment of chronic heart failure has undergone a dramatic transition in the past decade. Short-term approaches for altering hemodynamics have given way to long-term, reparative strategies, including beta-adrenergic ... -
An immunoglobulin C kappa-reactive single chain antibody fusion protein induces tolerance through receptor editing in a normal polyclonal immune system.
(J Exp Med, 2005-03-07)Understanding immune tolerance mechanisms is a major goal of immunology research, but mechanistic studies have generally required the use of mouse models carrying untargeted or targeted antigen receptor transgenes, which ... -
Angiopoietin receptor TEK mutations underlie primary congenital glaucoma with variable expressivity.
(The Journal of clinical investigation, 2016-07)Primary congenital glaucoma (PCG) is a devastating eye disease and an important cause of childhood blindness worldwide. In PCG, defects in the anterior chamber aqueous humor outflow structures of the eye result in elevated ... -
APOL1-G0 or APOL1-G2 Transgenic Models Develop Preeclampsia but Not Kidney Disease.
(Journal of the American Society of Nephrology : JASN, 2016-12)APOL1 risk variants are associated with kidney disease in blacks, but the mechanisms of renal injury associated with APOL1 risk variants are unknown. Because APOL1 is unique to humans and some primates, we created transgenic ... -
APOL1-G0 protects podocytes in a mouse model of HIV-associated nephropathy.
(PloS one, 2019-01)African polymorphisms in the gene for Apolipoprotein L1 (APOL1) confer a survival advantage against lethal trypanosomiasis but also an increased risk for several chronic kidney diseases (CKD) including HIV-associated nephropathy ... -
Augmentation of cardiac contractility mediated by the human beta(3)-adrenergic receptor overexpressed in the hearts of transgenic mice.
(Circulation, 2001-11-13)BACKGROUND: Stimulation of beta(1)- and beta(2)-adrenergic receptors (ARs) in the heart results in positive inotropy. In contrast, it has been reported that the beta(3)AR is also expressed in the human heart and that its ... -
Beta-arrestin-2 regulates the development of allergic asthma.
(J Clin Invest, 2003-08)Asthma is a chronic inflammatory disorder of the airways that is coordinated by Th2 cells in both human asthmatics and animal models of allergic asthma. Migration of Th2 cells to the lung is key to their inflammatory function ... -
Beta-arrestin-mediated beta1-adrenergic receptor transactivation of the EGFR confers cardioprotection.
(J Clin Invest, 2007-09)Deleterious effects on the heart from chronic stimulation of beta-adrenergic receptors (betaARs), members of the 7 transmembrane receptor family, have classically been shown to result from Gs-dependent adenylyl ... -
Black cohosh increases metastatic mammary cancer in transgenic mice expressing c-erbB2.
(Cancer research, 2008-10)Black cohosh is an herbal extract that is often used as an alternative to estrogen-based replacement therapies to treat hot flushes that frequently accompany the transition to menopause. Although cancer-free women as well ... -
Calcineurin activation causes retinal ganglion cell degeneration.
(Mol Vis, 2012)PURPOSE: We previously reported that calcineurin, a Ca(2+)/calmodulin-dependent serine/threonine phosphatase, is activated and proposed that it participates in retinal ganglion cell (RGC) apoptosis in two rodent ... -
Cardiac beta ARK1 inhibition prolongs survival and augments beta blocker therapy in a mouse model of severe heart failure.
(Proc Natl Acad Sci U S A, 2001-05-08)Chronic human heart failure is characterized by abnormalities in beta-adrenergic receptor (betaAR) signaling, including increased levels of betaAR kinase 1 (betaARK1), which seems critical to the pathogenesis of the disease. ... -
Characterization of basal pseudopod-like processes in ileal and colonic PYY cells.
(J Mol Histol, 2011-02)The peptide tyrosine tyrosine (PYY) is produced and secreted from L cells of the gastrointestinal mucosa. To study the anatomy and function of PYY-secreting L cells, we developed a transgenic PYY-green fluorescent protein ... -
Chemogenetics-mediated acute inhibition of excitatory neuronal activity improves stroke outcome.
(Experimental neurology, 2020-04)<h4>Background and purpose</h4>Ischemic stroke significantly perturbs neuronal homeostasis leading to a cascade of pathologic events causing brain damage. In this study, we assessed acute stroke outcome after chemogenetic ... -
Chronic oxidative stress promotes GADD34-mediated phosphorylation of the TAR DNA-binding protein TDP-43, a modification linked to neurodegeneration.
(The Journal of biological chemistry, 2018-01)Oxidative and endoplasmic reticulum (ER) stresses are hallmarks of the pathophysiology of ALS and other neurodegenerative diseases. In these stresses, different kinases phosphorylate eukaryotic initiation factor eIF2α, enabling ... -
