Gβ3 is required for normal light ON responses and synaptic maintenanceAnuradha Dhingra
Department of Neuroscience, University of Pennsylvania, Philadelphia, Pennsylvania 19104, USA
J Neurosci 32:11343-55. 2012..Furthermore, Gβ(3) may play a role in synaptic maintenance since in its absence, the number of invaginating rod bipolar dendrites is greatly reduced, a deficit that was not observed at 3 weeks, the end of the developmental period...
Autoantibodies in melanoma-associated retinopathy target TRPM1 cation channels of retinal ON bipolar cellsAnuradha Dhingra
Department of Neuroscience, University of Pennsylvania School of Medicine, Philadelphia, Pennsylvania 19104, USA
J Neurosci 31:3962-7. 2011..We conclude that the vision of at least some patients with MAR is compromised due to autoantibody-mediated inactivation of the TRPM1 channel...
mGluR6 transcripts in non-neuronal tissuesTamar Vardi
Department of Neuroscience, University of Pennsylvania, Philadelphia, Pennsylvania 19104, USA
J Histochem Cytochem 59:1076-86. 2011..Furthermore, calcium imaging with Fura-2 showed that application of L-AP4, an agonist for group III metabotropic glutamate receptors including mGluR6, elevated calcium in endothelial cells...
A retinal-specific regulator of G-protein signaling interacts with Galpha(o) and accelerates an expressed metabotropic glutamate receptor 6 cascadeAnuradha Dhingra
Department of Neuroscience, University of Pennsylvania, Philadelphia, Pennsylvania 19104 6058, USA
J Neurosci 24:5684-93. 2004..This would tend to match its kinetics to that of the OFF bipolar that arises directly from ligand-gated channels...
Kir2.4 surface expression and basal current are affected by heterotrimeric G-proteinsPyroja Sulaiman
Department of Neuroscience, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania 19104, USA
J Biol Chem 288:7420-9. 2013..Moreover, we show that in retinal ON bipolar cells lacking Gβ3, localization of Kir2.4 in the dendritic tips is reduced. We conclude that Gβγ targets Kir2.4 to the plasma membrane, and Gαo slows this down by binding Gβγ...
Neurochemical organization of the first visual synapseNoga Vardi
Department of Neuroscience, University of Pennsylvania, PA 19104, USA
Keio J Med 51:154-64. 2002..In this talk/review we describe the structures and the neurochemicals involved in transmitting the visual signal at this synaptic complex...
Probing neurochemical structure and function of retinal ON bipolar cells with a transgenic mouseAnuradha Dhingra
Department of Neuroscience, University of Pennsylvania School of Medicine, Philadelphia, Pennsylvania 19104 6058, USA
J Comp Neurol 510:484-96. 2008..The channels and modulators found in ON bipolar cells likely shape their light response. Additional uses of the Grm6-GFP mouse are also discussed...
Light response of retinal ON bipolar cells requires a specific splice variant of Galpha(o)Anuradha Dhingra
Department of Neuroscience, University of Pennsylvania, Philadelphia, Pennsylvania 19104, USA
J Neurosci 22:4878-84. 2002..Thus, the light response of the ON bipolar cell is probably carried by its strongly expressed splice variant, Galpha(o1)...
Cones respond to light in the absence of transducin β subunitSergei S Nikonov
Departments of Neuroscience and Ophthalmology, University of Pennsylvania, Philadelphia, PA 19104, USA
J Neurosci 33:5182-94. 2013..These results suggest that the main role of Gβ3 in cones is to establish optimal levels of transducin heteromer in the outer segment, thereby indirectly contributing to robust response properties...
