Ionotropic glutamate receptors of amacrine cells of the mouse retina.
The mammalian retina contains approximately 30 different morphological types of amacrine cells, receiving glutamatergic input from bipolar cells. In this study, we combined electrophysiological and pharmacological techniques in order to study the glutamate receptors expressed by different types of amacrine cells. Whole-cell currents were recorded from amacrine cells in vertical slices of the mo...
متن کاملDopaminergic and indoleamine-accumulating amacrine cells express GABA-like immunoreactivity in the cat retina.
Colocalization of indoleamine uptake and GABA-like immunoreactivity was studied in the cat retina. Consecutive, semithin sections were incubated in antisera to either 5-HT (5-hydroxytryptamine) or GABA. More than 90% of all 5-HT-accumulating amacrine cells expressed GABA-like antigens. With the same approach, the colocalization of 5-HT uptake and GABA-like immunoreactivity was studied in rabbit...
متن کاملInhibitory inputs tune the light response properties of dopaminergic amacrine cells in mouse retina.
Dopamine (DA) is a neuromodulator that in the retina adjusts the circuitry for visual processing in dim and bright light conditions. It is synthesized and released from retinal interneurons called dopaminergic amacrine cells (DACs), whose basic physiology is not yet been fully characterized. To investigate their cellular and input properties as well as light responses, DACs were targeted for wh...
متن کاملDopaminergic innervation of A II amacrine cells in mammalian retina.
Dopaminergic amacrine cells were stained in cat, rat, and rabbit retina using an antibody against tyrosine hydroxylase (TH). Following intraocular injection of DAPI (4,6,diamidino-2-phenylindole), subsequent retinal whole-mount preparations revealed that the dopaminergic fiber plexus formed rings around amacrine cell bodies. Intracellular injection of Lucifer yellow (LY) into A II amacrine cell...
متن کاملDopaminergic amacrine cells in rabbit retina: a confocal microscopic study
Objective: To demonstrate the relationship between dopamicergic amacrine (DA) cells and AII amacrine cells and to characterize DA cells of the rabbit retina. Methods: Retinal whole mounts were doubleor triple-labeled using antibodies against tyrosine hydroxylase (TH), calretinin (CR), and vesicular glutamate transporter 1 (VGLUT1) which selectively label DA cells, AII amacrine cells, and all bi...
