PMID: 33387934
The skate retina provides a native all-rod retina suited for investigating a single type of photoreceptor regarding its properties and signaling to second order cells. Using the aspartate-induced isolated A-wave...

PMID: 25324679
This review covers a broad range of topics related to the actions of zinc on the cells of the vertebrate retina. Much of this review relies on studies in which...

J Neurochem
. 2013 Nov;
129(2):249-55.
PMID: 24286124
Our recent studies have shown that endogenous zinc, co-released with glutamate from the synaptic terminals of vertebrate retinal photoreceptors, provides a feedback mechanism that reduces calcium entry and the concomitant...

Exp Eye Res
. 2013 Apr;
112:37-44.
PMID: 23619034
There is abundant experimental evidence that zinc ions (Zn(2+)) are present in the synaptic vesicles of vertebrate photoreceptors, and that they are co-released with glutamate. Here we show that increasing...

Chappell R, Anastassov I, Lugo P, Ripps H
Exp Eye Res
. 2008 Jul;
87(4):394-7.
PMID: 18638476
There is mounting evidence that zinc release from glutamatergic nerve terminals serves as a neuromodulator at synaptic sites within the retina and CNS. However, it has not been possible to...

Zebrafish
. 2008 Feb;
2(3):189-96.
PMID: 18248193
Photographic images of the optokinetic response (OKR) of larval zebrafish permitted the calculation of the amplitude and velocity of the response to gratings of various spatial frequencies rotating at different...

Redenti S, Ripps H, Chappell R
Exp Eye Res
. 2007 Sep;
85(4):580-4.
PMID: 17825289
The presence of reactive zinc (Zn2+) within photoreceptor terminals, and evidence that exogenous zinc affects the electrophysiological activity of the distal retina, led to the suggestion that its co-release with...
