Synaptic Depression and the Kinetics of Exocytosis in Retinal Bipolar Cells [PDF]
The capacitance technique was used to investigate exocytosis at the ribbon synapse of depolarizing bipolar cells from the goldfish retina. When the Ca2+current was activated strongly, the rapidly releasable pool of vesicles (RRP) was released with a single rate-constant of ∼300–500 sec−1.

Hierarchical retinal computations rely on hybrid chemical-electrical signaling
Summary: Bipolar cells (BCs) are integral to the retinal circuits that extract diverse features from the visual environment. They bridge photoreceptors to ganglion cells, the source of retinal output.

Imaging Exocytosis in Retinal Bipolar Cells with TIRF Microscopy [PDF]
Total internal reflectance fluorescence (TIRF) microscopy is a technique that allows the study of events happening at the cell membrane, by selective imaging of fluorescent molecules that are closest to a high refractive index substance such as glass. In this article, we apply this technique to image exocytosis of synaptic vesicles in retinal bipolar ...

Retinal ischemia is a common pathomechanism in various eye diseases. Recently, evidence accumulated suggesting that the extracellular matrix (ECM) glycoprotein tenascin-C (Tnc) plays a key role in ischemic degeneration.

General features of the retinal connectome determine the computation of motion anticipation [PDF]
Motion anticipation allows the visual system to compensate for the slow speed of phototransduction so that a moving object can be accurately located.

Photoreceptor degeneration differentially impacts glutamatergic signaling in downstream On and Off bipolar cells. In rodent models, photoreceptor degeneration leads to loss of glutamatergic signaling in On bipolar cells, whereas Off bipolar cells appear ...

Dendritic and axonal targeting patterns of a genetically-specified class of retinal ganglion cells that participate in image-forming circuits. [PDF]
BackgroundThere are numerous functional types of retinal ganglion cells (RGCs), each participating in circuits that encode a specific aspect of the visual scene.

TULP4, a novel E3 ligase gene, participates in neuronal migration as a candidate in schizophrenia
Mutations identified from four SCZ pedigrees resulted in decreased TULP4 expression. Tulp4 knockdown caused delayed neuron migration in embryonic mice, and impaired cognition and prepulse inhibition in adult mice. These phenotypes may be related to TULP4 through its involvement in the formation of a novel E3 ubiquitin ligases.

Attenuation of Oxygen-Induced Neovascularization and Inflammation by Neutralizing VEGFA and/or ANG-2 With an Antibody. [PDF]
The effects of intraocular administration of neutralizing antibodies against VEGFA, ANG‐2, or bispecific to these two factors on pathological findings were examined in the oxygen‐induced retinopathy (OIR) mouse model. The antibody to VEGFA or ANG‐2 attenuated oxygen‐induced neovascularization and inflammation, and the bispecific antibody more ...

Allosteric modulation of retinal GABA receptors by ascorbic acid [PDF]
Ionotropic GABA receptors (GABAA and GABAC) belong to the Cys-loop receptor family of ligand-gated ion channels. GABAC receptors are highly expressed in the retina, mainly localized at the axon terminals of bipolar cells.
