AbstractPhotoreceptor degenerative diseases (e.g., retinitis pigmentosa or age‐related macular degeneration) are currently one of the leading causes of irreversible blindness in the world. Although their pathophysiological mechanisms may vary, they all share some features such as initial photoreceptor loss associated with glial activation and ...

Retinal bipolar cells: Temporal filtering of signals from cone photoreceptors
Visual Neuroscience, 2007The temporal dynamics of the response of neurons in the outer retina were investigated by intracellular recording from cones, bipolar, and horizontal cells in the intact, light-adapted retina of the tiger salamander (Ambystoma tigrinum), with special emphasis on comparing the two major classes of bipolars cells, the ON depolarizing bipolars (Bd) and ...

AbstractDegeneration and apoptotic death of the photoreceptor cell‐layer of retina are a major cause of irreversible blindness in the development era. The stem cell replacement therapy is one of the strategies for the retinal repairing. In addition, exogenous signals critically contribute to the direction of lineage decisions that causes the fate ...

Restoration of Cone Photoreceptor Function in Retinitis Pigmentosa (RP): Retinal Cell-Based Therapy
2019The major cause of hereditary blindness in North America is retinitis pigmentosa (RP), which is a group of inherited retinal diseases characterized by the onset of night blindness, early loss of peripheral vision, and late loss of central vision.

The purpose of the study was to investigate the characteristics of the parafoveal cone density changes in patients with retinitis pigmentosa (RP) using adaptive optics scanning laser ophthalmoscopy (AO-SLO).A total of 14 eyes of RP patients and 10 eyes of control subjects were examined.

Cones are the color-detecting photoreceptors of the vertebrate eye. Cones are specialized into subtypes whose functions are determined by the expression of color-sensitive opsin proteins. Organisms differ greatly in the number and patterning of cone subtypes.

The avian pineal is a photoreceptive organ and is believed to function as a circadian clock. Avian pineal cells are secretory rudimentary photoreceptors, and previous studies have demonstrated that there are two types of photoreceptors in developing quail pineals, one of which is rhodopsin-like immunoreactive and the other iodopsin-like immunoreactive.
