Uptake of horseradish peroxidase by frog photoreceptor synapses in the dark and the light

Nature, 1974
INDIRECT evidence suggests that vertebrate photoreceptors decrease their release of a depolarising transmitter substance in response to the absorption of light. Vertebrate photoreceptors1–3 and most horizontal cells2,4 hyperpolarise in response to light and show an increased membrane resistance.

Accumulation of autophagosomes in aging human photoreceptor cell synapses

Experimental Eye Research
Autophagy is common in the aging retinal pigment epithelium (RPE). A dysfunctional autophagy in aged RPE is implicated in the pathogenesis of age-related macular degeneration. Aging human retina accompanies degenerative changes in photoreceptor mitochondria.

Adaptive processes at photoreceptor ribbon synapses

2012
Ribbon synapses are highly specialized chemical synapses found in sensory neurons like the hair cells in the inner ear and retinal photoreceptors. They are characterized by an electron-dense structure, the synaptic ribbon, which is anchored to the active zone.

Molecular Components of Vesicle Cycling at the Rod Photoreceptor Ribbon Synapse

Rod photoreceptors are light-sensitive neurons of the retina that support vision in dim light. A rod cell consists of an outer segment for phototransduction, an inner segment and soma for energy production and protein synthesis, and a synaptic terminal for vesicle release onto second-order neurons-bipolar and horizontal cells.

Transmission at the Mammalian Cone Photoreceptor Basal Synapse

2003
Cone photoreceptor synaptic terminals have both an unusual structure and an unusual function. The unusual structure is called the basal contact. At these contacts, the membranes of a cone and a postsynaptic cell, usually an Off bipolar cell, come into close apposition, but the stigmata of synaptic transmission, presynaptic clusters of vesicles and ...
