Example sentences for: photoreceptor

How can you use “photoreceptor” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In contrast to the inner retinal layers, the photoreceptor layer typically appeared normal.

  • RPE cells express all three forms of PPARs but PPARβ is the dominant isoform [ 24 ] . There is a 10-fold induction of PPARγ mRNA that reaches a peak at 4-hour after phagocytosis of photoreceptor outer segments.

  • It induces neuronal differentiation in retinoblastoma cells, protects retina neurons (including photoreceptors) from death by apoptosis and other insults, and has a morphogenetic effect on photoreceptor cells [ 3 4 5 6 ] . It also has neurotrophic effects on neurons from the cerebellum, hippocampus and spinal cord [ 7 8 9 10 11 12 ] . In the intact retina, this factor is identified as a secreted protein associated by ionic interactions with the interphotoreceptor matrix [ 13 14 ] , where GAGs are the major polyanionic components.

  • Previous studies of cryptochrome's chronobiological role in Drosophila emphasized that CRY may function as a deep brain photoreceptor involved in mediating resetting of the clock by light [ 26 ] . Support for this hypothesis came from the observation that locomotor-activity rhythms in cry b flies are unaffected in constant darkness and also maintain rhythmicity under constant light, a condition that causes behavioral arrhythmicity in the wild type [ 33 ] . While antennal rhythms of gene expression and of odor sensitivity in DD are significantly attenuated in cry b tissues ( [ 23 ] , unlike locomotor rhythmicity [ 21 ] ), it remained possible that such effects are due to an altered role of light on the developing clock.

  • Any single photoreceptor might respond equally to a medium intensity light in the wavelength range of its peak sensitivity, and to a strong intensity light at the periphery of its sensitive range—hence it cannot disentangle wavelength from intensity [5].
