41. In RP photoreceptor cell death is believed to occur by programmed cell death or apoptosis. 42. As with digital photocopiers and multifunction printers ( MFPs ), laser printers employ a photoreceptor . 43. In medical terminology, " photopigment " commonly refers to the photoreceptor proteins of the retina. 44. :See : Interference and Photoreceptor recovery rate opps . . . not yet an article. 45. Besides photoreceptor proteins, eyespots contain a large number of structural, metabolic and signaling proteins. 46. SFRP1 and SFRP5 may be involved in determining the polarity of photoreceptor cells in the retina. 47. Thus, each element of LRGB targets one type of photoreceptor cell in the human eye. 48. When shi was expressed in photoreceptor cell, fly larva showed temporary temperature-dependent blindness. 49. A third class of mammalian photoreceptor cell was discovered during the 1990s : the photosensitive ganglion cells. 50. It is still not known why the absence of cGMP-gated cation channels causes photoreceptor degradation.
