Parvalbumin-immunoreactive amacrine cells of macaque retina.
A number of authors have observed amacrine cells containing high levels of immunoreactive parvalbumin in primate retinas. The experiments described here were designed to identify these cells morphologically, to determine their neurotransmitter, to record their light responses, and to describe the other cells that they contact. Macaque retinas were fixed in paraformaldehyde and labeled with anti...
متن کاملThe organization of melanopsin-immunoreactive cells in microbat retina
Intrinsically photosensitive retinal ganglion cells (ipRGCs) respond to light and play roles in non-image forming vision, such as circadian rhythms, pupil responses, and sleep regulation, or image forming vision, such as processing visual information and directing eye movements in response to visual clues. The purpose of the present study was to identify the distribution, types, and proportion ...
متن کاملCharacterization of secretagogin-immunoreactive amacrine cells in marmoset retina.
The retina contains at least 30 different types of amacrine cells but not many are well characterized. In the present study the calcium-binding protein secretagogin was localized in a population of regular and displaced amacrine cells in the retina of the common marmoset Callithrix jacchus. Irrespective of their soma location, the dendrites of secretagogin amacrine cells occupy strata 2, 3, and...
متن کاملCells immunoreactive for neuropeptide in human thymomas.
The presence of opioid peptides, bombesin, and substance P was investigated by immunohistochemistry in tissue sections from six human thymomas. The number of immunoreactive cells seemed to vary from one case to another. Ultrastructural investigation, showing the presence of desmosomes in labelled cells, allowed these cells to be classified as epithelial lineage cells. The occurrence of cells co...
متن کاملLocalization of immunoreactive cholecystokinin precursor to amacrine cells and bipolar cells of the macaque monkey retina.
We used antisera that recognized precursors of the neuropeptide cholecystokinin extended at the carboxyl terminus in an immunocytochemical study of the macaque retina. A subpopulation of bipolar cells with long, obliquely oriented dendrites was labeled. Their axons terminated exclusively in the fifth stratum of the inner plexiform layer, where they contacted processes of amacrine and ganglion c...
