Neonatal development of circadian rhythm in "synaptic" ribbon numbers in the rat pinealocyte.
American Journal of Anatomy, 1980Populations of "synaptic" ribbons (SR) in pinealocytes of the rat pineal gland at various ages from the neonatal period through early adulthood were analyzed morphometrically.

The effects of testosterone on the mice pinealocytes: a quantitative study
Tissue and Cell, 1999In order to determine the effects of testosterone upon the function of the pineal gland we quantitated, under the electron microscope, the number of dense-core vesicles, lysosomes, lipid droplets and the fractional volume of the pineal gland components in adult male mice.

Tubular lysosomes in rat and gerbil pinealocytes
Histochemistry, 1988Ultracytochemical demonstration of acid phosphatase (AcPase) in pinealocytes of rat and Mongolian gerbil (Meriones unguiculatus) has revealed an existence of tubular lysosomes (30-200 nm in diameter and more than 5 micron long) in their cytoplasm.

Localization of N- ethylmaleimide-sensitive fusion protein in pinealocytes
NeuroReport, 1995N-ethylmaleimide-sensitive fusion protein (NSF), a protein necessary for vesicular docking and/or fusion, was detected immunohistochemically in pinealocytes. NSF was distributed similarly to synaptophysin and vacuolar-type H(+)-ATPase (V-ATPase), marker proteins for synaptic-like microvesicles (MVs) abundantly present in pinealocytes.

Male adult (200-day-old) Chinese hamsters (Cricetulus griseus) raised from weaning under either LD 16:8 or LD 8:16 were used. The pineal gland of the Chinese hamster consists of superficial (major) and deep (minor) components and a continuous, or ...

Synaptic-like Microvesicles in Mammalian Pinealocytes
1999The recent deciphering of the protein composition of the synaptic vesicle membrane has led to the unexpected identification of a compartment of electron-lucent microvesicles in neuroendocrine cells which resemble neuronal synaptic vesicles in terms of molecular structure and function.

The ultrastructure of mammalian pinealocytes: A systematic investigation
Microscopy Research and Technique, 1992AbstractPinealocytes are not only the principal cellular components of the pineal gland, but they are also the principal synthetic machinery of this enigmatical gland with highly diverse and often questionable empyreal roles assigned to it. Ultrastructural descriptions of pinealocytes belonging to some 70 species of mammals (a mere 2% or less of the ...

The ultrstructure of neuronal‐pinealocytic interconnections in the monkey pineal
Microscopy Research and Technique, 1992AbstractRecent ultrastructural studies of neuronal‐pinealocytic interconnections in the monkey pineal are reviewed. The pinealocytes in the adult monkey show almost all of the cytological specializations known in subprimate mammals. Adjacent pinealocytes are functionally coupled through ribbon synapses on cell bodies and gap junctions on cell bodies ...

Direct photosensitivity of chick pinealocytes as demonstrated by visinin immunoreactivity [PDF]
Cell and Tissue Research, 1990 Visinin, a calcium-binding protein isolated from the soluble fraction of homogenized chick retinae, has been recognized immunocytochemically in the pinealocytes of various submammals. In the chick pineal organ, continuous environmental light induced an increase in population density of visinin-immunoreactive pinealocytes.

Mammalian pinealocytes: ultrastructural aspects and innervation.
Ciba Foundation symposium, 1985In the mammalian pineal gland it is notoriously difficult to relate structure to function. The pineal-specific cells, the pinealocytes, contain only inconspicuous numbers of secretory granules, and the variable amounts of smooth and rough endoplasmic reticulum also do not point to a particular function.
