Morphologic development of neonatal rat pinealocytes in monolayer culture

Cell and Tissue Research, 1981
The morphological development of pinealocytes maintained in monolayer culture, without the neural and humoral effects present in the developing rat has been studied and compared with the development that occurs in vivo. Pinealocytes in 5 day cultures contained organelles that were similar to those present in the pineals of intact 5 day old rats ...

Cytochemistry of CSF-contacting neurons and pinealocytes.

Progress in brain research, 1992
Gamma aminobutyric acid (GABA)-immunoreactive neurons of the paraventricular organ of the bony fish Coregonus albus send dendrites into the third ventricle. Their axons run to the synaptic zone of the infundibular lobe. The dendrites may take up some chemical information from the third ventricle, while the axons communicate it to the neuropil of the ...

Cyclic AMP-induced release of [14C]taurine from pinealocytes

Biochemical and Biophysical Research Communications, 1979
Abstract Pinealocytes were prelabelled with [ 14 C]taurine. Twenty-four hours later they were treated with derivatives of cyclic AMP. It was found that dibutyryl cyclic AMP and ϱ-chloro-phenyl-thio cyclic AMP treatment caused a large increase in the release of [ 14 C]taurine.

Comparative ultrastructure of cerebrospinal fluid-contacting neurons and pinealocytes

Cell and Tissue Research, 1975
The pinealocytes of fishes, amphibians, reptiles, birds and mammals have been compared with cerebrospinal fluid (CSF) contacting neurons. We found that the intraventricular dendrite terminal of the latter resembles the pinealocytic inner segment and that the atypical cilium (9x2+0 tubules) of the CSF contacting neurons is analogous with the outer ...

Cytospectrofluorometric characterization of OPT-induced fluorescence in rat pinealocytes

Histochemistry, 1974
o-Phthaldialdehyde (OPT) has been employed for the fluorescence histochemical demonstration of histamine. OPT-induced fluorescence with properties different from those of the histamine fluorophore was examined in cells of rat pineal, retina and endocrine pancreas.

β-Adrenergic regulation of cyclic GMP in rat pinealocytes

Biochemical and Biophysical Research Communications, 1990
Stimulation of rat pinealocyte cyclic GMP by beta-adrenergic agonists (in the presence of prazosin to block alpha 1-adrenoceptors) showed an identical potency order (isoproterenol greater than epinephrine = norepinephrine much greater than salbutamol greater than terbutaline) to the stimulation of pinealocyte cyclic AMP.

Mammalian pinealocytes: ultrastructural aspects and innervation.

Ciba Foundation symposium, 1986
In 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.

Transformation of centrioles in pinealocytes of adult guinea pigs

Journal of Neurocytology, 1972
Pinealocytes from adult guinea pigs contain conventional centrioles and microtubular sheaves composed of varying numbers of doublet and/or triplet tubules of indefinite length embedded in a dense matrix, which are assumed to be formed by elongation and dissociation of the centriolar wall.
