“…After enucleation of the eyes, a procedure which is known to stimulate pineal functional activity, a similar result has been described in mouse by Benson and Satterfietd (1975). After constant illumination which provokes an inhibition of pineal functional activity (for references, see Kappers, 1969), Upson et al (1976) observed in mouse a decrease in number of these vesicles. Until now, the exact nature of the compound(s) stored in them is unknown.…”

The different categories of cells described by many authors in the pineal gland of mammals have been critically considered. In some mammalian species, two different populations of pinealocytes have been observed. To each of these populations a specific secretory process can be attributed. One is characterized by the formation of granular vesicles originating from the Golgi apparatus, the other by the formation of material directly from the cisterns of the granular endoplasmic reticulum. Both of these secretory processes appear to be also present in the pineal of the mole, the hedgehog, and the rat, mammals in which generally only one population of pinealocytes has been described. The physiological consequences of these findings have been discussed.

“…However, a cholinergic parasympathetic innervation of the epiphysis cerebri, in contrast to the sympathetic supply, has been said not to be a regular feature in mammals (Kappers, 1960(Kappers, , 1965(Kappers, , 1969. Species reported to have parasympathetic innervation are the macaque monkey (Kenny, 1961) and the rabbit (Romijn, 1973a(Romijn, ,b, 1975a.…”

Ultrastructural localization of acetylcholinesterase in the guinea pig pineal gland

1990

The ultrastructural localization of acetylcholinesterase (AChE) activity in guinea pig pineal gland was studied using the copper-glycine procedure. A small number of pinealocytes and bundles of unmyelinated nerve fibers were labeled by the AChE reaction. The AChE-positive pinealocytes were located near blood vessels and distributed in small groups. The AChE reaction product was localized in the perinuclear cistern, in the cisternae of the endoplasmic reticulum (ER), and in the saccules of the Golgi apparatus. These findings suggest that the AChE-positive pinealocytes synthesize AChE. The AChE reaction product was also seen in the intercellular space between pinealocyte processes. Besides pinealocytes, AChE activity was localized on the axolemma of myelinated and unmyelinated nerve fibers and in the basement membrane surrounding unmyelinated nerve fibers. Pseudocholinesterase activity was confined to Schwann cells, which showed the reaction product in their perinuclear cistern, in the cisternae of the ER, and on the plasmalemma.

“…It has been established on both morphological and experimental grounds, that the mammalian pineal is predominantly innervated by sympathetic postganglionic nerve fibers derived from the superior cervical ganglia (Kappers, 1960(Kappers, , 1965(Kappers, , 1969. As has been confirmed biochemically, the functional activity of the pineal shows a diurnal rhythm in relation to daily light and dark cycles and is indirectly controlled by environmental lighting (see reviews by Wurtman et al, 1968;Wurtman and Anton-Tay, 1969;Axelrod, 1971).…”
