Glia-pinealocyte network: the paracrine modulation of melatonin synthesis by tumor necrosis factor (TNF). [PDF]

open access: goldPLoS ONE, 2012
The pineal gland, a circumventricular organ, plays an integrative role in defense responses. The injury-induced suppression of the pineal gland hormone, melatonin, which is triggered by darkness, allows the mounting of innate immune responses.

Single-cell RNA sequencing of the mammalian pineal gland identifies two pinealocyte subtypes and cell type-specific daily patterns of gene expression. [PDF]

open access: yesPLoS ONE, 2018
The vertebrate pineal gland is dedicated to the production of the hormone melatonin, which increases at night to influence circadian and seasonal rhythms. This increase is associated with dramatic changes in the pineal transcriptome.

MICROCYLINDERS WITHIN MITOCHONDRIAL CRISTAE IN THE RAT PINEALOCYTE [PDF]

open access: bronzeThe Journal of Cell Biology, 1965
A minute cylindrical structure with a dense core, designated as "microcylinder," has been observed within enlarged spaces of mitochondrial cristae in pinealocytes of some adult rats (osmium tetroxide fixed, methacrylate embedded).

The pinealocyte--a paraneuron? A review.

open access: bronzeArchivum histologicum japonicum, 1977
The pineal complex develops from a tubular evagination of the diencephalic roof. In amphibians a proliferation zone is the source of the pinealocytes and of the cells of the subcommissural organ.

Long-Term Effects of Perinatal Exposure to a Glyphosate-Based Herbicide on Melatonin Levels and Oxidative Brain Damage in Adult Male Rats [PDF]

open access: yesAntioxidants, 2023
Concerns have been raised regarding the potential adverse health effects of the ubiquitous herbicide glyphosate. Here, we investigated long-term effects of developmental exposure to a glyphosate-based herbicide (GBH) by analyzing serum melatonin levels ...

Profiling Temporal Changes of the Pineal Transcriptomes at Single Cell Level Upon Neonatal HIBD [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2022
Neonatal hypoxic-ischemic brain damage (HIBD) often results in various neurological deficits. Among them, a common, yet often neglected, symptom is circadian rhythm disorders. Previous studies revealed that the occurrence of cysts in the pineal gland, an

Cytodifferentiation of pinealocytes (I and II) and astrocyte types of mature male sheep epiphysis cerebri with special emphasis on the presence of neuronal and pigmented like cells [PDF]

open access: yesOpen Veterinary Journal, 2023
Background: The epiphysis cerebri (pineal gland) is a small-sized, photo neuroendocrine organ in the brain of most vertebrates. Their effect is through secretion of melatonin, a serotonin-derived hormone which is stimulated by darkness and inhibited by ...

Morphology of the Human Pineal Gland Studied by Freeze-Fracturing in Scanning Electron Microscopy [PDF]

open access: yesLife
The human pineal gland is the largest producer of the hormone melatonin. Pineal acervuli (brain sand), calcified concretions in the pineal gland, have long been studied because of their association with ageing, melatonin production, and neurological ...

A PECULIAR CONFIGURATION OF AGRANULAR RETICULUM (CANALICULATE LAMELLAR BODY) IN THE RAT PINEALOCYTE [PDF]

open access: bronzeJournal of Cell Biology, 1967
A cytoplasmic structure exhibiting a peculiar configuration of agranular reticulum has been found in the rat pinealocyte, and has been designated a canaliculate lamellar body.

Sex-Specific Methylomic and Transcriptomic Responses of the Avian Pineal Gland to Unpredictable Illumination Patterns. [PDF]

open access: yesJ Pineal Res
ABSTRACT In the production environment of chickens, exposure to unpredictable light patterns is a common painless stressor, widely used to influence growth rate and egg production efficiency. The pineal gland, a key regulator of circadian rhythms through melatonin secretion, responds to environmental light cues, and its function is modulated by ...
