Study of the histomorphology of human pineal gland

National Journal of Clinical Anatomy, 2023
Introduction: Histologically, the pineal gland shows pinealocytes, glial cells, and sometimes calcific concretions. Age-related changes in these three components have been reported by various workers.

Spatio-temporal dynamics of nuclear CREB1: what does it mean? [PDF]

, 2022
In the mammalian pineal gland (PG), cyclic AMP responsive element-binding protein 1 (CREB1) participates in the nocturnal melatonin synthesis that rhythmically modulates physiology and behavior.

Epiphysis morphology under light and radiation exposure in experiment

Бюллетень сибирской медицины, 2003
Epiphysis is an organ of the control of biorhythms and adaptogenesis connected with photoperiodism. To evaluate photoradiomodificating effect and conarium plasticity using the methods of light and electron microscopy, there have been analyzed changes in ...

Cellular basis of pineal gland development: Emerging role of microglia as phenotype regulator [PDF]

, 2016
The adult pineal gland is composed of pinealocytes, astrocytes, microglia, and other interstitial cells that have been described in detail. However, factors that contribute to pineal development have not been fully elucidated, nor have pineal cell ...

Expression and cellular localization of the transcription factor NeuroD1 in the developing and adult rat pineal gland [PDF]

, 2015
Circadian rhythms govern many aspects of mammalian physiology. The daily pattern of melatonin synthesis and secretion is one of the classic examples of circadian oscillations.

The ISL LIM‐homeobox 2 transcription factor is negatively regulated by circadian adrenergic signaling to repress the expression of Aanat in pinealocytes of the rat pineal gland

Journal of Pineal Research, Volume 75, Issue 4, December 2023., 2023
Abstract Melatonin is synthesized in the pineal gland during nighttime in response to nocturnal increase in the activity of the enzyme aralkylamine N‐acetyltransferase (AANAT), the transcription of which is modulated by several homeodomain transcription factors. Recent work suggests that the homeodomain transcription factor ISL LIM homeobox 2 (ISL2) is
