Sympathetic Innervation of the Mammalian Pineal Gland: Its Involvement in Ontogeny and Physiology, and in Pineal Dysfunction [PDF]

open access: yes, 2023
In mammals, the melatonin-producing pineal gland (PG) receives sympathetic innervation from the superior cervical ganglia (SCG). This chapter describes the role of this innervation on the PG’s ontogeny and rhythmic function, along with consequences to ...

Roles of connexins and pannexins in (neuro)endocrine physiology. [PDF]

open access: yes, 2015
International audienceTo ensure appropriate secretion in response to organismal demand, (neuro)endocrine tissues liberate massive quantities of hormone, which act to coordinate and synchronize biological signals in distant secretory and non-secretory ...

Waning light, waxing pain: The lunar cycle's association with migraine headache occurrence

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Plain Language Summary While migraine headaches can be hard to predict, some patients believe headaches are connected to the moon‘s phases. Our research showed that migraine attacks were 34% more likely to occur during the new moon than during the full moon.

The Effects of Food on Circadian Rhythm: A Comprehensive Review

open access: yeseFood, Volume 6, Issue 5, October 2025.
(a) Light signals are received by the retina and transmitted to the suprachiasmatic nucleus (SCN), the master circadian clock, which synchronizes peripheral clocks in metabolic tissues via neural and humoral pathways (e.g., cortisol). (b) The molecular clock is governed by a transcriptional‐translational feedback loop.

Synaptic-like microvesicles, synaptic vesicle counterparts in endocrine cells, are involved in a novel regulatory mechanism for the synthesis and secretion of hormones [PDF]

open access: yes, 2001
Microvesicles in endocrine cells are the morphological and functional equivalent of neuronal synaptic vesicles. Microvesicles accumulate various neurotransmitters through a transmitter-specific vesicular transporter energized by vacuolar H+-ATPase.

The Chronological Trigger: The Orchestra Between Homeobox Genes and the Circadian Clock During Development

open access: yesBiology of the Cell, Volume 117, Issue 7, July 2025.
Homeobox genes associated with the circadian rhythm and the development of specific tissues, playing crucial roles in regulating cellular differentiation and the formation of structures during embryonic development. ABSTRACT As master regulators of embryonic development, regulating homeobox genes is fundamental for developmental biology.

Characterization of lymphocyte subsets over a 24-hour period in Pineal-Associated Lymphoid Tissue (PALT) in the chicken [PDF]

open access: yes, 2006
BACKGROUND: Homeostatic trafficking of lymphocytes in the brain has important relevance to the understanding of CNS disease processes. The pineal gland of the chicken contains large accumulations of lymphocytes that suggest an important role related to ...
