Prolactin daily rhythm in suckling male rabbits

Journal of Circadian Rhythms, 2005
Background This study describes the 24-h changes in plasma prolactin levels, and dopamine (DA), serotonin (5HT), gamma-aminobutyric acid (GABA) and taurine concentration in median eminence and adenohypophysis of newborn male rabbits. Methods Animals were

Hypothalamic Rax+ tanycytes contribute to tissue repair and tumorigenesis upon oncogene activation in mice

Nature Communications, 2021
Tanycytes contribute to the regulation of multiple hypothalamic functions. Here the authors investigate the regenerative and tumorigenic potential of adult Rax+ tanycytes in the median eminence in the context of the stem cell niche in mice.

Distribution of GnRH and Kisspeptin Immunoreactivity in the Female Llama Hypothalamus

Frontiers in Veterinary Science, 2021
Llamas are induced non-reflex ovulators, which ovulate in response to the hormonal stimulus of the male protein beta-nerve growth factor (β-NGF) that is present in the seminal plasma; this response is dependent on the preovulatory gonadotrophin-releasing

IMMUNOHISTOCHEMICAL EXPRESSION OF MONOCARBOXYLATE TRANSPORTER 1&4 IN TANYCYTE–LIKE CELLS OF THE SULCUS MEDIANUS ORGANUM

The Iraqi Journal of Medical Sciences, 2019
Background: Circumventricular organs (CVOs) are specialized structures border the brain ventricles and lack the blood-brain barrier. These CVOs are lined by specialized ependymal cells (ECs) called tanycyte.

Development of Circumventricular Organs in the Mirror of Zebrafish Enhancer-Trap Transgenics

Frontiers in Neuroanatomy, 2017
The circumventricular organs (CVOs) are small structures lining the cavities of brain ventricular system. They are associated with the semitransparent regions of the blood-brain barrier (BBB).

Bitter taste cells in the ventricular walls of the murine brain regulate glucose homeostasis

Nature Communications, 2023
The median eminence (ME) at the base of the brain controls body homeostasis. Here, the authors describe a functional tanycyte subpopulation at the ME which tastes the surrounding milieu, responds to metabolic signals and regulates glucose homeostasis.

Opposite effects of a high-fat diet and calorie restriction on ciliary neurotrophic factor signalling in the mouse hypothalamus

Frontiers in Neuroscience, 2013
In the mouse hypothalamus, ciliary neurotrophic factor (CNTF) is mainly expressed by ependymal cells and tanycytes of the ependymal layer covering the third ventricle.

Ultrastructure of Hypothalamic Neurons and of the Median Eminence [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1974
SUMMARYOur light, and electron microscopic (EM) findings within the hypothalamic supraoptic (SO) and paraventricular (PV) nuclei of the normal female rabbit are in agreement with those reported earlier by other investigators for the same nuclei of the dog and rat.

Effect of maternal deprivation on the gonadotrophin-releasing hormone (GnRH) and GnRH-associated peptide neurobiology in lambs during the transition from infancy to prepuberty.

Folia Histochemica et Cytobiologica, 2010
Using morphological criteria we describe the effect of maternal deprivation on the gonadotrophin-releasing hormone (GnRH) and GnRH-associated peptide (GAP) of the GnRH prohormone (proGnRH) in the preoptic area (POA)-hypothalamus during the weaning period.
