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.

Hypothalamic Tanycytes: Gatekeepers to Metabolic Control [PDF]
Cell Metabolism, 2014 How circulating signals of hunger and satiety enter the brain to reach neurons that govern energy balance has long remained a matter of controversy and speculation. Balland et al. (2014) now elucidate molecular mechanisms by which a highly specialized hypothalamic glial cell regulates transport of leptin across the blood-brain barrier.

Tanycytes and the Control of Thyrotropin-Releasing Hormone Flux Into Portal Capillaries
Frontiers in Endocrinology, 2019 Central and peripheral mechanisms that modulate energy intake, partition and expenditure determine energy homeostasis. Thyroid hormones (TH) regulate energy expenditure through the control of basal metabolic rate and thermogenesis; they also modulate ...

Extramedullary tanycytic ependymoma of the lumbar spinal cord [PDF]
Yeungnam University Journal of Medicine, 2020 Tanycytic ependymoma is a rare variant of ependymoma that commonly affects the cervical and thoracic spinal cord. It usually arises as intramedullary lesions, and extramedullary cases are extremely rare. We report a case of a 44-year-old woman who was diagnosed with tanycytic ependymoma in her lumbar spine at level 2-3.

Maternal Photoperiodic Programming: Melatonin and Seasonal Synchronization Before Birth
Frontiers in Endocrinology, 2020 This mini-review considers the phenomenon of maternal photoperiodic programming (MPP). In order to match neonatal development to environmental conditions at the time of birth, mammals use melatonin produced by the maternal pineal gland as a ...

iScience, 2020 Summary: Based on the type-I cannabinoid receptor (CB1) content of hypophysiotropic axons and the involvement of tanycytes in the regulation of the hypothalamic-pituitary-thyroid (HPT) axis, we hypothesized that endocannabinoids are involved in the ...

Tanycytic Ependymoma: A Challenging Histological Diagnosis [PDF]
Case Reports in Neurological Medicine, 2013 Tanycytic ependymoma is a rare form of ependymoma that usually arises in the intramedullary spine. It has a unique histology emphasized by the inconspicuous ependymal pattern of cells and close resemblance to schwannoma and astrocytoma. The authors report a 50-year-old man with a cervical tanycytic ependymoma that was initially thought to be a ...
