Oligodendrocytes of the adult median eminence
… studies highlighting that OPCs in the adult median eminence (ME) are highly proliferative and rapidly differentiate in response to nutritional signals. As such, these data raise questions about new OL and myelin generation in the ME at baseline, the fate of pre-existing OLs here, and the …

Oligodendrocytes of the adult hypothalamic median eminence
The median eminence (ME) of the hypothalamus is a dynamic structure able to rapidly respond to nutrient availability. Both immature oligodendrocyte precursor cells (OPCs) and mature myelinating oligodendrocytes (MOLs) are found in this region in adults. While proliferation of ME OPCs has been shown …

The oligodendrocyte lineage of the median eminence in the adaptation to diet-induced obesity
The median eminence (ME) is a structure with an essential role in the hypothalamic regulation of energy balance, forming an interface between the central nervous system and the periphery which allows blood-borne endocrine and nutritional signals to interact with appetite-regulatory neurons. Within …

The Role of GABA in Reproductive Neuroendocrine Systems
… effect of stimulation of GABA receptors in the median eminence on LHRH and 5-HIAA release.</p> <p>The intact rat model released greater amounts of LHRH than the ovariectomized rat model. The proestrus hormonal state had more LHRH released than the estrus state; however, the activity of the …

Regulation of Luteinizing Hormone and Catecholamine Release
… were utilized to determine plasma LH and median eminence LHRH, and hypothalamic catecholamine concentrations were measured by radioenzymatic assay.</p> <p>The first two studies tested whether epinephrine (EPI) synthesis inhibition blocks the accumulation of median eminence LHRH that …

Localization of Luteinizing Hormone-Releasing Hormone (LHRH) in the Hypothalamus of Fetal Bovine
… nucleus and axons were observed in the median eminence and ventral to the third ventricle.

Neuroendocrine regulation of broodiness in the domestic hen
… those VIP and GnRJ-I-I fibres was seen in the median eminence. GnIH was localized in cells in the paraventricular nucleus (PVN) in incubating and laying hens did not contain PR-ir and had terminals in the median eminence. The density of GnIH neurones did not differ between laying and incubating …

Cloning and charaterisation of the Thyrotrophin-releasing hormone receptor and Gonadotrophin-relasing hormone receptor from chicken pituitary gland
… TRH and GnRH are released and stored in the median eminence, and both hormones are transported into the pituitary gland via the hypophysial portal circulation. TRH and GnRH exert their physiological functions by binding to their specific receptors (TRH receptor and GnRH receptor, …

Characterization of Tyrosine Hydroxylase-Positive Neurons Projections from the Paraventricular Nucleus of Hypothalamus to Hindbrain Autonomic Regulatory Centers
… there was also dense projects into the and median eminence (ME) that regulates neural hormones release. In sum, the THPVN neuron projects anatomically to the autonomic and neurosecretory regions of brain and may modulate the cardiometabolic activity through these projections.

Characterizing cerebellin-short, a novel circadian peptide, in the rat suprachiasmatic nucleus
… (PVN), the supraoptic nucleus (SON) and the median eminence. No Cbln1 or process intermediate were observed in GFAP-positive astrocytes. Crude synaptosome fractionations of the SCN revealed that the processing intermediate, but not Cbln1, is enriched at the synapse. Exogenous application of …

Evidence for effects of phoenixin on neurons of the paraventricular nucleus
… Through projections to the pituitary gland, median eminence and hindbrain, the PVN plays a role in stress response and other autonomic functions. Recent findings have indicated that both phoenixin (PNX), a peptide involved in such responses, and its receptor, GPR173, are expressed throughout …

Characterizing the Hypothalamic Functions of Irx3 and Irx5 in Energy Balance Regulation
… Irx5 are expressed in the arcuate nucleus and median eminence (ARC-ME), a hypothalamic site known to control energy homeostasis via distinct cell types, yet the identities of Irx3- and Irx5-expressing hypothalamic cells and their roles in regulating energy balance remain poorly characterized. …

A Study of the in Vivo Release of Luteinizing Hormone-Releasing Hormone as Estimated With the Push-Pull Perfusion Technique
… tip approximately 0.5 mm from the rostral median eminence. A PPP system was also used to carry out the first examination of LHRH release during stages of the estrous cycle and following Ovx. It was found that (i) a biphasic LHRH surge occurs on proestrus which may prime and then stimulate …

Gold Nanoparticles as a Delivery System of Oligonucleotides into the Brain
… parenchyma of the cortex, striatum, hippocampus, median eminence and choroid plexus. However, a biodistribution study of the gold, by ICP-mass spectrometry showed that the great majority of the injected nanoparticles were present in the kidney. Finally, a cargo molecule of DNA oligonucleotide was …

The gonadotropin-releasing hormone (GnRH) system: a comparison between breeding and non-breeding naked mole rats (Heterocephalus glaber)
… females. GnRH neurons were found in the median eminence of the hypothalamus and in the anterior pituitary of both queens and subordinates, however in the brain of queen (n = 7) naked mole rats, there is a significantly larger area of immunoreactivity in comparison to the subordinate (n = …
