Summary of "Dorsal hypothalamic dopaminergic neurons play an inhibitory role in the hypothalamic-pituitary-adrenal axis via activation of D2R in mice."

The present study investigated the effects of dorsal hypothalamic dopamine (dh-DA) neurons on activation of hypothalamic-pituitary-adrenal (HPA) axis in adult male mice.

CD1 is involved in diet-induced hypothalamic inflammation in obesity.

Obesity-associated hypothalamic inflammation plays an important role in the development of defective neuronal control of whole body energy balance. Because dietary fats are the main triggers of hypoth...

Differential effects of hypo- and hyperthyroidism on remodeling of contacts between neurons expressing the Neuropeptide EI and Tyrosine Hydroxylase in hypothalamic areas of the male rat.

The Neuropeptide EI (NEI, glutamic acid- isoleucine amide) participates in neuroendocrine function. Previously we demonstrated that NEI concentration is regulated by thyroid hormones in discrete hypot...

Stress adaptation upregulates oxytocin within hypothalamo-vagal neurocircuits.

Stress plays a pivotal role in the development and/or exacerbation of functional gastrointestinal (GI) disorders. The paraventricular nucleus of the hypothalamus (PVN) contains neurons that are part o...

Centrally administered kisspeptin suppresses feeding via nesfatin-1 and oxytocin in male rats.

Kisspeptin (KP), known as a hypothalamic neuropeptide, plays a critical role in the regulation of not only reproduction but also food intake. The anorectic neuropeptides, nesfatin-1 and oxytocin (OXT)...

Initial evidence for hypothalamic gliosis in children with obesity by quantitative T2 MRI and implications for blood oxygen-level dependent response to glucose ingestion.

In adults, hypothalamic gliosis has been documented using quantitative T2 neuroimaging, whereas functional magnetic resonance imaging (fMRI) has shown a defective hypothalamic response to nutrients. N...

Medical and Biotech [MESH] Definitions

Cell surface receptors that bind the hypothalamic hormones regulating pituitary cell differentiation, proliferation, and hormone synthesis and release, including the pituitary-releasing and release-inhibiting hormones. The pituitary hormone-regulating hormones are also released by cells other than hypothalamic neurons, and their receptors also occur on non-pituitary cells, especially brain neurons, where their role is less well understood. Receptors for dopamine, which is a prolactin release-inhibiting hormone as well as a common neurotransmitter, are not included here.

A collection of NEURONS, tracts of NERVE FIBERS, endocrine tissue, and blood vessels in the HYPOTHALAMUS and the PITUITARY GLAND. This hypothalamo-hypophyseal portal circulation provides the mechanism for hypothalamic neuroendocrine (HYPOTHALAMIC HORMONES) regulation of pituitary function and the release of various PITUITARY HORMONES into the systemic circulation to maintain HOMEOSTASIS.

An orphan nuclear receptor that is found at high levels in BRAIN tissue. The protein is believed to play a role in development and maintenance of NEURONS, particularly dopaminergic neurons.

The part of the hypothalamus posterior to the middle region consisting of several nuclei including the medial mamillary nucleus, lateral mamillary nucleus, and posterior hypothalamic nucleus (posterior hypothalamic area). The posterior hypothalamic area is concerned with control of sympathetic responses and is sensitive to conditions of decreasing temperature and controls the mechanisms for the conservation and increased production of heat.

An aggregation of cells in the middle hypothalamus dorsal to the ventromedial nucleus and bordering the third ventricle.
