The somatostatin neurons in the periventricular nucleus mediate negative feedback effects of growth hormone on its own release; the somatostatin neurons respond to high circulating concentrations of growth hormone and somatomedins by increasing the release of somatostatin, so reducing the rate of secretion of growth hormone.

Structure of somatostatin. Somatostatin receptor antagonists (or somatostatin inhibitors) are a class of chemical compounds that work by imitating the structure of the neuropeptide somatostatin, which is an endogenous hormone found in the human body. The somatostatin receptors are G protein-coupled receptors.
Centrally projecting neurons that make somatostatin; the neurosecretory somatostatin neurons that regulate growth hormone secretion are a different population, located in the periventricular nucleus. Feeding regulatory neurons also activate oxytocin-containing neurons of the periventricular nucleus (PVN), which projects to nucleus of tractus ...
The somatostatin family is a protein family with somatostatin as titular member, a hormone which inhibits the release of the pituitary somatotropin (growth hormone) and inhibits the release of glucagon and insulin from the pancreas of fasted animals. Cortistatin is a cortical neuropeptide with neuronal depressant and sleep-modulating properties ...
The periventricular nucleus is a thin sheet of small neurons located in the wall of the third ventricle, a composite structure of the hypothalamus. It functions in analgesia. It is located in the rostral, intermediate, and caudal regions of the hypothalamus. The rostral region aids in the production of both somatostatin and thyroid releasing ...
Somatostatin is encoded by a CRE and is very susceptible to gene promoter region activation by transcription factor CREB. [1] There are five known somatostatin receptors: [2] SST 1 ; SST 2 ; SST 3 ; SST 4 ; SST 5 ; All are G protein-coupled seven transmembrane receptors.
Somatostatin receptor antagonists (or somatostatin inhibitors) are a class of chemical compounds that work by imitating the structure of the neuropeptide somatostatin. The somatostatin receptors are G protein-coupled receptors. Somatostatin receptor subtypes in humans are sstr1, 2A, 2 B, 3, 4 and 5. [1]
Since somatostatin-expressing neurons typically block dendritic inputs to the postsynaptic neuron, thus inhibiting signals traveling through associated structures, it is believed that the larger bed nucleus of the stria terminalis found in men (including transgender men) reduce the startle response in men and may be responsible for the higher ...
