The decrease in growth hormone (GH) response after repeated stimulation with GH-Releasing hormone is partly caused by an elevation of somatostatin tonus. [PDF]
Repeated injection of GHRH leads to a decrease in the GH response in normal subjects. Arginine (Arg) stimulates GH secretion by suppression of hypothalamic somatostatin.

Human Pancreas GH-Releasing Factor Analog Restores High-Amplitude GH Pulses in CNS Lesion-Induced GH Deficiency [PDF]
Lesions of the ventromedial-arcuate (VMH-ARC) region of the hypothalamus result in impaired growth accompanied by a marked suppression in spontaneous GH secretory bursts. We studied the effects of an analog of the recently characterized human pancreas GH-

Approach of Acromegaly during Pregnancy
Acromegaly-related sub/infertility, tidily related to suboptimal disease control (1/2 of cases), correlates with hyperprolactinemia (1/3 of patients), hypogonadotropic hypogonadism—mostly affecting the pituitary axis in hypopituitarism (10–80%), and ...

Preprotachykinin A (PPTA) is expressed by a distinct population of excitatory neurons in the mouse superficial spinal dorsal horn including cells that respond to noxious and pruritic stimuli [PDF]
The superficial dorsal horn, which is the main target for nociceptive and pruritoceptive primary afferents, contains a high density of excitatory interneurons.

Astrocytes Modulate Somatostatin Interneuron Signaling in the Visual Cortex
At glutamatergic synapses, astrocytes respond to the neurotransmitter glutamate with intracellular Ca2+ elevations and the release of gliotransmitters that modulate synaptic transmission.

Somatostatin and somatostatin receptors in Cushing's disease [PDF]
Cushing's disease is caused by an ACTH secreting pituitary adenoma. Surgery is the treatment of choice and cure rates between 60 and 90% are reported. For patients in which surgery fails, effective medical treatment options are needed. Somatostatin (SS) receptors (sst) are expressed on normal and tumoral corticotroph cells.

PET Imaging of Perceptual Learning-Induced Changes in the Aged Rodent Cholinergic System
The cholinergic system enhances attention and gates plasticity, making it a major regulator of adult learning. With aging, however, progressive degeneration of the cholinergic system impairs both the acquisition of new skills and functional recovery ...

Identifying functional populations among the interneurons in laminae I-III of the spinal dorsal horn [PDF]
The spinal dorsal horn receives input from primary afferent axons, which terminate in a modality-specific fashion in different laminae. The incoming somatosensory information is processed through complex synaptic circuits involving excitatory and ...
