Astrocytes are neural cells of ectodermal, neuroepithelial origin that provide for homeostasis
and defense of the central nervous system (CNS). Astrocytes are highly heterogeneous in …

In the brain, astrocytes are associated intimately with neurons and surround synapses. Due
to their close proximity to synaptic clefts, astrocytes are in a prime location for receiving …

Astrocytes, which constitute the most abundant cell type in mammalian brain, are extensively
coupled to one another through gap junctions composed mainly of connexin43. In regions …

Receptors for transmitters, as varied as those expressed by neurons, have been described
on primary astrocyte cultures prepared from new-born rats and mice. A variety of functional …

The tetradecapeptide somatotropin-release inhibiting factor somatostatin-14 regulates the
release of peptide hormones and also functions as neurotransmitter. The octacosapeptide …

The main somatostatin‐degrading proteases were purified from rat and pig brain
homogenates and characterized as thiol‐and metal‐dependent endoproteases. Two types …

Several neuropeptides, including neurotensin, somatostatin, bradykinin, angiotensin II,
substance P, and luteinizing hormone‐releasing hormone but not vasopressin and oxytocin …

The recent availability of isotope-labelled somatostatin analogues has allowed one to detect
somatostatin receptors in normal tissue as well as in endocrine or non-endocrine cranial …

Astroglial cells derived from the mammalian central nervous system contain a wide variety of
peptide receptors, including specific sites for angiotensin II (AII) and atrial natriuretic peptide …

We analyzed the internalization of the receptor subtype 2 (sst2) for the neuropeptide
somatostatin in glioma cells at the ultrastructural level using an antibody against an …
