Many biological effects of taurine rely upon its cellular concentration, which is primarily controlled by taurine biosynthetic enzymes cysteine dioxygenase (CDO) and cysteine sulfinate decarboxylase (CSD) and taurine transporter (TauT). The cloning o

Tonicity-responsive enhancer-binding protein (TonEBP) was initially identified as a transcription factor involved in adaptation of renal cells to hypertonicity by activation of osmoprotective genes encoding proteins for accumulation of compatible osm

Cysteine sulfinate decarboxylase (CSD) is the rate-limiting biosynthetic enzyme of the pathway that forms taurine, a putative osmolyte in the kidney, which was previously localized in various segments of the nephron. Although CSD is known to be expre

Cells exposed to hyperosmotic conditions maintain their volume by accumulating organic osmolytes. Taurine is considered as an osmolyte in brain cells. Accumulation of other osmolytes (sorbitol, myo-inositol and betaine), was shown in renal cells to r

Sorbitol, myo-inositol, betaine, and taurine are held as organic osmolytes. When cells are exposed to a hyperosmotic medium, they accumulate these organic compounds and thus achieve osmotic equilibrium with the medium while maintaining their volume.

Immunocytochemistry of cysteine sulfinate decarboxylase was performed with a new rabbit antiserum that we have recently produced and characterized using as antigen an 11,000-fold purified fraction isolated from rat liver. This antiserum precipitated

The paraventricular nucleus (PVN) of the hypothalamus, where the CRF-containing neurosecretory cells controlling the hypothalamo-pituitary-adrenal (HPA) axis are located, receives a dense noradrenergic innervation from the A1 group of the caudal vent

It has previously been shown that immobilization and ether stress induce activation of the hypothalamo-pituitary-adrenal (HPA) axis and that this activation occurs subsequent to activation of brain stem catecholaminergic neurones. In the present stud

The release of endogenous noradrenaline in the anterior hypothalamus was studied with microdialysis perfusion in freely moving rats that were subjected to immobilization stress. Experiments were carried out in sham-adrenalectomized and adrenalectomiz

We have compared the effects of increasing doses of dexamethasone on the hemorrhage-induced stimulation of the corticotropic axis and the metabolism of the catecholamines of the A1 group in the ventrolateral medulla. Adrenocorticotropin was measured
