    Notes: Abstract: The GABAA receptor, as assessed by ligand binding and chloride flux measurement in vivo and in vitro, is down-regulated in response to chronic benzodiazepine exposure. The mRNA levels of the α1 and γ2 subunits of the receptor are also reduced. We have isolated the promoter of the gene encoding the α1 subunit of the GABAA receptor to elucidate the regulatory mechanism of its expression. A DNA segment 650 bp long has been Isolated that includes 151 bp of untranslated 5’end of the cDNA sequence and 500 bp of potential promoter-enhancer region. The transcriptional activity of this DNA segment linked to the firefly luciferase gene showed a strong orientation specificity. The promoter activity was localized to a 60-bp segment by deletion mapping. Mobility shift binding assay results suggest that this segment may interact with one or more factors in HeLa cell nuclear extracts to form a transcriptional complex. Primary cultures of embryonic chick cortical cells transfected with the promoter-luciferase construct were treated chronically with lorazepam. Transcriptional activity of this promoter construct was strongly repressed by chronic administration of lorazepam.

    Notes: Abstract: The N-methyl-D-aspartate (NMDA) receptor of rat cerebellar granule cells in primary culture is inhibited by phospholipase C-coupled receptor activation. In the absence of ionotropic agonist, cells modulate their cytoplasmic free Ca2+, [Ca2+]c, in response to stimulation of M3 muscarinic receptors, metabotropic glutamate receptors, and endothelin receptors by the respective agonists carbachol, trans-l-amino-l,3-cyclopentanedicarboxylic acid, and endothelin-1. The response is consistent with the ability of phospholipase C-coupled receptors to release a pool of intracellular Ca2+ and induce a subsequent Ca2+ entry into the cell; both of these responses can be abolished by discharge of internal Ca2+ stores with low concentrations of ionomycin or thapsigargin. In the case of cells stimulated with NMDA, the [Ca2+]c response to the phospholipase C-coupled agonists is complex and agonist dependent; however, in the presence of ionomycin each agonist produces a partial inhibition of the NMDA component of the [Ca2+]c signal. This inhibition can be mimicked by the protein kinase C activator 4β-phorbol 12,13-dibutyrate. It is concluded that NMDA receptors on cerebellar granule cells are inhibited by phospholipase C-coupled muscarinic M3, glutamatergic, and endothelin receptors via activation of protein kinase C.

    Notes: To test the specificity of N-acetylaspartate (NAA) as a neuronal marker for proton nuclear magnetic resonance (1H NMR) spectroscopy, purified and characterized cultured cells were analyzed for their NAA content using both 1H NMR and HPLC. Cell types studied included cerebellar granule neurons, type-1 astrocytes, meningeal cells, oligodendrocyte-type-2 astrocyte (O–2A) progenitor cells, and oligodendrocytes. A high concentration of NAA was found in extracts of cerebellar granule neurons (approximately 12 nmol/mg of protein), whereas NAA remained undetectable in purified type-1 astrocytes, meningeal cells, and mature oligodendrocytes. However, twice the neuronal level of NAA was found in O-2A progenitors grown in vitro. In addition significant levels of NAA were also detected in cultures of immature oligodendrocytes. Our data partly support previous suggestions that NAA may be a useful neuronal marker for 1H NMR spectroscopic examination of the adult brain. However, they also raise the further possibility that alterations of NAA associated with some specific brain disorders, particularly disorders seen in newborn and young children, may reflect abnormalities in the development of oligodendroglia or their precursors.

    Notes: Abstract: Tyrosine hydroxylase (TH)-mRNA, assayed by in situ hybridization combined with TH immunocytochemistry, showed a selective increase in the ventral tegmental area (A-10) but not in the substantia nigra (A-9) midbrain dopaminergic (DAergic) neurons 3 days after reserpine treatment. TH-mRNA in locus ceruleus noradrenergic (A-4) neurons was increased by reserpine, as confirmed by RNA blot hybridization. These findings show that TH-mRNA is differentially regulated in midbrain DAergic neurons in response to reserpine.

    Notes: Abstract: To determine whether astrocytes release nonprostanoid vasodilators, cells on microcarrier beads were superfused with various agents in the presence of indomethacin, and the effluent was bioassayed and also analyzed for nitric oxide by a chemiluminescence technique. Bradykinin and A23187 induced release of a factor that relaxed arterial rings, an effect that was blocked by hemoglobin. The effluent contained either nitric oxide or a related compound that could be reduced to nitric oxide. Production of this factor was competitively inhibited by the arginine analogs NG-nitro-L-arginine and NG-methyl-L-arginine and could be restored with L-arginine. Quisqualate and norepinephrine were also effective in causing the release of nitric oxide from astroglial cells. Thus, astrocyte-derived relaxing factor has properties similar to those of an endothelium- and neuronderived relaxing factor.

    Notes: Abstract: In the present study, the release of the neuropeptide cholecystokinin-8 (CCK) from purified nerve terminals (synaptosomes) of the rat hippocampus was characterized with respect to the subcellular distribution, the release upon addition of various agents, the release kinetics, the Ca2+ and ATP dependence of release, and the relationship between CCK release and elevations of intraterminal free Ca2+ concentration ([Ca]i). These characteristics were compared with those for the release of classical transmitters in similar preparations. CCK-like immunoreactivity (CCK-LI) is enriched in the purified synaptosomal fraction of hippocampus homogenates and released in a strictly Ca2+-dependent manner upon chemical depolarization, addition of 4-aminopyridine, or stimulation with the Ca2+ ionophore ionomycin. The presence of Ca2+ in the medium significantly stimulates the basal efflux of CCK-LI from synaptosomes. The release upon stimulation develops gradually in time with no significant release in the first 10 s and levels off after 3 min of depolarization. At this time, a large amount of CCK-LI is still present inside the synaptosomes. A correlation exists between the release of CCK-LI and the elevations of [Ca]i. The release of CCK-LI is decreased, but not blocked, upon ATP depletion. These characteristics markedly differ from those for classical transmitters, which show a fast component of Ca2+-dependent (exocytotic) release, an absolute dependence on cellular ATP, and no marked stimulation of basal efflux in the presence of Ca2+. Furthermore, the relationship between the volume average [Ca]i (measured with fura-2) and the extent of release is more or less linear for the release of CCK-LI, whereas this relationship is clearly nonlinear for the release of endogenous glutamate and γ-aminobutyric acid in similar preparations. We hypothesize that these differences between the neuropeptide CCK-8 and classical transmitters are caused by three differences: (a) vesicle type; (b) Ca2+ sensitivity of the release mechanism; and (c) release site.
