    Notes: Zusammenfassung Monoaminhaltige Neurone konnten mit Hilfe der Fluoreszenz-Mikroskopie in Hirnstammgewebe, welches während mehrerer Tage in vitro gezüchtet wurde, nachgewiesen werden. Reserpin und Natriumborhydrid bewirkten eine deutliche Abnahme dieser Fluoreszenz. Diese Untersuchungen weisen darauf hin, dass Neurone, welche während mehrerer Tage in vitro gezüchtet wurden, die Fähigkeit haben, Monoamine zu speichern und/oder zu synthetisieren.

    Notes: Summary A study was made of the action of GABA on the membrane potential and resistance of satellite glial (SG) cells in cultures of rat dorsal root ganglia. GABA (10-4M) depolarized all SG cells tested without producing significant changes in membrane resistance. Similar results were obtained from astrocytes of cultured rat spinal cord and brain stem, although only half of the cells tested were depolarized by GABA. Bicuculline (10-5 and 10-6M) which blocked the GABA-depolarization on cultured dorsal root ganglion (DRG) neurons, also markedly reduced or blocked the action of GABA on SG cells. When GABA was tested in sodium-free bathing solution, the amino acid caused a depolarization of similar shape and amplitude as in normal (137 mM Na+) bathing fluid, indicating that uptake processes are probably not involved in producing the depolarization by GABA. It is suggested that the depolarizing action of GABA on glial cells is an indirect effect due to the release of potassium from adjacent neurons during the action of the amino acid.

    Notes: Summary Autoradiographic studies were conducted on the binding of3H-GABA and3H-muscimol in cultures of rat cerebellum. Binding sites for both substances were observed on many cerebellar neurones, such as Purkinje cells and interneurones, but not on glial cells. Binding of3H-GABA and3H-muscimol was inhibited by unlabelled GABA and by the GABA antagonist bicuculline.

    Notes: Summary Autoradiographic studies were made on the uptake of 3H-noradrenaline and 3H-GABA in rat cerebellum grown in tissue culture. GABA was taken up by Purkinje cells and interneurones as well as by glial cells. In contrast, 3H-noradrenaline was only accumulated by nerve fibres but not by neuronal cell bodies and by glial cells.

    Evidence for GABAB-receptors on cultured astrocytes of rat CNS: autoradiographic binding studies (1990)

    Notes: Summary The cellular localization of GABA-binding sites was studied in explant cultures of rat cerebellum, brain stem and spinal cord by means of autoradiography. Labelling of GABAB-sites was done with 3H(-)baclofen or 3H-GABA in presence of unlabelled bicuculline. Binding sites for these radio-ligands were found on many neurones and on a large number of astrocytes. Labelling of glial cells was usually weaker than that of neurones. Combining autoradiography with staining with anti-glial fibrillary acidic protein (GFAP) revealed that the glial cells labelled with 3H-baclofen or 3H-GABA were GFAP-positive. In contrast, when GABAA-sites were localized using 3H-GABA in presence of unlabelled baclofen, the GABAA-agonists 3H-muscimol and 3H-THIP, or the antagonist 3H-(+)-bicuculline, binding only occurred to neurones but not to astrocytes. Immunohistochemical investigations with the monoclonal antibody (bd-17) against the GABAA/benzodiazepine/chloride channel complex revealed that neurones were specifically stained whereas glial cells were immunonegative. From our observations it is suggested that astrocytes possess GABAB-receptors but there is little evidence for the existence of GABAA-sites on glial elements.

    Action of dopamine and serotonin on the membrane potential of cultured astrocytes (1987)

    Notes: Summary The actions of dopamine, apomorphine and serotonin on the membrane potential of cultured astrocytes from rat spinal cord and striatum were examined. All three compounds caused a hyperpolarization of the majority of astrocytes tested. A small number of cells was depolarized and on a relatively large number of cells the amines had no effect. The dopamine antagonists cis-flupenthixol and domperidone reversibly blocked the effects of dopamine whereas the action of serotonin was antagonized by ketanserin. It is therefore concluded that the effects of both amines are due to activation of specific dopamine and serotonin receptors, respectively. Our electrophysiological data together with autoradiographic binding studies provide evidence that astrocytes possess receptors for dopamine and serotonin in addition to adrenoceptors and histamine receptors.

    Notes: Summary By means of lightmicroscopic autoradiography we have studied the cellular localization of binding sites for 3H-serotonin and 3H-ketanserin in organotypic cultures of rat brain stem and spinal cord. In both types of cultures, a relatively great number of neurones revealed binding sites for 3H-serotonin which predominantly labels S1-receptors. 3H-ketanserin, an S2-antagonist was also bound to many neurones although to a lesser extent than 3H-serotonin. Binding sites for both radio-ligands were also observed on astrocytes. These findings together with electrophysiological investigations indicate that astrocytes possess serotonin receptors.

    Notes: Summary The cellular localization of cholinergic binding sites was studied in organotypic cultures of rat spinal cord and brain stem by means of autoradiography with radiolabelled muscarinic and nicotinic agonists and antagonists. Many astrocytes in both types of cultures showed intense labelling by 3H-acetylcholine in the presence of nicotine and the muscarinic antagonists 3H-pirenzepine, 3H-quinuclidinyl benzilate and 3H-propylbenzilcholine mustard. Incubation of the cultures with 3H-nicotine or 3H-acetylcholine in the presence of atropine also caused labelling of astrocytes. In addition to glial cells, many neurones showed binding of muscarinic and nicotinic agonists and antagonists. From our results it is suggested that astrocytes, besides neurones, possess both muscarinic and nicotinic receptors.

    Notes: Summary Explant cultures of rat spinal cord, brain stem and cerebellum were used to visualize GABAA-receptors by means of immunohistochemistry. For these studies we have incubated the cultures with the monoclonal antibody bd 17 against the β-subunit of the GABAA/benzodiazepine/chloride channel complex. In spinal cord cultures, many interneurones were immunoreactive whereas only a small number of large neurones, probably motoneurones was specifically stained. In brain stem cultures, groups of large and medium-sized neurones showed immunoreactivity. In cultures of cerebellum, a great number of neurones was specifically stained. Granule cells showed the strongest immunoreactivity whereas other neurones, presumably Purkinje cells and interneurones, were only moderately stained. The immunoreactivity was mainly confined to the cell bodies of the neurones while their processes were only weakly or not stained. In contrast to neurones, no immunoreactivity could be detected on astrocytes.
