Interleukin 6 modulation of second messenger systems in anterior pituitary cells

Autor: Gennaro Schettini, C. Ventra, Tullio Florio, Renato De Mercato, Maurizio Grimaldi, Olimpia Meucci, Antonella Scorziello

Publikováno v: Life Sciences. 51:1243-1248

We investigated the effect of interleukin-6 (IL-6) on second messenger systems in anterior pituitary (AP) cells. The acute exposition of membranes derived from the pituitary gland to IL-6 did not modify basal and forskolin-stimulated adenylate cyclas

Immortalized Hypothalamic Neurons Express Metabotropic Glutamate Receptors Positively Coupled to Cyclic AMP Formation

Autor: Thomas Knöpfel, G. Casabona, F. Nicoletti, Agata Copani, Maria Angela Sortino, Pier Luigi Canonico, Grazia Aleppo, C. Ventra, Rainer Kuhn, Barbara Malitschek

Publikováno v: European Journal of Neuroscience. 8:2407-2415

We have characterized the expression pattern and pharmacological profile of activation of metabotropic glutamate receptors (mGluRs) in immortalized, gonadotropin releasing hormone (GnRH)-secreting GT1-7 cells, which represent a homogeneous cellular p

Direct effect of adenosine on prolactin secretion at the level of the single rat lactotroph: involvement of pertussis toxin-sensitive and -insensitive transducing mechanisms

Autor: C. Ventra, E. Landolfi, Alfredo Postiglione, Antonella Scorziello, Gennaro Schettini, Olimpia Meucci, A. Avallone, Maurizio Grimaldi

Publikováno v: Scopus-Elsevier

We studied the effect of adenosine on prolactin secretion by the anterior pituitary, and the transduction mechanisms whereby the purine exerts its action. Adenosine inhibited prolactin release in basal and in vasoactive intestinal peptide (VIP)- or T

Modulation by GTP of Basal and Agonist-Stimulated Striatal Adenylate Cyclase Activity Following Chronic Blockade of D1 and D2 Dopamine Receptors: Involvement of G Proteins in the Development of Receptor Supersensitivity

Autor: Tullio Florio, Gennaro Schettini, Olimpia Meucci, Maurizio Grimaldi, C. Ventra, A. Marino

Publikováno v: Journal of Neurochemistry. 59:1667-1674

Rats receiving injections of specific antagonists of dopamine receptors (SCH 23390 for D1, haloperidol for D2, and haloperidol+SCH 23390) once daily for 21 days develop a selective supersensitivity of the blocked receptors. To study the molecular cor

Adenosine and its analogue ( − )-N6-R-phenyl-isopropyladenosine modulate anterior pituitary adenylate cyclase activity and prolactin secretion in the rat

Autor: A. Marino, Gennaro Schettini, Tullio Florio, E. Landolfi, C. Ventra, Olimpia Meucci, Maurizio Grimaldi

Publikováno v: Journal of Molecular Endocrinology. 5:69-76

The effect of adenosine and its analogue ( − )-N6-R-phenylisopropyladenosine (PIA) on both anterior pituitary adenylate cyclase activity and prolactin secretion was examined in the rat. Adenosine inhibited basal adenylate cyclase activity in a dose

Absence of D2S dopamine receptor in the prolactin-secreting MMQ pituitary clone: characterization of a wild D2L receptor coupled to native transduction mechanisms

Autor: Antonella Scorziello, Maurizio Grimaldi, C. Ventra, Olimpia Meucci, Gennaro Schettini, Antonio Porcellini

We used the PCR amplification technique in an attempt to characterize further the dopamine D2L receptor expressed in the prolactin-secreting pituitary MMQ cell clone, derived from the prolactinand ACTH-secreting Buffalo rat 7315a pituitary tumour. By

Aniracetam improves behavioural responses and facilitates signal transduction in the rat brain

Autor: A. Marino, Antonella Scorziello, Maurizio Grimaldi, Emilio Filetti, Antonio Apicella, Gennaro Schettini, C. Ventra, Olimpia Meucci

The effect of aniracetam (10, 50, 100 mg/kg i.p. daily for 15 days) on both behavioural and biochemical parameters was investigated in the adult rat. Animals given aniracetam (50 mg/kg 1 h before the trial) showed a significant increase in the percen
