Biological psychiatry. Neuropsychiatry description: We investigated the possible existence of endogenous compounds acting on benzodiazepine central receptors in the serum of patients with panic attacks or depression. Our results show the presence of a substance which inhibits the 3H-fiunitrazepam binding specifically in the samples taken from the patients’ groups, and which is not present in normal controls, in the range of concentrations used. This compound has a molecular weight below 1,000 daltons, is heat-stable, and resistant to proteolytic degradation. The demonstration of this inhibitor opens new perspectives in the study of the biochemistry of anxiety. publisher: Karger date: 1987 type: Article type: PeerReviewed identifier: Marazziti, Donatella and Pietrini, Pietro and Martini, Claudia and Giannaccini, Gino and Perugi, Giulio and Placidi, Gian Franco and Cassano, Giovanni Battista and Lucacchini, Antonio A 3h-flunitrazepam binding inhibitor is present in psychiatric patients’sera.
