{"title":"Dopamine receptors and psychiatric drug treatment.","authors":"E K Syvälahti","doi":"","DOIUrl":"","url":null,"abstract":"The established antipsychotic drugs act mainly by antagonizing dopamine mediated synaptic transmission in the brain. Increase in the rate of production of dopamine metabolites as well as the firing rate of dopamine-containing neurons can be interpreted as compensatory responses to an interruption of synaptic transmission at dopamine nerve terminals. The demonstration of involvement of limbic and cortical mechanisms in the antipsychotic activity of neuroleptic drugs is far more difficult than the involvement of nigro-striatal and tubero-infundibular mechanisms in the neurological and neuroendocrine effects of these drugs. Application of radioreceptor techniques to dopamine research has supported the findings obtained by other neuropsychopharmacological research techniques, providing more direct evidence of dopamine receptor blockade by neuroleptic drugs. Further research is needed especially in studying the nature of the time-dependent adaptive changes at the receptor sites as well as the differences between the different dopamine projections and neural systems in the brain. The different subtypes of dopamine receptors in the brain, currently called D1 and D2 dopamine receptors, seem to be parallel, although in many respects independently-acting regulatory systems. Dopamine D2 receptor-selective antagonists such as sulpiride seem to cause selective D2 receptor up-regulation. Prolactin secretion seems to be regulated by D2 dopamine receptors. The exact physiological role of D1 dopamine receptors as well as the clinical consequences of selective D1 antagonism is not known. Sulpiride and clozapine are examples of atypical neuroleptic compounds that have quite different profile of action, the former having strong and selective antidopaminergic action, the latter combining a number of non- dopaminergic mechanisms with rather slight effects on dopamine receptors.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":8084,"journal":{"name":"Annals of clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14042342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Central-type and peripheral-type benzodiazepine receptors. 中枢型和外周型苯二氮卓受体。

{"title":"Central-type and peripheral-type benzodiazepine receptors.","authors":"V Saano","doi":"","DOIUrl":"","url":null,"abstract":"The benzodiazepines had already been in wide use as anxiolytics and anticonvulsants for more than ten years before their site of action in the central nervous system, the benzodiazepine receptor, was discovered. Simultaneously, a binding site in the peripheral organs, e.g. heart, lungs and kidneys, was found. Although some benzodiazepines, such as diazepam, bind to both central and peripheral benzodiazepine receptors with a high affinity, these two binding sites exhibit quite different properties. It is already clear that the central benzodiazepine receptors are in many regions of the brain coupled with the receptors for gamma-amino butyric acid, and they mediate the acute actions of benzodiazepines in the central nervous system. Through them opposite effects, such as anxiety and convulsions, can also be evoked by using inverse agonists, e.g. some beta-carbolines. All these effects can be blocked with benzodiazepine receptor antagonists, some of which are already used as specific antidotes against benzodiazepine overdose. The multitude of pharmacological effects that can be produced through central benzodiazepine receptors provides a good opportunity for the development of new drugs. The role of the peripheral-type receptors is less clear, but it seems that they are connected with more slowly-appearing drug actions, such as modulation of cell proliferation. Now that endogenous ligands for both the central-type (a peptide called diazepam binding inhibitor; DBI) and for the peripheral-type (porphyrins) benzodiazepine receptors have been discovered, even more productive research can be expected.","PeriodicalId":8084,"journal":{"name":"Annals of clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13988341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
