The present invention provides a method for identifying an agent to be tested for an ability to treat a psychotic disorder in a patient in need of such treatment. The invention provides a method for screening candidate drugs for anti-psychotic drug activity, preferably atypical anti-psychotic activity, comprising contacting cells or tissues with a candidate drug, determining levels of phosphorylation of the intracellular signaling proteins, DARPP-32, ERK1, ERK2 and CREB, in said cells or tissues and determining the pattern of the levels of phosphorylation of the proteins. The pattern of the levels of phosphorylation of DARPP-32, ERK1, ERK2 and CREB is, in certain embodiments, compared with the pattern of the levels of phosphorylation of DARPP-32, ERK1, ERK2 and CREB in the presence of an atypical anti-psychotic drug.

La présente invention concerne un procédé permettant d'identifier un agent devant être testé afin de déterminer s'il peut être utilisé pour traiter un trouble psychotique chez un patient nécessitant un tel traitement. Cette invention concerne un procédé de criblage de médicaments potentiels pour rechercher l'activité d'un médicament antipsychotique, de préférence, une activité antipsychotique atypique. Ce criblage consiste à mettre en contact des cellules ou des tissus avec un médicament potentiel; à déterminer les niveaux de phosphorylation des protéines de signalisation intracellulaire, DARPP-32, ERK1, ERK2 et CREB, dans lesdites cellules ou dans lesdits tissus; puis, à déterminer le dessin des niveaux de phosphorylation des protéines. Le dessin des niveaux de phosphorylation de DARPP-32, ERK1, ERK2 et CREB est, dans certains modes de réalisation, comparé au dessin des niveaux de phosphorylation de DARPP-32, ERK1, ERK2 et CREB en présence d'un médicament antipsychotique atypique.
