INFORMATION

Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicólogos del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Recently, sigma-1 receptor modulators have been considered drugs with an interesting therapeutic potential for the treatment of anxiety. However, there is no clear information in preclinical studies about the possible effects of sigma-1 ligands on anxiety in experimental animal models. Therefore, the present study examined the effects of (+)SKF 10,047 (2-8 mg/kg, ip), a sigma-1 agonist, on anxiety, tested in two classical laboratory models (social interaction test and elevated plus maze). (+)SKF 10,047 (8 mg/kg) produced a significant decrease of social investigation in the "social interaction test", whereas in the "elevated plus maze", the drug (4 and 8 mg/kg) provoked a significant reduction in the number of entries into open arms, as well as in the time spent in this area, as compared with the control group, without affecting motor activity. Overall, these findings indicate that (+)SKF 10,047 exhibits an anxiogenic-like profile in mice. It is suggested that anxiogenic effects of this sigma-1 ligand could be related to its potent ability to modulate diverse neurotransmitter systems involved in anxiety regulation.

Efectos del (+)SKF 10,047, un agonista del receptor sigma-1, sobre la ansiedad evaluada en dos modelos de laboratorio en ratones. Los receptores sigma-1 han sido considerados recientemente como fármacos con un interesante potencial terapéutico para el tratamiento de la ansiedad. Sin embargo, no existe información clara en estudios preclínicos con respecto a los posibles efectos de los ligandos sigma-1 sobre la ansiedad en modelos animales experimentales. Por lo tanto, en este trabajo examinamos los efectos de la administración de (+)SKF 10,047 (2-8 mg/kg, ip), un agonista sigma-1, sobre la ansiedad evaluada en dos modelos clásicos de laboratorio (test de interacción social y laberinto elevado en cruz). (+)SKF 10,047 (8 mg/kg) produjo una reducción significativa de las conductas de investigación social en el "test de interacción social", mientras que en el laberinto elevado en cruz el fármaco provocó (4 y 8 mg/kg) una disminución significativa del número de entradas y del tiempo pasado en los brazos abiertos del laberinto, en comparación con el grupo control, sin afectar la actividad motora. Estos resultados indican que el (+)SKF 10,047 muestra un perfil ansiogénico en ratones. Se sugiere que los efectos ansiogénicos de este ligando sigma-1 podrían estar relacionados con su potente capacidad para modular diferentes sistemas de neurotransmisión implicados en la regulación de la ansiedad.
