Publication El ISCIII suma con su adhesión a EBRAINS una nueva incorporación a las Infraestructuras Europeas de Investigación en Salud(2023-09-13) Instituto de Salud Carlos III. Gabinete de prensaEl Instituto de Salud Carlos III (ISCIII) se ha unido como miembro asociado a la Infraestructura Europea de Investigación EBRAINS, que surge del Proyecto Cerebro Humano (Human Brain Project, HBP), financiado por la Unión Europea (UE) y que lleva 10 años en funcionamiento para mejorar el estudio de las enfermedades neurológicas. La infraestructura EBRAINS trabaja para fomentar la investigación relacionada con el cerebro y facilitar la interpretación de los últimos descubrimientos científicos en neurología, con el objetivo de impulsar tanto el conocimiento científico como la innovación industrial, ofreciendo recursos y servicios a la comunidad investigadora en beneficio de los pacientes y la sociedad.Publication Pharmacological blockade of the fatty acid amide hydrolase (FAAH) alters neural proliferation, apoptosis and gliosis in the rat hippocampus, hypothalamus and striatum in a negative energy context.(Frontiers Media, 2015-03-27) Rivera, Patricia; Bindila, Laura; Pastor, Antoni; Pérez-Martín, Margarita; Pavón, Francisco-Javier; Serrano, Antonia; de la Torre, Rafael; Lutz, Beat; Rodríguez de Fonseca, Fernando; Suárez, Juan; [Rivera,P; Pavón,FJ; Serrano,A; Rodríguez de Fonseca,F; Suárez,J] UGC Salud Mental, Instituto de Investigación Biomédica (IBIMA), Universidad de Málaga-Hospital Universitario Regional de Málaga, Málaga, Spain.

The pharmacological effect of the fatty acid amide hydrolase (FAAH) inhibitor URB597, which limits the endocannabinoid degradation, was investigated in the present study. Cell proliferation (phospho-H3(+) or BrdU(+) cells) of the main adult neurogenic zones as well as apoptosis (cleaved caspase-3(+)), astroglia (GFAP(+)), and microglia (Iba1(+) cells) were analyzed in the hippocampus, hypothalamus and striatum of rats intraperitoneally treated with URB597 (0.3 mg/kg/day) at one dose/4-days resting or 5 doses (1 dose/day). Repeated URB597 treatment increased the plasma levels of the N-acylethanolamines oleoylethanolamide, palmitoylethanolamide and arachidonoylethanolamine, reduced the plasma levels of glucose, triglycerides and cholesterol, and induced a transitory body weight decrease. The hippocampi of repeated URB597-treated rats showed a reduced number of phospho-H3(+) and BrdU(+) subgranular cells as well as GFAP(+), Iba1(+) and cleaved caspase-3(+) cells, which was accompanied with decreased hippocampal expression of the cannabinoid CB1 receptor gene Cnr1 and Faah. In the hypothalami of these rats, the number of phospho-H3(+), GFAP(+) and 3-weeks-old BrdU(+) cells was specifically decreased. The reduced striatal expression of CB1 receptor in repeated URB597-treated rats was only associated with a reduced apoptosis. In contrast, the striatum of acute URB597-treated rats showed an increased number of subventricular proliferative, astroglial and apoptotic cells, which was accompanied with increased Faah expression. Main results indicated that FAAH inhibitor URB597 decreased neural proliferation, glia and apoptosis in a brain region-dependent manner, which were coupled to local changes in Faah and/or Cnr1 expression and a negative energy context.
