“The continuous incorporation of new neurons https://www.selleckchem.com/products/elacridar-gf120918.html in the dentate gyrus of the adult hippocampus raises exciting questions about memory and learning, and has inspired new computational models to understand the function of adult neurogenesis. These theoretical approaches suggest distinct roles for new neurons as they slowly integrate into the existing dentate gyrus network: immature adult-born neurons seem to function as pattern integrators of temporally adjacent events, thereby enhancing pattern separation for events separated in time; whereas maturing adult-born neurons possibly contribute to pattern separation by being more amenable to learning new information, leading to dedicated groups of granule cells that respond to experienced environments. We review these hypothesized functions and supporting empirical research and point to new directions for future theoretical efforts.”
“Glycogen synthase kinase-3 beta (GSK-3 beta) is an enzyme that phosphorylates glycogen synthase, thereby inhibiting glycogen synthesis.

Besides this role, it is now believed that this enzyme plays an important role in the pathophysiology of many brain diseases including depression. Some inhibitors of this enzyme have shown antidepressant effects in animal models. This study investigated the effects of a novel thiadiazolidinone NP031115, a putative GSK-3 beta inhibitor, and the well-established GSK-3 beta inhibitor AR-A014418 in the mouse forced swimming test (FST), a model widely used to evaluate Amyloid precursor protein secretase antidepressant activity. find more We found that NP031115 had an IC(50) of 1.23 and 6.5 mu M for GSK-3 beta and GSK-3 alpha, respectively. NP031115 (0.5 and 5 mg/kg, i.p.), in a way similar to imipramine (15 mg/kg, i.p), fluoxetine (32 mg/kg, i.p), AR-A014418 (9 mg/kg, i.p.), and rosiglitazone (5 mu g/site, i.c.v.). significantly reduced immobility time in the

FST. NP031115 at the higher dose and AR-A014418 (9 mg/kg, i.p.) reduced locomotion in the open-field test. Rosiglitazone (30 mu M), AR-A014418 (1 mu M), PG(J2). (10 mu M), and NP031115 (1, 10 and 25 mu M) activate PPAR gamma in CHO transfected cells. GW-9662 (10 mu g/site, i.c.v, a PPAR gamma antagonist) administered 15 min before NP03115 (5 mg/kg, i.p.) or co-administered with rosiglitazone (5 mu g/site, i.c.v.) prevented the antidepressant-like effect of these drugs in the FST. The results of this study show that NP031115 can exhibit an antidepressant effect, likely by inhibiting GSK-3 beta and enhancing PPAR gamma activity. (C) 2008 Elsevier Inc. All rights reserved.”
“The formation of an olfactory recognition memory by female mice for the stud male pheromones requires two fundamental conditions: incidence of mating and retention of the stud male with the female for a critical 6 h interval following mating.
