Positive allosteric modulators (PAMs) of metabotropic glutamate receptor subtype 5 (mGlu5) enhance N-methyl-d-aspartate receptor function and may represent a novel approach for the treatment of schizophrenia. ADX47273 [S-(4-fluoro-phenyl)-{3-[3-(4-fluoro-phenyl)-[1,2,4]oxadiazol-5-yl]-piperidin-1-yl}-methanone], a recently identified potent and selective(More)
Estrogens have long been implicated in influencing cognitive processes, yet the molecular mechanisms underlying these effects and the roles of the estrogen receptors alpha (ERalpha) and beta (ERbeta) remain unclear. Using pharmacological, biochemical and behavioral techniques, we demonstrate that the effects of estrogen on hippocampal synaptic plasticity(More)
One of the most recently identified serotonin (5-hydroxytryptamine (5-HT)) receptor subtypes is the 5-HT6 receptor. Although in-depth localization studies reveal an exclusive distribution of 5-HT6 mRNA in the central nervous system, the precise biological role of this receptor still remains unknown. In the present series of experiments, we report the(More)
Activation of glycogen synthase kinase 3beta (Gsk3beta) has been shown to be a key component in signaling pathways that underlie neurodegeneration and neurodegenerative disease. Conversely, inactivation of Gsk3beta by phosphoinositide 3-kinase (PI3K)/Akt is an important neuroprotective mechanism. Previous studies have shown that agonist activation of group(More)
Positive allosteric modulators of metabotropic glutamate receptor subtype 5 (mGlu5) have promising therapeutic potential. The effects of selective mGlu5 receptor positive allosteric modulators on signaling molecules in brain slices have not been previously reported. The current study demonstrated that the selective mGlu5 receptor positive allosteric(More)
Recent studies have reported that estrogen has antidepressant-like effects in animal models. In this study we used the highly selective ER beta agonist, WAY-200070, to examine the role of ER beta activation on brain neurochemistry and activity in antidepressant and anxiolytic models in male mice. Within 15 min of administration, WAY-200070 (30 mg/kg s.c.)(More)
Myocardial ischemia reperfusion (I/R) can induce altered expression of microRNAs (miRNAs). The miRNAs—miR-15a, miR-15b and miR-16 have been shown to play a role in apoptosis, although not in cardiac-related models. We investigated the roles of miR-15b in hypoxia/reoxygenation (H/R)-induced apoptosis of cardiomyocytes. Quantitative real time polymerase chain(More)
PURPOSE To characterize the regulatory effect of gammadelta T cells in the activation of IL-17+ uveitogenic T cells. METHODS The authors administered the gammadelta TCR-specific antibody GL3 to B6 mice before or after antigen immunization and examined Th1- or Th17-polarized T-cell responses. The intensity of Th17 responses was also examined in responder T(More)
Two double-stranded RNA (dsRNA) mycoviruses were found in isolate QSP5 of the rice blast fungus Magnaporthe oryzae. Sequence analysis of the two dsRNA mycoviruses revealed that one is closely related to Magnaporthe oryzae virus 2 (MoV2), and the other one is related to Magnaporthe oryzae chrysovirus 1-A (MoCV1-A). Therefore, they were named Magnaporthe(More)
Neurotrophins (NTs) induce gene transcription by binding their high-affinity tropomyosin-related kinase (Trk) receptors and initiating intracellular signal transduction cascades. In particular, activation of the cyclic AMP response element (CRE) in the promoters of target genes serves as surrogate markers for Trk receptor activation as demonstrated in both(More)
