Nucleotides and cysteinyl-leukotrienes (CysLTs) are unrelated signaling molecules inducing multiple effects through separate G-protein-coupled receptors: the P2Y and the CysLT receptors. Here we show that GPR17, a Gi-coupled orphan receptor at intermediate phylogenetic position between P2Y and CysLT receptors, is specifically activated by both families of(More)
NMDA receptors and Ca2+/calmodulin-dependent kinase II (CaMKII) have been reported to be highly concentrated in the postsynaptic density (PSD). Although the possibility that CaMKII in PSD might be associated with specific proteins has been put forward, the protein or proteins determining the targeting of the kinase in PSD have not yet been identified. Here(More)
Deciphering the mechanisms regulating the generation of new neurons and new oligodendrocytes, the myelinating cells of the central nervous system, is of paramount importance to address new strategies to replace endogenous damaged cells in the adult brain and foster repair in neurodegenerative diseases. Upon brain injury, the extracellular concentrations of(More)
A number of psychotropic drugs, particularly the phenothiazines and related antipsychotic compounds, inhibit a variety of calmodulin-dependent enzymes. The mechanism by which these compounds inhibit the activity of calmodulin is through a selective calcium-dependent binding to this protein. With the notable exception of certain stereoisomers, compounds that(More)
BACKGROUND AND PURPOSE Prophylactic administration of simvastatin has been shown to protect against brain damage and its long-lasting behavioral consequences in neonatal rats. To establish the drug treatment window, we evaluated the effectiveness of simvastatin administered at different intervals before and after stroke. Furthermore, we determined whether(More)
The distribution of nicotinic receptors in the brain and ganglia of the Cynomolgus monkey was studied by in situ hybridization and receptor autoradiography. A 35S-labeled antisense riboprobe for the mRNA of the alpha 3 subunit of the human nicotinic receptor, [3H]L-nicotine and [125]alpha-bungarotoxin were used as markers. The highest levels of alpha 3-mRNA(More)
OBJECTIVE In the present study, MRI has been used to investigate therapeutic intervention with statins in a model of permanent focal cerebral ischemia in rat. METHODS AND RESULTS Brain ischemia was induced in rats by the permanent occlusion of middle cerebral artery (MCAO) and the brain infarct size followed up in alive animals 2, 24, and 48 hours after(More)
The characterization of motor and cognitive dysfunctions following a neonatal ischemic injury is a prerequisite to investigate putative pharmacological interventions. To this end, in the present study, we evaluated the long-lasting behavioral alterations occurring after a hypoxic/ischemic injury obtained by the combination of monolateral carotid ligation(More)
Statins, the most widely used lipid lowering drugs, have been demonstrated to play a protective role in stroke. Animal studies confirmed the observations obtained in clinical trials and provided additional data on the putative mechanism/s of action underlying this beneficial effect. We have shown that simvastatin reduced the size of the infarct to a(More)
The present study was undertaken to evaluate whether in a neonatal model of stroke a prophylactic neuroprotective treatment with simvastatin modulates hypoxia-ischemia-induced inflammatory and apoptotic signaling. Procaspase-3 and cleaved caspase-3 expression showed a peak at 24 h and returned to control values after 5 days. Caspase-3 activity followed the(More)
