Glutamate N-methyl-D-aspartate (NMDA) receptor antagonists (competitive receptor antagonists, ion channel blockers, and glycine antagonists)--such as selfotel, aptiganel, eliprodil, licostinel and gavestinel--failed to show efficacy in clinical trials of stroke or traumatic brain injury. This failure has been attributed to the deficient properties of the(More)
Multiple sclerosis is an immune-mediated disorder of the central nervous system leading to progressive decline of motor and sensory functions and permanent disability. The therapy of multiple sclerosis is only partially effective, despite anti-inflammatory, immunosuppresive and immunomodulatory measures. White matter inflammation and loss of myelin, the(More)
Amyotrophic lateral sclerosis (ALS) is a devastating disorder of the central nervous system in middle and old age that leads to progressive loss of spinal motoneurons. Transgenic mice overexpressing mutated human Cu(2+)/Zn(2+) superoxide dismutase 1 (SOD1) reproduce clinical features of the familial form of ALS. However, changes in SOD1 activity do not(More)
Epilepsy, the most common neurological disorder in young humans, has its highest incidence during the first year of life. Antiepileptic drugs (AEDs) which are used to treat seizures in infants, children and pregnant women target ion channels, neurotransmitters and second messenger systems in the brain. The same targets regulate brain processes essential(More)
Experimental autoimmune encephalomyelitis reproduces in rodents the features of multiple sclerosis, an immune-mediated, disabling disorder of the human nervous system. No adequate therapy is available for multiple sclerosis, despite anti-inflammatory, immunosuppressive, and immunomodulatory measures. Increasingly glutamate is implicated in the pathogenesis(More)
Blockade of receptors for the excitatory neurotransmitter glutamate ameliorates neurological clinical signs in models of the CNS inflammatory demyelinating disease multiple sclerosis (MS). To investigate whether glutamate excitoxicity may play a role in MS pathogenesis, the cellular localization of glutamate and its receptors, transporters and enzymes was(More)
OBJECTIVE Sedative and anticonvulsant drugs, which inhibit N-methyl-D-aspartate receptor-mediated excitation or enhance GABA-mediated action, may cause apoptotic neurodegeneration in the developing mammalian brain. Here we explored whether such agents influence early postnatal neurogenesis. METHODS The N-methyl-D-aspartate antagonist MK801 and the GABA(More)
The mechanisms of neuronal degeneration following traumatic head injury are not well understood and no adequate treatment is currently available for the prevention of traumatic brain damage in humans. Traumatic head injury leads to primary (at impact) and secondary (distant) damage to the brain. Mechanical percussion of the rat cortex mimics primary damage(More)
Some cannabinoid receptor ligands and their distomers are direct-acting openers of SUR1 KATP channels., we examined the chronic effects of two cannabinoid receptor-1 (CB1) inverse agonists, rimonabant and ibipinabant, in hyperinsulinemic Zucker rats to determine their chronic effects on insulinemia. Rimon-abant and ibipinabant (10 mg·kg Ϫ1 ·day Ϫ1) elicited(More)
To reveal whether increased Ca2+ permeability of glutamate AMPA channels triggered by the transgene for GluR-B(N) induces decline in motor functions and neurodegeneration in the spinal cord, we evaluated growth, motor coordination, and spinal reflexes in transgenic GluR-B(N) and wild-type (wt) mice. To reveal whether the transgenic GluR-B(N) expression(More)
