Proteomic signature of the Dravet syndrome in the genetic Scn1a-A1783V mouse model.
2021
Abstract Background Dravet syndrome is a rare, severe pediatric epileptic encephalopathy associated with intellectual and motor disabilities. Proteomic profiling in a mouse model of Dravet syndrome can provide information about the molecular consequences of the genetic deficiency and about pathophysiological mechanisms developing during the disease course. Methods A knock-in mouse model of Dravet syndrome with Scn1a haploinsufficiency was used for whole proteome, seizure, and behavioral analysis. Hippocampal tissue was dissected from two- (prior to epilepsy manifestation) and four- (following epilepsy manifestation) week-old male mice and analyzed using LC-MS/MS with label-free quantificati…
Effects of 8-OH-DPAT on open field performance of young and aged rats prenatally exposed to diazepam: a tool to rveal 5-HT1a receptor function
2003
Central GABAergic and serotoninergic systems interact with one another and are implicated in controlling different behaviours. A gentle early long-lasting handling can prevent the deficits in locomotion and exploration in open field (O.F.) in 3-month-old male rats prenatally exposed to diazepam (DZ). Purpose of this study was to extend the research to older handled rats prenatally exposed to DZ and to assess the activity of 5-HT1A receptors (Rs), evaluating the performance in O.F. at 3 and 18 months of age following 8-OH-DPAT administration. A single daily s.c. injection of DZ (1.5 mg/kg) from gestation day 14 to gestation day 20 induced in aged, but not in young rats, a decrease in total d…

Hippocampal theta activity, learning and behavioral tendencies
2014
Trace eyeblink conditioning is a method that models a declarative, awareness-dependent form of learning. Hippocampal theta activity, an approximately 3.5 - 8.5 Hz oscillatory pattern in rabbits, has been associated with learning-related phenomena: arousal, attentional processes and association forming. In some studies theta-contingent training, given during a brain state rich in hippocampal theta oscillation, has improved the initial learning in trace eyeblink conditioning. However, other laboratories have failed to replicate this effect. This study explored the effects of theta-contingent conditioning and extinction on learning, and the connection between the magnitude of spontaneous hippo…
Clobetasol promotes neuromuscular plasticity in mice after motoneuronal loss via sonic hedgehog signaling, immunomodulation and metabolic rebalancing
2021
AbstractMotoneuronal loss is the main feature of amyotrophic lateral sclerosis, although pathogenesis is extremely complex involving both neural and muscle cells. In order to translationally engage the sonic hedgehog pathway, which is a promising target for neural regeneration, recent studies have reported on the neuroprotective effects of clobetasol, an FDA-approved glucocorticoid, able to activate this pathway via smoothened. Herein we sought to examine functional, cellular, and metabolic effects of clobetasol in a neurotoxic mouse model of spinal motoneuronal loss. We found that clobetasol reduces muscle denervation and motor impairments in part by restoring sonic hedgehog signaling and …
