Because of the biochemical colocalization of the 5-HT(3) receptor and antidepressants within raft-like domains and their antagonistic effects at this ligand-gated ion channel, we investigated the impact of lipid raft integrity for . . . → Read More: Impact of lipid raft integrity on 5-HT3 receptor function and its modulation by antidepressants.

Long-Evans rats acquire operant self-administration of 20% ethanol without sucrose fading.

Simms JA, Bito-Onon JJ, Chatterjee S, Bartlett SE.
A major obstacle in the development of new medications for the treatment of alcohol use disorders (AUDs) has been the lack of preclinical, oral ethanol consumption paradigms that elicit high consumption. We have previously shown that rats exposed to 20% ethanol intermittently in a two-bottle choice paradigm will consume . . . → Read More: Long-Evans rats acquire operant self-administration of 20% ethanol without sucrose fading.

TrkB-BDNF-dependent striatal plasticity and behavior in a genetic model of epilepsy: modulation by valproic acid.

Ghiglieri V, Sgobio C, Patassini S, Bagetta V, Fejtova A, Giamp? C, Marinucci S, Heyden A, Gundelfinger ED, Fusco FR, Calabresi P, Picconi B.
In mice lacking the central domain of the presynaptic scaffold Bassoon the occurrence of repeated cortical seizures induces cell-type-specific plasticity changes resulting in a general enhancement of the feedforward inhibition within the . . . → Read More: TrkB-BDNF-dependent striatal plasticity and behavior in a genetic model of epilepsy: modulation by valproic acid.

The expression of VGF is reduced in leukocytes of depressed patients and it is restored by effective antidepressant treatment.

Cattaneo A, Sesta A, Calabrese F, Nielsen G, Riva MA, Gennarelli M.
Major depression is a disease characterized by an inability of neuronal systems to show appropriate adaptive plasticity especially under challenging conditions, such as stress. Conversely, pharmacological intervention may normalize such defects through the modulation of factors that might act in concert for the functional . . . → Read More: The expression of VGF is reduced in leukocytes of depressed patients and it is restored by effective antidepressant treatment.
