Striatal modulation of BDNF expression using microRNA124a-expressing lentiviral vectors impairs ethanol-induced conditioned-place preference and voluntary alcohol consumption

Bahi, Amine ; Dreyer, Jean-Luc

In: European Journal of Neuroscience, 2013, p. -

Alcohol abuse is a major health, economic and social concern in modern societies, but the exact molecular mechanisms underlying ethanol addiction remain elusive. Recent findings show that small non-coding microRNA (miRNA) signaling contributes to complex behavioral disorders including drug addiction. However, the role of miRNAs in ethanol-induced conditioned-place preference (CPP) and voluntary...

Invasion of lesion territory by regenerating fibers after spinal cord injury in adult macaque monkeys

Beaud, Marie-Laure ; Rouiller, Eric M. ; Bloch, Jocelyne ; Mir, Anis ; Schwab, M.E. ; Wannier, Thierry ; Schmidlin, Eric

In: Neuroscience, 2012, vol. 27, p. 271–282

In adult macaque monkeys subjected to an incomplete spinal cord injury (SCI), corticospinal (CS) fibers are rarely observed to grow in the lesion territory. This situation is little affected by the application of an anti-Nogo-A antibody which otherwise fosters the growth of CS fibers rostrally and caudally to the lesion. However, when using the Sternberger monoclonal-incorporated antibody 32...

Hippocampus-specific deletion of tissue plasminogen activator “tPA” in adult mice impairs depression- and anxiety-like behaviors

Bahi, Amine ; Dreyer, Jean-Luc

In: European Neuropsychopharmacology, 2012, p. -

Anxiety and depression are multifactorial disorders that have become prominent health problems all over the world. Neurotrophic factors have emerged underlying pathogenesis of these diseases. Although a number of studies indicate that the hippocampus-brain-derived neurotrophic factor (BDNF) may be involved in these psychiatric illnesses, little is known about the molecular mediators of these...

Role of accumbens BDNF and TrkB in cocaine-induced psychomotor sensitization, conditioned-place preference, and reinstatement in rats

Bahi, Amine ; Boyer, Frederic ; Vijay, Chandrasekar ; Dreyer, Jean-Luc

In: Psychopharmacology, 2008, vol. 199, no. 2, p. 169-182

Background Brain-derived neurotrophic factor (BDNF) is involved in the survival and function of midbrain DA neurons. BDNF action is mediated by the TrkB receptor–tyrosine kinase, and both BDNF and TrkB transcripts are widely expressed in the rat mesolimbic pathway, including the nucleus accumbens (NAc) and the ventral tegmentum area (VTA). Objective BDNF was previously shown to be involved in...
