The brain's major inhibitory neurotransmitter gamma-aminobutyric acid (GABA) and the brain-derived neurotrophic factor (BDNF) play important roles in several stress- related disorders. Magnetic resonance spectroscopy (MRS) allows for non-invasive quantification of GABA concentration in the brain. We investigated the relationship between GABA concentration in the left dorsolateral prefrontal...

Toward specific ways to combine ketamine and psychotherapy in treating depression

Hasler, Gregor

In: CNS Spectrums, 2020, vol. 25, no. 3, p. 445–447

In major depression, remission rate in response to monoaminergic antidepressant is around 50%. The lack of strong synergies between classical antidepressants and psychotherapy may be due to the molecular effects of classical antidepressants. They modulate synapses but they do not substantially influence synaptogenesis. They also increase brain-derived neurotrophic factor (BDNF). However, for...

Combined with anti‐Nogo‐A antibody treatment, BDNF did not compensate the extra deleterious motor effect caused by large size cervical cord hemisection in adult macaques

Beaud, Marie‐Laure ; Rouiller, Eric M. ; Bloch, Jocelyne ; Mir, Anis ; Schwab, Martin E. ; Schmidlin, Eric

In: CNS Neuroscience & Therapeutics, 2019, p. cns.13213

In spinal cord injured adult mammals, neutralizing the neurite growth inhibitor Nogo‐A with antibodies promotes axonal regeneration and functional recovery, although axonal regeneration is limited in length. Neurotrophic factors such as BDNF stimulate neurite outgrowth and protect axotomized neurons. Can the effects obtained by neutralizing Nogo‐A, inducing an environment favorable for...
