Ketamine-induction of synaptogenesis requires BDNF/TrkB-activation of Akt and mTOR signaling, resulting in increased translation of synaptic proteins, including GluA1, as well as Arc, which is required for the expansion and stabilization of spines.

WebJul 15, 2024 · Binding of fluoxetine (Flx) acts as a wedge that maintains the crossed transmembrane domain orientation that is compatible with signaling, which increases a probability of BDNF (brain-derived neurotrophic factor) binding and signaling. (C) Allosteric activation of BDNF signaling by antidepressants. WebIn the absence of GI microbes, central BDNF levels are reduced and this inhibits the maintenance of NMDAR production. A reduction of NMDAR input onto GABA inhibitory interneurons causes disinhibition of glutamatergic output which disrupts the central signal-to-noise ratio and leads to aberrant synaptic behaviour and cognitive deficits.
