BDNF Alterations in Brain Areas and the Neurocircuitry Involved in the Antidepressant Effects of Ketamine in Animal Models, Suggest the Existence of a Primary Circuit of Depression

Abstract: Major depressive disorder is one of the primary causes of disability and disease worldwide. The therapy of depression is prevalently based on monoamine reuptake blockers; consequently, investigations aimed to clarify the aetiology of depression have mostly looked at brain areas innervated by monamines and brain circuitry involved in inputs and outputs of these areas. The recent approval of esketamine as a rapid-acting antidepressant drug in treatment-resistant depression, has definitively projected glutamaterg… Show more

“…BDNF is broadly expressed in the central nervous system and regulates synapsis, memory, learning and neuroprotection. BDNF and its receptor TrkB are crucially involved in depression aetiology and antidepressant's therapeutic mechanisms 22,34–36 . Various stress procedures reduce BDNF, whereas chronic treatment with antidepressants almost always increases BDNF in the hippocampus and frontal cortex.…”

“…BDNF and its receptor TrkB are crucially involved in depression aetiology and antidepressant's therapeutic mechanisms. 22,[34][35][36] The alterations in mTOR activity were also elucidated as BDNF is its upstream regulator, and mTOR phosphorylation is an intracellular signalling mechanism that modulates antidepressant efficiency in depressed animal models and humans. 24,37,38 As evaluated by the p-mTOR-specific antibody, the mTOR activity was notably increased in engeletin-treated mice than in CRS mice.…”
