Single administration of low-dose ketamine has both acute and sustained anti-depressant effects. Sustained effect is associated with restoration of glutamatergic synapses in medial prefrontal cortic (mFPC) neurons. Ketamine induced profound changes in a number of molecular pathways in a mouse model for chronic stress. Cell-cell communication analyses predicted that planar-cell-polarity (PCP)...
Agmatine is a neuromodulator that has been proposed as a therapeutic strategy for the treatment of major depressive disorder (MDD). A previous study reported that agmatine caused a fast-acting effect in mice subjected to chronic mild stress without causing changes in the levels of synaptic proteins in the prefrontal cortex. We examined whether a single administration of agmatine is able to...
Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is one of the most robust neurobiological findings in the pathophysiology of major depressive disorder (MDD) over the last 40 years. The persistent increase in glucocorticoids levels induces morphological and anatomical changes in the brain, especially in the hippocampus. Ketamine represents a major advance for the treatment of MDD,...
