Activation of the hypothalamic-pituitary-adrenal stress axis induces cellular oxidative stress

Frontiers in Neuroscience, 2015
Glucocorticoids released from the adrenal gland in response to stress-induced activation of the hypothalamic-pituitary-adrenal (HPA) axis induce activity in the cellular reduction-oxidation (redox) system.

Influence of mirtazapine on salivary cortisol in depressed patients [PDF]

, 2003
Unlike other antidepressants, mirtazapine does not inhibit the reuptake of norepinephrine or serotonin but acts as an antagonist at presynaptic alpha(2)-receptors, at postsynaptic 5-HT2 and 5-HT3 receptors, and at histaminergic H1 receptors. Furthermore,
