Neurosteroids stress and depression

When activated macrophages start to secrete IL-1, which synergistically with CRH increases ACTH, [10] T-cells also secrete glucosteroid response modifying factor (GRMF), as well as IL-1; both increase the amount of cortisol required to inhibit almost all the immune cells. [11] Immune cells then assume their own regulation, but at a higher cortisol setpoint. The increase in cortisol in diarrheic calves is minimal over healthy calves, however, and falls over time. [58] The cells do not lose all their fight-or-flight override because of interleukin-1's synergism with CRH. Cortisol even has a negative feedback effect on interleukin-1 [10] —especially useful to treat diseases that force the hypothalamus to secrete too much CRH, such as those caused by endotoxic bacteria. The suppressor immune cells are not affected by GRMF, [11] so the immune cells' effective setpoint may be even higher than the setpoint for physiological processes. GRMF affects primarily the liver (rather than the kidneys) for some physiological processes. [59]

Benzodiazepines may influence neurosteroid metabolism by virtue of their actions on translocator protein (TSPO; "peripheral benzodiazepine receptor"). [59] The pharmacological actions of benzodiazepines at the GABA A receptor are similar to those of neurosteroids . Factors which affect the ability of individual benzodiazepines to alter neurosteroid levels may depend upon whether the individual benzodiazepine drug interacts with TSPO. Some benzodiazepines may also inhibit neurosteroidogenic enzymes reducing neurosteroid synthesis. [60]

When tested in vitro , 7-keto appears to activate the beta subset of the estrogen receptor (ERβ) with an EC 50 around 500μM which is partially blocked by exemestane (aromatase inhibitor or AI); there was no apparent activity on the classical subset (ERα) and parent DHEA and DHEAS were eqipotent. [45] As activity was hindered with an AI and there was efficacy in HepG2 cells but not Hep293 (expressing [46] and not expressing [47] aromatase, respectively) it is though that 7-oxo can be metabolized into an estrogen.
