Corticosterone (17-Deoxycortisol) is an orally active and adrenal cortex-produced glucocorticoid, which plays an important role in regulating neuronal functions of the limbic system (including hippocampus, prefrontal cortex, and amygdala). Corticosterone increases the Rab-mediated AMPAR membrane traffic via SGK-induced phosphorylation of GDI. Corticosterone also interferes with the maturation of dendritic cells and shows a good immunosuppressive effect.
Corticosterone (100 nM
30 min) via SGK phosphorylation of GDI at Ser-213, increases the formation of GDI-Rab4 complex, facilitating the functional cycle of Rab4 and Rab4-mediated recycling of AMPARs to the synaptic membrane[1]. Corticosterone (CORT) (1 µM
48 h) shows good immunosuppressive properties (functionally compromises maturation of BMDC), which impairs LPS-induced up-regulation of maturation-associated markers (MHC class II, B7.2, B7.1 and CD40)[2].
Corticosterone results in a marked reduction in the ability of BMDC cells to prime naive CD8+ T cells in vivo[2]. Corticosterone (0.03 or 1 mg/kg
s.c.
single) downregulates expression of BDNF mRNA in dentate gyrus and CA1 of rats[3]. Corticosterone (2.6 mg/kg
in animal feedings
8 days) restores ethanol intake and preference to approximately normal preoperative levels in adrenalectomy (ADX) rats[4].
