摘要

Accumulating evidence strongly suggest that impaired glucocorticoid receptor (GR) signaling is involved in stress-related mood disorders, and nominate GR as a potential target for antidepressants (ADs). It is known that different classes of ADs affects the GR action via modifying its phosphorylation, while the mechanism through which ADs alter GR phosphorylation targeted by GSK3 beta, a kinase modulated via serotonin neurotransmission, are unclear. On this basis, we investigated whether GSK3 beta-GR signaling could be a convergence point of fluoxetine action on brain function and behavior, by examining its effect on GSK3 beta targeted-GR phosphorylation on threonine 171 (pGR171), and expression of GR-regulated genes in the hippocampus of female and male rats exposed to chronic isolation stress.
