Title

Blockade of indoleamine 2, 3-dioxygenase 1 ameliorates hippocampal neurogenesis and BOLD-fMRI signals in chronic stress precipitated depression

Overall design

The aim of this study was to investigate the molecular mechanism of indoleamine 2, 3-dioxygenase 1 in depression by using the chronic unpredictable mild stress (CUMS) model. C57BL/6J mice were divided into the following 2 groups: (1) control group, and (2) CUMS group. The CUMS stress procedure lasted for 6 weeks. Serum levels of tryptophan, serotonin, and kynurenine were measured using LC-MS (n = 6/group).
