Abstract
- 【Abstract】 Objective: To explore the changes of Treg-Th17 balance influenced by corticosterone, major ef-fect hormone of hypothalamic-pituitary-adrenal (HPA) axis under running stress. Methods: A total of 25 corticotropin-releasing hor-mone (CRH) wildtype (CRH+/+) and knockout (CRH-/-) mice were adopt and divided into 4 groups as follows: CRH+/+ ctrl, CRH+/+ stress, CRH-/- ctrl and CRH-/- stress. All mice in stress groups were under 2 h running. After 1 h, blood plasma in all groups was collected and the ex-pression of corticosterone and IL-17A was detected by ELISA. Meanwhile, unicell suspensions of peripheral lymph node and spleen in each group were prepared too and stained by PE-CD4 and FITC-CD25, then the changes of Treg (CD4+CD25+) in different groups were checked by flow cytometry; all data were statistically analyzed by the software of WinMDI 2.9, SPSS 11.5, Origin 7.5 and Matlab 2-D and 3-D plot function. Results: The levels of corticosterone were signifi-cantly higher in stress groups than that in correspond-ing control groups (P
