Tyndallized Lactobacillus plantarum HY7712 restores whole body γ-irradiation-impaired Th cell differentiation in mice.
JOURNAL OF MICROBIOLOGY AND BIOTECHNOLOGY(2017)
摘要
In the present study, we investigated the effect of tyndallized HY7712 (tHY7712) on the expression of Th cell specific transcription factors and cytokines in whole-body gamma-irradiated mice. Oral administration of tHY7712 strongly recovered the.-irradiation-suppressed expression of helper T (Th) cell-and regulatory T cell-related transcription factors and cytokines, such as T-bet, Foxp3, IFN-gamma, TNF-alpha, and IL-10, and suppressed Th2 cell-associated transcription factor and cytokine GATA3 and IL-5, respectively. Furthermore, compared with the control, tHY7712 treatment also restored gamma-irradiation-impaired natural killer and cytotoxic T cell activities against YAC-1 tumor cells to 97.8% and 98.6%, respectively.
