3-Oxo-5β-cholanoic acid (Dehydrolithocholic acid)，胆汁酸代谢产物，通过直接与关键转录因子RORγt (Kd=1.13 μM) 结合抑制 TH17 细胞分化。
Treatment with 3-Oxo-5β-cholanoic acid significantly reduced the activity of the RORγt reporter. These data suggest that 3-Oxo-5β-cholanoic acid probably inhibits TH17 cell differentiation by physically interacting with RORγt, and inhibiting its transcriptional activity.
3-Oxo-5β-cholanoic acid (Dehydrolithocholic acid) (0.3% (w/w); p.o.; for 1 week) significantly reduces the percentage of ileal TH17 cells.
| Animal Model: | B6 Jax mice (with a faecal slurry containing SFB) |
| Dosage: | 0.3% (w/w) |
| Administration: | Gavaged; for 1 week |
| Result: | Significantly reduced the percentage of ileal TH17 cells. |
