The Deficiency of Indoleamine 2,3-Dioxygenase Aggravates the CCl(4)-Induced Liver Fibrosis in Mice
In the present study, we examined the role of indoleamine 2,3-dioxygenase (IDO) in the development of CCl(4)-induced hepatic fibrosis. The liver fibrosis induced by repetitive administration with CCl(4) was aggravated in IDO-KO mice compared to WT mice. In IDO-KO mice treated with CCl(4), the number...

Sumario: | In the present study, we examined the role of indoleamine 2,3-dioxygenase (IDO) in the development of CCl(4)-induced hepatic fibrosis. The liver fibrosis induced by repetitive administration with CCl(4) was aggravated in IDO-KO mice compared to WT mice. In IDO-KO mice treated with CCl(4), the number of several inflammatory cells and the expression of pro-inflammatory cytokines increased in the liver. In the results, activated hepatic stellate cells (HSCs) and fibrogenic factors on HSCs increased after repetitive CCl(4) administration in IDO-KO mice compared to WT mice. Moreover, the treatment with l-tryptophan aggravated the CCl(4)-induced hepatic fibrosis in WT mice. Our findings demonstrated that the IDO deficiency enhanced the inflammation in the liver and aggravated liver fibrosis in repetitive CCl(4)-treated mice. |
