Our study showed that hepatic stellate cells (HSCs) promote the healing of the liver after drug-induced acute injury. However, the relevant mechanisms by which this is accomplished remain unclear. The objective of this study was to investigate the role of the adoptive transfer of HSCs in acute liver injury and the underlying mechanisms for healing. It was found that adoptive transfer of HSCs resulted in an increase in Tregs and a decrease in Th17 cells. Liver insult was consistently attenuated by HSC treatment. HSC cultured medium induced Tregs from naive T cells and suppressed the differentiation of Th17 cells. This study demonstrated that the adoptive transfer of HSCs protected the liver from drug-induced acute injury. Promoting the differentiation of Tregs and suppressing the development of Th17 cells are possibly involved in the protective effect of adoptive transfer of HSCs.
我们的研究表明,肝星状细胞(HSCs)促进药物诱导的急性肝损伤后的肝脏愈合。然而,其具体机制尚不清楚。本研究旨在探讨 HSCs 过继转移在急性肝损伤中的作用及其愈合的潜在机制。结果发现,HSCs 的过继转移导致 Tregs 增加和 Th17 细胞减少。HSC 治疗始终减轻肝损伤。HSC 培养上清诱导幼稚 T 细胞分化为 Tregs,并抑制 Th17 细胞分化。本研究表明,HSCs 的过继转移可保护肝脏免受药物诱导的急性损伤。促进 Tregs 的分化和抑制 Th17 细胞的发育可能参与了 HSCs 过继转移的保护作用。
