神经递质已被证明可以调节免疫反应,因此与自身免疫性疾病密切相关。在这里,我们发现,多巴胺能神经元的耗竭显着促进肝iNKT细胞的激活和增强刀豆球蛋白A(Con A)诱导的肝损伤。多巴胺对iNKT细胞的抑制作用是通过D1样受体-PKA途径介导的。通过抗生素鸡尾酒清除肠道微生物群减少了肠道中多巴胺的合成并加剧了肝损伤,并且可以通过恢复肠道微生物群或补充D1样受体激动剂来恢复。我们的研究结果表明,由肠道微生物控制的外周多巴胺抑制iNKT细胞中IL 4和IFNγ的产生,并抑制iNKT细胞介导的肝炎。总之,我们提出了一个肠道微生物神经系统免疫系统调节轴调节自身免疫性肝炎。
Neurotransmitters have been shown to regulate immune responses, and thereby are critically related to autoimmune diseases. Here we showed that depletion of dopaminergic neurons significantly promoted activation of hepatic iNKT cells and augmented concanavalin A (Con A)-induced liver injury. The suppressive effect of dopamine on iNKT cells was mediated by D1-like receptor-PKA pathway. Clearance of gut microbiota by antibiotic cocktail reduced synthesis of dopamine in intestines and exacerbated liver damage, and that could be restored by recovery of gut microbiota or replenishment of D1-like receptor agonist. Our results demonstrate that peripheral dopamine controlled by gut microbes inhibits IL4 and IFNγ production in iNKT cells and suppresses iNKT cell-mediated hepatitis. Together, we propose a gut microbe-nervous system-immune system regulatory axis in modulating autoimmune hepatitis.
