摘要
肝脏因其能再生而独特。这种再生使得发生非迭代肝损伤时不会形成伤疤。然而,当发生慢性肝损伤时,肝脏单纯的再生功能将发生故障,过量的细胞外基质蛋白将沉积在正常肝组织上。虽然在过去的三十年里已经发现了很多,对肝纤维化的机制研究尚未形成有效的治疗方法。肝移植是治疗晚期肝病的唯一方法。为了拓宽收集可能的治疗靶点,本文比较和对比了两种肝损伤时的肝创伤愈合反应:胎儿皮肤伤口无瘢痕愈合和成人皮肤口腔黏膜及瘢痕形成创面愈合。本文检测了肝脏和皮肤与体液和细胞因子、以及细胞外基质作用有关的伤口愈合。某些治疗靶标与肝纤维化和成人皮肤创面愈合相似,而其他治疗靶标是独特的,代表肝脏抗纤维化研究的新领域。特别是,透明质酸对肝纤维化及肝纤维化消解的作用的研究是必不可少的。

摘要: The liver is unique in that it is able to regenerate. This regeneration occurs without formation of a scar in the case of non-iterative hepatic injury. However, when the liver is exposed to chronic liver injury, the purely regenerative process fails and excessive extracellular matrix proteins are deposited in place of normal liver parenchyma. While much has been discovered in the past three decades, insights into fibrotic mechanisms have not yet lead to effective therapies; liver transplant remains the only cure for advanced liver disease. In an effort to broaden the collection of possible therapeutic targets, this review will compare and contrast the liver wound healing response to that found in two types of wound healing: scarless wound healing of fetal skin and oral mucosa and scar-forming wound healing found in adult skin. This review will examine wound healing in the liver and the skin in relation to the role of humoral and cellular factors, as well as the extracellular matrix, in this process. While several therapeutic targets are similar between fibrotic liver and adult skin wound healing, others are unique and represent novel areas for hepatic anti-fibrotic research. In particular, investigations into the role of hyaluronan in liver fibrosis and fibrosis resolution are warranted.
