摘要
肠铁吸收及调节机制是机体维持铁稳态的关键环节.对非血红素铁的吸收及调控机制研究较多,而对血红素铁的报道较少,对其吸收及调控机制还需深入研究.本文依据最新的研究进展,介绍了血红素铁的肠铁吸收途径及其调控机制,希望对预防和治疗铁代谢相关疾病提供基础资料.
Intestinal iron absorption and its regulation are the key step in iron homeostasis. A large number of reports are involved in the absorption and regulation mechanism of non-heme iron; however, those of heme iron are much less, which still remains to be elucidated. Thus, the study of heme iron absorption and regulation has received much attention in recent years. This review summarizes the possible pathways and molecular mechanisms of heme intake by small intestine and its regulation according to the latest research progress. It will facilitate the understanding of iron absorption especially heme iron and regulation mechanism by intestine, which is important to prevention and treatment of iron metabolism disorders and iron-related diseases.
