Abstract: Ticks are blood-sucking ectoparasites that release a variety of anticoagulant substances to their hosts to prevent blood clotting for the convenience of their blood feeding. Serine protease inhibitors containing Kunitz domain secreted by ticks are important anticoagulant substances. For different ticks, various anticoagulant substances are produced in different organs targeting their specific coagulation factors at different binding sites. This article reviews the existing tick-derived anticoagulant substances containing the Kunitz domain, so as to provide a reference for discovering more such anticoagulant substances in tick origin in the future and studying the mechanism of tick-host interaction at the pharmacological level.

Key words: Tick, Anticoagulant, Kunitz domain, Serine protease inhibitor

摘要: 蜱是一类体外吸血寄生虫,在长期吸血的过程中蜱向宿主体内释放多种抗凝血物质来阻止宿主血液凝固。含有Kunitz结构域的丝氨酸蛋白酶抑制分子是蜱分泌的重要抗凝血物质。不同蜱种体内的抗凝血物质释放的部位、作用的凝血因子以及与凝血因子相结合的位点各有不同。通过对现有蜱源Kunitz结构域的抗凝血物质的综述,为今后发现更多的蜱源Kunitz型抗凝血物质,并在药理水平上研究蜱与宿主之间相互作用的机制提供参考。
