扁虱主要是一种强制供血的体外寄生虫,对人类和动物的健康有影响。除了因进食造成的直接损害外,一些硬体物种还可作为几种疾病的病原体的媒介,如引起莱姆病的疏螺旋体属螺旋体、由硬体传播的脑炎病毒、各种立克次体病原体,甚至巴贝斯虫等原生动物寄生虫。硬蜱在吸血动物中是独一无二的,因为它们的进食期很长,可能长达两周。在如此长的血液摄取期间,宿主发展了一系列机制来防止失血。节肢动物体外寄生虫反过来会在咬伤部位分泌唾液,帮助血液摄取。事实上,扁虱唾液代表着丰富的蛋白质来源,具有强大的药理作用,针对不同的凝血、血小板聚集和血管收缩机制。壁虱对脊椎动物宿主的适应导致它们的唾液分泌物中含有一种强大的蛋白质武器,这一点已经通过高通量方法进行了研究。所获得的知识可用于分离新的抗止血药。在此,我们从分子和细胞水平上综述了壁虱唾液止血药物及其特有的功能。
Ticks are mostly obligatory blood feeding ectoparasites that have an impact on human and animal health. In addition to direct damage due to feeding, some tick species serve as the vectors for the causative agents of several diseases, such as the spirochetes of the genus Borrelia causing Lyme disease, the virus of tick-borne encephalitis, various Rickettsial pathogens or even protozoan parasites like Babesia spp. Hard ticks are unique among bloodfeeders because of their prolonged feeding period that may last up to two weeks. During such a long period of blood uptake, the host develops a wide range of mechanisms to prevent blood loss. The arthropod ectoparasite, in turn, secretes saliva in the sites of bite that assists blood feeding. Indeed, tick saliva represents a rich source of proteins with potent pharmacologic action that target different mechanisms of coagulation, platelet aggregation and vasoconstriction. Tick adaptation to their vertebrate hosts led to the inclusion of a powerful protein armamentarium in their salivary secretion that has been investigated by high throughput methods. The resulting knowledge can be exploited for the isolation of novel antihemostatic agents. Here we review the tick salivary antihemostatics and their characterized functions at the molecular and cellular levels.
