项目摘要
Maintenance of mammalian homeostatic balance is a multi-faced process involving an interaction of many proteins, however the need for a balance and coordinated interaction of many proteins, however the need for a balance and coordinated interaction between members of the serine proteinase super family and their inhibitors, known as serpins occupy a central role. In mammalian systems where extensive data exists, both serine proteinases and serpins are known to regulate such important functions as the blood coagulation cascade, fibrinolysis, food digestion, fertilization, inflammatory and immune responses. Imbalances or deficiencies in function of either serine proteinases or serpins have resulted in diseases. Ticks encode proteinases or serpins to disrupt the host homeostatic balance to their advantage.For this reason, we examined the molecular cloning of tick-encoded serpins as a candidate for tick vaccine. By using rapid amplification of the cDNA (RACE method), two genes (HLS l and HLS 2) from H. longicornis were cloned. Both recombinant HLS l and 2 showed the anti-coagulant activities. Vaccinaion of rabbits with either recombinant HLS 1 or 2 expressed in Escherichia coli resulted in significant anti-tick immunity.At present, we have characterized 4 tick salivary gland proteins whose recombinant products were effective against tick. We are planning to use these 4 cocktail vaccine for prevent the transmission of pathogens.
哺乳动物体内平衡的维持是一个多方面的过程,涉及许多蛋白质的相互作用,然而许多蛋白质之间需要平衡和协调相互作用,然而丝氨酸蛋白酶超家族成员和它们的抑制物(称为蛇毒)之间的平衡和协调相互作用起着核心作用。在存在大量数据的哺乳动物系统中,丝氨酸蛋白酶和蛇都被认为调节血液凝固级联、纤溶、食物消化、受精、炎症和免疫反应等重要功能。丝氨酸蛋白酶或蛇的功能失衡或功能缺陷都会导致疾病。壁虱编码的蛋白水解酶或蛇破坏宿主的动态平衡对它们有利。为此,我们研究了壁虱编码的蛇的分子克隆作为壁虱疫苗的候选者。利用快速扩增技术(RACE法),克隆了长角鱼的两个基因(hls L和hls 2)。重组HLS L和2均显示出抗凝血活性。在大肠杆菌中表达的重组HLS-1或HLS-2疫苗免疫兔后,产生了显著的抗蜱免疫。目前,我们已鉴定了4种具有抗蚤活性的重组唾液腺蛋白。我们计划使用这4种鸡尾酒疫苗来预防病原体的传播。
