    通过细胞壁结合蜱抗冻蛋白免疫靶向革兰氏阳性病原体
    摘要:
    补充或调节宿主免疫反应的免疫剂已被证明具有强大的治疗潜力,尽管这种方式对细菌病原体的探索较少。我们描述了一种细菌结合蛋白在使免疫系统重新接触病原菌方面的应用。更具体地说,将半抗原与肩突硬蜱表达的一种蛋白质结合,称为肩胛硬蜱抗冻糖蛋白 (IAFGP),该蛋白对细菌肽聚糖上的d-丙氨酸残基具有高亲和力。我们发现该蛋白质的一个片段保留了高表面结合亲和力。此外,半抗原与该肽的结合导致半抗原显示在万古霉素抗性的细胞表面上粪肠球菌。半抗原展示然后诱导抗体的募集并促进免疫细胞对细菌病原体的摄取。这些结果证明了使用细胞壁结合剂作为一类细菌免疫疗法的基础的可行性。
