摘要
Tuftsin是一种四肽(thrl - lysl - pro - arg),作为一种免疫增强分子,具有结合和激活许多免疫细胞的能力,包括巨噬细胞或单核细胞,中性粒细胞和树突状细胞。簇状蛋白的棕榈酰化作用进一步提高了其特异性靶向活性,并将其掺入脂质体的脂质双层中。携带丛状脂质体(tuft -脂质体)具有一些特性,使它们能够作为一种潜在的药物和疫苗载体。负载簇脂质体的抗微生物药物已被证明对许多传染病非常有效,包括结核病、利什曼病、疟疾、念珠菌病和隐球菌病。此外,tuft -脂质体还增加了抗癌药物依托泊苷对小鼠纤维肉瘤的活性。簇状脂质体对白细胞减少小鼠具有免疫增强作用,使免疫细胞恢复活力。此外,封装在tuftsin脂质体中的抗原通过增加T细胞增殖和抗体分泌显示出更大的免疫原性。考虑到它们的特异性靶向和免疫增强作用,丛状脂质体可能被用作有前途的药物和疫苗传递系统。
