epitopes derived from polio virus and ovalbumin and included a synthetic built-in adjuvant consisting of two 16-carbon lipoamino acids. Vaccine candidates were able to induce significantly strong antibody responses in mice without the need for any additional adjuvant, carrier protein, or special pharmaceutical preparation (e.g., liposomes). Vaccine constructs were assembled either in a linear or in a branched
由恶性转化引起的某些肿瘤相关糖类抗原(TACA)的过表达为开发新型抗肿瘤疫苗提供了有希望的目标,提供了打破其固有的低免疫原性和克服免疫系统耐受性的能力。我们设计,合成并通过免疫学方法评估了许多完全合成的新型嵌合构建体,这些构建体包含最常见的TACA(称为Tn抗原)簇,这些簇共价附于源自脊髓灰质炎病毒和卵清蛋白的T细胞肽表位,并包括合成的在佐剂中由两个16-碳脂氨基酸组成。候选疫苗能够在小鼠中诱导明显较强的抗体反应,而无需任何其他佐剂,载体蛋白或特殊的药物制剂(例如脂质体)。
