problem. To solve this problem, several STn derivatives with N-acetyl modifications were synthesized and incorporated into a 20-amino acid MUC1 tandem repeat sequence. The modified STn-MUC1 glycopeptides were further connected to a carrier protein keyhole limpet hemocyanin (KLH). The immunological effects of these synthetic vaccine conjugates were evaluated using the BALB/c mouse model. The results showed
糖蛋白MUC1是抗肿瘤疫苗开发的有吸引力的靶标。但是,MUC1的免疫原性仍然很弱。为了解决该问题,合成了几种具有N-乙酰基修饰的STn衍

氨基酸的MUC1串联重复序列中。修饰的STn-MUC1糖肽进一步与载体蛋白匙孔戚血蓝蛋白(KLH)连接。使用BALB / c小鼠模型评估了这些合成疫苗偶联物的免疫学作用。结果表明,疫苗V2引起与天然STn-MUC1抗原交叉反应的
抗体的更高滴度。此外,引起的抗血清与STn-MUC1抗原阳性的肿瘤细胞反应,表明
碳水化合物抗原修饰策略可能具有克服天然MUC1糖肽弱免疫原性的潜力。
