Stabilization of polyriboinosinic-polyribocytidylic acid against enzymatic hydrolysis by addition of poly-1-lysine and carboxymethylcellulose (PICLC) resulted in a compound with marked adjuvanticity. The primary antibody response of rhesus monkeys to formalin-inactivated Venezuelan equine encephalomyelitis virus vaccine was significantly potentiated if the vaccine was combined with PICLC prior to vaccination. The antibody response was maintained at a significantly higher level than controls for 2.5 months postvaccination and paralleled immunological responses reported for live, attenuated (TC-83) vaccine.
通过添加聚-L-赖氨酸和羧甲基纤维素(PICLC)使聚肌苷酸-聚胞苷酸对酶促水解稳定,从而得到一种具有显著佐剂活性的化合物。如果在接种前将福尔马林灭活的委内瑞拉马脑炎病毒疫苗与PICLC联合使用,恒河猴对该疫苗的初次抗体反应会显著增强。接种疫苗后2.5个月,抗体反应维持在显著高于对照组的水平,且与减毒活疫苗(TC-83)报道的免疫反应相似。
