Synthetic 2-stranded RNA-a helical complex formed by duplexing homopolymers of polyriboinosinic and polyribocytidylic acids (poly I:C)-induced host resistance to foot-and-mouth disease virus when microgram quantities were injected into mice. There was a graded response as shown by titrations of polynucleotide complex or virus. Protection was effective for >48 hours after a single injection of polynucleotide complex. Survival and serum interferon titers were directly related.
由聚肌苷酸和聚胞苷酸(聚 I:C)的同聚物双链形成的合成双链 RNA - α 螺旋复合物,当将微克量注射到小鼠体内时,可诱导宿主对口蹄疫病毒产生抗性。如对多核苷酸复合物或病毒进行滴定所示,存在分级反应。单次注射多核苷酸复合物后,保护作用可持续超过 48 小时。存活率和血清干扰素滴度直接相关。
