Methods Eukaryotic expression plasmid pCMVCD was constructed , and identified by re2 striction endoenzyme digestion. CD gene was transfected into NSCs from new2born Wistar rats using Lipofec2tamine2000. Positive clones (named NSCs/ CD cells) were screened by G418 presence. 52Fluorocytosine (52FC) ad2ministration of different concentrations were incubated with NSCs/ CD cells. NSCs/ CD cells viability ratios were mea2 sured by MTT assay.

Using cytochalasin D to prevent global actin from forming filamentous structures, the production of Heliothis armigera nuclear polyhedrosis virus in Hz-AM1 cells grown in the medium containing 0.5μg/ml CD was completely inhibited while its production was reduced to 10〓 in the presence of 0.1μg/ml CD by plaque assay. However, Western blotting revealed that the actin quantity in infected host cells treated or untreated with CD was almost identical. Additionally, CD had no effect on the DNA synthesis of HaNPV.

Western blot表明细胞松弛素D并不影响受染细胞中肌动蛋白的含量，Dot blot表明病毒DNA的合成也没有受到影响，但电子显微镜超薄切片发现在0.5ug／mL细胞松弛素D中形成的病毒粒子形态与正常的有明显区别，认为细胞松弛素D抑制棉铃虫核型多角体病毒的增殖是因为抑制病毒的DNA和蛋白组装成完整有感染性的病毒粒子，即丝状肌动蛋白对病毒粒子的脱壳和DNA的复制、转录没有影响，但对病毒粒子的组装是必须的。
