With the ability to deliver recombinant pro- tein products outside, DhpVB could make VP28 directly interact with the shrimp when injected into shrim- p. In order to test the protection potential, live DhpVB were injected into the marine shrimp Exopalamon carincauda Holthuis for three times and WSSV challenge was performed twice simultaneously at the last two injections of the bacteria. The results showed that DhpVB displayed statistically significant advantage over bacteria without VP28 after the second challenge with an average RI （Resistance index） of 0.67±0.08, compared with 0.41±0.09 of bacteria without VP28 （P 〈0.05）. The data suggested that a quasi-immune response may exist in E. carincauda and live bacteria carrying VP28 could enhance the shrimp resistance against WSSV.展开更多

The aim of this study was to test a nonviral gene transferring vector's function of delivering DNA into liver cells to provide an important clue for gene transfer in liver gene therapy. METHODS: The complex of DNA and DNA delivering protein was injected into mice through their tail veins. Then the mice were killed and their liver tissue was sec- tioned. The gene transferring results were detected using a confocal laser scanning microscope. RESULTS: Fluorescence analysis indicated that both DNA- membrane penetrating peptide (MPP) complex and DNA- hepatocyte specific receptor binding domain ( HSRBD) - MPP complex could go into liver cells. The fluorescence value of liver cells in the DNA-HSRBD-MPP group was higher than that in the DNA-MPP group. CONCLUSIONS; MPP can successfully deliver DNA and protein into cells, and MPP with a HSRBD can specifically deliver DNA into liver cells. These have laid a foundation for further study on the nonviral liver cell gene delivering system.展开更多
