Protection of shrimp from yellow head virus (YHV) infection has been demonstrated by injection and oral delivery of dsRNA-YHV protease gene (dsYHV) or shrimp endogenous gene (dsRab7). However, to achieve complete viral suppression and to prolong dsRNA activity, the development of an effective dsRNA delivery system is required. In this study, four cationic liposomes were synthesized and tested for their ability to increase dsRNA efficiency. The results demonstrated that entrapping dsYHV in a cholesterol-based cationic liposome gave the best protection against YHV infection when compared with other cationic lipids. The cholesterol-based cationic liposome-dsYHV (Chol-dsYHV) complex conferred YHV protection in a dose-dependent manner. Injection with Chol-dsYHV at 0.05µg dsYHV/g shrimp could give comparable level of YHV protection to the injection with 1.25µg naked dsYHV/g shrimp. The shrimp injected with Chol- dsYHV at 1.25µg dsRNA/g shrimp showed only 50% mortality at 60days post injection whereas the naked dsYHV at the same concentration gave 90% mortality. Thus, the liposome-entrapped dsYHV could lower an effective dsRNA concentration in viral protection and prolong dsRNA activity. In addition, encapsulating dsRab7 in the cholesterol-based cationic liposome could protect the dsRab7 from enzymatic digestion, and continuous feeding the shrimp with the diet formulated with the liposome-entrapped dsRab7 for 4days in the total of 960µg dsRab7/g shrimp could enhance YHV protection efficiency compared with the naked dsRab7. Our studies reveal that cholesterol-based cationic liposome is a promising dsRNA carrier to enhance dsRNA efficiency in both injection and oral delivery systems.
