The purpose of this study was to optimize the preparation conditions of Lycium barbarum polysaccharides liposome (LBPL) by response surface methodology (RSM) and to investigate the effect of LBPL activating function of peritoneal macrophages. LBPL was prepared using the reverse-phase evaporation method. The optimal preparation conditions of LBPL by RSM were(More)
The aim of this study was to investigate the optimizing preparation conditions of Ganoderma lucidum polysaccharide liposome (GLPL) with response surface methodology (RSM) and the immunological enhancement activity of GLPL. The immunological enhancement activity of GLPL on splenocyte proliferation was measured. The optimum formulation of GLPL, in which the(More)
The aim of this study was to investigate the optimizing preparation conditions and immunological enhancement activity of Rehmannia glutinosa polysaccharide liposome (RGPL). RGPL was prepared using the reverse-phase evaporation method and optimized using the response surface methodology. The immunological enhancement activity of RGPL on splenocyte(More)
Liposome-based vaccine delivery systems are known to enhance immune responses. Ganoderma lucidum polysaccharides (GLP) have been widely studied as immunomodulator and it could be as inducers of strong immune responses. In the research, GLP and ovalbumin (OVA) were encapsulated into liposome as vaccine and inoculated to mice. The magnitude and kinetics of(More)
Liposomes, one kind of vaccine adjuvants, have been demonstrated as effective adjuvants and vaccine delivery system. Immunization against PCV-2 has been studied intensely and found to be the most effective strategy for protecting pigs against PCV-2 infection. Inactivated vaccines represent a complex mixture of viral antigens closely resembling the native(More)
Adjuvants enhance immunogenicity and sustain long-term immune responses. As vital components of vaccines, efficient adjuvants are highly desirable. Recent evidence regarding the potential of carbon nanotubes (CNTs) to act as a support material has suggested that certain properties, such as their unique hollow structure, high specific surface area, and(More)
In previous researches, the results showed that Lycium barbarum polysaccharides (LBP) encapsulated with liposome could enhance the immune activity of LBP. Therefore, the present study was designed to investigate the effects of LBPL on spleen lymphocytes and macrophages of mice in vitro and evaluate the immunological adjuvant activity of PCV2 vaccine in(More)
This study aimed to optimize the preparation conditions of pachyman (PHY)-loaded poly(d,l-lactic acid) (PLA) (PHYP) nanospheres by response surface methodology, explore their characteristics, and assess their effects on splenic lymphocytes. Double emulsion solvent evaporation was used to synthesize PHYP nanospheres, and the optimal preparation conditions(More)
The activation of murine peritoneal macrophages by Ganoderma lucidum polysaccharides liposomes (GLPL) was investigated in vitro. After treatment with GLPL, the changes of the nitric oxide (NO) secretion and iNOS (inducible nitric oxide synthase) activity were evaluated. The results showed that NO production and iNOS activity of macrophages were enhanced(More)
The aim of this study was to optimize the preparation conditions of salidroside liposome with high encapsulation efficiency (EE) and to study the immunological enhancement activity of salidroside liposome as porcine circovirus type 2 virus (PCV-2) vaccine adjuvant. Response surface methodology (RSM) was selected to optimize the conditions for the(More)
