为评估水性佐剂GEL 01对猪支原体肺炎活疫苗的黏膜接种效果的影响,本研究以小鼠为动物模型,将猪肺炎支原体(168株)活疫苗与水性佐剂GEL 01滴鼻免疫小鼠,于免疫后不同时间点收集血清和支气管肺泡灌洗液,检测其中抗原特异性抗体水平和相... 为评估水性佐剂GEL 01对猪支原体肺炎活疫苗的黏膜接种效果的影响,本研究以小鼠为动物模型,将猪肺炎支原体(168株)活疫苗与水性佐剂GEL 01滴鼻免疫小鼠,于免疫后不同时间点收集血清和支气管肺泡灌洗液,检测其中抗原特异性抗体水平和相关细胞因子的分泌情况,并检测了GEL 01对小鼠淋巴细胞增殖的影响。结果显示Gel 01联合活疫苗黏膜接种后,支气管肺泡灌洗液中抗原特性抗体(IgG、IgG1、IgG2a和sIgA)的水平显著高于单独疫苗组,同时支气管肺泡灌洗液中Th1(IFN-γ)型、Th2(IL-4)型和Th17(IL-17)型细胞因子分泌显著增加;另外,GEL 01联合猪肺炎支原体活疫苗黏膜接种后,促进小鼠淋巴细胞的显著增殖,并同时上调血清中IgG、IgG1、IgG2a抗体水平。以上结果说明GEL 01作为黏膜佐剂配合猪支原体肺炎活疫苗使用时,可全面激活宿主免疫系统,尤其是与猪肺炎支原体感染免疫保护相关的呼吸道局部黏膜免疫和全身循环系统的细胞免疫。 展开更多

Porcine reproductive and respiratory syndrome (PRRS) is a devastating disease caused by the PRRS virus. The MontanideTM class of flexible polymeric adjuvants has recently been shown to enhance protective immunity against PRRSV infection in piglets when used in combination with PRRS modified live vaccines (MLV). In this study, we explored the efficacy and immunological mechanisms of protection of MontanideTM Gel01 ST (Gel01) adjuvanted modified live PRRSV vaccine in pigs challenged with two genetically distinct strains of PRRSV. Gel01-MLV reduced lymph node pathology scores in pigs challenged with VR-2332 (parental strain of MLV vaccine) but not that in pigs challenged with MN184A (heterologous strain), when compared to that in pigs vaccinated with un-adjuvanted MLV. Pigs vaccinated with Gel01-MLV had higher levels of PRRS-specific antibodies, as measured by IDEXX ELISA and virus neutralizing antibodies, after vaccination and VR-2332 challenge. In addition, pigs vaccinated with Gel01-MLV had decreased levels of IFN-γ, IL-10, and T-regulatory lymphocytes in the blood as compared to that in pigs vaccinated with MLV alone. Interestingly, we found that addition of Gel01 did not change the profile of other T lymphocyte populations after PRRSV challenge. These results demonstrate that the MLV adjuvanted with Gel01 provides enhanced protection against homologous PRRSV infection, possibly by regulating the production of PRRSV-specific antibodies and cytokines involved in the development of T-regulatory cells. Thus, Gel01 ST is a promising adjuvant that can be formulated with PRRSV MLV vaccines to reduce disease severity and tissue damage caused by PRRSV infection in pigs. 展开更多
