Abstract

We examined rotavirus-specific IFN-gamma producing CD4+, CD8+ and CD4+CD8+ T cell responses in gnotobiotic pigs infected with a virulent human rotavirus (VirHRV) or vaccinated with an attenuated (Att) HRV vaccine (AttHRV3x or AttHRV2x) or an AttHRV oral priming and 2/6-virus-like particle (VLP) intranasal boosting (AttHRV-2/6VLP) regimen. In VirHRV infected pigs, HRV-specific IFN-gamma producing T cells reside primarily in ileum. AttHRV-2/6VLP induced similar frequencies of intestinal IFN-gamma producing T cells as the VirHRV, whereas AttHRV3x or 2x vaccines were less effective. Protection rates against rotavirus diarrhea upon VirHRV challenge significantly correlated (r=0.97-1.0, p<0.005) with frequencies of intestinal IFN-gamma producing T cells, suggesting their role in protective immunity.

摘要

我们检测了无菌猪感染强毒力人轮状病毒(VirHRV)或接种减毒(Att)HRV疫苗(AttHRV3x或AttHRV2x)或AttHRV口服初免和2/6病毒样颗粒(VLP)鼻内加强免疫(AttHRV-2/6VLP)方案后,产生IFN-γ的轮状病毒特异性CD4⁺、CD8⁺和CD4⁺CD8⁺T细胞反应。在感染VirHRV的猪中,产生HRV特异性IFN-γ的T细胞主要存在于回肠。AttHRV-2/6VLP诱导产生肠道IFN-γ的T细胞频率与VirHRV相似,而AttHRV3x或2x疫苗效果较差。VirHRV攻击后针对轮状病毒腹泻的保护率与肠道产生IFN-γ的T细胞频率显著相关(r=0.97-1.0,p<0.005),表明它们在保护性免疫中的作用。
