猪繁殖与呼吸综合征(PRRS)是对全球养猪业构成重大挑战的主要猪病之一。目前的PRRS灭活疫苗对PRRSV的保护作用有限。因此,通过适当的给药途径使用适当的佐剂可能有助于提高疫苗效力。本研究通过高密度发酵,在巴斯德毕赤酵母中高效表达了重组不耐热肠毒素rLTB的B亚基。在灭活的小鼠PRRS抗原上评估rLTB的鼻内佐剂特性。与单纯PRRS抗原免疫组相比,50µg rLTB可显著提高黏膜部位的抗原特异性IgA抗体,并增加血清中的抗体,以IgG2a和IgG2b亚类为主。此外,rLTB诱导Th1型(干扰素-γ和IL-12)和Th17(IL-6)细胞因子谱增加,但对Th2型细胞因子谱(IL-4和IL-10)影响不大。此外,rLTB鼻腔给药没有明显的毒性反应。我们的数据提供了证据,表明巴斯德毕赤酵母发酵产生的rLTB具有低毒性,其鼻内佐剂作用涉及免疫系统对Th1的调节。
Porcine reproductive and respiratory syndrome (PRRS) is one of the major swine diseases responsible for a significant challenge in the global swine industry. The current PRRS inactivated vaccine only confers limited protection against PRRSV. Thus, using an appropriate adjuvant via a suitable administration route may help improve vaccine efficacy. In this study, the recombinant B subunit of the Escherichia coli heat-labile enterotoxin rLTB, was highly expressed in Pichia pastoris, through high-density fermentation. rLTB intranasal adjuvant properties were evaluated on an inactivated PRRS antigen in mice. Compared to the group immunized with solely PRRS antigen, a dose of 50 µg rLTB remarkably raised antigen-specific IgA antibodies at mucosal sites, and increased serum IgG antibodies, preferentially the IgG2a and IgG2b subclasses. Further, rLTB induced increases in Th1- (IFN-γ and IL-12) and Th17 (IL-6) cytokine profiles, but had little effect on Th2 cytokine profiles (IL-4 and IL-10). Moreover, there were no overt toxicities associated with intranasal rLTB administration. Our data provide evidence that the rLTB produced by P. pastoris fermentation portrays low toxicity, and its intranasal adjuvant effect involves immune system modulation to a Th1 profile.
