产肠毒素大肠杆菌(ETEC)是引起仔猪腹泻的主要病原体。F4(+) ETEC的主要亚基和粘附素FaeG是重要的毒力因子,具有较强的免疫原性。为了确定乳酸乳球菌(Lactococcus lactis, L. lactis)是否能有效地将FaeG传递到粘膜免疫系统,我们构建了表达FaeG的重组乳酸乳球菌(Lactococcus lactis),并探讨了重组乳酸乳球菌口服给药后小鼠的免疫反应。经Western blot分析,乳杆菌中表达的FaeG的产量约为可溶性全细胞蛋白的10%,重组FaeG (rFaeG)具有良好的免疫反应性。用表达FaeG的重组乳杆菌口服免疫小鼠可诱导f4特异性粘膜和全身免疫反应。此外,高剂量重组乳酸乳杆菌或高剂量重组乳酸乳杆菌与CTB共给药可增强免疫应答。这些结果表明,表达FaeG的乳酸乳杆菌是一种很有希望的ETEC候选疫苗。
Enterotoxigenic Escherichia coli (ETEC) is a major pathogenic agent causing piglet diarrhea. The major subunit and adhesin FaeG of F4(+) ETEC is an important virulence factor with strong immunogenicity. To determine whether Lactococcus lactis (L. lactis) could effectively deliver FaeG to the mucosal immune system, recombinant L. lactis expressing FaeG was constructed, and immune responses in mice following oral route delivery of recombinant L. lactis were explored. The production of FaeG expressed in L. lactis was up to approximately 10% of soluble whole-cell proteins, and recombinant FaeG (rFaeG) possessed good immunoreactivity by Western blot analysis. Oral immunization with recombinant L. lactis expressing FaeG induced F4-specific mucosal and systemic immune responses in the mice. In addition, high dose recombinant L. lactis or co-administration of high dose recombinant L. lactis with CTB enhanced the immune responses. These results suggested that L. lactis expressing FaeG was a promising candidate vaccine against ETEC.
