Protective immunity against Legionnaires' disease in an A/J mouse model using a DNA vaccine composed of an outer membrane protein (29 kDa) and the PilE fusion protein
چکیده انگلیسی

In order to assess the protective effects of the DNA vaccine (pcDip/pilE) against Legionella pneumophila, the coding sequences of the 2 proteins were cloned into the pET32a(+) and pcDNA3.1(+) vectors. To provide an enhanced immunological response, the proteins were linked together. In this study, the A/J mouse model was used for examine the immunogenicity and protective efficacy of the DNA vaccines of pcDip, pcDpilE and pcDip/pilE. Our results showed that the total IgG titers were higher level increasing after the stimulation of pcDip/pilE than pcDip and pcDpilE immunization. The DNA vaccine (pcDip/pilE) can protect the A/J mouse against a higher dose (2 × 107L. pneumophila cells) of L. pneumonia compared to the other single-DNA vaccine in our study, and the ratio of the survival reached 100% in 10 days after the last DNA vaccine immunization. Our study indicates that these findings provide experimental evidence to support the claim that pcDip/pilE may be an efficient DNA vaccine against Legionella pneumophila.
