Escheriosome-mediated delivery of recombinant ribosomal L7/L12 protein confers protection against murine brucellosis.
Vaccine. 2007 Nov 14; 25(46):7873-84.V

Abstract

Brucellosis is an important zoonotic disease that causes abortion in cattle and undulant fever, arthritis, endocarditis and meningitis in human. In spite of the fact that immunization could be an efficient measure to control brucellosis, not a single ideal vaccine against this important disease has been developed so far. In order to develop an effective vaccine against Brucella abortus (B. abortus), various protective immunodominant gene/protein products of the pathogen have been studied in combination with different adjuvants. For example, recombinant ribosomal protein L7/L12 (rL7/L12) although an interesting T-cell antigen, normally failed to evoke protective immune response when used in free form. In the present study we have demonstrated that Escherischia coli (E. coli) lipid liposome (escheriosome)-mediated cytosolic delivery of recombinant rL7/L12 protein can elicit strong immunological responses in the Balb/c mice. In contrast, egg PC/Chol liposome entrapped rL7/L12, in a manner similar to its free form, was found to impart relatively poor immune response. Furthermore, escheriosome entrapped rL7/L12 protein elicited high IgG2a isotype response suggestive of its relevance in imparting protection against brucellosis in mice. Altogether the present study is a clear indicative of the possible use of escheriosome-based delivery of rL7/L12 protein to induce protective immune responses against experimental murine brucellosis.
