Full text not available from this repository. (Request a copy)A cDNA expression library representing the metacestode developmental stage of the tapeworm Echinococcus multilocularis was immunoscreened with monospecific antibodies affinity purified following differential immunoblot analysis. Using this procedure, a metacestode-specific clone was isolated representing a 14-3-3 gene of the parasite, which is present as a single copy in the parasite genome. The identity of this clone was demonstrated by cross-reactivity of the recombinant E. multilocularis 14-3-3 protein with antibodies raised against a heterologous 14-3-3 protein from Saccharomyces cerevisiae. In addition, expression of the E. multilocularis 14-3-3 gene in the mutant S. cerevisiae strain, DS9-22, resulted in complementation of the phenotypic deficiency of this strain, thus demonstrating the functionality of the respective gene product. By reverse transcription-polymerase chain reaction (RT-PCR) we showed that the E. multilocularis 14-3-3 protein is about 10-fold overexpressed in the metacestode stage compared with the expression level in the adult stage. Immunolocalization of the 14-3-3 protein in E. multilocularis metacestodes revealed its predominant presence in the germinal layer of the parasite. The results of this study, taken together with the current knowledge on the 14-3-3 protein family, suggest that this parasite molecule may contribute to the promotion of the progressive, potentially unlimited growth behaviour of the E. multilocularis metacestode within the host tissue.
