Abstract

In this study, we employed Taenia solium mRNA extracted from a tapeworm of Venezuelan origin to clone express and test the recombinant protein of the T. solium homologue of the 18-kDa oncospheral adhesion molecule of Taenia saginata (HP6-Tsag/TSA18). We first confirm the conserved nature of the sequence of the T. solium homologue (TSOL18/HP6-Tsol) and demonstrate that the recombinant protein, which, as with its T. saginata homologue, is characterised by a fibronectin type III homology region, functions as an adhesion molecule. This emphasises the possible importance of TSOL18/HP6-Tsol in tissue invasion, thus providing a rational explanation for its efficacy as a vaccine. As protection against Taenia spp., oncospheres is antibody mediated, logically, therefore, TSOL18/HP6-Tsol may also serve as a diagnostic antigen, as is indeed the case for recombinant HP6-Tsag/TSA18.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
