Abstract
An NC-1 mimotope from Taenia solium cysticerci can help identify patients with neurocysticercosis through immunoassay. After chemical synthesis, an NC-1 peptide was coupled to bovine serum albumin (NC-1/BSA) for used as an immunogen in murine Taenia crassiceps cysticercosis, which is an experimental model of cysticercosis caused by T. solium. NC-1/BSA immunisation decreased parasitaemia by inducing 74% protection compared to the 77% protection obtained with T. crassiceps crude antigen. The influence of immunisation was also observed on the size and stage of development of the parasite. Antibodies from NC-1/BSA-immunised mice recognised proteins from the tegument and from the buddings, and intense immunostaining was observed in the final stage of the metacestode. The capacity of NC-1/BSA to induce protective antibodies which are reactive to proteins from the tegument of the metacestode suggests that this mimotope is a potential candidate for a vaccine against human and animal cysticercosis.
