Taenia solium is an endemic cestode in Peru that infects pigs and humans. Two of its stages are: metacestode larva and adult worm. The larva lodges in soft tissues, forming a cyst that contains the invaginated scolex and neck of the parasite. The adult worm develops in the human intestine: a strobilus of proglottids that produce eggs is formed from the neck, becoming the disseminative stage of the parasite. The metamorphosis from the larval to the adult stage implies transcriptional changes that originate morphological modifications, mainly the evagination of the scolex and the generation of the strobilus. Both processes are critical in the development of the parasite, but the genes involved in these events have been scarcely explored in T. solium. Studies in other flatworms have identified transcriptional elements that regulate growth and regeneration. Among them is myoD, a transcription factor that induces and directs muscle cell differentiation. As orthologs are present in urochordates and echinoderms, myoD turns out to be a universal regulator of myogenesis in bilateral animals. In planarians, myoD induces the formation of longitudinal muscles, essential to initiate regeneration. In Hymenolepis microstoma, myoD has a higher expression in the neck and scolex of the adult stage. This suggests that the gene plays a role in the muscle development of both flatworms. However, the expression of myogenesis regulatory genes in T. solium has not been defined or characterized, despite the fact that myogenesis is an essential process in the neck for the continuous extension of the strobilus. Therefore, it is proposed to evaluate the expression of myoD in larvae and evaginated parasites in vitro and to use a silencing technique to confirm if this gene regulates the muscular development of the neck and, hence, participates in the metamorphosis from the larval to the adult stage of T. solium.
