| Popis | Apicomplexa represent one of the most successful and diverse group of unicellular parasites exhibiting unique adaptations to their life style. Their motile invasive zoites use a unique conserved form of actin-based gliding motility. Since cytoskeletal elements play an important role in various life processes of Apicomplexa, they represent a potential target for chemotherapeutic intervention. Our intent is to investigate whether the glideosome concept, proposed in Toxoplasma, could be applied also to basal apicomplexan lineages. We focus on deep-branching groups, especially gregarines and protococcidians, restricted to invertebrates. These parasites exhibit diverse modes of locomotion depending on their cell architecture and surrounding environment, e.g. slow peristalsis-like movements observed in urosporidians and protococcidia, gliding in eugregarines equipped with well-developed epicytic folds, and finally active bending, rolling or coiling known from marine archigregarines that probably evolved from hypertrophic zoite and thus retained subpellicular microtubules.
