Research Statement:
All Arthropods possess a hard exoskeleton that protects and supports their bodies. However, this evolutionary successful structure presents a several challenge for their continuous growing. Then to growth, Arthropods must shed their exoskeleton (ecdysis), a process known as the molt. The ecdysis is precisely controlled and triggered by the action of a set of neuropeptide hormones. Therefore, the ecdysis of Arthropods is an excellent model to understand the mechanisms of control and action of neuropeptides over behavior and development of animals. Previously, I have been investigated the ecdysis and shell-hardening process in crustaceans. Now, taking advantage of the powerful Drosophila model, I am moving further to understand the role of some neuropeptides in the ecdysis behavior of insects.
