The research conducted by the DESYNE team is in the field of comparative neuroendocrinology. They aim to understand the origin (developmental and evolutionary) and the role of neuroendocrine systems.

Activities in detail

Our work revolves around 2 main axes:

  • Evolution of multigene families of neuropeptides
  • Roles of the peptides of the urotensin II and somatostatin families

They use the zebrafish and, to a lesser extent, the xenopus, as models

Our team is also involved in a collaborative project with the unit STRING (UMR7196) entittled : Repair of double-strand breaks in DNA during embryonic development of zebrafish
