Potential drug to annul ADAM-17 protein activity needed

Over the past four years, in the installations of the Faculty of Medicine, University of Cadiz, a group of researchers, headed by Doctor Carmen Estrada, has been studying neurogenesis - the process of forming new neurons from mother cells - in the adult mammal brain. The purpose of this research project is to contribute to the knowledge of this process with the object of finding some additional mechanism that would facilitate the treatment of pathologies of the central nervous system (CNS) that are suffered in consequence of neuronal death.
