A New Proposal For Achieving Neuronal Regeneration

Medical News Today, Article Date: 20 Apr 2010 - 2:00 PDT
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...

HDAC-3 Inhibitors for Friedreich's Ataxia
We are currently developing inhibitors of histone deacetylase 3 (HDAC-3) for the treatment of inherited neurodegenerative diseases such as Friedreich's ataxia.  Preclinical studies have shown that specific HDAC-3 inhibitors increase production of the protein frataxin which may have the potential to arrest disease progression in patients with Friedreich's ataxia.  We plan to file an Investigational New Drug Application (IND) for a Phase 1 human clinical study of RG2833 in healthy volunteers this quarter.
