Abstract

L'invention concerne l'utilisation d'agonistes de l'adrénocepteur β pour rétablir et/ou maintenir la fonction de cellules partiellement ou entièrement endommagées/dégénérées du système nerveux central et/ou d'autres cellules nerveuses. L'utilisation d'agonistes de l'adrénocepteur β permet d'activer des astrocytes et de lancer des processus endogènes de neuroprotection, ce qui permet de réduire l'altération ou la destruction de cellules nerveuses, voire dans certains cas même les empêcher.
