Attività

Siamo interessati ai meccanismi che regolano lo sviluppo e la plasticità delle sinapsi nel sistema nervoso centrale. Il gruppo studia in particolare le sinapsi GABAergiche, che sono le principali sinapsi inibitorie a livello encefalico. Utilizzando animali geneticamente modificati e tecniche di “imaging” ad alta risoluzione, analizziamo il ruolo dei recettori del GABA, di molecole di adesione e di proteine strutturali nella sinaptogenesi. In parallelo, studiamo difetti sinaptici in modelli murini di patologie neurologiche, tra cui la sclerosi multipla (in collaborazione con Annalisa Buffo), la sindrome di Rett (in collaborazione con Maurizio Giustetto) e le distrofie muscolari.

Settore ERC del gruppo:
LS5_1 - Neuroanatomy and neurophysiology
LS5_2 - Molecular and cellular neuroscience
LS5_3 - Neurochemistry and neuropharmacology
