From filopodia to synapses:the cell biology of neuronal wiring

Research summary

The main interest of the laboratory is to study the mechanisms involved in the formation and function of the synapse -the central element that allows the communication between neurons in brain- and in defining how these processes get wrong in brain diseases. A lot of recent evidence has indicated that several brain disorders, like epilepsy, schizophrenia and autism, but also Alzheimer’s disease, depend on a bad functioning of the synapse. In recent years we demonstrated that the capping protein Eps8 plays a crucial role in dendritic spine formation and plasticity and is reduced in brain of patients affected by autism. Moreover given inflammation and immune molecules have been recognized as important contributors to CNS injury we aim to define whether pentraxin3, which is a molecule of innate immunity whose expression is increased in epilepsy, may affect synaptic protein networks and function.
