Cell biology of the synapse: deciphering the role of genetic and environmental factors in synapse function and dysfunction


Research summary

The main interest of the laboratory is the study of 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. Synapses are fundamental brain structures that mediate information transfer between nerve cells. Signal transmission and information processing at synapses control all body functions and all aspects of cognition, including attention, perception, learning, decision making, as well as mood and affect. Since several years it has been recognized that many psychiatric and neurodegenerative disorders are synaptopathies, i.e. pathological conditions where the molecular and cellular pathways operating at the synapse are dysregulated. Recent contributions of the lab to the field of synaptopathies and neuroinflammation include the identification of the role of the SNARE protein SNAP-25 (involved in ADHD and schizophrenia) in the modulation of calcium channels and network excitability and the demonstration that reduced protein levels impact cognitive processes, altering short term plasticity and spine morphology.

More recently, evidence was provided that inflammation can speculatively modify the risk and/or severity of a variety of brain diseases. Although several molecules involved in inflammatory processes have been found to regulate specific neuronal processes, the processes by which inflammation cascades impact synapse formation and function, contributing to the onset of a brain disease is not defined. The research activity of the Laboratory aims at understanding the molecular mechanisms at the basis of synapse dysfunctions in neurodegenerative and psychiatric diseases and at defining whether key immune molecules impact this process, in order to identify new targets suitable for therapeutic interventions.
