The group is currently working on several research projects aimed at understanding the molecular properties of ion channels in cell signaling and their regulation by neurotransmitters, hormones and drugs. In particular, the group is interested on the functional role that voltage-gated calcium channels play in regulating cell firing, neurotransmitter release (exocytosis) and vesicle retrieval (endocytosis) in neuroendocrine cells and brain neurons in control and pathological conditions. In collaboration with the Universiy of Ulm (Dr. A. Pasquarelli) and to the Department of Physics (University of Torino) a new line of research is also dedicated to the use of diamond-based microelectrode arrays (MEAs) for recording electrochemical signals from central neurons, adrenal chromaffin cells and intact sino-atrial node tissues to be used for large scale drug-screening.

We are currently working of the effect of calcium dyshomehostasis on neuronal function during onset of Autism spectrum disorders (ASD) and neurodegenerative diseases like Alzheimer's (AD) and Parkinson diseases (PD). A consolidated hallmark of AD onset and possibly other neurodegenerative diseases is represented by the uncontrolled increase of intracellular calcium concentration ([Ca2+]i) responsible in turn for the onset of calcium dysregulation phenomena and related excitable and synaptic dysfunctions. It has been recently shown in AD mouse models that accumulation of Abeta oligomers prevents the proper interaction between RyRs and intracellular stabilizer proteins known as calstabins (Fig.1), not allowing the complete closure of RyRs which assume a leaky conformational state and generate a continuous slow release and accumulation of calcium into the cytoplasm.


Another research project is aimed at evaluating the effects of exogenous oligomeric alpha-synuclein on cultured midbrain dopaminergic neurons. In particular, we are focused on monitoring the effects at early stages of network development and on mature neurons.





The research laboratories of the group are fully equipped for running experiments of classical and modern electrophysiology. We are currently able to record whole-cell and single channel membrane currents, action potential firing, secretory events associated to the fusion of secretory vesicles from central and sensory neurons and neuroendocrine cells. To this purpose we use patch-clamp amplifiers; puller and micro-forges for the fabrication of glass microelectrodes; micro-movements and inverted microscopes for the electrode positioning). Recently, through funds received from the N.I.S. ( and the Regione Piemonte, the group has acquired two complete 8x8 MEA ( recording systems for monitoring the spontaneous activity of brain neuron networks and excitable tissues (cardiac sino-atrial node; adrenal chromaffin cells, pancreatic β-cells). A Leica fluorescence microscope acquired with funds of the Cavalieri-Ottelenghi foundation ( is also available for fast and high-resolution cell calcium imaging. One electrophysiological set-up equipped with a confocal microscope for patch clamp recordings form brain slices recording is also available.


The group runs the tissue culture facilities of the DSTF. The service is fully equipped with CO2/O2 incubators for hypoxia, microscopes, laminar flow hoods, thermostatic baths, etc… for isolating and maintaining several acute and long-term cell type cultures (hippocampal neurons, adrenal chromaffin cells, dopaminergic neurons, dorsal root ganglion neurons) and clonal cell lines.
