C. Contributions to Science

1. Functional properties and modulation of neuronal nicotinic receptors (nAChRs) in homeostasis and disease. As a PhD student, and as a Pot Doc, using patch clamp and confocal calcium imaging, I studied the expression and the functional properties of nAChRs in native cells and in heterologous expression systems [12 papers]. I developed a novel class of CGRP-derived peptides with facilitating action on nAChRs (Eur. patent app. N° PCT/IT01/00477). These studies allowed to correlate basal mechanisms of excitatory cholinergic transmission with clinical aspects in amyotrophic lateral sclerosis [4 papers] and Duchenne s muscular dystrophy (DMD) [2 papers].

2. Functional properties of GABA receptors in homeostasis and disease. Then, during my second Post Doc I moved to the study of GABAA receptors, characterizing functional properties of GABAA receptors in human temporal lobe epilepsy. I developed an innovative approach to record single neuron and glial cells in slices from surgically resected human cerebral tissue [4 papers]. I also studied the mechanism of tumor associated epilepsy, demonstrating that glutamate, released by glioma cells, depolarizes neuronal Cl- equilibrium causing GABA mediated hyperexcitability [2 papers].

3. Functional role of microglia/neuron interaction in physiological and pathological conditions. As a researcher I focused on the impact of neuroinflammation in brain pathologies with major interest on the role played by microglia cells on neuron/microglial crosstalk with multidisciplinary approaches [9 papers]. I focused on the morphological and functional characterization of microglia cells in physiological and pathological conditions looking at the ability of microglia cells of monitoring tissue homeostasis and rearranging processes towards an injury [3 papers].

4. Identification of neurodegenerative diseases biomarkers in the retina. As an independent investigator, I am now focusing on the morphological and functional characterization of microglia in physiological and pathological conditions in brain and retina of patients and models of neurodegenerative diseases. I m working on the possibility to use the eye as a window on the brain for the early diagnosis and monitoring of Alzheimer s and other neurodegenerative diseases characterized by the presence of misfolded protein aggregates. These observations defined novel biomarkers in the AD retina, and supported an emerging view using the eye as a window to monitor brain pathologies.

5. Generation and functional characterization of novel 3D neuronal constructs. I m currently working on the development and functional characterization of 3D in vitro models of human tissues derived from reprogrammed human cells.. We plan to generate novel 3D models of the human nervous system, including the brain cortex and the retina, to assess whether they can be used for drug testing and for developing new diagnostic tools.
