Allele-specific siRNAs as therapeutic option for ADLD: in vitro pre-clinical validation on unique human experimental models
2020-2022 | ELA International, Luxembourg
Research network: E. Giorgio and A. Brusco (University of Torino), S Goldman (University of Rochester, USA).
In this project we will generate two innovative glial in vitro disease models based on induced pluripotent stem cells (iPSC) derived from ADLD (Autosomal Dominant leukodystrophy with autonomic disease) patients that will allow validating our therapeutic strategy based on Allele Specific Silencing. Our project is intended to pave the way towards a therapy for ADLD and also establish distinctive human ADLD-relevant models and therapeutic approaches that may have great importance for future studies non only on ADLD but also on the physiopathology and therapy of other leukodystrophies and genetic diseases.
Driving microglia metabolism toward remyelination and restoration of brain damage in MS

Research network: coordinator Claudia Verderio, Neuroscience Institute (IN) of CNR, Marta Fumagalli, University of Milan, Pierre Gressens, Inserm, Paris; Peter Cameliet, Vesalius Research CentreLeuven; Antonio Uccelli, University of Genoa
This project aims at defining the metabolic signatures that define a pro-regenerative microglial phenotype as expressed by extracellular-vescicle-mediated enhancement of remyelination by rodent oligodendrocyte progenitor cells. The ultimate goal of this research is to modulate the phenotype of human microglia so that microglia can foster myelin repair. We contribute our specific expertise in oligodendrocyte progenitors and mouse models of Multiple Sclerosis and examine how delivery of microglia-derived extracellular vescicle to the brain of mouse models affects oligodendrocyte progenitors and remyelination in vivo.
Characterization of a novel microRNA involved in myelination: a new potential pathogenetic mechanisms in multiple sclerosis
2015-2017 | Cariplo Foundation - Biomedical Research conducted by Young Researchers
Enrica Boda, head of reseach unit; Davide Lecca, University of Milan, coordinator
This project aims at elucidating the role of a novel family of miRNAs in the regulation of oligodendroglial differentiation and in the pathogenesis of Multiple Sclerosis.
Influence of maternal behaviour on the expression of brain plasticity brakes: a role in the susceptibility to anxiety?
2015-2017 | Research Project, University of Turin - Compagnia di San Paolo
Daniela Carulli co-PI with Carola Eva, NICO
This project aims at elucidating whether maternal care affects chemical/physical features of perineuronal nets in the limbic system thereby influencing neuronal communication within specific networks and, in turn, anxiety in the adult.
Neurostemcellrepair - European stem cell consortium for neural cell replacement, reprogramming and functional brain repair

This project aims at developing new strategies for stem cell therapies in Hungtington and Parkinson diseases, including acquisition of specific neuronal identities and functional integration in the recipient brain. We contribute our expertise in rodent models of Hungtington disease, and analyse how specific training activities can ameliorate differentiation and integration of grafted cells.

Determinants of neuronal degeneration in Ataxia-Telangiectasia
2014-2017 | Telethon Foundation
Project PIs: Domenico Delia, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, and Lorenzo Magrassi, Dipartimento di Scienze Clinico-Chirurgiche, Diagnostiche e Pediatriche, University of Pavia. Annalisa Buffo and Giulia Nato take part in the project as external collaborators.
This project aims at unveiling the functional defects that determine malfunctioning and neurodegeneration in the cerebellum of patients suffering from Ataxia-Telangiectasia. To reach this goal we study how neuronal cells obtained from the fibroblasts of patients and healthy controls mature, survive and function.

Targeting oligodendrocyte progenitor cell division mode to improve myelin repair in the aging CNS
2014-2015 | Fondazione Umberto Veronesi - Postdoctoral Fellowship Program, Enrica Boda
Myelin is a lipid-rich ensheathment produced by specialized cells called oligodendrocytes, that enwrap neuronal axons and allow the fast conduction of nervous signals. Myelin damage causes very serious pathologies characterized by motor and cognitive symptoms. In the human brain, aging is associated with the loss of myelin, reduced oligodendrocyte production and delayed remyelination in case of insults or pathology.
This is at least in part due to molecular alterations in oligodendrocyte progenitors, that affect their division modality and regenerative/reparative functions. The identification of these molecular mechanisms is highly relevant for the comprehension of the OPC biology and age-related functional decline, and can set the basis for new therapeutical approaches aimed at improving adult oligodendrogenesis and eventually ameliorate myelin integrity and repair at old ages.
This knowledge may be also applied to the study and treatment of human neurodegenerative diseases.
