Main research interests
During the last years my research has focussed on the role of glia and progenitor cells in brain plasticity and repair, and on the implementation of cell replacement approaches in conjunction with training protocols to promote functional recovery in CNS diseases.
We believe that specific issues regarding glia and neural progenitors are particularly promising to both unveil new keys to the understanding of physiology, and accomplish therapeutic actions. We have revealed that a fundamental mechanisms oligodendrocyte progenitor self-maintenance is asymmetric cell division (Boda et al., Glia 2015), and provided among the first demonstrations of oligodendrocyte alterations and myelin abnormalities in Alzheimer disease (Behrendt et al., Glia 2013) and Autism models (Bertero et al., Brain 2018). We also have contributed to set up first in vitro rodent and human neural models of leukodystrophy (ADLD) to validate an allele-specific silencing therapeutic strategy (Giorgio et al., Brain, 2019).
As for astroglia, we have made important contributions on the development of astrocyte heterogeneity, and on how it differentially impacts on CNS functions is unknown. We addressed this topic by studying cerebellar morphogenesis, which lead to the first demonstration that an ontogenetic program, tightly regulated in space and time, determines astrocyte heterogeneity (Cerrato et al., PLoS Biol 2018). In parallel studies, we identified a functional requirement for SOX2 in postnatal Bergmann astrocyte differentiation and functions, of relevance for ataxia in mouse mutants, and in human patients (Cerrato et al., Glia 2018).
Further, we disclosed the first lineage contiguity between astrocytes and interneurons, demonstrating that bipotent astroglial-like progenitors give rise to both interneurons and white matter astrocytes (Parmigiani et al., J Neurosci 2015). One further key aspect of astrocyte heterogeneity is the link between adult parenchymal astrocytes and neural stem cells. We contributed to show that after excitotoxic lesion subsets of striatal astrocytes undergo a spontaneous neurogenic activation leading to the local generation of a large amount of neuroblasts (Nato et al., Development 2015). We are now exploring the underlying molecular mechanisms of both diversification of astrocyte types, and activation of neurogenic properties.
In respect to strategies to promote functional recovery in neurodegenerative models, we focused on a model for progressive ataxia caused by overactivation of autophagy leading to selective loss of Purkinje neurons. We showed that preventive transplantation does not alleviate the ataxic symptoms whereas preventive motor training increases Purkinje neuron survival with positive consequences on both cerebellar circuit alterations and the motor phenotype suggesting the use of preventive motor exercise in inherited ataxia to promote a delay in the progression of the disease (Fucà et al., Neurobiol Dis 2018). We translate this knowledge in parallel studies addressing the efficacy of hPSC-based cell replacement approaches in rodent models of Huntington’s disease.

SPACER: A single cell SPAtiotemporal transcriptomic atlas to unveil CERebellar development and function in mouse
SPACER , conceived by Prof. Annalisa Buffo and by the post doc Valentina Cerrato from the Physiopathology of neural stem cells group , is among the projects selected as winners of a highly competitive call of the European consortium EASI Genomics, in the frame of the Horizon 2020 program. In total, 143 research groups from 27 countries all over the world applied in response to this call, but only 33 projects were selected.

This work, which is the result of an annual multicenter pilot project supported by the Italian Multiple Sclerosis Foundation, has shown for the first time that exposure to PM has negative effects on the regenerative capacities of the nervous tissue, and in particular of myelin.
The European project NSC-Reconstruct - Novel Strategies for Cell-based Neural Reconstruction (Horizon 2020) has started today with a web-kick-off meeting. Prof. Annalisa Buffo (NICO - Department of Neuroscience of the University of Turin) leads work package 3, which is aimed at developing strategies for the repair of complex brain networks, such as those affected in Huntington's disease.
The overall goal of the project is to develop and optimize strategies based on effective neuronal replacement and circuit reconstruction to treat neurodegenerative diseases. NSC-Reconstruct is coordinated by Prof. Elena Cattaneo, University of Milan which brings together 13 partners including universities, research centers, industries and SMEs from six European countries.
