CORTICAL LAYER II IMMATURE NEURONS ARE HETEROGENEOUS IN MAMMALS
The doublecortin-positive (DCX+) pre-natally generated neurons discovered in the layer II of the rodent piriform cortex are considered a reservoir of “immature” neurons in the adult brain. In some non-rodent species they extend into neocortex and in sheep also into subcortical regions. Hence, immature neurons might be more important in large-brained, long-living mammals. We assessed the occurrence, distribution and amount (linear density - cells/mm of layer II) of type 1 (small-bipolar) and type 2 (large-ramified) DCX+ cortical neurons at 4 comparable brain levels in 13 mammalian species endowed with different brain anatomy, lifespan, ecological niche. Sections were immunostained for cell proliferation (Ki-67, BrdU) and immaturity/maturity markers (PSA-NCAM, NeuN). All non-rodent species considered hosted DCX+ neurons in neocortex, with highly heterogeneous linear densities. By contrast, morphological and phenotypic features were rather constant: type 2 cells represented 10-20% of the total, mostly expressing NeuN, whereas 15-30% of DCX+ cells were also PSA-NCAM+. BrdU and Ki-67 antigen detection confirmed that all DCX+ neurons were non-newly generated/not proliferating. These results show that “immature” cortical neurons do represent a well preserved, yet, highly heterogeneous feature in mammals, especially considering rodent and non-rodent species.

Roberta Parolisi (Group Buffo)
Characterization of the action of extracellular vesicles derived from microglia on OPCs
EVs, being spontaneously produced by cells and containing a heterogeneous range of molecules, are emerging key mediators of intercellular communication.
We are studying the role of these vesicles released from alternatively activated microglia, on in vitro OPC proliferation and differentiation, and in vivo re-myelination after toxic demyelination

TTC3: a Down Syndrome gene involved in neuronal migration
Down syndrome (DS) is caused by trisomy of Human Chromosome 21 (HSA21). The clinical manifestations of DS vary in both penetrance and intensity among affected individuals, but the only hallmark common to all patients is intellectual disability (ID). DS-associated ID is the result of developmental brain abnormalities, leading to altered neuronal migration and connections within the cortex. One likely candidate for these phenotypes is TTC3, a HSA21 protein, whose expression is increased in cells derived from DS experimental models and from DS patients. Moreover, up-regulation of  TTC3 inhibits neuronal differentiation by modulating actin cytoskeleton.
In this last years, we are studying the effect of TTC3 over-dosage in cortical development, up-regulating the protein using in utero electroporation and we demonstrated that TTC3 levels are critical for correct neuronal positioning within the cortex. These data support the hypothesis that DS-cortical phenotypes can be ascribed to the increased dosage of TTC3.
