The timing and proper formation of the neocortex is genetically programmed during development and can be profoundly altered by a number of abnormal genes that control regionalization, proliferation, differentiation and cell migration. In addition, thalamocortical inputs are important in shaping area-specific functional properties, possibly through activity-dependent mechanisms.   

The lab is interested in understanding how regional identity, once established at progenitors level, is maintained in differentiated cortical pyramidal neurons during corticogenesis, and whether specific neuronal sub-populations or cortical circuits are peculiar of distinct functional neocortical areas. We are interested in a family of transcription factors, the COUP-TF family, which are involved in regional and cell-type specification of the dorsal and ventral telencephalon during development. Our recent data illustrate that COUP-TFI regulates different phases of cortical development in generating specific cell types in each brain region according to precise time schedules and to its region- and temporal-specific expression gradient.

During my presentation, I will do an overview on how transcription factors, including the COUP-TFs, can control the early and late organization of the cerebral cortex by acting on regionalisation, cell migration, connectivity, cell-type specification and neuronal activity. I will also illustrate some molecular and cellular mechanisms underlying cell-type specificity and morphological maturation across cortical areas, with particular emphasis on layer V projection neurons. Finally, I will speculate on how spontaneous neural activity could participate in setting up area-dependent neuronal circuits in the immature neocortex.

Torino - 10th International Meeting STEROIDS and NERVOUS SYSTEM

Since 2001, this meeting represented an important event for basic and clinical researchers working on this emerging scientific topic. We will address state-of-the-art approaches in the field of steroids and nervous system, including behavior, epigenetics, genomic and non-genomic actions, the vitamin D, neurodegenerative and psychiatric disorders, and the interference among endocrine disruptors and steroid signaling.

Ricerca

Neurone o astrocita? Scoperto il gene che guida le staminali adulte nella scelta del loro destino.

Il gene COUP-TFI controlla che le staminali producano la giusta quantità di nuovi neuroni o astrociti. Un eccesso dei secondi è la conseguenza di processi infiammatori associati a patologie tra cui l’Alzheimer. La scoperta del team guidato da Silvia De Marchis, del nostro gruppo di Neurogenesi adulta.
