The protein quality control system in motoneuron diseases
Dipartimento di Scienze Farmacologiche e Biomolecolari Università di Milano
Motor neuron diseases, like spinobulbar muscular atrophy (SBMA) and amyotrophic lateral sclerosis (ALS) are characterized by the presence of inclusions or aggregates of proteinaceous materials. This is due to the generation of aberrant conformations (misfolding) of the proteins responsible for the diseases.
In neuronal cells, the protein quality control (PQC) system may be insufficient to correctly remove the misfolded proteins.
The PQC system requires the activities of efficient chaperones and of the degradative systems ubiquitin-proteasome (UPS) and autophagy. Our approaches are to better characterize the role of the PQC in motoneuron diseases and to find possible ways to boost the PQC activity in order to prevent the damages induced by misfolded proteins to neurons.

I nostri giovani ricercatori aggiornano i colleghi sulle loro ricerche. Appuntamento ogni due venerdì.
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.
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.
