Linking fatty acid metabolism to peripheral neuropathy
Nico Mitro
Department of Pharmacological and Biomolecular Sciences, University of Milan
Myelin is a membrane characterized by high lipid content to facilitate impulse propagation. Changes in myelin fatty acid (FA) composition have been associated with peripheral neuropathy, but the specific role of peripheral nerve FA synthesis in myelin formation and function is poorly understood.
We have found that mice lacking sterol regulatory element-binding factor-1c (Srebf1c) have blunted peripheral nerve FA synthesis that results in development of peripheral neuropathy. Srebf1c null mice develop Remak bundle alterations and hypermyelination of small caliber fibers that impair nerve function.
Peripheral nerves lacking Srebf1c show decreased FA synthesis and glycolytic flux, but increased FA catabolism and mitochondrial function. These metabolic alterations are the result of local accumulation of two endogenous peroxisome proliferator-activated receptor-α (Pparα) ligands, 1-palmitoyl-2-oleyl-sn-glycerol-3-phosphatidylcholine and 1-stearoyl-2-oleyl-sn-glycerol-3-phosphatidylcholine. Treatment with a Pparα antagonist rescues the neuropathy of Srebf1c null mice. These findings reveal the importance of peripheral nerve FA synthesis to sustain myelin structure and function.

GLIAL CELLS-NEURON CROSSTALK IN CNS HEALTH AND DISEASE

University of Turin, Italy  
The Workshop is aimed at PhD students and young Postdocs with the goal to promote a thorough understanding of the functions of glial cells in health and disease. The program includes lectures on the newest conceptual advancements and methodological approaches in the study of glial cells in synaptic functions, development and CNS diseases.

Deadline for registration: December 23, 2019.

Sportello LESIONI SPINALI

Paziente tetraplegico operato al CTO di Torino torna a usare le mani

Una notizia che abbiamo letto tutti di recente sui giornali. Noi del NICO abbiamo la fortuna di collaborare da anni con il dott. Bruno Battiston e il prof. Diego Garbossa - i chirurghi che hanno svolto l'operazione - e ci siamo fatti spiegare bene in cosa consiste l’intervento, quale era la situazione del paziente e quali saranno i possibili risultati. 
Tutto questo al di là delle semplificazioni e dei titoli roboanti dei giornali, comprensibilmente utilizzati per attirare l’attenzione dei lettori.
