摘要

The specific response of murine Schwann cells IMS32 to acute and chronic hyperglycemia conditions was evaluated. The pathophysiological alterations were studied to deepening the role of Schwann cells in diabetes-related neurotoxicity and to assess a model to screen new protective molecules. IMS32 were incubated with 30 and 56 mM glucose for 48 h and 7 and 14 days, and markers of oxidative stress, apoptosis, and polyol pathway were evaluated. High glucose induced O-2-production and lipid peroxidation at all time point whereas Caspase 3 activity was induced only after 14 days. Aldose reductase activity and expression were significantly increased after 48 h and 14 days, respectively. Our results describe the response of Schwann cells to high glucose conditions and suggest the use of IMS32 for the screening of protective molecules in diabetes-induced neuropathy.
