Is diabetic neuropathy associated with activation of the TNF-alpha system in subjects with type 1 diabetes mellitus?
The activity of the TNF-alpha system is increased in subjects with type 1 diabetes mellitus and diabetic neuropathy, regardless of their glycaemic control and cardiovascular risk factors associated with insulin resistance. These results suggest that TNF-alpha may play a pathogenic role in the development of diabetic neuropathy.
These results provide direct evidence that CCR2 expressed by leukocytes plays a critical role in the initiation of early atherosclerosis and that pharmacological intervention in CCR2 function represents an attractive target to inhibit atherogenesis.
