title: The possible role of tumor necrosis factor-alpha in diabetic polyneuropathy.
abstract: In this review, the authors provide evidences that imply the role of tumor necrosis factor-alpha (TNF-alpha) in the pathogenesis of diabetic complications, especially diabetic polyneuropathy. Under chronic hyperglycemia, endogenous TNF-alpha production is accelerated in microvascular and neural tissues, which may undergo an increased microvascular permeability, hypercoagulability, and nerve damage, thus initiating and promoting the development of characteristic lesions of diabetic microangiopathy and polyneuropathy. Enhanced TNF-alpha production may also promote atherosclerosis due to increased insulin resistance and the expression of adhesion molecules. Clinical application of specific agents that suppress production and/or activity of TNF-alpha may inhibit the development and exacerbation of chronic diabetic complications.
