[Role of tumor necrosis factor alpha in atherosclerosis].
We describe tumour necrosis factor alpha and its role in the development of the atherosclerotic lesion, and detail the effects of this cytokine upon vascular endothelial cells under normal and high risk conditions. We propose that TNF-alpha performs a central role in the progression of the lesion since, once the endothelial cell feedback regulatory mechanisms are altered, there is an increase in the microenvironment TNF-alpha concentration, which together with some of the already well known risk factors, generates an environment that favours and perpetuates the development of the atheromatous lesion.
