[Contribution of endothelial cells to the immune processes. Influence of viral infections].

Contribution of endothelial cells to normal immune processes (circulation of leukocytes, immune diapedesis, presentation of antigens) as well as to pathology caused by viral diseases is described. Cytokine secretion and expression of adhesion molecules, particularly during viral infections are described. Permissiveness of endothelial cells to HIV infection is presented. Contribution of herpesviruses (CMV, HSV) to thrombosis and atherosclerosis is also considered.
