This article is a continuation of the review on the issue of the interaction between the endothelium and numerous biologically active substances, secreted by endotheliocytes and their environment--the so called signal molecules--in the most prevalent cardiovascular pathology in the elderly. For example tumor necrosis factor plays a pathogenetic role as an immunomodulator, possesses anti-inflammatory and pro-atherogenic properties, provokes endothelial dysfunction, and stimulates the expression of other pro-inflammatory cytokines. Other signal molecules are described as well. The article also presents data from studies directed towards the perfection of atherosclerosis therapy via affecting signal molecules: depression of the expression of interleukins and their receptors, inhibition of atherogenic interleukins, neutralization of pro-inflammatory interleukins, and introduction of interleukin receptor antagonists.
