The endothelium is now considered a real endocrine-paracrine organ, important notonly as a structural barrier between the circulation and surrounding tissue, but also because it plays an essential role for local hemodynamics, releasingsubstances that modulate the vascular calibre and blood cell activation. Here,after a brief but detailed analysis of the importance of the endothelium in vascular homeostasis, in the control of coagulation and in the relations with the different blood cells, we will explain the concept of endothelial dysfunction (altered NO release) and activation (amplified adhesion molecule expression) in inflammatory, connective tissue and post-trasplantation diseases. Furthermore, this review will focus on the activity of prostacyclin and synthetic analogs, especially their ability to interact with the vasodilatation system and their role in modulating cell interaction by surface adhesion molecule expression,cytokines and growth factors release as well as gene transcription factors.Finally, we will consider the therapeutic role of prostacyclin analogs in theprevention and treatment of connective tissue diseases.

Abstract

The endothelium is now considered a real endocrine-paracrine organ, important notonly as a structural barrier between the circulation and surrounding tissue, but also because it plays an essential role for local hemodynamics, releasingsubstances that modulate the vascular calibre and blood cell activation. Here,after a brief but detailed analysis of the importance of the endothelium in vascular homeostasis, in the control of coagulation and in the relations with the different blood cells, we will explain the concept of endothelial dysfunction (altered NO release) and activation (amplified adhesion molecule expression) in inflammatory, connective tissue and post-trasplantation diseases. Furthermore, this review will focus on the activity of prostacyclin and synthetic analogs, especially their ability to interact with the vasodilatation system and their role in modulating cell interaction by surface adhesion molecule expression,cytokines and growth factors release as well as gene transcription factors.Finally, we will consider the therapeutic role of prostacyclin analogs in theprevention and treatment of connective tissue diseases.
