Endothelial Dysfunction and Inflammation: Immunity in Rheumatoid Arthritis

Abstract EN

Inflammation, as a feature of rheumatoid arthritis (RA), leads to the activation of endothelial cells (ECs).

Activated ECs induce atherosclerosis through an increased expression of leukocyte adhesion molecules.

Endothelial dysfunction (ED) is recognized as a failure of endothelial repair mechanisms.

It is also an early preclinical marker of atherosclerosis and is commonly found in RA patients.

RA is now established as an independent cardiovascular risk factor, while mechanistic determinants of ED in RA are still poorly understood.

An expanding body of study has shown that EC at a site of RA is both active participant and regulator of inflammatory process.

Over the last decade, a role for endothelial dysfunction in RA associated with cardiovascular disease (CVD) has been hypothesized.

At the same time, several maintenance drugs targeting this phenomenon have been tested, which has promising results.

Assessment of endothelial function may be a useful tool to identify and monitor RA patients.
