Abstract

In present study we investigated whether the serum concentration of tumour necrosis factor alpha (TNF-alpha) is associated with soluble adhesion molecules and vascular endothelial growth factor (VEGF) in rheumatoid arthritis (RA) patients. Serum levels of TNF-alpha, soluble intercellular adhesion molecule 1 (sICAM-1), soluble vascular cell adhesion molecule 1 (sVCAM-1), soluble E-selectin (sE-selectin) and VEGF were assessed by ELISA in 38 patients with RA. We demonstrated the TNF-alpha to correlate with sICAM-1 (p < 0.001), sVCAM-1 (p < 0.01) and VEGF (p < 0.01). No association was noticed between TNF-alpha and sE-selectin serum concentrations. Moreover, serum TNF-alpha, sICAM-1, sVCAM-1 and VEGF levels correlated with markers of RA activity such as the erythrocyte sedimentation rate, C reactive protein level and the number of swollen joints. Data presented in this report support the concept of the VEGF synthesis stimulation by TNF-alpha. Analysis of the serum TNF-alpha, sICAM-1, sVCAM-1 and VEGF levels may be useful in the prediction of the RA activity.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
