Abstract

Cell-to-cell interactions in the immune system are mediated by several different families of receptors on the cell surface, known as adhesion molecules. These adhesion molecules influence many diverse processes including growth, differentiation, migration, and killer-target cell interactions. To fulfill these effects, the density and the expression of these glycoproteins varies in relation to the cellular state of activation. The expression of these adhesion molecules is shown to be modulated by interferon gamma (IFN-γ), tumor necrosis factor alpha (TNF-α), interleukin (IL) 1,4, and 7 [1–3]. IL-2 has been shown to induce an upregulation of some adhesion molecules in vitro [4]. However, it remains unclarified, whether this modulation is mediated by IL-2 itself or by release of secondary cytokines. Additional, no data are available so far concerning the modulation of adhesion molecules after immunotherapy with IL-2. In this study we focussed our interest on the expression of adhesion molecules on peripheral blood lymphocytes (PBL) and the serum levels of soluble CD54 (ICAM-1) in vivo after immunotherapy with IL-2.
