title: Adherence in combination with lipopolysaccharide, tumor necrosis factor or interleukin-1 beta potentiates the induction of monocyte-derived interleukin-8.
abstract: In this study we demonstrate that adherence of peripheral blood mononuclear cells (PBMC) to either plastic or extracellular matrix, such as collagen type I or fibronectin, is a significant stimulus for the induction of both interleukin-8 (IL-8) mRNA and antigen. In addition, adherence of PBMC in the presence of lipopolysaccharide, interleukin-1-beta, or tumor necrosis factor-alpha greatly enhances transcription/translation of IL-8 from these leukocytes. Our findings demonstrate that PBMC adherent to either plastic or physiological surfaces in combination with an inflammatory agonist is both a potent and efficacious signal for the expression and production of the neutrophil chemotactic/activating cytokine, IL-8.
