Production of monocyte chemotactic and activating factor (MCAF) by human dermal fibroblasts in response to interleukin 1 or tumor necrosis factor

Abstract

Normal human dermal fibroblasts rapidly expressed (less than 30 min.) considerable mRNA for monocyte chemotactic and activating factor (MCAF) and released high levels of biological activity in response to interleukin 1 (IL 1) or tumor necrosis factor (TNF). In contrast, cultured normal human keratinocytes did not express MCAF mRNA when stimulated with IL 1 or TNF. These results suggest the important role of dermal fibroblasts, the predominant cells in dermal connective tissue, in the recruitment of monocytes during inflammation. This is the first report of the induction of MCAF by IL 1 or TNF in any cell type.
