Under a variety of circumstances, melanin occurs in the dermal compartment of the skin, being mostly observed in cells that have been termed melanophages, some of which have been identified as dermal dendritic cells. We analysed changes in the expression and secretion pattern of cytokines by dendritic cells after the uptake of melanin from various sources. Dendritic cells were derived from human primary blood monocytes or from the human monocytic cell line THP-1. Melanin uptake increased the secretion of the chemokines MIP-1β (CCL4) and MCP-1 (CCL2). The higher MIP-1β secretion was accompanied by higher MIP-1β gene expression. Elevation of MIP-1β secretion was dependent on the uptake of melanin but could not be induced by the phagocytosis of latex beads, indicating that the phagocytic process itself was not sufficient to increase the secretion of this cytokine. The data thus show that the uptake of melanin changes the cytokine expression and secretion pattern of dendritic-like cells.
