title: The chemoattractant des-Arg74-C5a regulates the expression of its own receptor on a monocyte-like cell line.
abstract: The interaction of the chemoattractant des-Arg74-C5a (C5a des Arg) with its receptor on a human monocyte-like cell line, U-937, was examined. The data obtained suggest that C5a des Arg receptor expression is regulated by the extracellular concentration of C5a des Arg itself.
