Abstract
The macrophage cell line, RAW264.10, synthesizes and secretes plasminogen activator. Production of this enzyme is inhibited by low concentrations of glucocorticoids and increased by phorbol myristate acetate. It is proposed that this line could be a suitable model for the regulation of enzyme synthesis by mouse peritoneal macrophages.
