Chemokines are typically found as products of acute stimulation of host defence cells. In contrast, the mouse CC chemokine C10 was previously shown to be a delayed, stably induced product of macrophages treated with interleukin 3 (IL-3), IL-4 or GM-CSF. We investigated the possibility that C10 is differentially regulated by cytokines associated with Th1 and Th2 cells. Northern blot analysis of bone marrow-derived macrophages showed that, in addition to IL-4, the Th2-specific cytokines IL-10 and IL-13 upregulated C10 over a 48-h period in a dose-dependent manner. In contrast, MIP-1α and MCP-1/JE were induced by IL-3 or GM-CSF at 48 h and this induction was inhibited by IL-4. Interferon γ, a Th1-specific product, abolished the induction of C10 mRNA and protein by either IL-3 or granulocyte-macrophage colony-stimulating factor (GM-CSF) in either bone marrow-derived or peritoneal macrophages. The inhibition of C10 production by interferon γ was not NO dependent. Finally the GM-CSF-mediated induction of C10 in peritoneal macrophages was eliminated when these cells presented antigen to established T cells of Th1 phenotype. The findings are consistent with a potential role for C10 in the modulation of immune reactions of Th2 type. (C) 2000 Academic Press.
