Abstract T cells are known to interact cooperatively with monocytes to produce Colony-Stimulating Factors (CSF), although T cell-mediated signals leading to CSF secretion by monocytes are not completely understood. We have made use of Northern blot hybridization and specific bioassays to study the effects of the T cell product interleukin-4 (IL-4) on monocyte CSF expression. The results suggest a previously unrecognized role of IL-4 as a CSF inducer since exposure of monocytes to IL-4 resulted in accumulation of transcripts for granulocyte-CSF (G-CSF) and macrophage-CSF (M-CSF). Consequently, IL-4-activated monocytes released factors in their culture supernatants biologically and antigenically indistinguishable from G- and M-CSF.
