Abstract The effect of recombinant human interleukin-4 (IL-4) on a granulocyte colony-stimulating factor (G-CSF)-dependent human myeloblastic leukemic cell line, OCI-AML1a, was investigated. IL-4 suppressed the clonogenic cell growth in methylcellulose culture, inhibited the uptake of 3H thymidine in a dose-dependent manner at 5 to 100 U/mL, and consequently suppressed the growth of clonogenic cells in short- and long-term suspension cultures. In addition, IL-4 markedly increased the number of adherent cells. These adherent cells were alpha-naphthyl-butyrate (alpha-NB) esterase-positive and showed macrophage-like appearance, increased expression of CD14, CD11b, CD23, and Ia, and significantly decreased clonogenicity. On the other hand, nonadherent cells growing in suspension showed only slight increase in proportion of alpha-NB esterase-positive or monocyte/macrophage-like cells and increased CD23 expression by an addition of IL-4. The clonogenicity of the nonadherent cells was not significantly influenced by IL-4. By addition of the media conditioned by OCI-AML1a cells in the presence of IL-4, the clonogenic cells growth of OCIAML1a cells was suppressed and adherent cells were markedly increased. The suppressive and differentiative effects on OCI/AML1a cells of the conditioned media and IL-4 itself were almost completely abolished by anti-IL-4 antibody. Furthermore, the neutralizing antibodies against transforming growth factor-beta 2 (TGF-beta 2), tumor necrosis factor-alpha (TNF-alpha), or IL-6 did not influence the effect of recombinant IL-4. Taken together, IL-4 was shown to suppress the growth and induce differentiation toward adherent macrophage-like cells of the G-CSF-dependent myeloblastic cell line. The effect of IL-4 may be direct, and not secondary via inducing production of other cytokines such as TGF-beta, TNF-alpha, or IL-6 by leukemic cells.

We have established a new nonlymphoid leukemic cell ine from a patient with myelodysplastic syndrome (MDS), which progressed to overt leukemia. The parental cell line and a subline derived from this line have absolute dependency on several cytokines for their long-term survival and growth. The parental line designated F-36P requires granulocyte-macrophage colony-stimulating factor (GM-CSF) or interleukin-3 (IL-3) for continuous growth, while a subline designated F-36E can be maintained in the presence of erythropoietin (Epo) alone. When these cytokines are depleted, both the parental and the subline cells die within several days, even in medium supplemented with fetal calf serum (FCS). F-36E, maintained in the presence of Epo, constitutively synthesizes hemoglobin at a significant level. F-36P, which is usually maintained in the presence of GM-CSF or IL-3, can be induced to synthesize hemoglobin when GM-CSF or IL-3 is substituted by Epo. The surface marker profile shows that the F-36P cells are positive for the leukocyte common antigen (CD45) and some common multilineage markers such as CD13, CD33, and CD34, and negative for T- and B-cell antigens and mature myelomonocytic antigens. However, some monoclonal antibodies recognizing erythroid and platelet glycoproteins react with these cells. Thus, this cell line has a multilineage phenotype, suggesting that the transformation event occurred in a multipotent stem cell. It is also evident that the F-36 cells can be induced to differentiate into the erythroid lineage in the presence of Epo. This, to our knowledge, is the first description of a human leukemic cell line that can be stimulated to synthesize hemoglobin by Epo.

Several laboratories have developed culture systems that allow the generation of large numbers of human dendritic cells (DC) from monocytes using granulocyte-macrophage colony stimulating factor (GM-CSF), and interleukin-4 (IL-4). In this work we provided evidence that GM-CSF (100 ng/ml) in combination with a low concentration of IL-4 (5 ng/ml) was efficient in the generation of immature, non-adherent, monocyte-derived DC as the same concentration of GM-CSF, and ten times higher concentration of IL-4 (50 ng/ml). This conclusion was based on the similar phenotype profile of DC such as the expression of CD1a, CD80, CD86, and HLA-DR, down-regulation of CD14, and the absence of CD83, as well as on their similar allostimulatory activity for T cells. A higher number of cells remained adherent in cultures with lower concentrations of IL-4 than in cultures with higher concentrations of the cytokine. However, most of these adherent cells down-regulated CD14 and stimulated the proliferation of alloreactive T cells. In contrast adherent cells cultivated with GM-CSF alone were predominantly macrophages as judged by the expression of CD14 and the inefficiency to stimulate alloreactive T cells. DC generated in the presence of lower concentrations of IL-4 had higher proapoptotic potential for the Jurkat cell line than DC differentiated with higher concentrations of IL-4, suggesting their stronger cytotoxic, anti-tumor effect.

Granzyme B and perforin are cytoplasmic granule-associated proteins used by cytotoxic T lymphocytes and natural killer (NK) cells to kill their targets. However, granzyme B gene expression has also been detected in a non-cytotoxic hematopoietic murine multipotent stem cell line, FDCP-Mix. The objective of the present study was to investigate whether granzyme B and perforin could be expressed in human hematopoietic CD34+ cells and if present, discover what their physiologic relevance could be. The primitive CD34+ human cell line KG1a was investigated first and was found to express granzyme B and perforin. Highly purified hematopoietic stem/progenitor cells were then selected using the CD34 surface antigen as marker. Steady-state bone marrow (BM) CD34+ cells did not contain these proteins. Peripheral blood (PB) CD34+ cells, which had been induced to circulate, were also analyzed. After chemotherapy (CT) and granulocyte colony-stimulating factor (G-CSF) treatment, CD34+ cells strongly expressed mRNAs and proteins of granzyme B and perforin. In contrast, CD34+ cells mobilized by G-CSF alone were negative. Western blot analysis further showed that granzyme B and perforin proteins were identical in CD34+ cells and activated PBLs. Such proteins might be implicated in the highly efficient migration of CD34+ stem/progenitor cells from BM to PB after CT and G-CSF treatment. The cellular adhesion mechanisms involved in the BM homing of CD34+ cells are disrupted at least temporarily after CT. The Asp-ase proteolytic activity of granzyme B on extracellular matrix proteins could be used by progenitor cells for their rapid detachment from BM stromal cells and perforin might facilitate their migration across the endothelial cell barrier.
