Abstract To improve the grafting efficiency of transplanted murine hematopoietic progenitors, we briefly preincubated mouse bone marrow cells with interleukin-3 (IL-3) or granulocyte-macrophage colony-stimulating factor (GM-CSF) ex vivo before their transplantation into irradiated recipients. This treatment was translated into an increase in the seeding efficiency of colony-forming unit-spleen (CFU-S) and CFU-GM after transplantation. Not only was the concentration of CFU-S in the tibia increased 2 and 24 hours after transplantation, but the total cell number and CFU-S and CFU-GM concentrations were persistently higher in IL-3- and GM-CSF-treated groups 1 to 3 weeks after transplantation. In addition, the survival of animals as a function of transplanted cell number was persistently higher in IL-3- and GM-CSF- treated groups compared with controls. The data indicate that the pretreatment of marrow cells with IL-3 and GM-CSF before transplantation increases the seeding efficiency of hematopoietic stem cells and probably other progenitor cells after transplantation. This increased efficiency may be mediated by upward modulation of homing receptors. Therefore, ex vivo preincubation of donor marrow cells with IL-3 and GM-CSF may be a useful tactic in bone marrow transplantation.

Abstract The effects of mouse L-cell interferon (IFN) on growth of mouse bone marrow cells and their differentiation into macrophages and granulocytes were investigated in a liquid suspension culture system with two different types of colony-stimulating factor (CSF). Within 7 days, most bone marrow cells differentiated into macrophages in the presence of macrophage colony-stimulating factor (M-CSF) derived from mouse fibroblast L929 cells, but into both granulocytes (40%) and macrophages (23%) in the presence of a granulocyte-macrophage colony- stimulating factor (GM-CSF) from mouse lung tissue. IFN inhibited growth of bone marrow cells with both M-CSF and GM-CSF, but had 20 times more effect on bone marrow cells stimulated with M-CSF than on those stimulated with GM-CSF. A low concentration of IFN (50 IU/ml) stimulated production of macrophages by GM-CSF in liquid culture medium, whereas it selectively inhibited colony formation of macrophages in semisolid agar culture. IFN caused no detectable block of late stages of differentiation; mature macrophages and granulocytes were produced even when cell proliferation was inhibited by IFN. These results indicate that IFN preferentially affects growth and differentiation of the cell lineage of macrophages among mouse bone marrow cells.

Impaired host defense post-bone marrow transplant (BMT) is related to overproduction of prostaglandin E2(PGE2) by alveolar macrophages (AMs). We show AMs post-BMT overproduce granulocyte-macrophage colony-stimulating factor (GM-CSF), whereas GM-CSF in lung homogenates is impaired both at baseline and in response to infection post-BMT. Homeostatic regulation of GM-CSF may occur by hematopoietic/structural cell cross talk. To determine whether AM overproduction of GM-CSF influenced immunosuppression post-BMT, we compared mice that received BMT from wild-type donors (control BMT) or mice that received BMT from GM-CSF−/− donors (GM-CSF−/− BMT) with untransplanted mice. GM-CSF−/− BMT mice were less susceptible to pneumonia with Pseudomonas aeruginosa compared with control BMT mice and showed antibacterial responses equal to or better than untransplanted mice. GM-CSF−/− BMT AMs displayed normal phagocytosis and a trend toward enhanced bacterial killing. Surprisingly, AMs from GM-CSF−/− BMT mice overproduced PGE2, but expression of the inhibitory EP2receptor was diminished. As a consequence of decreased EP2receptor expression, we found diminished accumulation of cAMP in response to PGE2stimulation in GM-CSF−/− BMT AMs compared with control BMT AMs. In addition, GM-CSF−/− BMT AMs retained cysteinyl leukotriene production and normal TNF-α response compared with AMs from control BMT mice. GM-CSF−/− BMT neutrophils also showed improved bacterial killing. Although genetic ablation of GM-CSF in hematopoietic cells post-BMT improved host defense, transplantation of wild-type bone marrow into GM-CSF−/− recipients demonstrated that parenchymal cell-derived GM-CSF is necessary for effective innate immune responses post-BMT. These results highlight the complex regulation of GM-CSF and innate immunity post-BMT.

Abstract Interactions between different cytokines, extracellular matrix components, and various cell types inside the bone marrow microenvironment are believed to play important roles in the regulation of hematopoiesis. We observed that both interleukin-1 (IL-1) and 12-O- tetradecanoylphorbol-13-acetate (TPA) can stimulate the expression of IL-11 and granulocyte-macrophage colony-stimulating factor (GM-CSF) genes in a primate bone marrow stromal fibroblast cell line, PU-34. We also found that IL-1 or TPA-stimulated IL-11 and GM-CSF expression in PU-34 cells can be abolished by heparin, a class of molecules related to extracellular matrix components, glycosaminoglycans. Because the growth inhibitory signals provided by extracellular factors were less understood, the mechanisms of heparin inhibition of IL-11 and GM-CSF gene expression were further investigated. Our data demonstrate for the first time that heparin did not alter the transcription of endogenous IL-11 and GM-CSF genes or an exogenous IL-11 promoter construct containing an AP-1 sequence. Instead, heparin facilitated the degradation of the corresponding mRNAs. Through RNA gel shift assays, heparin-mediated mRNA destabilization was tentatively linked to its competition for mRNA binding proteins both in the cell-free system and in intact cells. Collectively, our findings suggest that varying degrees of heparin inhibition may provide a novel mechanism for the regulation of cytokine expression during the growth and differentiation of different lineages of hematopoietic cells.

Arginase I

l-Arginine transport is crucial for macrophage activation because it supplies substrate for the key enzymes nitric oxide synthase 2 and arginase I. These enzymes participate in classic and alternative activation of macrophages, respectively. Classic activation of macrophages is induced by type I cytokines, and alternative activation is induced by type II cytokines. The granulocyte macrophage colony-stimulating factor (GM-CSF), in addition to inducing proliferation and differentiation of macrophages, activates arginase I, but its action on l-arginine transport is unknown. We studied the l-arginine transporters that are active in mouse primary bone marrow-derived macrophages (BMM) and examined the effect of GM-CSF treatment on transport activities. Under basal conditions, l-arginine entered mainly through system y+L (>75%). The remaining transport was explained by system y+ (<10%) and a diffusion component (10–15%). In response to GM-CSF treatment, transport activity increased mostly through system y+ (>10-fold), accounting for about 40% of the total l-arginine transport. The increase in y+ activity correlated with a rise in cationic amino acid transporter (CAT)-2 mRNA and protein. Furthermore, GM-CSF induced an increase in arginase activity and in the conversion of l-arginine to ornithine, citrulline, glutamate, proline, and polyamines. BMM obtained from CAT2-knockout mice responded to GM-CSF by increasing arginase activity and the expression of CAT1 mRNA, which also encodes system y+ activity. Nonetheless, the increase in CAT1 activity only partially compensated the lack of CAT2 and l-arginine metabolism was hardly stimulated. We conclude that BMM present mainly y+L activity and that, in response to GM-CSF, l-arginine transport augments through CAT2, thereby increasing the availability of this amino acid to the cell.

Abstract A complete hematologic remission was achieved in a patient with therapy- related preleukemia and transfusion-dependent pancytopenia after treatment with recombinant human granulocyte-macrophage colony- stimulating factor (GM-CSF). The patient remained in remission for nearly 1 year despite the discontinuation of GM-CSF treatment. Several lines of evidence suggest that normal hematopoiesis was restored after GM-CSF treatment. First, the cytogenetic anomaly, which was present before GM-CSF, completely disappeared after three cycles of treatment. Cytogenetic conversion was documented by conventional karyotypic evaluation of mitotic bone marrow cell preparations as well as by premature chromosome condensation analysis of the nonmitotic cells of bone marrow and peripheral blood. Second, the growth pattern and cycle status of bone marrow granulocyte-macrophage (CFU-GM) and erythroid (BFU-E) progenitor cells were found to be normal during remission. Third, X chromosome-linked restriction fragment length polymorphism- methylation analysis of DNA from mononuclear cells (greater than 80% lymphocytes) and mature myeloid elements showed a polyclonal pattern. These findings suggest that restoration of hematopoiesis in this patient after GM-CSF treatment may have resulted from suppression of the abnormal clone and a selective growth advantage of normal elements.

Abstract Leukotrienes (LT) are mediators derived from the 5-lipoxygenase (5-LO) pathway, which play a role in host defense, and are synthesized by both monocytes (peripheral blood monocyte [PBM]) and neutrophils (PMN). Because 5-LO metabolism is reduced in alveolar macrophages and PMN from acquired immunodeficiency syndrome (AIDS) subjects, we investigated the synthesis of LT by PBM and PMN from these subjects. There was a reduction (74.2% ± 8.8% of control) in LT synthesis in PBM from human immunodeficiency virus (HIV)-infected compared with normal subjects. Expression of 5-LO (51.2% ± 8.8% of control), and 5-LO activating protein (FLAP) (48.5% ± 8.0% of control) was reduced in parallel. We hypothesized that this reduction in LT synthetic capacity in PBM and PMN was due to reduced cytokine production by CD4 T cells, such as granulocyte-macrophage colony-stimulating factor (GM-CSF). We treated 10 AIDS subjects with GM-CSF for 5 days. PBM 5-LO metabolism ex vivo was selectively increased after GM-CSF therapy and was associated with increased 5-LO and FLAP expression. PMN leukotriene B4(LTB4) synthesis was also augmented and associated with increased 5-LO, FLAP, and cytosolic phospholipase A2 expression. In conclusion, as previously demonstrated for PMN, PBM from AIDS subjects also demonstrate reduced 5-LO metabolism. GM-CSF therapy reversed this defect in both PBM and PMN. In view of the role of LT in antimicrobial function, cytokine administration in AIDS may play a role as adjunct therapy for infections.

Abstract The bcr-abl oncogene plays a critical role in causing chronic myelogenous leukemia (CML). Effective laboratory animal models of CML are needed to study the molecular mechanisms by which thebcr-abl oncogene acts in the disease progression of CML. We used a murine stem cell retroviral vector (MSCV) to transduce thebcr-abl/p210 oncogene into mouse bone marrow cells and found that expression of Bcr-Abl/p210 induced a myeloproliferative disorder that resembled the chronic phase of human CML in 100% of bone marrow transplanted mice in about 3 weeks. This CML-like disease was readily transplanted to secondary recipient mice. Multiple clones of infected cells were expanded in the primary recipients, but the leukemia was primarily monoclonal in the secondary recipient mice. Mutation analysis demonstrated that the protein tyrosine kinase activity of Bcr-Abl/p210 was essential for its leukemogenic potential in vivo. Interestingly, we found that the leukemic cells expressed excess interleukin-3 (IL-3) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in the diseased mice. These studies demonstrate that expression of Bcr-Abl can induce a CML-like leukemia in mice much more efficiently and reproducibly than in previously reported mouse CML models, probably due to efficient expression in the correct target cell(s). Our first use of this model for analysis of the molecular mechanisms involved in CML raises the possibility that excess expression of hematopoietic growth factors such as IL-3 and GM-CSF may contribute to the clinical phenotype of CML.
