Association between cytokine polymorphisms and recurrent pregnancy loss: A review of current evidence. Int J Gynaecol Obstet 2024.

Abstract
Cytokines are a type of protein that play an important role in the immune response and can also affect many physiological processes in the body. Cytokine polymorphisms refer to genetic variations or mutations that occur within the genes that code for cytokines, which may affect the level of cytokine production and function. Some cytokine polymorphisms have been associated with an increased risk of developing certain diseases, while others may be protective or have no significant effect on health. In recent years, the role of cytokine polymorphisms in the development of recurrent pregnancy loss (RPL) has been studied. RPL or miscarriage is defined as the occurrence of two or more consecutive pregnancy losses before the 20th week of gestation. There are diverse causes leading to RPL, including genetic, anatomical, hormonal, and immunological factors. With regard to cytokine polymorphisms, a few of them have been found to be associated with an increased risk of RPL, for instance, variations in the genes that code for interleukin-6, tumor necrosis factor-alpha, and interleukin-10. The exact mechanisms by which cytokine polymorphisms affect the risk of recurrent miscarriage are still being studied, and further research is essential to fully understand this complex condition. This brief review aims to summarize the recent literature on the association between cytokine polymorphisms and RPL.

Abstract
The variation in cytokine production during bacterial invasion of human intestinal epithelial cells (IECs) is a contributing factor for progression of the infection. A few Salmonella enterica Heidelberg strains isolated from poultry products harbor transmissible plasmids (TPs), including those that encode a type-IV secretion system. Earlier, we showed that these TPs are responsible for increased virulence during infection. This study examines the potential role of these TPs in cytokine production in IECs. This study showed that S. Heidelberg strains containing TPs (we refer as virulent strains) caused decreased interleukin (IL)-10 production in IECs after 1 h infection. The virulent strains induced a high level of tumor necrosis factor-α production under identical conditions. The virulent strains of S. Heidelberg also altered the production of IL-2, IL-17, and granulocyte macrophage colony-stimulating factor compared to an avirulent strain. As a part of infection, bacteria cross the epithelial barrier and encounter intestinal macrophages. Hence, we examined the cytotoxic mechanism of strains of S. Heidelberg in macrophages. Scanning electron microscopy showed cell necrosis occurs during the early stage of infection. In conclusion, virulent S. Heidelberg strains were able to modify the host cytokine profile during the early stages of infection and also caused necrosis in macrophages.

Abstract
Stem cell research has been widely studied over the last few years and has attracted increasing attention from researchers in all fields of medicine due to its potential to treat many previously incurable diseases by replacing damaged cells or tissues. As illustrated by hematopoietic stem research, understanding stem cell differentiation at molecular levels is essential for both basic research and for clinical applications of stem cells. Although multiple integrative analyses, such as genomics, epigenomics, transcriptomics and proteomics, are required to understand stem cell biology, proteomics has a unique position in stem cell research. For example, several major breakthroughs in HSC research were due to the identification of proteins such as colony-stimulating factors (CSFs) and cell-surface CD molecules. In 2007, the Human Proteome Organization (HUPO) and the International Society for Stem Cell Research (ISSCR) launched the joint Proteome Biology of Stem Cells Initiative. A systematic proteomics approach to understanding stem cell differentiation will shed new light on stem cell biology and accelerate clinical applications of stem cells.

Abstract
An imbalance of mucosal pro- and anti-inflammatory cytokines is crucial in the pathogenesis of inflammatory bowel disease (IBD). GM-CSF influences the development of hemopoietic cells. The precise role of GM-CSF in IBD remains to be elucidated. GM-CSF gene knockout (GM-CSF(-/-)) and wild-type (Wt) mice were challenged with 2.5% dextran sulfate sodium (DSS) for 7 days. The ensued clinical and pathological changes, macrophage infiltration, colonic cytokine production, and bacterial counts were examined. DSS-treated GM-CSF(-/-) mice developed more severe acute colitis than DSS-treated Wt mice, reflected by a greater body weight loss, more rectal bleeding, and aggravated histopathological changes. More infiltrating macrophages were observed in GM-CSF(-/-), compared with Wt mice following DSS challenge, correlating with monocyte chemoattractant protein-1 (MCP-1) production. The levels of colonic IL-17 and TNF-alpha were increased significantly in GM-CSF(-/-) mice, but not in Wt mice, following DSS administration. The level of IL-6 was increased by 1.5- and 2-fold in the colon of GM-CSF(-/-) and Wt mice, respectively, following DSS challenge. No significant changes in IL-4 and IFN-gamma were detected in Wt and GM-CSF(-/-) mice following DSS treatment. The bacteria recovery from colon was increased about 15- and 5-fold, respectively, in Wt mice and GM-CSF(-/-) mice following DSS challenge. These results suggest that GM-CSF(-/-) mice are more susceptible to acute DSS-induced colitis, possibly because of an impaired gut innate immune response as a result of diminished GM-CSF.

Abstract
Differentiation therapy of leukemia is the treatment of leukemia cells with biological or chemical agents that induce the terminal differentiation of the cancer cells. It is regarded as a novel and targeted approach to leukemia treatment, based on our better understanding of the hematopoietic process and the mechanisms of its deregulation during leukemogenesis. Clinically, differentiation therapy has been most successful in acute promyelocytic leukemia using all-trans-retinoic acid as the inducer, either alone or in combination with chemotherapy. This review presents evidence that a number of hematopoietic cytokines play important roles in both normal and aberrant hematopoietic processes. In vitro laboratory investigations in the past two decades using well-characterized myeloid leukemic cell lines and primary blast cells from leukemia patients have revealed that many hematopoietic cytokines can trigger lineage-specific differentiation of leukemia cells, which may have important implications in the clinical setting. Moreover, our current understanding of cytokine interactions and the molecular mechanisms of cytokine-induced leukemic cell differentiation will be discussed in the light of recent findings. Finally, ways in which laboratory research on cytokines in the differentiation therapy of leukemia can lead to the improved design of protocols for future clinical applications to leukemia therapy will also be addressed.

Abstract
The mechanism of pathological bone loss induced by estrogen deficiency has not been fully elucidated. It has been shown in recent animal studies that increased B lymphopoiesis induced by estrogen deficiency is involved in the mechanism of stimulated bone resorption. Mice transgenic for granulocyte colony-stimulating factor (G-CSF) (G-Tg) exhibit generalized osteopenia with an increase in osteoclast number and enhancement of bone resorption, which coexists with enhanced hematopoiesis. When ovariectomy was performed on G-Tg, it did not further reduce bone mass as revealed by radiography, dual-energy X-ray absorptiometry, and peripheral quantitative computed tomography. Ovariectomy increased the amount of colony-forming units of interleukin 7 (CFU-IL-7) by threefold in the marrow of normal mice in association with an increase in the number of B220-positive cells expressing the receptor activator of nuclear factor-kappaB ligand (RANKL). In contrast, the number of B220-positive cells expressing RANKL and CFU-IL-7 remarkably decreased in the marrow of G-Tg. Ovariectomy induced neither CFU-IL-7 nor B220-positive cells expressing RANKL in the marrow of G-Tg. Strong inhibition of B lymphopoiesis by G-CSF resulted in depletion of B cells expressing RANKL from the marrow, which may lead to resistance to bone loss due to ovariectomy. This observation suggests that B lymphopoiesis plays a possible role in bone loss in a condition of acute estrogen deficiency.

Abstract
Increased hematopoiesis, driven by colony-stimulating factors (CSFs), is known to occur in infectious diseases. However, whether Leishmania donovani component(s) can directly induce the synthesis and secretion of CSFs is not known. We report that L. donovani amastigote antigens soluble in culture medium (LDAA; 0.01-10 mg/kg), injected intravenously in BALB/c mice, induced the production of serum CSFs; maximum induction (128>16 colonies) occurred at 1 mg/kg. In vitro also, LDAA (0.01-1 mg/ml) induced mouse peritoneal macrophages (MØs) to elaborate CSFs in the conditioned medium (CM); 0.1 mg/ml LDAA appeared optimal (68+/-9 colonies). Both in vivo and in vitro, the kinetics of CSF production were similar with peak response occurring 24 h after stimulation and return to background levels by 72 h. A predominant approximately 12 kDa LDAA protein (LDAA-12) also induced CSF production, both in serum and CM, in a dose-and time-dependent manner. Rabbit anti-LDAA-12 antibody significantly (p<0.05) reduced both the LDAA-and LDAA-12-induced CSF production, in vitro. Functionally, the LDAA-12-induced CSFs, both in the serum and CM, appeared to be similar as they supported the formation of granulocyte (G), MØ (M) and GM colonies, in vitro, in similar proportion; GM colonies were maximum (>80%). Further, LDAA-12 induced significantly (p<0.05) high GM-CSF levels both in serum and CM (19+/-3 and 15+/-2 ng/ml, respectively), as compared to the controls. Neutralizing (100%) goat anti-mouse tumour necrosis factor-alpha (TNF-alpha) immunoglobulin G did not affect the LDAA-12-induced CSF production by MØs, indicating it to be TNF-alpha-independent. LDAA-12 induced de novo CSF production, as MØs co-treated with LDAA-12 and cycloheximide (50 microg/ml) did not elaborate CSFs. The CSF-inducing capability of LDAA-12 appeared to be heat (70 C; 1 h)-labile, destroyed by proteases (pronase E and trypsin) and was unaffected by sodium periodate treatment. In LDAA-12-treated mice, the splenic and femur colony forming unit-GM counts showed a maximum of 2.2- and 1.9-fold increase, respectively, as compared to the controls. These data are the first to directly demonstrate that L. donovani amastigote components can induce the production of CSFs that may play important role(s) in the pathogenesis of visceral leishmaniasis.

Abstract
The neuroimmunomodulatory effects of opiates during microbial infections are now well known; however, not much is known during leishmaniasis. Here, we report the effects of morphine on purified approximately 12-kDa component of Leishmania donovani amastigote antigen (LDAA-12)-induced colony-stimulating factor (CSF) production by mouse peritoneal macrophages (PMs) in vitro. Low concentrations (1 x 10(-9) and 1 x 10(-11) M) of morphine significantly (P < 0.05) augmented the production of CSFs, whereas high concentrations (1 x 10(-3) and 1 x 10(-5) M) inhibited CSF production. Morphine exerted a similar concentration-dependent biphasic effect on the LDAA-12-induced elaboration of granulocyte (G)-macrophage (M)-CSF (GM-CSF) and M-CSF by PMs in their conditioned medium, as quantified by using enzyme-linked immunosorbent assay. Furthermore, selective agonists of mu-(DAGO) and delta-(DPDPE) opioid receptors also, respectively, augmented and inhibited the production of CSFs. Pretreatment of PMs with naloxone (1 x 10(-5) M) significantly (P < 0.05) blocked the augmenting effect of morphine. In contrast, at 1 x 10(-5) M, naloxone lacked any effect on the inhibitory effect of morphine; however, its 100-fold higher concentration partially blocked it. This study, apparently for the first time, demonstrates that morphine, via surface opioid receptors, biphasically modulates the LDAA-12-induced CSF production by PMs, in vitro. These results thus show the implications of opiate abuse on the outcome of therapeutic interventions in areas where both visceral leishmaniasis and drug abuse are rampant.

Abstract
Blood formation by pluripotent stem cells and their progeny is thought to be regulated by receptor-ligand interactions between cell-substrate, cell-cell and cell-matrix in the bone marrow. Primitive stem cells form progenitors and, in their turn, these give rise to haemopoietic progeny which are more specifically committed in that they can form progressively fewer types of blood cells. Recently we have established that direct cell-cell communication via gap junctions may be part of this regulatory system. Connexin43 gap junctions metabolically couple the three dimensional meshwork of bone marrow stromal cells to form a functional syncytium in which some blood-forming cells are also coupled. The expression of gap junctions in the bone marrow is markedly upregulated when there is an urgent and substantial demand for blood-formation; for example, following cytotoxic injury after 5-fluorouracil or irradiation; or during neonatal blood-formation and in the epiphysis of growing bones. Chemical blockade of gap junctions blocks blood-formation in long-term cultures but is reversible after the blockade has been relieved. This short review highlights briefly the known regulatory mechanisms of blood-formation with especial attention to gap junctional communication.

Abstract
Mice heterozygously deficient in the p0 gene (P0(+/-)) are animal models for some forms of inherited neuropathies. They display a progressive demyelinating phenotype in motor nerves, accompanied by mild infiltration of lymphocytes and increase in macrophages. We have shown previously that the T lymphocytes are instrumental in the demyelination process. This study addresses the functional role of the macrophage in this monogenic myelin disorder. In motor nerves of P0(+/)- mice, the number of macrophages in demyelinated peripheral nerves was increased by a factor of five when compared with motor nerves of wild-type mice. Immunoelectron microscopy, using a specific marker for mouse macrophages, displayed macrophages not only in the endoneurium of the myelin mutants, but also within endoneurial tubes, suggesting an active role in demyelination. To elucidate the roles of the macrophages, we crossbred the myelin mutants with a spontaneous mouse mutant deficient in macrophage colony-stimulating factor (M-CSF), hence displaying impaired macrophage activation. In the P0-deficient double mutants also deficient in M-CSF, the numbers of macrophages were not elevated in the demyelinating motor nerves and demyelination was less severe. These findings demonstrate an active role of macrophages during pathogenesis of inherited demyelination with putative impact on future treatment strategies.

Abstract
OBJECTIVE To determine whether granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage CSF (M-CSF or CSF-1) are involved in the methylated bovine serum albumin/interleukin-1 (mBSA/IL-1)-induced arthritis model. METHODS Following systemic injection, IL-1 has been shown to augment a weak inflammatory response to mBSA in murine joints and to induce an acute erosive arthritis. GM-CSF and M-CSF have been implicated in inflammatory reactions, including those in joints, and have recently been shown to exacerbate murine arthritis. Since in vitro studies have found that IL-1 can enhance GM-CSF and M-CSF production, we reasoned that they might be playing a part in IL-1-mediated arthritis. GM-CSF-deficient (GM-CSF-/-) and M-CSF-deficient (op/op) mice were injected intraarticularly with mBSA and subcutaneously with IL-1. Arthritis was monitored histologically on day 7. Normal mice were also treated intraperitoneally with blocking monoclonal antibodies to GM-CSF and M-CSF, and to the M-CSF receptor. Numbers of macrophages (Mac-2 and F4/80 staining) were monitored, as was the number of cycling (bromodeoxyuridine-positive) cells. RESULTS GM-CSF-/- mice and normal mice treated with anti-GM-CSF antibody did not show IL-1-induced arthritis progression. There was a dramatic reduction in synovial cellularity, including reduced numbers of macrophages and cycling cells. The op/op mice did not develop mBSA/IL-1-induced disease, but blocking antibody to M-CSF or to the M-CSF receptor failed to diminish disease in normal mice. CONCLUSION GM-CSF is involved in the IL-1-induced arthritis that follows mBSA injection; M-CSF involvement in the model is also suggested, since op/op mice did not develop arthritis. These studies provide the first in vivo evidence for a role of GM-CSF, and possibly M-CSF, in the proinflammatory actions of IL-1.

Abstract
The importance of both granulocytes and macrophages in the response to Listeria monocytogenes infection make this infection a suitable choice to investigate the effects of Pluchea quitoc on hematopoiesis. A significant depletion of bone marrow granulocyte-macrophage progenitor cells (CFU-GM) was observed at 48 and 72 h after intraperitoneal infection of mice with 1 x 10(4) L. monocytogenes. However, the treatment of infected animals with P. quitoc ethanolic extract (250, 500 or 1000 mg/kg) given orally for 3 consecutive days prior to infection produced a stimulatory effect on myelopoiesis, restoring the number of CFU-GM to normal. This same dose-schedule also increased colony formation in normal mice as compared to controls. In addition, P. quitoc significantly enhanced survival of infected mice. Thus, it is probable that the ability of P. quitoc to induce a higher reserve of granulocyte-macrophage precursors in the bone marrow is of major significance in determining early resistance to infection.

Abstract
In this study we investigated the effects of the treatment with Chlorella vulgaris extract (CVE) on the hematopoietic response of granulocyte-macrophage colony-forming unit (CFU-GM) of mice infected with a sublethal dose of Listeria monocytogenes (1 x 10(4) organisms/animal). CVE was given orally as 50 mg/kg/day for 5 days. In the CVE treated/infected groups L. monocytogenes was administered at the end of CVE treatment. The colony stimulating activity of the serum (CSA) was also studied in all groups. Although no effects on CFU-GM, as compared to controls, were observed in the groups receiving CVE alone, the extract produced an increase in CSA levels as compared to controls. On the other hand, the presence of the infection led to a significant reduction in the numbers of CFU-GM as observed at 48 and 72 h after the infection, in spite of the significant increase in serum CSA activity. CVE treatment of infected animals restored the numbers of CFU-GM to control levels. In the treated/ infected group the increased serum CSA was significantly higher than that observed in the only infected group. The CVE treatment (50 and 500 mg/kg) of mice infected with a dose of 3 x 10(5) bacteria/animal, which was lethal for all the non-treated controls, produced a dose-response protection which led to a 20 and 52% survival, respectively. These results demonstrated that CVE produces a significant increase in the resistance of the animals infected with L. monocytogenes, and that this protection is due, at least in part, to increased CFU-GM in the bone marrow of infected animals.

Abstract
In this work we have investigated the growth and differentiation of bone marrow stem cells in mice bearing Ehrlich ascites tumor and treated with three dose-regimens of Dicyclopentadienyldichlorotitanium (IV) (DDCT). We also studied the presence of colony stimulating factors in the serum of DDCT-treated animals, as well as the effects of the drug on the survival of the tumor-bearing mice. The results demonstrated that the myelosuppression developed in the tumor-bearing animals is prevented by the administration of 1, 2 or 3 doses of 15 mg/kg DDCT. In the treatment with three doses, however, 23% of the animals died. Moreover, DDCT treatment in normal animals resulted in increased numbers of CFU-GM. We observed the presence of stimulating factors in the serum of drug-treated animals which induced the growth and differentiation of bone marrow progenitor cells from normal animals in vitro. On the other hand, in vitro addition of the drug to these cultures had no effect. Thus, we conclude that the drug protects against the myelosuppression induced by the tumor and that this protection may be related to an indirect action of the drug.

Abstract
Hematopoiesis is the process by which mature, functional progeny of the eight major lineages of blood cells are produced from a hierarchy of progressively less mature progenitor and stem cells. The control of hematopoiesis involves intimate cellular interactions between developing blood cells and stromal elements as well as regulation by soluble cytokines, that may act locally in the bone marrow environment or at remote tissue sites. In excess of twenty cytokines that stimulate the production and/or function of hematopoietic cells have now been cloned and are available in purified, recombinant form. The colony-stimulating factors, erythropoietin and the recently discovered thrombopoietin are key regulators of granulocyte/macrophage, erythroid and megakaryocyte/platelet production respectively. The activities of these cytokines have been extensively studied, both in vitro and in vivo, and recent analysis of mice genetically engineered to lack these regulators or their cell surface receptors have provided profound insights into their essential physiological roles. These studies have culminated in the development of these cytokines as valuable clinical reagents.

Abstract
We studied the effects of M-CSF on cytokine induction in vivo by LPS or by bacterial infection by comparing between the serum cytokine levels of mice administered with and without M-CSF. M-CSF at 250 micrograms/kg/day for 3 days significantly augmented serum IL-6 level induced by a subsequent injection of 25 micrograms/kg of LPS. The augmented IL-6-induction was dose-dependent from 50 to 1250 micrograms/kg/day of M-CSF, and required 2- to 3-doses of M-CSF at 250 micrograms/kg/day. Mice primed with M-CSF induced IL-6 in response to a 5-fold lower dose of LPS, and also produced higher levels of IL-1 alpha, IL-10, GM-CSF, TNF-alpha, and IFN-gamma than control mice. The priming effect of M-CSF was transient and reversible, and elicited independently of T-cells. An injection with intact bacteria, such as Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus also induced IL-6 in normal mice, and M-CSF administration augmented the induction of these cytokines. These results showed that M-CSF positively regulates LPS-dependent and -independent cytokine induction, suggesting a defensive effect against infectious agents through enhanced cytokine production.

Abstract
OBJECTIVE To examine the effect of granulocyte-macrophage colony stimulating factor (GM-CSF) on disease progression in the collagen induced arthritis (CIA) model in mice. METHODS DBA/1 mice were primed for a suboptimal CIA response by intradermal injection of chick type II collagen without a secondary immunisation. Three weeks after immunisation the mice were given four to five consecutive daily intraperitoneal injections of recombinant murine GM-CSF (15 micrograms; 5 x 10(5) U), or vehicle, and arthritis development was monitored by clinical scoring of paws and calliper measurements of footpad swelling. At approximately six to eight weeks after immunisation mice were killed, their limbs removed and processed for histological analyses of joint pathology. RESULTS Control animals receiving a single immunisation with collagen exhibited a varied CIA response both in terms of incidence and severity. Mice treated with GM-CSF at 20 to 25 days after immunisation with collagen had a consistently greater incidence and more rapid onset of disease than the vehicle treated control mice, based on clinical assessment. GM-CSF treated mice showed higher average clinical scores and greater paw swelling than controls. Histological analyses of joints reflected the clinical scores with GM-CSF treated mice displaying more pronounced pathology (synovitis, pannus formation, cartilage and bone damage) than control mice. CONCLUSION GM-CSF is a potent accelerator of the pathological events leading to chronic inflammatory polyarthritis in murine CIA supporting the notion that GM-CSF may play a part in inflammatory polyarthritis, such as rheumatoid arthritis.

Abstract
Abstract
In the setting of hybrid resistance, parental C57BL/6 bone marrow (BM) grafts are vigorously rejected by lethally irradiated (C57BL/6xDBA/2) F1 mice. However, F1 mice pretreated by continuous administration of granulocyte colony-stimulating factor (G-CSF ) with a miniosmotic pump before BM grafting developed day-8 splenic colonies of donor origin. This inhibitory effect on rejection was reversible because F1 mice regained the capacity to reject parental BM when the pump ceased functioning. The appearance of only a small number of colonies with the administration of G-CSF soon after BM grafting suggested the importance in producing this inhibitory effect of pre-exposure of host mice to G-CSF. Because G-CSF administration with a syngeneic combination did not influence the number of colonies, an altered distribution of grafted precursors was unlikely. The absence of a reduction in the number of NK1.1-positive cells in G-CSF–treated mice suggested functional impairment of natural killer cells, major effectors in hybrid resistance, but further study is necessary to elucidate the mechanism underlying this phenomenon. However, our results indicate the importance of G-CSF as a regulator in a certain type of immune response and raise the possibility of clinical application in transplantation medicine.

Abstract
Transplanted allogeneic marrow grafts often fail to engraft in a lethally irradiated host. Resistance to hemopoietic allograft is a complexed phenomenon involving multiple components. To study the involvement of a hemopoietic cytokine, which was known to play a role for stem cell function, we established lines of mice that were transgenic for human granulocyte colony-stimulating factor (hG-CSF). Elevated and constitutive expression was found in sera (1,041 +/- 242 pg/ml) of these transgenic mice regardless of their sexes and ages. Strong neutrophilic granulocytosis correlated with the elevated G-CSF activity in transgenic mice but not in littermate controls, establishing a functional expression of this cytokine. In lethally irradiated mice transgenic for G-CSF, infusion of fully allogeneic marrow cells induced donor-derived spleen colony. Growth of hemopoietic allografts appeared to be similar to those of syngeneic marrow cells, which indicates inhibition of resistance for allogeneic marrow grafts. Because of a positive correlation, involvement of natural killer (NK) cells in resistance of transplanted allografts has been suggested. Inocula of NK-sensitive lymphoma cells were, however, vigorously rejected in the G-CSF-transgenic mice. This observation indicates that G-CSF may play a role in engraftment of transplanted allogeneic marrow grafts and may represent a component of mechanisms of hemopoietic resistance. Furthermore, this result may be an indication that alloresistance and NK cells use different mechanisms to resist each target.

Abstract
Transplanted allogeneic marrow cells often fail to engraft in a lethally irradiated host. This phenomenon, termed resistance to allogeneic marrow grafts or alloresistance, is well documented, although its mechanism is not yet understood. Transplantation of major histocompatibility complex disparate allogeneic marrow cells into mice transgenic for granulocyte colony-stimulating factor (G-CSF) showed donor-derived spleen colonies (CFU-S) and resulted in stable allogeneic chimerism with excellent survival (100% up to 40 days and 89% up to 120 days). Under the same experimental conditions, all the littermate controls failed to show CFU-S and died shortly after marrow transplantation. Thus, resistance to allogeneic marrow cells appeared to be severely impaired in this transgenic mouse. The observation that neutralizing antibody against G-CSF restored allo-resistance in G-CSF transgenic mice and that CFU-S was inducible upon administration of recombinant G-CSF using a mini-osmotic pump in nontransgenic recipients, suggests that an elevated level of this cytokine is important for the inhibition of allo-resistance. Thus, G-CSF was found to play a role in allogeneic resistance to marrow grafts and the G-CSF-transgenic mice provide a useful model to study the inhibition of the resistance. The inhibition of allo-resistance may be useful in preparing allogeneic bone marrow chimeras in both experimental and clinical settings.

Abstract
The absorption, CD, and fluorescence emission spectra, and the fluorescence emission and depolarization lifetimes of the human granulocyte-macrophage colony-stimulating factor (hGM-CSF) and related peptides previously tested for their immunological activity, were measured in water at various pHs and temperatures to obtain information on their conformation in solution. The aim was to correlate the amino acid sequences, and the chain conformations and dynamics of the peptides, with their immunological properties. The CD spectrum of hGM-CSF revealed, as expected, a structure in solution similar to that in the crystalline state, but the fluorescence data suggest that the Trp 122 residue is more accessible to the solvent than the x-ray data would lead one to expect. They also suggest that some flexibility exists between the protein's two domains, one made up of the alpha-helices A and C and the other of the alpha-helices B and D plus the two beta-strands. In aqueous solution, none of the tested peptide CD spectra could be linked to a recognizable ordered conformation, i.e., an alpha-helix or a beta-sheet. The fluorescence of the peptide 11-24 suggests that the Trp 13 residue may appear in two types of situations: (a) in aqueous solution and (b) within a globular structure. Its CD spectra show that the tryptophan residue exists in both cases in a highly asymmetric environment independent of the pH.

Abstract
A specific radioimmunoassay was employed to demonstrate that human articular cartilage and chondrocyte monolayers in organ and cell culture, respectively, produce macrophage colony-stimulating factor (M-CSF) in response to stimulation with interleukin-1 alpha (IL-1 alpha), IL-1 beta, tumor necrosis factor alpha (TNF alpha) and TNF beta. Optimum doses were 10-100 U/ml for IL-1 (0.06-0.6 nM IL-1 alpha; 0.02-0.2 nM IL-1 beta) and 1-10 nM for TNF alpha. Low levels of M-CSF were observed in the supernatants of nonstimulated cultures while increased levels of M-CSF in response to IL-1 alpha and TNF alpha were detected following 2 h exposure to the cytokines. IL-1 alpha and TNF alpha did not show synergy for the production of M-CSF when both cytokines were added to cultures. Actinomycin D and cycloheximide inhibited both the basal and IL-1 alpha-induced production of M-CSF, suggesting a requirement for de novo RNA and protein synthesis. Cytokine-induced M-CSF production was also inhibited by the antiinflammatory corticosteroid, dexamethasone, but not by the cyclooxygenase inhibitor, indomethacin. The cytokines IL-4, IL-6, platelet-derived growth factor, leukemia inhibitory factor, transforming growth factor-beta and interferons -alpha and -gamma, each had little or no effect on M-CSF levels, while basic fibroblast growth factor, lipopolysaccharide, and retinoic acid were each weak stimuli. We propose that chondrocyte M-CSF production in response to IL-1 and TNF alpha, and the concurrent destruction of cartilage by these cytokines, could provide a mechanism for the chronic nature of rheumatoid disease.

Abstract
To identify the therapeutic efficacy of granulocyte colony stimulating factor (G-CSF) in severe sepsis, we examined its effect on the mortality and pathological changes in vital organs using the rat lethal sepsis model. Rats were given 15 micrograms of recombinant human (rh)G-CSF after the onset of peritonitis brought about by cecal ligation and puncture. The mortality rate after 72 h was significantly decreased by administration of 15 micrograms of rhG-CSF (p < 0.001). In addition, the administration of rhG-CSF induced an improvement in liver and renal functions. It also produced marked pathological improvement in the lungs. These results strongly indicated that administration of rhG-CSF, even after the onset of sepsis, was effective in decreasing the mortality from peritonitis-induced multiple organ failure, and this finding was clearly useful in the clinical treatment of such sepsis-induced critical illness.

Abstract
A large, and growing, group of glycoprotein regulators is now recognized to control the proliferation, maturation and functional activity of the eight major families of blood cells. Each hemopoietic regulator is the product of multiple cell types and there is a puzzling redundancy of regulators able to stimulate each subfamily of hemopoietic cells. Each regulator is polyfunctional but it remains unclear how a single type of activated receptor is able to initiate the diverse cellular responses induced.

Abstract
The kinetics of GM-CSF and G-CSF secretion by purified adherent human monocytes were studied by quantitative immunoassays. Interleukin-1 (IL-1); 4-40 ng/ml and E. coli lipopolysaccharide (LPS); 0.1-1.00 ng/ml, were the most effective stimuli and induced dose-dependent secretion of both GM-CSF and G-CSF. Secretion of newly synthesized CSF was detectable 3-6 hours after stimulation and continued for approximately 24 h. Twenty minutes pulse exposure to LPS was sufficient to induce half maximum secretion of GM-CSF, and after 24-36 h the adherent monocytes could not be restimulated. Neither GM-CSF nor TNF could down-regulate the secretion of GM-CSF. IL-3 induced a minor secretion of GM-CSF whereas TNF, G-CSF, M-CSF and IFN-gamma were unable to induce GM-CSF secretion. In addition to LPS and IL-1, GM-CSF and to a minor degree TNF induced G-CSF secretion. Enriched T lymphocytes secreted GM-CSF, but not G-CSF, after stimulation with PHA or staphylococcal enterotoxin A (SEA), whereas LPS and IL-1 were without stimulatory effects. We also noted that enriched T lymphocytes added to LPS-stimulated adherent monocytes at ratios of 1:10 or more inhibited, in a dose-dependent fashion, GM-CSF secretion by 13-55%. These findings add new quantitative data on CSF secretion by human monocytes.

Abstract
The production and maturation of blood cells from the eight major blood cell lineages is a complex and continuous process, which is largely controlled by specific glycoprotein hemopoietic regulators. These regulators also control the functional activity of the blood cells through eliciting a diverse set of intracellular responses initiated by a regulator-specific membrane receptor. Twenty of these regulators have now been characterized, and their mass production has led to four already being licensed for clinical use in disease states involving subnormal blood cell formation.

Abstract
Cells of the continuous murine hemopoietic cell line FDC-P1 expressing macrophage-colony-stimulating factor (M-CSF) receptors following retroviral insertion of murine c-fms cDNA proliferated clonally when stimulated by granulocyte/macrophage (GM)-CSF, multipotential CSF, or M-CSF. However, M-CSF combined with either GM-CSF or multi-CSF, even at low CSF concentrations, strongly inhibited colony formation, with loss of clonogenicity in affected cells accompanied by increased macrophage differentiation. Stimulation by these CSF combinations did not induce short-term changes in CSF receptor expression or internalization. FDC-P1 cells expressing another inserted tyrosine kinase receptor, basic fibroblast growth factor receptor, did not exhibit suppression when GM-CSF was combined with fibroblast growth factor. This phenomenon of synergistic suppression may have relevance for the future clinical use of combinations of CSFs, because a potentially similar suppression is also observable with some normal macrophage progenitor cells.

In clonal cultures of normal mouse marrow cells, combination of granulocyte, granulocyte-macrophage, or multipotential colony-stimulating factor (G-CSF, GM-CSF, or multi-CSF, respectively) with stem cell factor (SCF) did not alter the number of blast colonies stimulated to develop compared with SCF alone but induced an up to 25-fold increase in their mean cell content and an up to 6-fold increase in their mean progenitor cell content. Costimulation of blast colony formation by SCF plus G-CSF did not change the relative frequency of progenitor cells of different types within the colonies compared with colonies stimulated by SCF alone. However, combination of GM-CSF or multi-CSF with SCF significantly increased the relative frequency of granulocytic progenitors and, for multi-CSF, also of eosinophil progenitor cells. These changes in the relative frequencies of progenitor cells committed to the various lineages support the hypothesis that hemopoietic regulators have some ability to induce selective lineage commitment in the progeny of multipotential cells.
