Abstract
Granulibacter bethesdensis can infect patients with chronic granulomatous disease, an immunodeficiency caused by reduced phagocyte NADPH oxidase function. Intact G. bethesdensis (Gb) is hypostimulatory compared to Escherichia coli, i.e., cytokine production in human blood requires 10-100 times more G. bethesdensis CFU/mL than E. coli. To better understand the pathogenicity of G. bethesdensis, we isolated its lipopolysaccharide (GbLPS) and characterized its lipid A. Unlike with typical Enterobacteriaceae, the release of presumptive Gb lipid A from its LPS required a strong acid. NMR and mass spectrometry demonstrated that the carbohydrate portion of the isolated glycolipid consists of α-Manp-(1→4)-β-GlcpN3N-(1→6)-α-GlcpN-(1⇿1)-α-GlcpA tetra-saccharide substituted with five acyl chains: the amide-linked N-3' 14:0(3-OH), N-2' 16:0(3-O16:0), and N-2 18:0(3-OH) and the ester-linked O-3 14:0(3-OH) and 16:0. The identification of glycero-d-talo-oct-2-ulosonic acid (Ko) as the first constituent of the core region of the LPS that is covalently attached to GlcpN3N of the lipid backbone may account for the acid resistance of GbLPS. In addition, the presence of Ko and only five acyl chains may explain the >10-fold lower proinflammatory potency of GbKo-lipidA compared to E. coli lipid A, as measured by cytokine induction in human blood. These unusual structural properties of the G.bethesdensis Ko-lipid A glycolipid likely contribute to immune evasion during pathogenesis and resistance to antimicrobial peptides.

Abstract
Plasma gelsolin (pGSN) is the secreted isoform of an intracellular actin remodeling protein found in high concentrations in human plasma. Clinical studies demonstrate reduced pGSN concentrations in several disease states, including severe trauma, burns, and sepsis. Markedly decreased pGSN concentrations in these conditions precede and predict adverse clinical outcomes. In this study, we measured pGSN in patients with chronic granulomatous disease (CGD), a primary immunodeficiency characterized by recurrent infections and dysregulated inflammation. pGSN was quantified using a sandwich ELISA in plasma from healthy volunteers, clinically stable CGD patients, and X-linked CGD carriers and in sera from 12 CGD patients undergoing bone marrow transplantation. pGSN was also quantified in healthy volunteers challenged with intravenous endotoxin. pGSN concentrations were lower in CGD patients without active infection or systemic inflammation compared with healthy control subjects. In CGD patients undergoing bone marrow transplantation, pGSN concentrations increased significantly following successful transplant. X-linked carriers of CGD had normal pGSN. Despite reduction of pGSN in CGD patients, we did not detect significant changes in pGSN over 24 h following challenge of healthy volunteers with intravenous endotoxin (4 ng/kg) that elicited a febrile response. We describe, for the first time, significantly lower pGSN in clinically stable patients with CGD compared with age- and sex-matched healthy volunteers. Low pGSN levels in CGD patients significantly increased following bone marrow transplantation. X-linked carriers of CGD had normal pGSN. In healthy volunteers challenged with intravenous endotoxin, pGSN is not an acute phase reactant.

Abstract
Interferon-γ (IFN-γ) plays an important role in innate and adaptive immunity against intracellular infections and is used clinically for the prevention and control of infections in chronic granulomatous disease (CGD) and inborn defects in the IFN-γ/interleukin (IL)-12 axis. Using transcriptome profiling (RNA-seq), we sought to identify differentially expressed genes, transcripts and exons in Epstein-Barr virus-transformed B lymphocytes (B-EBV) cells from CGD patients, IFN-γ receptor deficiency patients, and normal controls, treated in vitro with IFN-γ for 48 hours. Our results show that IFN-γ increased the expression of a diverse array of genes related to different cellular programs. In cells from normal controls and CGD patients, IFN-γ-induced expression of genes relevant to oxidative killing, nitric oxide synthase pathway, proteasome-mediated degradation, antigen presentation, chemoattraction, and cell adhesion. IFN-γ also upregulated genes involved in diverse stages of messenger RNA (mRNA) processing including pre-mRNA splicing, as well as others implicated in the folding, transport, and assembly of proteins. In particular, differential exon expression of WARS (encoding tryptophanyl-transfer RNA synthetase, which has an essential function in protein synthesis) induced by IFN-γ in normal and CGD cells suggests that this gene may have an important contribution to the benefits of IFN-γ treatment for CGD. Upregulation of mRNA and protein processing related genes in CGD and IFNRD cells could mediate some of the effects of IFN-γ treatment. These data support the concept that IFN-γ treatment may contribute to increased immune responses against pathogens through regulation of genes important for mRNA and protein processing.

Abstract
Many previous reports have indicated that atypical femur fractures (AFFs) are associated with the administration of bisphosphonates (BPs). A number of risk factors and hypotheses regarding the pathogenesis of AFFs have been reported to date. The purpose of the present study was to identify the factors associated with AFFs in Japanese individuals and to elucidate the association between bone metabolism and AFFs by evaluating bone turnover markers (BTMs). We prospectively reviewed all patients with femur fractures and identified the patients with AFFs and typical femur fractures (TFFs). We collected the demographic and clinical data that were relevant to the present study, namely age, gender, affected side, affected site, concomitant medical history, and comorbid conditions, and measured the levels of BTMs within 24h after trauma. Welch's test and Fisher's exact probability test were used for the statistical analyses. A total of 338 patients, including 10 patients with AFFs and 328 patients with TFFs, were analyzed under the inclusion criteria. The use of BPs (p<0.001) and collagen disease and chronic granulomatous disease (CD/CGD) (p=0.025) were more frequently observed in patients with AFFs than in patients with TFFs, while the levels of BTMs, including N-terminal propeptides of type 1 procollagen (P1NP), isoform 5b of tartrate-resistant acid phosphatase (TRACP-5b) and undercarboxylated osteocalcin (ucOC) were significantly lower in patients with AFFs than in patients with TFFs. Furthermore, the level of TRACP-5b was found to be significantly lower in patients with atypical subtrochanteric fractures than in atypical diaphyseal fractures (p=0.025). Moreover, the levels of P1NP (p=0.016) and TRACP-5b (p=0.015) were found to be significantly lower in patients with AFFs than in patients with TFFs in a subgroup analysis of BPs users. The use of BPs was considered to be a factor associated with AFFs. Our comparison of the BTMs in patients with AFFs and TFFs indicated that the severe suppression of bone turnover was associated with the pathogenesis of AFFs. The extent of the influence of suppressed turnover on the pathogenesis of AFFs may differ depending on the fracture site.

Abstract
Patients with hyperimmunoglobulin E syndrome (HIES) and chronic granulomatous disease (CGD) have prominently increased immunoglobulin (Ig) E levels. We present a 9-year-old boy with medical history revealing recurrent pneumonia, suppurative lymphadenitis, diarrhea, and otitis. The patient was hospitalized with severe pneumonia. The examination showed tachypnea, crackles at the right and left base of the lung, freckles on his face, red-hair, gingivitis, a high arched palate, and retained primary dentition. Serum IgE level was markedly increased. Nevertheless, patient did not have STAT3 or DOCK8 mutation, characteristic of HIES. Neutrophil function test with dihydrorhodamine (DHR) showed X linked-CGD pattern and molecular analysis of DNAshowed a splice site mutation (c.338-1G > A) in CYBB gene. Herein, we present a case of CGD with selective IgA deficiency. Laboratory findings and elevated IgE mimic the features seen in HIES. Thus, CGD must be considered as a differential diagnosis in patients with elevated Ig E.

Abstract
Chronic granulomatous disease (CGD) and inflammatory bowel disease (IBD) have overlapping gastrointestinal manifestations. Serum antibodies to intestinal microbial antigens in IBD are thought to reflect a loss of tolerance in the setting of genetically encoded innate immune defects. CGD subjects studied here, with or without colitis, had considerably higher levels of ASCA IgA, ASCA IgG, anti-OmpC, anti-I2, and anti-CBir1, but absent to low pANCA, compared to IBD-predictive cutoffs. Higher antibody levels were not associated with a history of colitis. Except for higher ASCA IgG in subjects <18 years, antibody levels were not age-dependent. In comparison, 7 HIES subjects expressed negative to low antibody levels to all of these antigens; none had colitis. Our results suggest that markedly elevated levels of antimicrobial antibodies in CGD do not correlate with a history of colitis but may reflect a specific defect in innate immunity in the face of chronic antigenic stimulation.

Abstract
Chronic granulomatous disease (CGD) is a primary immunodeficiency disorder caused by inherited defects in the nicotinamide adenine dinucleotide phosphate oxidase complex. The neutrophils of patient with CGD can ingest bacteria normally, but the oxidative processes that lead to superoxide anion formation, hydrogen peroxide production, nonoxidative pathway activation, and bacterial killing are impaired. Serious infections result from microorganisms that produce catalase. Immunoglobulin levels of patients with CGD are usually normal or elevated. We describe a patient with CGD associated with hypogammaglobulinemia, an unusual co-occurrence.

Abstract
BACKGROUND Failure to generate phagocyte-derived superoxide and related reactive oxygen intermediates (ROIs) is the major defect in chronic granulomatous disease, causing recurrent infections and granulomatous complications. Chronic granulomatous disease is caused by missense, nonsense, frameshift, splice, or deletion mutations in the genes for p22(phox), p40(phox), p47(phox), p67(phox) (autosomal chronic granulomatous disease), or gp91(phox) (X-linked chronic granulomatous disease), which result in variable production of neutrophil-derived ROIs. We hypothesized that residual ROI production might be linked to survival in patients with chronic granulomatous disease. METHODS We assessed the risks of illness and death among 287 patients with chronic granulomatous disease from 244 kindreds. Residual ROI production was measured with the use of superoxide-dependent ferricytochrome c reduction and flow cytometry with dihydrorhodamine oxidation assays. Expression of NADPH oxidase component protein was detected by means of immunoblotting, and the affected genes were sequenced to identify causal mutations. RESULTS Survival of patients with chronic granulomatous disease was strongly associated with residual ROI production as a continuous variable, independently of the specific gene affected. Patients with mutations in p47(phox) and most missense mutations in gp91(phox) (with the exception of missense mutations in the nucleotide-binding and heme-binding domains) had more residual ROI production than patients with nonsense, frameshift, splice, or deletion mutations in gp91(phox). After adolescence, mortality curves diverged according to the extent of residual ROI production. CONCLUSIONS Patients with chronic granulomatous disease and modest residual production of ROI have significantly less severe illness and a greater likelihood of long-term survival than patients with little residual ROI production. The production of residual ROI is predicted by the specific NADPH oxidase mutation, regardless of the specific gene affected, and it is a predictor of survival in patients with chronic granulomatous disease.

Abstract
Chronic granulomatous disease (CGD) is a rare primary immunodeficiency caused by mutations of one of the subunits of phagocyte reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase leading to decreased or complete absence of neutrophil oxidative burst. We report the clinical and laboratory findings in two young unrelated females 14 and 9 years of age and natives of Tahiti and Reunion Islands, respectively, with severe X-linked granulomatous disease. In both cases, the infectious pattern was unusual, with convergent symptoms suggesting underlying mycobacterial infection. Functional analysis revealed low residual NADPH oxidase activity with about 5-10% of normal neutrophil population. De novo null mutations affecting the CYBB gene that encodes the gp91 protein were found in both cases in the heterozygous state (in patient 1, p.Arg130X in exon 5, and in patient 2, a novel insertion in exon 6, c.632_633insCATC). Methylation analysis confirmed that phenotype expression was linked to skewed X inactivation and showed that the de novo mutation arose on the maternally inherited chromosome in one case and on the paternally inherited chromosome in the other case. In conclusion, X-linked CGD carriers could therefore be at risk for severe infectious diseases depending on the skewed X inactivation pattern and the infectious context.

Abstract
The killing of microorganisms by neutrophils causes degranulation of azurophilic, specific, and gelatinase granules into the formed phagolysosomes. During the degranulation process, increased surface expression of CD63 (localized in the azurophilic granules of resting neutrophils) and CD66b/CD67 (from specific granules) can be detected. This results from the fusion of the granule membrane, containing these markers, with a plasma membrane. Release of granule content into the phagolysosomes or the extracellular environment occurs not only upon proper cell activation but also upon tissue injury. We compared expression of degranulation markers on neutrophils from chronic granulomatous disease (CGD) patients and healthy volunteers. Surface expression of CD63 in non-stimulated and phorbol 12-myristate 13-acetate (PMA)-stimulated neutrophils, bactericidal activity of serum, and alpha-defensins level (HNP 1-3) in plasma of CGD patients were significantly higher in comparison with healthy volunteers. At the same time, the levels of intracellular HNP 1-3 in CGD neutrophils were lower than in normal neutrophils. Thus, our data revealed augmented degranulation of azurophilic neutrophil granules in CGD, which might play a role in tissue destruction observed in this disease.

Abstract
Gene transfer into hematopoietic stem cells has been used successfully for correcting lymphoid but not myeloid immunodeficiencies. Here we report on two adults who received gene therapy after nonmyeloablative bone marrow conditioning for the treatment of X-linked chronic granulomatous disease (X-CGD), a primary immunodeficiency caused by a defect in the oxidative antimicrobial activity of phagocytes resulting from mutations in gp91(phox). We detected substantial gene transfer in both individuals' neutrophils that lead to a large number of functionally corrected phagocytes and notable clinical improvement. Large-scale retroviral integration site-distribution analysis showed activating insertions in MDS1-EVI1, PRDM16 or SETBP1 that had influenced regulation of long-term hematopoiesis by expanding gene-corrected myelopoiesis three- to four-fold in both individuals. Although insertional influences have probably reinforced the therapeutic efficacy in this trial, our results suggest that gene therapy in combination with bone marrow conditioning can be successfully used to treat inherited diseases affecting the myeloid compartment such as CGD.

Abstract
NADPH oxidase generates reactive oxygen species that are essential to innate immunity against microbes. Like most enzymes, it is sensitive to pH, although the relative importance of pH(o) and pH(i) has not been clearly distinguished. We have taken advantage of the electrogenic nature of NADPH oxidase to determine its pH dependence in patch-clamped individual human eosinophils using the electron current to indicate enzyme activity. Electron current stimulated by PMA (phorbol myristate acetate) was recorded in both perforated-patch configuration, using an NH4+ gradient to control pH(i), and in excised, inside-out patches of membrane. No electron current was detected in cells or excised patches from eosinophils from a patient with chronic granulomatous disease. When the pH was varied symmetrically (pH(o) = pH(i)) in cells in perforated-patch configuration, NADPH oxidase-generated electron current was maximal at pH 7.5, decreasing drastically at higher or lower values. Varying pH(o) and pH(i) independently revealed that this pH dependence was entirely due to effects of pH(i) and that the oxidase is insensitive to pH(o). Surprisingly, the electron current in inside-out patches of membrane was only weakly sensitive to pH(i), indicating that the enzyme turnover rate per se is not strongly pH dependent. The most likely interpretation is that assembly or deactivation of the NADPH oxidase complex has one or more pH-sensitive steps, and that pH-dependent changes in electron current in intact cells mainly reflect different numbers of active complexes at different pH.

Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplantation for chronic granulomatous disease (CGD) is associated with a significant risk of transplant-related mortality. Adult age, overt infection, and residual inflammatory disease at transplant are major risk factors. METHODS Here we report the favorable outcome after bone marrow transplantation in three high-risk adult CGD patients (ages 18, 35, and 39) with severe disease-related complications (overt pneumonia, liver abscess, steroid-dependent granulomatous colitis, diabetes, restrictive lung disease, renal insufficiency, epilepsia). Bone marrow donors were human leukocyte antigen-matched related or unrelated. The conditioning regimen consisted of 2 x 4 mg/kg oral busulphan (d -3, -2), fludarabine 6 x 30 mg/qm (d -7 to -2), rabbit anti-T-cell-globulin (Fresenius) 4 x 10 mg/kg (d -4 to -1). Graft versus host disease prophylaxis consisted of cyclosporine A and mycophenolate-mofetil. RESULTS Mean neutrophil and platelet engraftment was observed at day +18.5 and +22.5, respectively. All infectious and inflammatory lesions resolved and restrictive lung disease improved. No signs of grade II-IV acute or chronic graft versus host disease were observed. With a follow-up of 12 to 27 months, all patients are alive and well with full donor chimerism, normalized superoxide production, and documented T- and B-cell function. CONCLUSION This modified reduced intensity conditioning protocol is a promising treatment modality for high-risk adult CGD patients.

Abstract
The transfusion of granulocytes to restore host defenses in severely granulocytopenic patients or in patients with defective granulocyte functions has been studied for more than 60 years. However, inadequate dosage of cells and inconsistent efficacy has limited the usage of these transfusions. Recently, the use of mobilizing agents such as granulocyte colony stimulating factors and dexamethasone has renewed interest in these treatment modalities. The present study is conducted to determine an appropriate method of enriched granulocyte collection with Fresenius AS.TEC.204 cell separator (Fresenius, Bad Homburg, Germany) and to evaluate the preliminary clinical results of granulocyte transfusion therapy in patients with chronic granulomatous disease and invasive Aspergillosis in parallel with in vitro granulocyte function. Three patients who have been treated for chronic granulomatous disease and invasive Aspergillosis received a total of 20 granulocyte transfusions. To mobilize granulocytes, healthy donors were given 450 microg of granulocyte colony-stimulating factor (G-CSF) subcutaneously and 8 mg of dexamethasone orally approximately 12 h before collection. Five microg/kg/day of G-CSF was also subcutaneously administered prior to granulocyte transfusions. The first patient received 4; the second, 14 and the third, 2 transfusions. The granulocyte count given to these patients ranged between 0.4 and 3.0 x 10(9)/kg. Most transfusions were well tolerated. The nitroblue tetrazolium (NBT) tests that were done 16-24 h after the transfusion showed 14-46% dye reduction. Two of the three patients survived the infection. Granulocyte transfusions from G-CSF and dexamethasone stimulated donors could be a choice of treatment in chronic granulomatous disease patients, especially with disseminated invasive Aspergillosis.

Abstract
Reactive oxygen species (ROS) production by phagocytic leukocytes is a critical factor in immunity against microorganisms. Human neonates are susceptible to overwhelming infections, for which abnormal granulocyte function may play an important role. In this study, we aimed to identify a convenient and quantitative method to measure ROS production by human granulocytes after cellular activation. We first compared the results of a flow cytometric assay with 2',7'-dichlorodihydrofluorescein diacetate (H2DCF) probe or dihydrorhodamine-123 (DHR123) and an enhanced chemiluminescence test using granulocytes from a patient with chronic granulomatous disease and normal granulocytes stimulated with different concentrations of phorbol myristate-13-acetate. Peripheral blood granulocyte respiratory burst ability from 37 newborn babies with different gestational ages was then quantified using flow cytometric assay with H2DCF probe. We found that flow cytometric assay of ROS production is sensitive and correlates with chemiluminescence measurements. The results showed that activated granulocytes from neonates with higher birth body weights and more advanced gestational ages tend to have higher levels of ROS production in respiratory burst (p=0.0042 and 0.063, respectively). This study demonstrates that flow cytometry is suitable for detecting the functional defects in granulocyte ROS production in human neonates of different gestational age.

Abstract
Abstract
The analysis of specific gene defects in disorders of phagocyte function has shed light on important aspects of the innate immune response. Each disorder has distinctive features in the clinical presentation and characteristic microbial pathogens. Chronic granulomatous disease has been extensively studied both in patient series and in mouse models. New insights continue to be obtained regarding the role of the nicotinamide dinucleotide phosphate (NADPH) oxidase and related enzymes in host defense and other aspects of the inflammatory response, as well as optimal management of this disorder. Approaches based on hematopoietic stem cell transplantation and gene therapy offer promise for the future, but are still under investigation. Also briefly summarized are updates on newly described leukocyte adhesion defects and on inherited susceptibility to mycobacterial infection due to defects in interleukin (IL)-12 and interferon-γ pathways.

Abstract
Beside the inability to produce superoxide ions, neutrophils (PMN) from chronic granulomatous disease (CGD) patients show other functional defects, e.g. abnormal membrane potential reactions. We observed that PMN from a female CGD carrier, with a discrete mutation in one allele of the pg91(phox) gene and exhibiting extreme lyonization, showed a consistently and remarkably delayed PMN cytosolic calcium response to the tripeptide fMLP or leukotriene B4 (LTB4). In keeping with results from other CGD patients, membrane potential changes were abnormal, whereas chemotaxis and adherence was normal. Since phospholipase D-generated metabolites are important for calcium transients we examined the generation of phosphatidic acid, but found that to be normal. A male CGD patient with pg91(phox) deficiency exhibited a trend toward prolongation of this calcium response, whereas two other CGD patients (one with p47 and one with 67(phox) deficiencies) had normal calcium transients. Thus, our finding points to a defect of the stimulus response coupling for fMLP and LTB4, which is supposed to be characteristic for this patient or a subset of CGD patients.

Abstract
BACKGROUND CD40 ligand (CD40L) expression on platelets is mediated by agonists, but the underlying mechanism is still unclear. METHODS AND RESULTS CD40L expression was measured in platelets from healthy subjects both with and without the addition of antioxidants or a phospholipase A2 (PLA2) inhibitor and in platelets from 2 patients with an inherited deficiency of gp91phox. Immunoprecipitation analysis was also performed to determine whether normal platelets showed gp91phox expression. Unlike catalase and mannitol, superoxide dismutase inhibited agonist-induced platelet CD40L expression in healthy subjects. Immunoprecipitation analysis also showed that platelets from healthy subjects expressed gp91phox. In 2 male patients with inherited gp91phox deficiency, collagen-, thrombin-, and arachidonic acid-stimulated platelets showed an almost complete absence of superoxide anion (O(2)(-)) and CD40L expression. Incubation of platelets from healthy subjects with a PLA2 inhibitor almost completely prevented agonist-induced O(2)(-) and CD40L expression. CONCLUSIONS These data provide the first evidence that platelet CD40L expression occurs via arachidonic acid-mediated gp91phox activation.

Abstract
Reactive oxygen intermediates (ROI) generated in the respiratory burst reaction are crucial for the killing of bacteria and fungi in phagocytes. The key enzyme for the respiratory burst reaction is the NADPH oxidase. Reactive oxygen intermediates have additionally been proposed to be of general importance for the expression of FAS and soluble FAS ligand (sFASL) and the subsequent induction of apoptosis. This conclusion has been drawn from the observation that neutrophils with an inborn lack of the NADPH oxidase as well as cell lines and monocytes with artificially blocked NADPH oxidase exhibit impaired apoptosis. Being one of the few centers caring for patients with chronic granulomatous disease (CGD) who exhibit an inborn lack of NADPH oxidase, we had the unique opportunity to determine the role of the NADPH oxidase for apoptosis in monocytes with otherwise unmanipulated cells of these patients (CGD monocytes). We compared the expression of FAS on monocytes and the concentration of sFASL in the supernatant between CGD monocytes and healthy donors undergoing spontaneous apoptosis. Neither the expression of FAS nor the concentration of sFASL was decreased in CGD monocytes. We further compared spontaneous apoptosis and apoptosis occurring after the phagocytosis of Staphylococcus aureus in CGD monocytes to monocytes of healthy controls. In these experiments we could not determine any significant impairment of apoptosis in CGD monocytes. Our data indicate for the first time that in an unmanipulated human model a functional NADPH oxidase is not crucial for the apoptosis of monocytes and disprove a general role of ROI for the induction of apoptosis in phagocytes.

Abstract
The release of tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and IL-10 upon stimulation with non-viable conidia and hyphal fragments from Aspergillus fumigatus was investigated in an ex vivo whole-blood model. In healthy volunteers, high numbers of conidia (between 10(6) and 3 x 10(8)/ml) induced a moderate release of TNF-alpha and IL-6. Hyphal fragments (2.5 x 10(5)/ml) were more potent in stimulating the release of these pro-inflammatory cytokines. Although some IL-10 release was observed upon stimulation with either conidia or hyphal fragments, it was not significantly different from that in unstimulated controls. In comparison, in whole blood obtained from 4 patients with chronic granulomatous disease (CGD), a high release of pro-inflammatory cytokines together with a significantly higher IL-10 release than in the healthy controls was seen after stimulation with A. fumigatus. In conclusion, A. fumigatus can trigger the release of pro-inflammatory cytokines in a human whole-blood system, which is likely to be central to the activation of antifungal defence mechanisms. In contrast, A. fumigatus stimulates a higher release of anti-inflammatory cytokines in CGD patients, which may suggest that a dysregulation between pro- and anti-inflammatory cytokines contributes to the increased susceptibility to invasive aspergillosis in this patient group.

Abstract
Chronic granulomatous disease (CGD) is an inherited disease characterized by severe and recurrent bacterial and fungal infections. Phagocytic cells of CGD patients are unable to produce superoxide anion, and their efficiency in bacterial killing is significantly impaired. In these patients, the prophylactic and therapeutic validity of a long-term use of trimethoprim-sulfamethoxazole (TMP-SMX) has been well established. However a role of nitric oxide (NO) produced by phagocytic cells from CGD patients is unknown, and the mechanism of TMP-SMX in CGD is unclear. We have directly measured NO production in whole human blood by using 4,5-diaminofluorescein as a novel fluorescent indicator for intracellular NO. Intracellular NO production of gated neutrophils increased time dependently when stimulated by lipopolysaccharide (LPS) and calcium ionophore. Although all polymorphonuclear leukocyte (PMN) specimens from patients with CGD failed to generate hydrogen peroxide, NO production by CGD PMNs was significantly increased compared with that of control PMNs (p<0.05). TMP-SMX with LPS significantly increased compared with LPS-stimulated samples at clinical (n=5, p<0.05) and 10-fold clinical concentrations (n=5, p<0.01). TMP-SMX with LPS in CGD PMNs significantly increased the production of NO in comparison with the LPS stimulation at 10-fold clinical concentrations (n=5, p<0.05). In conclusion, our data indicate the possibility that NO production by neutrophils from patients with CGD treated with TMP-SMX has a role of bactericidal activity instead of O(2)(-) in host defense mechanism.

Abstract
As a single-gene defect in phagocytes, the X-linked form of chronic granulomatous disease (X-CGD) is a disorder potentially amenable to gene therapy by transfer of a functional copy of the gp91(phox) gene into hematopoietic stem cells (HSC). Although antimicrobial agents and interferon-gamma (IFN-gamma) have significantly improved its prognosis, CGD is still associated with high morbidity and mortality. The disease can be cured by bone marrow transplantation (BMT); however, BMT in CGD has been associated with unacceptably high rates of morbidity, mortality, and graft failure, except in very selected cases in which an HLA-identical donor is available. Prerequisites for a clinical gene therapy of CGD are an efficient mobilization of peripheral blood stem cells (PBSC) as well as the preservation of their viability and hematopoietic potential following transduction and ex vivo culture. We show that (i) mobilization and collection of CD34(+) cells after a 4-week IFN-gamma-free period by G-CSF results in sufficient numbers of cells for transplantation; (ii) the quality of collected stem cells is not altered in comparison to cells obtained from healthy volunteers as assessed by long-term culture initiating cells (LTC-IC) and progenitor cell expansion; (iii) retroviral transfer of the gp91(phox) gene under defined, serum-free conditions leads to high and stable reconstitution of the respiratory burst activity in X-CGD neutrophils derived from transduced CD34(+) progenitor and LTC-IC. Withdrawal of IFN-gamma in CGD patients may improve mobilization of CD34(+) stem cells by G-CSF. The gene transfer conditions established here are applicable to a clinical approach for gene therapy of X-CGD.

Abstract
We report here two atypical cases of X-linked CGD patients (first cousins) in which cytochrome b(558) is present at a normal level but is not functional (X91+). The mutations were localized by single-strand conformational polymorphism of reverse transcriptase-polymerase chain reaction amplified fragments and then identified by sequence analysis. They consisted in two base substitutions (C919 to A and C923 to G), changing His303 to Asn and Pro304 to Arg in the cytosolic gp91phox C-terminal tail. Mismatched polymerase chain reaction and genomic DNA sequencing showed that mothers had both wild-type and mutated alleles, confirming that this case was transmitted in an X-linked fashion. A normal amount of FAD was found in neutrophil membranes, both in the X91+ patients and their parents. Epstein-Barr virus-transformed B lymphocytes from the X91+ patients acidified normally upon stimulation with arachidonic acid, indicating that the mutated gp91phox still functioned as a proton channel. A cell-free translocation assay demonstrated that the association of the cytosolic factors p47phox and p67phox with the membrane fraction was strongly disrupted. We concluded that residues 303 and 304 are crucial for the stable assembly of the NADPH oxidase complex and for electron transfer, but not for its proton channel activity.

Abstract
Chronic granulomatous disease (CGD) is an inherited immunodeficiency disease caused by defects in leukocyte NADPH oxidase. Various inherited defects in one of the membrane-bound components of NADPH oxidase, gp91-phox, cause X-linked (X91) CGD. Analysis of three patients with X91 CGD revealed that different mechanisms of molecular quality control lead to the common phenotype of absence of mature membrane-bound NADPH oxidase complex in leukocytes. In the first patient, aberrant intron splicing created a premature stop codon. However, the mutant mRNA was degraded prematurely, which prevented the production of truncated protein. In the second patient, a frameshift mutation with the potential to generate a gp91-phox polypeptide, with an aberrant and elongated C-terminus, led to barely detectable levels of gp91-phox, even though the reported functional domains of the protein appeared unaffected. In the third patient, a point mutation created a single amino acid change in the predicted FAD-binding site of gp91-phox. Although gp91-phox was detectable with Western blotting, no cytochrome b(558) was expressed on the cell surface. These analyses showed that molecular quality control machinery plays an important role in the pathogenesis of CGD, not only in the X910 but also in the X91- form of this X-linked disease.

Abstract
Neutrophils undergo rapid spontaneous apoptosis. Multiple antiapoptotic stimuli can inhibit this process via activation of the Akt pathway. However, despite no such effect singly, combined anti- and proapoptotic stimuli inhibit Akt activity, leaving the cells susceptible to accelerated apoptosis. The blockade of Akt activation depended on reduced phosphoinositide 3,4,5-trisphosphate levels but not decreased phosphatidylinositol 3-kinase activity, thus implicating the involvement of an inositol phosphatase. Evidence for SHIP involvement was provided by SHIP localization to membrane receptors and subsequent activation along with the observed inability of SHIP -/- neutrophils to exhibit enhanced apoptosis with the stimulus combination. Activation of SHIP was found to depend on Lyn activation, and this, in turn, required NADPH oxidase. Neutrophils from chronic granulomatous disease patients and Lyn -/- mice no longer responded to the combined stimuli. Thus, we propose a role for oxidants and Lyn in SHIP regulation and suggest a novel mechanism for regulating neutrophil apoptosis.

Abstract
The effects of 6-formylpterin on the impaired bactericidal activity of human neutrophils were examined ex vivo. When neutrophils isolated from fresh blood were incubated with 6-formylpterin, the intracellular production of hydrogen peroxide (H(2)O(2)) occurred. The H(2)O(2) generation by 6-formylpterin in neutrophils occurred in the presence of diphenyleneiodonium (DPI), an inhibitor of NADPH-oxidase. When neutrophils were incubated with DPI, the killing rate of catalase-positive bacteria, Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), significantly decreased. This impaired bactericidal activity of the DPI-treated neutrophils was a mimic for chronic granulomatous disease (CGD). However, the killing rate of the DPI-treated neutrophils against E. coli and S. aureus significantly increased when 6-formylpterin was administered. Since 6-formylpterin intracellularly generates H(2)O(2) independent from the NADPH-oxidase, it was considered to improve the impaired bactericidal activity of the DPI-treated neutrophils. The use of 6-formylpterin may serve as an option of therapy for CGD.

Abstract
Chronic granulomatous disease (CGD) is an inherited primary immunodeficiency characterized by phagocytes devoid of a functioning nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. The failure of CGD phagocytes to produce reactive oxygen species (ROS) results in a marked increase in the susceptibility of affected patients to life-threatening bacterial and fungal infections. This study investigated whether loading of CGD phagocytes with glucose oxidase (GO)-containing liposomes (GOLs) could restore cellular production of bactericidal ROS (eg, H2O2 and HOCl) in vitro. Results indicate that GO encapsulated in liposomes enabled NADPH oxidase-deficient phagocytes to use H2O2 for the production of highly bactericidal HOCl. The intracellular colocalization of bacteria and liposomes (or liposome-derived ferritin) was demonstrated by confocal laser microscopy and electron microscopy. After uptake of GOLs (approximately 0.2 U/mL at 1 mM total lipid concentration, size approximately 180 nm), CGD granulocytes produced HOCl levels comparable to those of normal phagocytes. Remarkably, after treatment with GOLs, CGD phagocytes killed Staphylococcus aureus as efficiently as normal granulocytes. Moreover, treated cells retained sufficient motility toward chemotactic stimuli as measured by chemotaxis assay. Side effects were evaluated by measuring the H2O2 concentrations and the production of methemoglobin in whole blood. These studies revealed that H2O2 produced by GOLs was degraded immediately by the antioxidative capacity of whole blood. Elevated methemoglobin levels were observed only after application of extremely high amounts of GOLs (2 U/mL). In summary, the application of negatively charged GOLs might provide a novel effective approach in the treatment of patients with CGD at high risk for life-threatening infections.

Abstract
The Fc gamma receptor type IIIb (CD16) is highly expressed on human neutrophils and is found in a soluble form in plasma and in other body fluids. Upon activation of neutrophils in vitro, Fc gamma RIIIb is shed from the cell surface by proteolytic cleavage. We have now investigated the effect of metalloproteinase inhibitors and a serine proteinase inhibitor on the shedding of Fc gamma RIIIb induced by phorbol 12-myristate 13-acetate (PMA) or cytochalasin B (cyto B) + N-formyl-methionyl-leucyl-phenylalanine (fMLP). Metalloproteinase inhibitors blocked to a large extent PMA-induced, but not cyto B + fMLP-induced shedding of Fc gamma RIIIb. Inhibition of members of the ADAM (a disintegrin and metalloproteinase) family appeared most efficient. In contrast, the serine protease inhibitor N-methoxysuccinyl-alanine-alanine-proline-valine-chloromethylketone (MeOsuc-AAPV-CMK) largely blocked cyto B + fMLP-induced, but not PMA-induced shedding of Fc gamma RIIIb. Metalloproteinase inhibitors in combination with the serine proteinase inhibitor resulted in full inhibition of Fc gamma RIIIb shedding induced by either PMA or cyto B + fMLP. The shedding of Fc gamma RIIIb that accompanied apoptosis was inhibited by 60% in the presence of inhibitors of metalloproteinases but was insensitive to inhibition of serine proteinases. These results show that distinct types of proteolytic enzyme are involved in the stimulus-induced shedding of Fc gamma RIIIb from human neutrophils and suggest that these proteinases may become differentially activated under various physiological or pathological conditions.

Abstract
Helicobacter pylori neutrophil-activating protein (HP-NAP) is a virulence factor that activates phagocytic NADPH-oxidase. The effect of HP-NAP on the production of tissue factor (TF), plasminogen activator inhibitor-2 (PAI-2), and urokinase-type plasminogen activator (u-PA) by human blood mononuclear cells (MNC) was evaluated by using functional and immunological assays and mRNA analysis. HP-NAP induced time- and dose-dependent increases in TF and PAI-2, with a maximal effect at 300 nmol/L (>15-fold increase in antigens). No changes in u-PA were observed. When whole bacteria were used, an H. pylori mutant lacking HP-NAP was significantly less active than the wild-type strain. MNC from a patient with chronic granulomatous disease behaved as do normal cells, which indicates that HP-NAP effects can occur independently of NADPH-oxidase. HP-NAP, by inducing the coordinate expression of cell procoagulant and antifibrinolytic activities, might favor fibrin deposition and contribute to the inflammatory reaction of gastric mucosa elicited by H. pylori.

Abstract
A fetus diagnosed with X-linked chronic granulomatous disease was transplanted with Thy-1(+)CD34(+) cells of paternal origin. The transplant was performed at 14 weeks gestation by ultrasound guided injection into the peritoneal cavity. The fetus was delivered at 38 weeks gestation after an otherwise uneventful pregnancy. Umbilical cord blood was collected and used to determine the level of peripheral blood chimerism as well as levels of functional engrafted cells. Flow cytometry was used to detect donor leukocytes identified as HLA-A2(-)B7(+) cells, whereas recipient cells were identified as HLA-A2(+)B7(-) cells. No evidence of donor cell engraftment above a level of 0.01% was found. PCR was used to detect HLA-DRB1*15(+) donor cells among the recipient's HLA-DRB1*15(-) cells, but no engraftment was seen with a sensitivity of 1:1000. The presence of functional, donor-derived neutrophils was assessed by flow cytometry using two different fluorescent dyes that measure reactive oxygen species generated by the phagocyte NADPH oxidase. No evidence of paternal-derived functional neutrophils above a level of 0.15% was observed. Peripheral blood and bone marrow samples were collected at 6 months of age. Neither sample showed engraftment by HLA typing using both flow cytometry and PCR. Functional phagocytes were also not observed. Furthermore, no indication of immunological tolerance specific for the donor cells was indicated by a mixed lymphocyte reaction assay performed at 6 months of age. While there appears to be no engraftment of the donor stem cells, the transplant caused no harm to the fetus and the child was healthy at 6 months of age. Analyses of fetal tissues, obtained from elective abortions, revealed that CD3(+) T cells and CD56(+)CD3(-) NK cells are present in the liver at 8 weeks gestation and in the blood by 9 weeks gestation. The presence of these lymphocytes may contribute to the lack of donor cell engraftment in the human fetus.

Abstract
The relationship between activation of NADPH-oxidase, alterations in membrane potential and triggering of Ca2+ fluxes in human phagocytes has been investigated using neutrophils from four subjects with chronic granulomatous disease (CGD). Cytosolic Ca2+ and membrane potential were measured by spectrofluorimetry, and net efflux and influx of Ca2+ by radiometric procedures. Exposure of normal neutrophils to the chemotactic tripeptide, N-formyl-L-methionyl-L-leucyl-L-phenylalanine (FMLP; 1 microM) was accompanied by an abrupt increase in cytosolic Ca2+ coincident with membrane depolarization and efflux of the cation. These events terminated at around 30 s after the addition of FMLP and were followed by membrane repolarization and store-operated influx of Ca2+, both of which were superimposable and complete after about 5 min. Activation of CGD neutrophils was also accompanied by an increase in cytosolic Ca2+, which, in spite of an efficient efflux response, was prolonged in relation to that observed in normal cells. This prolonged increase in cytosolic Ca2+ in activated CGD neutrophils occurred in the setting of trivial membrane depolarization and accelerated influx of Ca2+, and was associated with hyperactivity of the cells according to excessive release of elastase and increased activity of phospholipase A2. Treatment of CGD neutrophils with the type 4 phosphodiesterase inhibitor, rolipram (1 microM) restored Ca2+ homeostasis and attenuated the increase in elastase release. These findings support the involvement of NADPH-oxidase in regulating membrane potential and Ca2+ influx in activated neutrophils, and may explain the disordered inflammatory responses and granuloma formation which are characteristic of CGD.

Abstract
BACKGROUND Kx is lacking in the RBCs of patients with the McLeod syndrome. This condition is sometimes associated with chronic granulomatous disease (CGD). If given allogeneic RBCs, CGD patients with the McLeod phenotype may produce anti-Kx and anti-Km, and only phenotypically matched McLeod blood would be compatible. McLeod phenotype persons without CGD have made anti-Km but not anti-Kx (2 examples), and thus both McLeod and K(O) blood would be compatible. CASE REPORT RBCs from a transfused patient with the McLeod phenotype but not with CGD (non-CGD McLeod) were typed for the Kell blood group antigens, and the plasma was analyzed for the presence of antibody by agglutination. The molecular basis was determined by analyzing for XK protein on RBC membranes by Western immunoblotting, by sequencing the XK gene, and by RFLP. RESULTS The RBCs did not react with anti-Kx + anti-Km and showed weakening of Kell system antigens. The patient's plasma reacted moderately (2+) with RBCs of common Kell type and strongly (4+) with K(O) RBCs and RBCs of common Kell type treated with dithiothreitol, and did not react with McLeod RBCs. XK protein was absent from the RBC membranes. The XK gene had a point mutation in the donor splice site of intron 1 (G>C). CONCLUSION This is the first report describing the molecular alteration in a non-CGD McLeod patient who has made anti-Kx. The immune response of people with the McLeod phenotype can vary, and K(O) blood may not always be compatible.

Abstract
X-linked chronic granulomatous disease (CGD) derives from defects in the CYBB gene, which encodes the gp91-phox component of NADPH oxidase. We studied the molecular basis of the disease in a kindred with variant CGD, due to a single base substitution at the sixth position of CYBB first intron. The patients' phagocytes have been shown previously to greatly increase superoxide release in response to interferon-gamma (IFN-gamma) in vitro and in vivo. We examined CYBB gene expression in an Epstein-Barr virus (EBV)-transformed B-cell line from 1 patient in this kindred. These cells showed markedly decreased levels of CYBB transcripts in total RNA (5% of normal) and nuclear RNA (1.4% of normal), despite equal CYBB transcription rates in the CGD and control cells. Incubation with IFN-gamma produced a 3-fold increase in CYBB total messenger RNA (mRNA) levels in the patient's cells, and decreased nuclear transcripts to undetectable levels. Reverse transcriptase-polymerase chain reaction analysis of RNA splicing revealed a preponderance of unspliced CYBB transcripts in the patient's nuclear RNA. In vitro incubation with IFN-gamma increased by 40% the ratio of spliced relative to unspliced CYBB mRNA in nuclei from the CGD B-cell line. Total RNA harvested from the same patient's monocytes, on and off therapy with IFN-gamma, showed a similar improvement in splicing. We conclude that IFN-gamma partially corrects a nuclear processing defect due to the intronic mutation in the CYBB gene in this kindred, most likely by augmentation of nuclear export of normal transcripts, and improvement in the fidelity of splicing at the first intron.

Abstract
We report a rare case of a male patient without known immunodeficiency consecutively diagnosed with visceral leishmaniasis, brain abscess and cavitating pneumonia in the 3rd decade of life. Chronic granulomatous disease (CGD) was diagnosed by a nitroblue tetrazolium test. A p47-phox mutation of the NADPH oxidase of the leukocytes was suspected by immunoblotting and confirmed by DNA analysis. The patient was homozygous for this mutation while his mother and sister were heterozygous asymptomatic carriers. After the CGD diagnosis the patient started a chronic prophylactic regimen with subcutaneous interferon-gamma (0.05 mg/m2 of body surface/three times a week), and oral trimethoprim-sulfamethoxazole and itraconazole (both at 5 mg/kg/day) with no subsequent infections after 12 months of follow-up.

Abstract
The superoxide-forming nicotinamide adenine dinucleotide phosphate reduced (NADPH) oxidase of human phagocytes comprises membrane-bound and cytosolic proteins, which, upon cell activation, assemble on the plasma membrane to form the active enzyme. Patients with chronic granulomatous disease (CGD) are defective in one of the phagocyte oxidase (phox) components, p47-phox or p67-phox, which reside in the cytosol of resting phagocytes, or gp91-phox or p22-phox, which constitute the membrane-bound cytochrome b(558). In four X-linked CGD patients we have identified novel missense mutations in CYBB, the gene encoding gp91-phox. These mutations were associated with normal amounts of nonfunctional cytochrome b(558) in the patients' neutrophils. In phorbol-myristate-stimulated neutrophils and in a cell-free translocation assay with neutrophil membranes and cytosol, the association of p47-phox and p67-phox with the membrane fraction of the cells with Cys369-->Arg, Gly408-->Glu, and Glu568--> Lys substitutions was strongly disturbed. Only a Thr341-->Lys substitution, residing in a region of gp91-phox involved in flavin adenine dinucleotide (FAD) binding, supported a normal translocation. Thus, the introduction or reversal of charge at residues 369, 408, and 568 in gp91-phox destroys the correct binding of p47-phox and p67-phox to cytochrome b(558). Based on mutagenesis studies of structurally related flavin-dependent oxidoreductases, we propose that the Thr341-->Lys substitution results in impaired hydride transfer from NADPH to FAD. Because we found no electron transfer in solubilized neutrophil plasma membranes from any of the four patients, we conclude that all four amino acid replacements are critical for electron transfer. Apparently, an intimate relation exists between domains of gp91-phox involved in electron transfer and in p47/p67-phox binding. (Blood. 2000;95:666-673)

Abstract
Chronic granulomatous disease (CGD) is a group of inherited disorders in which phagocytes are unable to generate superoxide (O(2)(-)) due to genetic defects in any 1 of 4 essential NADPH oxidase components. Mutations in the X-linked gene for gp91(phox), the large subunit of the flavocytochrome b(558) heterodimer, account for the majority of CGD. An X-CGD patient in which a splice junction mutation results in an in-frame deletion of 30 nucleotides encoding amino acids 488 to 497 of gp91(phox) (delta488-497 gp91(phox)) has previously been reported. In this study, we generated myeloid PLB-985 cells expressing the mutant triangle delta488-497 gp91(phox) to further characterize its functional properties. These cells mimicked the phenotype of the patient's neutrophils with normal expression of a nonfunctional delta488-497 gp91(phox) flavocytochrome. Translocation of p47(phox) and p67(phox) to delta488-497 gp91(phox) PLB-985 plasma membranes was not affected, as determined both in activated intact cells and in the cell-free system. Furthermore, a synthetic peptide corresponding to residues 488-497 of gp91(phox) was relatively ineffective in inhibiting O(2)(-) production in the cell-free oxidase assay (IC50, approximately 500 micromol/L), suggesting that residues 488-497 of gp91(phox) are not directly involved in oxidase assembly. Mutant delta488-497 gp91(phox) flavocytochrome failed to support iodonitrotetrazolium (INT) reduction, showing a disruption of electron transfer from NADPH to the FAD center of gp91(phox). However, the FAD binding capacity of the mutant flavocytochrome was normal, as measured by equilibrium dialysis. Taken together, these results suggest that the delta488-497 deletion in gp91(phox) disrupts electron transfer to FAD, either due to a defect in NADPH binding or to impaired delivery of electrons from NADPH.

Abstract
Chronic granulomatous disease (CGD) is a rare inherited disorder of phagocytes in which defective production of microbicidal oxidants leads to severe recurrent infections. CGD is caused by mutations in any of 4 genes encoding components of nicotinamide adenine dinucleotide phosphate (reduced form; NADPH) oxidase, the multisubunit enzyme that produces the precursor of these oxidants, superoxide. Approximately 5% of CGD patients have an autosomal recessive form of disease caused by a severe deficiency of p67-phox, a 526-amino acid subunit of the oxidase that appears to regulate electron transport within the enzyme. Here we report the biochemical and molecular characterization of 6 unrelated kindreds with p67-phox deficiency. These studies show that, as in gp91-phox and p22-phox deficiencies, the p67-phox CGD patients show a high degree of heterogeneity in the genetic defects that underlie their disease. Five different mutant alleles were identified: (1) a nonsense mutation in exon 4 (C(304) --> T); (2) a 5-nucleotide (nt) deletion in exon 13 (nts 1169-1173); (3) a splice mutation in the first nucleotide of intron 4 (G --> A); (4) a deletion of 1 nt in exon 9 (A(728)); and (5) a 9-nt in-frame deletion in exon 2 (nts 55-63). The splice mutation was seen in 3 unrelated kindreds, while the 5-nt deletion was seen in 2 apparently unrelated families (both of Palestinian origin). Homozygosity was present in 4 of the kindreds, 2 of which had consanguineous parentage. In the isolated neutrophils of each of the affected patients in the 6 kindreds, there was no measurable respiratory burst activity and no p67-phox protein detected by immunoblot analysis. The level of 67-phox mRNA was less than 10% of normal in the mononuclear leukocytes from 3 of the 4 patients analyzed by Northern blot studies. Thus, this heterogeneous group of mutations in p67-phox all lead to marked instability of mRNA or protein (or both) that results in the complete loss of NADPH oxidase activity.

Abstract
Chronic granulomatous disease is a rare inherited disorder caused by non-existent or severely decreased phagocyte superoxide production that results in a severe defect in host defense and consequent predisposition to microbial infection. The enzyme responsible for superoxide production, NADPH oxidase, involves at least five components. An absence of, or a defect in, any one of four of these proteins (p47(phox), p67(phox), p22(phox) and gp91(phox)) gives rise to the known types of chronic granulomatous disease. The most common form of inheritance is X-linked and is due to mutations in the CYBB gene that encodes gp91(phox), the large subunit of flavocytochrome b, the terminal electron donor of the oxidase. We have recently reported a large number of mutations in this gene revealing a broad range of defects, including large and small deletions, and frameshift, nonsense, missense, splice region and regulatory region mutations. Here we report a patient who has an unusual type of mutation that results in the generation of a 'pseudo-exon' in the gp91(phox) mRNA and an unexpected pattern of splicing.

Abstract
Mycobacterium bovis BCG is an opportunistic agent that may be responsible for disseminated disease in immunocompromised individuals. Under physiological conditions, macrophages are the natural hosts and final killers of BCG. In the context of inherited or acquired immune disorders underlying disseminated BCG infections, macrophages fail to eradicate BCG or even to restrict its intracellular growth. The direct contribution of macrophages, in this setting of impaired BCG destruction, probably depends on the type of underlying immune deficiency and remains to be experimentally investigated. As an initial approach, we document here the fate of BCG within human monocytes and human monocyte-derived macrophages (MDMs) cultured in commercially available serum-free medium (M-SFM). This medium was used to avoid potential problems associated with human or animal serum-supplemented medium. We show here that both monocytes and MDMs cultured in M-SFM display the morphological features and functional activities expected for such cells. We also show that after an initial phase of intracellular destruction, BCG grow within infected monocytes-macrophages, as shown by colony forming unit (CFU) counts and Ziehl-Nielsen staining. By an electron microscopic analysis, we show that the BCG always reside within phagosomes and that 24-h postinfection many phagosomes stain for the hydrolytic enzyme acid phosphatase. Finally, we compare bacterial growth in vitro within phagocytes from healthy individuals and patients with chronic granulomatous disease (CGD), an inheritable condition associated with disseminated BCG infection in vivo. No destruction of intracellular BCG was achieved by the patients cells, revealing the essential mycobactericidal role of the respiratory burst in human phagocytes. Investigations of BCG growth within MDM cultured in M-SFM from patients with other conditions which predispose to clinical BCG infection is therefore warranted.

Abstract
Optimal microbicidal activity of polymorphonuclear leukocytes (PMNs) requires recruitment of a functional nicotinamide adenine dinucleotide phosphate (NADPH) oxidase to the phagosome. In this study, we used a synchronized phagocytosis assay and immunofluorescence microscopy (IFM) to examine the association of cytosolic NADPH oxidase subunits with phagosomes containing opsonized zymosan (OpZ). Ingestion of OpZ began within 30 seconds of particle binding and forming phagosomes were enriched for both F-actin and the actin-binding protein p57. NADPH oxidase subunits p47phox and p67phox were also recruited to forming phagosomes and were retained on mature phagosomes for at least 15 minutes. Colocalization of F-actin, p57, and p47phox on phagosomes was confirmed by immunoblotting. Translocation of p67phox, but not p57, to forming phagosomes was deficient in PMNs lacking p47phox. Surprisingly, we found that in PMNs from six individuals with X-linked chronic granulomatous disease (CGD), p47phox and p67phox accumulated in the periphagosomal area during ingestion of OpZ. However, in marked contrast to normal PMNs, p47phox and p67phox were shed from nascent phagosomes along with F-actin and p57 once OpZ was internalized (approximately 5 minutes). These data support a model in which flavocytochrome b is required for stable membrane binding of p47phox and p67phox, but not their association with the cytoskeleton or transport to the cell periphery.

Abstract
Treatment with gamma-interferon (IFN-gamma) is associated with reduced frequency and severity of infections in chronic granulomatous disease (CGD), but the mechanism is unknown. Since the inducible nitric oxide (NO) synthase can be amplified by IFN-gamma in murine macrophages, for example, we hypothesized that IFN-gamma might modulate NO release from polymorphonuclear neutrophils (PMNs) in patients with CGD. Eight patients with CGD and eight healthy controls were studied. Each patient was given either 50 or 100 microg of IFN-gamma per m2 on two consecutive days. The production of NO from N-formyl-methionyl-leucyl-phenylalanine (fMLP)-stimulated PMNs was assessed as the NG-monomethyl-L-arginine-inhibitable oxidation of oxyhemoglobin to methemoglobin in the presence of catalase and superoxide dismutase. Prior to IFN-gamma treatment, the PMNs from CGD patients produced 372 +/- 27 (mean +/- standard error of the mean) pmol of NO/10(6) PMNs at 45 min, while the control PMNs produced 343 +/- 44 pmol. On day 1 after IFN-gamma treatment, NO production increased to 132% +/- 25% of that for controls, and on day 3 it reached 360% +/- 37% (P < 0.001) of that for controls. On day 8, the values still remained higher, 280% +/- 78% more than the control values. Likewise, the bactericidal capacity of PMNs increased on day 3. The present data show that IFN-gamma treatment of CGD patients is associated with an increased production of NO from PMNs when activated by fMLP. Since these PMNs lack the capacity to produce superoxide anions, it is conceivable that this increase in NO release could be instrumental in augmenting host defense.

Abstract
BACKGROUND Chronic granulomatous disease (CGD) is an inherited disease characterized clinically by severe recurrent bacterial infections from infancy. This disease is a disorder of the formation of superoxide (O2-) by the neutrophil NADPH oxidase system, mostly due to defects in cytochrome b558 (cyt b558), which is one of the oxidase components. Diagnosis of CGD has been performed by the assay of the O2- forming activity, immunological determination of defects in the oxidase components, and or spectrophotometry of cyt b558. However, spectrophotometric analysis of the b-type heme is difficult with small amounts of blood from infant CGD patients, as the limited amounts of neutrophils are contaminated with a relatively high ratio of hemoglobin (Hb) that interferes with the heme spectrum of cyt b558. This report presents an accurate method for the spectrophotometric analysis of cyt b558 in a small amount of CGD neutrophils that were treated with CO gas in a safe procedure instead of the previously reported CO-bubbling method. METHODS AND RESULTS The difference of the reduced minus oxidized cyt b558 spectrum was measured under no interference from oxy Hb at the alpha and beta bands and differentiated as d[delta A]/d lambda (lambda = wavelength) to obtain further evidence for the defects of the cyt b558 heme spectrum. The interference from CO-insensitive met Hb was eliminated by subtracting the absorption peak at the Soret (gamma) band of the contaminating met Hb, which was estimated from the CO-treated and untreated spectra of the same, hemolyzed sample. CONCLUSIONS This spectrophotometric method is feasible for the determination of abnormality and heme content of cyt b558 with a small amount of CGD neutrophils in 10-20 mL of blood even in the presence of contaminating Hb.

Abstract
We have reported a deficiency of a 91-kDa glycoprotein component of the phagocyte NADPH oxidase (gp91(phox)) in neutrophils, monocytes, and B lymphocytes of a patient with X chromosome-linked chronic granulomatous disease. Sequence analysis of his gp91(phox) gene revealed a single-base mutation (C --> T) at position -53. Electrophoresis mobility-shift assays showed that both PU.1 and hematopoietic-associated factor 1 (HAF-1) bound to the inverted PU.1 consensus sequence centered at position -53 of the gp91(phox) promoter, and the mutation at position -53 strongly inhibited the binding of both factors. It was also indicated that a mutation at position -50 strongly inhibited PU.1 binding but hardly inhibited HAF-1 binding, and a mutation at position -56 had an opposite binding specificity for these factors. In transient expression assay using HEL cells, which express PU.1 and HAF-1, the mutations at positions -53 and -50 significantly reduced the gp91(phox) promoter activity; however, the mutation at position -56 did not affect the promoter activity. In transient cotransfection study, PU.1 dramatically activated the gp91(phox) promoter in Jurkat T cells, which originally contained HAF-1 but not PU.1. In addition, the single-base mutation (C --> T) at position -52 that was identified in a patient with chronic granulomatous disease inhibited the binding of PU.1 to the promoter. We therefore conclude that PU.1 is an essential activator for the expression of gp91(phox) gene in human neutrophils, monocytes, and B lymphocytes.
