Abstract
BACKGROUND Sargramostim (yeast-derived, glycosylated recombinant human granulocyte-macrophage colony-stimulating factor [rhu GM-CSF]) augments innate and adaptive immune responses and accelerates hematopoietic recovery of chemotherapy-induced neutropenia. However, considerably less is known about its efficacy as adjunctive immunotherapy against invasive fungal diseases (IFDs). METHODS The clinical courses of 15 patients with pediatric malignancies and IFDs treated adjunctively with sargramostim at a single institution were analyzed in a retrospective cohort review. Further, a systematic review of published reports of rhu GM-CSF for IFDs was also conducted. RESULTS Among 65 cases, 15 were newly described pediatric patients and 50 were previously published cases of IFDs treated with rhu GM-CSF. Among the newly reported pediatric patients, IFDs were caused by Candida spp., Trichosporon sp., and molds (Aspergillus spp., Rhizopus sp., Lichtheimia sp., and Scedosporium sp). Twelve (80%) were neutropenic at baseline, and 12 (80%) were refractory to antifungal therapy. Among 12 evaluable patients, the overall response rate was 92% (8 [67%] complete responses, 3 [25%] partial responses, and 1 [8%] stable). Treatment is ongoing in the remaining 3 patients. Among 50 published cases (15 Candida spp., 13 Mucorales, 11 Aspergillus spp., 11 other organisms), 20 (40%) had baseline neutropenia and 36 (72%) were refractory to standard therapy before rhu GM-CSF administration. Consistent with responses in the newly reported patients, the overall response rate in the literature review was 82% (40 [80%] complete responses, 1 [2%] partial response, and 9 [18%] no response). CONCLUSIONS Sargramostim may be a potential adjunctive immunomodulator for selected patients with hematological malignancies and refractory IFDs.

Abstract
INTRODUCTION The incidence of invasive pulmonary aspergillosis (IPA) has increased significantly over the last two decades. Alveolar macrophages (AMs) represent the first line of pulmonary host response to Aspergillus conidia. Recognition of conidia by AMs involves Dectin-1 (CLEC7A), which is a conserved structure to combine β-glucans. The deficiency of Dectin-1 results in impaired fungal killing and uncontrolled growth of Aspergillus fumigatus. Thus, we hypothesized that high expression of Dectin-1 would enhance the host recognition and fungal killing. METHODS We set out to develop an adenoviral vector encoding full-length Dectin-1 (Ad-Dectin-1-EGFP) and then transfect it to MH-S cells. Transfect cell model was verified by using real-time RT-PCR, Western blot, flow cytometric, and confocal microscopic assays. And also, the function of Dectin-1 was explored by measuring cytokine release and killing ability during the course of A. fumigatus infection. RESULTS We constructed a recombinant adenovirus which could upregulate the expression of Dectin-1 and verified that Dectin-1 was expressed on cell membrane. The function of Dectin-1 was also demonstrated by its ability in promoting the production of cytokines and increasing the killing ability during the course of A. fumigatus infection. CONCLUSIONS An adenoviral vector was successfully applied to the production of a recombinant adenovirus encoding full-length Dectin-1, and also, its function in Aspergillus-induced innate immune response was demonstrated.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a Th2 allergic hypersensitivity lung disease due to bronchial colonization of Aspergillus fumigatus that affects 1-2% of asthmatic and 7-9% of cystic fibrosis (CF) patients. We hypothesize that genetic risk factors predispose these patients to develop ABPA. We previously reported HLA-DR2 and DR5 restriction as a risk factor for the development of ABPA. We further propose that HLA-DR restriction is necessary but not sufficient for the development of ABPA. Recently, we reported that IL-4Rα single nucleotide polymorphisms (SNP) and in particular the ile75val SNP in the IL-4 binding region is another risk factor and is associated with increased sensitivity to IL-4 stimulation. It has been reported that the combination of IL-4Rα and IL-13 SNP, ile75val/arg110gln, is associated with more severe asthma. In preliminary studies, we have observed increased frequency of this combination in ABPA asthmatic and CF patients. Another genetic risk factor reported by Brouard et al. is the -1082 GG genotype in the IL-10 promoter in CF patients for the colonization of A. fumigatus and development of ABPA. This genotype was associated with increased plasma IL-10 levels, and perhaps may be associated with increased skewing of Th2 Aspergillus responses rather than down-regulation of inflammatory responses. We hypothesize that increased sensitivity of IL-4 mediated activities secondary to polymorphisms IL-4R in conjunction of other polymorphisms such as IL-13 and IL-10 in conjunction with HLA-DR2/DR5 restriction to Aspergillus antigens in ABPA patients result in increased B-cell activity, monocyte/dendritic cell phenotype that skews Th2 responses, and skewing of Aspergillus-specific Th2 cells. This model system may be applicable to other fungi such as Alternaria and Cladosporium which is associated with increased asthma severity.

Abstract
The immunosuppressive effect of dexamethasone (DEX) on macrophage killing activity and cytokine production in response to Aspergillus fumigatus conidia is antagonized by granulocyte-macrophage colony-stimulating factor (GM-CSF). However, the intersection of signaling pathways and the molecular mechanism of this antagonism remain to be defined. We postulated that DEX inhibition of NF-kappaB was opposed by induction of IkappaB kinases (IKK) by GM-CSF + conidia stimulation, degradation of IkappaB, and release of nuclear factor kappa B (NF-kappaB). This hypothesis was tested using resident peritoneal macrophages from CD-1 mice and the murine macrophage RAW 264.7 cell line. Macrophages were unstimulated or stimulated with A. fumigatus conidia and simultaneously treated with DEX, GM-CSF or DEX + GM-CSF for 2 4 hours. IkappaB degradation in cytoplasmic extracts and translocation of NF-kappaB in nuclear extracts was measured by Western blot analysis. This showed GM-CSF reverses the immunosuppressive effect of DEX by enhancing the degradation of IkappaB and promoting the translocation of NF-kappaB to the nucleus. This would allow the production of proinflammatory cytokines by macrophages, facilitating resistance to A. fumigatus.

Abstract
In order to test the hypothesis that early postnatal exposure to dexamethasone (Dex) influences matrix metalloproteinases (MMP)-2 and -9, as well as their tissue inhibitors (TIMP-1 and -2) in the developing rat lung, newborn rats (3 litters/group) were treated with low Dex (0.1 mg/kg/day, IM), high Dex (0.5 mg/kg/day), or equivalent volumes of saline at 5 days postnatal age (P5), P6, and P7. Lung weight and lung MMP and TIMP levels were determined at sacrifice (7 days postinjection, P14; at weaning, P21; and at adolescence, P45, n = 10/group and time). Dex did not adversely affect lung weight or lung MMP-2 levels, which peaked in all groups at P21 and then fell by P45. In contrast, Dex decreased TIMP-2 at all time intervals, but achieved statistical significance only at P45. An imbalance in MMP-2/TIMP-2 ratio was noted at P21, with elevations occurring in the low and high Dex-treated groups. Lung MMP-9 levels remained comparable with controls during low Dex treatment. However, high Dex exposure resulted in elevated lung MMP-9 levels at P21 and P45. Lung TIMP-1 levels increased only with high Dex exposure at P14 and P21, whereas the lung MMP-9/TIMP-1 ratio was elevated at P21 in the high Dex group, and at P45 in both Dex-treated groups. These data provide evidence that early postnatal dexamethasone results in an imbalance between gelatinase-A and -B, and their tissue inhibitors in the developing rat lung. These changes may be responsible, in part, for some of the known maturational effects of steroids on lung structure in the newborn.

Abstract
There is substantial evidence that local production of proinflammatory cytokines are very important in host resistance to aspergillosis. Dexamethasone (DEX) down-regulates production of these cytokines by stimulated bronchoalveolar macrophages (BAM) and constitutes a risk factor for aspergillosis. Granulocyte-macrophage colony-stimulating factor (GM-CSF) antagonizes DEX suppression of antifungal activity by BAM. Here we investigated the possibility that GM-CSF could antagonize DEX down-regulation of interleukin (IL)-1alpha and tumour necrosis factor (TNF)-alpha production by stimulated BAM. Control BAM responded to increasing numbers of conidia of Aspergillus fumigatus with increasing production of IL-1 and TNF. DEX (10(-7)M) significantly suppressed IL-1 and TNF production by BAM+conidia. Although GM-CSF did not enhance IL-1 or TNF production by BAM+conidia, GM-CSF significantly antagonized DEX suppression of IL-1 cytokine production. For comparative purposes, lipopolysaccharide (LPS, 1 microg/ml) was used to stimulate BAM in experiments similar to the above. In contrast to the findings with conidia, GM-CSF enhanced the production of IL-1 (5-fold) and TNF (1.5-fold) by LPS treated BAM. DEX suppression of cytokine production by BAM+LPS was modestly but significantly antagonized by GM-CSF. Moreover, differences between regulation of IL-1 and TNF production by BAM+conidia or LPS and peritoneal macrophages (PM)+conidia or LPS were documented. Finally, the anti-inflammatory cytokine IL-10 was minimally produced by BAM + conidia or LPS, but IL-10 was produced by PM + conidia or LPS. In summary, these data indicate that the risk factor for aspergillosis associated with DEX could be lessened in the pulmonary compartment with GM-CSF. On the other hand, desired effects of DEX could be maintained in other compartments.
