Abstract
Inflammation drives asthma and atherosclerosis. Clinical studies suggest that asthmatic patients have a high risk of atherosclerosis. Yet this hypothesis remains uncertain, given that Th2 imbalance causes asthma whereas Th1 immunity promotes atherosclerosis. In this study, chronic allergic lung inflammation (ALI) was induced in mice by ovalbumin sensitization and challenge. Acute ALI was induced in mice by ovalbumin and aluminum sensitization and ovalbumin challenge. Atherosclerosis was produced in apolipoprotein E-deficient (Apoe(-/-)) mice with a Western diet. When chronic ALI and atherosclerosis were produced simultaneously, ALI increased atherosclerotic lesion size, lesion inflammatory cell content, elastin fragmentation, smooth muscle cell (SMC) loss, lesion cell proliferation, and apoptosis. Production of acute ALI before atherogenesis did not affect lesion size, but increased atherosclerotic lesion CD4(+) T cells, lesion SMC loss, angiogenesis, and apoptosis. Production of acute ALI after atherogenesis also did not change atherosclerotic lesion area, but increased lesion elastin fragmentation, cell proliferation, and apoptosis. In mice with chronic ALI and diet-induced atherosclerosis, daily inhalation of a mast cell inhibitor or corticosteroid significantly reduced atherosclerotic lesion T-cell and mast cell contents, SMC loss, angiogenesis, and cell proliferation and apoptosis, although these drugs did not affect lesion area, compared with those that received vehicle treatment. In conclusion, both chronic and acute ALI promote atherogenesis or aortic lesion pathology, regardless whether ALI occurred before, after, or at the same time as atherogenesis. Antiasthmatic medication can efficiently mitigate atherosclerotic lesion pathology.

Abstract
Based on demonstrated effects on functional immunity in rodent models and supportive evidence from epidemiological studies, it is apparent that developmental exposure to ligands for the aryl hydrocarbon receptor (AhR) has the potential to impair immunity in human populations. Furthermore, due to the high levels of these compounds detected in human breast milk, and the fact that they cross the placenta, it is clear that humans are exposed to AhR ligands during fetal and neonatal development. The current studies were conducted to further characterize the relationship between developmental exposure to TCDD, the most potent AhR agonist, and defects in immune function later in life. Impregnated C57Bl/6 mice were treated with 4 doses of 1 mircog/kg TCDD, given on days 0, 7, and 14 of pregnancy, and 2 days after parturition. Functional immunity was assessed by challenging the adult offspring with influenza virus. Both male and female offspring of the TCDD-treated dams demonstrated impairment of the adaptive immune response, as evidenced by suppressed numbers of T cells and IFNgamma-producing cells in the draining lymph nodes and reduced T cell recruitment to the lung. In contrast, the inflammatory response, including infection-associated pulmonary neutrophilia and IFNgamma levels, was significantly elevated in the developmentally-exposed mice. These functional defects in immunity were not correlated with defects in hematopoeisis, as immune cells in the bone marrow, spleen, and thymus were phenotypically normal in uninfected mice. These results support the idea that immune alterations that arise during development cause persistent and significant changes in immune function.

Abstract
MMP-12 plays a significant role in airway inflammation and remodeling. Increased expression and production of MMP-12 have been observed in the lungs of asthmatic patients. Compound 27 was identified as a potent and selective MMP-12 inhibitor possessing good physicochemical properties. In pharmacological studies, the compound was orally efficacious in an MMP-12 induced ear-swelling inflammation model in the mouse with a good dose response. This compound also exhibited oral efficacy in a naturally Ascaris-sensitized sheep asthma model showing significant inhibition of the late phase response to allergen challenge. This compound has been considered for further development as a treatment therapy for asthma.

Abstract
GM-CSF plays an important role in inflammation by promoting the production, activation, and survival of granulocytes and macrophages. In this study, GM-CSF knockout (GM-CSF(-/-)) mice were used to investigate the role of GM-CSF in a model of allergic airway inflammation. In allergic GM-CSF(-/-) mice, eosinophil recruitment to the airways showed a striking pattern, with eosinophils present in perivascular areas, but almost completely absent in peribronchial areas, whereas in wild-type mice, eosinophil infiltration appeared in both areas. In the GM-CSF(-/-) mice, mucus production in the airways was also reduced, and eosinophil numbers were markedly reduced in the bronchoalveolar lavage (BAL)(3) fluid. IL-5 production was reduced in the lung tissue and BAL fluid of GM-CSF(-/-) mice, but IL-4 and IL-13 production, airway hyperresponsiveness, and serum IgE levels were not affected. The presence of eosinophils in perivascular but not peribronchial regions was suggestive of a cell migration defect in the airways of GM-CSF(-/-) mice. The CCR3 agonists CCL5 (RANTES) and CCL11 (eotaxin-1) were expressed at similar levels in GM-CSF(-/-) and wild-type mice. However, IFN-gamma mRNA and protein were increased in the lung tissue and BAL fluid in GM-CSF(-/-) mice, as were mRNA levels of the IFN-gamma-inducible chemokines CXCL9 (Mig), CXCL10 (IP-10), and CXCL11 (I-Tac). Interestingly, these IFN-gamma-inducible chemokines are natural antagonists of CCR3, suggesting that their overproduction in GM-CSF(-/-) mice contributes to the lack of airway eosinophils. These findings demonstrate distinctive abnormalities to a model of allergic asthma in the absence of GM-CSF.

Abstract
IL-13 contributes to airway hyperresponsiveness, mucus secretion, inflammation, and fibrosis, suggesting that it plays a central role in asthma pathogenesis. Neutralization of IL-13 with sIL-13Ralpha2-Fc (sIL-13R) reduces allergen-induced airway responses in rodent models of respiratory disease, but its efficacy in a large animal model has not been previously reported. In this study, we determined whether two different strategies for IL-13 neutralization modified experimental asthma in sheep. Sheep with natural airway hypersensitivity to Ascaris suum antigen were treated intravenously either with sIL-13R, a strong antagonist of sheep IL-13 bioactivity in vitro, or with IMA-638 (IgG1, kappa), a humanized antibody to human IL-13. Higher doses of IMA-638 were used because, although it is a potent antagonist of human IL-13, this antibody has 20 to 30 times lower binding and neutralization activity against sheep IL-13. Control animals received human IgG of irrelevant specificity. Sheep were treated 24 h before inhalation challenge with nebulized A. suum. The effects on antigen-induced early and late bronchial responses, and antigen-induced hyperresponsiveness, were assessed. Both sIL-13R and IMA-638 provided dose-dependent inhibition of the antigen-induced late responses and airway hyperresponsiveness. The highest dose of IMA-638 also reduced the early phase response. These findings suggest that IL-13 contributes to allergen-induced airway responses in this sheep model of asthma, and that neutralization of IL-13 is an effective strategy for blocking these A. suum-induced effects.

Abstract
Gob-5 is a member of the calcium-activated chloride channel family and has been associated with allergic response in mouse models of pulmonary inflammation. Gene expression of Gob-5 has been shown to be induced in allergic airways and has been strongly associated with mucin gene regulation and goblet cell hyperplasia. We investigated the physiologic role of Gob-5 in murine models of pulmonary inflammation using mice deficient in Gob-5. After sensitization and aerosol challenge with ovalbumin (OVA), Gob-5 knockout mice exhibit significantly increased bronchoalveolar lavage (BAL) inflammation as compared with wild-type controls. The augmented inflammation in BAL consisted predominantly of neutrophils. Examination of perivascular inflammation revealed that tissue inflammation was decreased in OVA-challenged Gob-5-/- mice. OVA-challenged Gob-5 knockout mice also had decreased goblet cell hyperplasia as well as decreased mucus production. These mice also had decreased airway hypersensitivity after cholinergic provocation with methacholine. Gob-5 knockout mice were also challenged via intranasal LPS, a TLR-4 agonist. Gob-5-/- mice responded with increased neutrophilic BAL inflammation and decreased perivascular tissue inflammation as compared with wild-type controls. There was little effect on goblet cell hyperplasia and mucus production after LPS challenge. These observations reinforce findings that associate Gob-5 with goblet cell hyperplasia and mucus production in the allergic immune response, but also implicate Gob-5 in the regulation of tissue inflammation in the innate immune response.

Abstract
Both trimellitic anhydride (TMA), a small molecular weight chemical, and ovalbumin (OVA), a reference protein allergen, cause asthma with eosinophilia. To test the hypothesis that different allergens elicit symptoms of asthma via different effector pathways, gene expression was compared in lungs of Balb/c mice sensitized with either TMA or OVA, followed by intratracheal challenge with TMA conjugated to mouse serum albumin (TMA-MSA) or OVA, respectively. Sensitized animals challenged with mouse serum albumin (MSA) alone were controls. Seventy-two hours after challenge, lung eosinophil peroxidase indicated that both allergens caused the same significant change in eosinophilia. Total RNA was isolated from lung lobes of 6-8 animals in each of four treatment groups and hybridized to Affymetrix U74Av2 GeneChips. False discovery rates (q-values) were calculated from an overall F test to identify candidate genes with differences in expression for the four groups. Using a q-value cutoff of 0.1, 853 probe sets had significantly different expression across the four treatment groups. Of these 853 probe sets, 376 genes had an Experimental/Control ratio of greater than 1.2 or less than 1/1.2 for either OVA- or TMA-treated animals, and 249 of the 376 genes were uniquely up- or down-regulated for OVA or TMA (i.e., differentially expressed with the allergen). qRT-PCR analysis of selected transcripts confirmed the gene expression analysis. Increases in both arginase transcript and enzyme activity were significantly greater in OVA-induced asthma compared to TMA-induced asthma. These data suggest that pathways of arginine metabolism and the importance of nitric oxide may differ in OVA- and TMA-induced asthma.
