Abstract
Oxidative stress is the cause and consequence of redox metabolism in various physiological and pathological conditions. Understanding the molecular pathways underlying oxidative stress and the role of antioxidants could serve as the key to helping treat associated diseases. Allergic rhinitis is a condition that deteriorates the daily function and quality of life of afflicted individuals and is associated with a high socioeconomic burden and prevalence. Recent studies have focused on the role of oxidative stress and antioxidants in allergic rhinitis. This review discusses animal and clinical studies on oxidative markers and the potential therapeutic dietary antioxidants for allergic rhinitis.

Abstract
Intense research interests have been observed in establishing PPAR gamma as a therapeutic target for diabetes. However, PPARγ is also emerging as an important therapeutic target for varied disease states other than type 2 diabetes like neurodegenerative disorders, cancer, spinal cord injury, asthma, and cardiovascular problems. Furthermore, glitazones, the synthetic thiazolidinediones, also known as insulin sensitizers, are the largely studied PPARγ agonists and the only ones approved for the treatment of type 2 diabetes. However, they are loaded with side effects like fluid retention, obesity, hepatic failure, bone fractures, and cardiac failure; which restrict their clinical application. Medicinal plants used traditionally are the sources of bioactive compounds to be used for the development of successful drugs and many structurally diverse natural molecules are already established as PPARγ agonists. These natural partial agonists when compared to full agonist synthetic thiazolidinediones led to weaker PPARγ activation with lesser side effects but are not thoroughly investigated. Their thorough characterization and elucidation of mechanistic activity might prove beneficial for counteracting diseases by modulating PPARγ activity through dietary changes. We aim to review the therapeutic significance of PPARγ for ailments other than diabetes and highlight natural molecules with potential PPARγ agonistic activity.

Abstract
Chronic obstructive pulmonary disease (COPD), characterized by chronic inflammation, is a recognized global health crisis. Sialic acid-binding immunoglobulin-like lectin 1 (siglec1 or CD169), mainly expressed in macrophages and dendritic cells, is markedly upregulated after encountering pathogens or under acute/chronic inflammation conditions. However, it is rarely reported that whether siglec1 plays a role in the development of COPD. In this study, we found that siglec1 had higher expression in the lungs from COPD rats and in peripheral blood mononuclear cells (PBMCs) from COPD patients. Knockdown of siglec1 in vivo and in vitro dramatically decreased pro-inflammatory cytokines production in pulmonary macrophages and alleviated pulmonary inflammatory responses in COPD rats as well as inactivated nuclear factor kappa B (NF-κB) signaling. In addition, we identified a new microRNA, miR-195-5p, which has never explored in COPD, was lower expressed in COPD rats and PBMC of COPD patients, and could negatively modulate siglec1 expression in macrophages. Moreover, overexpression of miR-195-5p via miR-195-5p mimics in vitro and in vivo could significantly alleviate pro-inflammatory cytokines production in pulmonary macrophages and pulmonary inflammatory responses in COPD rats. Together, our findings suggested that miR-195-5p inhibited the development of COPD via targeting siglec1, which might become a therapeutic target to improve COPD.

Abstract
Asthma is a complex inflammatory disease characterized by airway inflammation and hyperresponsiveness. The mechanisms associated with the development and progression of asthma have been widely studied in multiple populations and animal models, and these have revealed involvement of various cell types and activation of intracellular signaling pathways that result in activation of inflammatory genes. Significant contributions of Toll-like-receptors (TLRs) and transcription factors such as NF-кB, have been reported as major contributors to inflammatory pathways. These have also recently been associated with mechanisms of oxidative biology. This is of important clinical significance as the observed inefficacy of current available treatments for severe asthma is widely attributed to oxidative stress. Therefore, targeting oxidizing molecules in conjunction with inflammatory mediators and transcription factors may present a novel therapeutic strategy for asthma. In this review, we summarize TLRs and NF-кB pathways in the context of exacerbation of asthma pathogenesis and oxidative biology, and we discuss the potential use of polyphenolic flavonoid compounds, known to target these pathways and possess antioxidant activity, as potential therapeutic agents for asthma.

Abstract
BACKGROUND Evidence suggests that suppressor of cytokine signaling 1 (SOCS1) is crucial for the negative regulation of inflammation. We investigated the relationship between smoking, SOCS1, and leukotriene B4 (LTB4) in vitro and in clinical samples of COPD; besides which we detected the impact of LTB4 receptor 1 (BLT1) antagonist on inflammation. METHODS SOCS1 expression in bronchial mucosa was determined by immunohistochemistry and real-time polymerase chain reaction. We also detect SOCS1 and BLT1 expression in alveolar macrophages from bronchoalveolar lavage fluid (BALF) by real time-PCR, in addition to measuring the level of cytokines in BALF using enzyme-linked immunosorbent assay. In vitro, we investigated the expression of SOCS1 in cigarette smoke extract-induced mouse macrophage cell line RAW264.7 by real-time polymerase chain reaction and Western blot, and detected the level of cytokines in the supernatant by enzyme-linked immunosorbent assay. Then, we investigated the effects of BLT1 antagonist U-75302 on SOCS1 expression in these cells. RESULTS We obtained endobronchial biopsies (15 COPD patients and 12 non-COPD control subjects) and BALF (20 COPD patients and 20 non-COPD control subjects), and our results showed that SOCS1 expression significantly decreased in lung tissues from COPD patients. Inflammatory cytokines in BALF were higher in COPD and these inflammatory cytokines negatively correlate with SOCS1 levels. Further, the BLT1 antagonist restored SOCS1 expression and in turn inhibited inflammatory cytokine secretion in vitro. CONCLUSION Long-term cigarette smoke exposure induced SOCS1 degradation and LTB4 accumulation, which was associated with emphysema and inflammation. A BLT1 antagonist might be a potential therapeutic candidate for the treatment of COPD.

Abstract
BACKGROUND AND PURPOSE Vasoactive intestinal peptide is expressed in the respiratory tract and induces its effects via its receptors, VPAC(1) and VPAC(2). RO5024118 is a selective VPAC(2) receptor agonist derived via chemical modification of an earlier VPAC(2) agonist, RO0251553. In the present studies, we characterized the pharmacological activity of RO5024118. EXPERIMENTAL APPROACH Stability of RO5024118 to human neutrophil elastase was assessed. Bronchodilatory activity of RO5024118 was investigated in guinea pig and human isolated airway smooth muscle preparations and in a guinea pig bronchoconstriction model. Pulmonary anti-inflammatory activity of RO5024118 was investigated in a lipopolysaccharide mouse model and in a porcine pancreatic elastase (PPE) rat model. KEY RESULTS RO5024118 demonstrated increased stability to neutrophil elastase compared with RO0251553. In human and guinea pig isolated airway preparations, RO5024118 induced bronchodilatory effects comparable with RO0251553 and the long-acting β-agonist salmeterol and was significantly more potent than native vasoactive intestinal peptide and the short-acting β-agonist salbutamol. In 5-HT-induced bronchoconstriction in guinea pigs, RO5024118 exhibited inhibitory activity with similar efficacy as, and longer duration than, RO0251553. In a lipopolysaccharide-mouse model, RO5024118 inhibited neutrophil and CD8(+) cells and myeloperoxidase levels. In rats, intratracheal instillation of PPE induced airway neutrophilia that was resistant to dexamethasone. Pretreatment with RO5024118 significantly inhibited PPE-induced neutrophil accumulation. CONCLUSIONS AND IMPLICATIONS These results demonstrate that RO5024118 induces dual bronchodilatory and pulmonary anti-inflammatory activity and may be beneficial in treating airway obstructive and inflammatory diseases.

Abstract
BACKGROUND Tobacco smoking irritates and damages the respiratory tract and contributes to a higher risk of developing lung emphysema. At present, smoking cessation is the only effective treatment for reducing the progression of lung emphysema, however, there is hardly anything known about the effects of smoking cessation on cytokine and chemokine levels in the airways. To the best of our knowledge, this is the first reported in vivo study in which cytokine profiles were determined after cessation of cigarette smoke exposure. METHODS The severity of airway remodeling and inflammation was studied by analyzing alveolar enlargement, heart hypertrophy, inflammatory cells in the bronchoalveolar lavage fluid (BALF) and lung tissue and by determining the cytokine and chemokine profiles in the BALF of A/J mice exposed to cigarette smoke for 20 weeks and 8 weeks after smoking cessation. RESULTS The alveolar enlargement and right ventricle heart hypertrophy found in smoke-exposed mice remained unchanged after smoking cessation. Although the neutrophilic inflammation in the BALF of cigarette smoke-exposed animals was reduced after smoking cessation, a sustained inflammation in the lung tissue was observed. The elevated cytokine (IL-1 alpha and TNF-alpha) and chemokine (CCL2 and CCL3) levels in the BALF of smoke-exposed mice returned to basal levels after smoking cessation, while the increased IL-12 levels did not return to its basal level. The cigarette smoke-enhanced VEGF levels did not significantly change after smoking cessation. Moreover, IL-10 levels were reduced in the BALF of smoke-exposed mice and these levels were still significantly decreased after smoking cessation compared to the control animals. CONCLUSION The inflammatory changes in the airways caused by cigarette smoke exposure were only partially reversed after smoking cessation. Although smoking cessation should be the first step in reducing the progression of lung emphysema, additional medication could be provided to tackle the sustained airway inflammation.

Abstract
BACKGROUND Allergic diseases are a significant global health care problem. Current pharmacological approaches address symptoms but do not alter the underlying immune dysregulation. Current allergen-specific immunotherapy has several drawbacks. Therefore, approaches that attenuate allergic responses safely and effectively at the level of upstream causative events are desirable. Oligonuleotide-based therapies [CpG DNA, antisense oligonucleotides, and small interfering RNA (siRNA)] are promising approaches. OBJECTIVE/METHODS We review developments in oligonucleotide-based therapies and the potential of siRNA for treating allergy. RESULTS/CONCLUSIONS Strategies with oligonucleotides basically aim to reduce T helper type 2 (Th2) responses. It is controversial whether the reduction of Th2 responses does, in fact, attenuate allergic diseases. Increased understanding of allergic mechanisms will enhance the efficacy of oligonucleotide-based therapy.

Abstract
RATIONALE Mast cells and neutrophils are key contributors to the pathophysiological inflammatory processes that underpin asthma and chronic obstructive pulmonary disease, partly through the release of noxious serine proteases, including cathepsin G (Cat G) and chymase. From this standpoint, a dual inhibitor of neutrophil Cat G and mast cell chymase could protect against these disease-related inflammatory responses. OBJECTIVES We examined the antiinflammatory pharmacology of RWJ-355871, a dual inhibitor of Cat G and chymase, in animal models of inflammation that evince pathophysiological pathways relevant to asthma and chronic obstructive pulmonary disease to determine the therapeutic potential of this compound. METHODS In an ovalbumin (OVA)-sensitized rat model, RWJ-355871 was administered to block the mast-cell-mediated increase in paw volume caused by OVA injection. In a sheep asthma model, antigen-induced airway responses were assessed with and without aerosol treatment with RWJ-355871. In a murine tobacco-smoke model of airway inflammation, the effect of RWJ-355871 on smoke-induced neutrophilia was determined. MEASUREMENTS AND MAIN RESULTS Intravenous treatment of OVA-sensitized rats with RWJ-355871 provided dose-dependent reduction in the increase in rat paw volume. In allergic sheep, aerosol pretreatment with RWJ-355871 showed dose-dependent inhibition of the antigen-induced early response, late response, and post-antigen-induced airway hyperreponsiveness. In tobacco-smoke-exposed mice, nebulized RWJ-355871 significantly reduced the smoke-induced neutrophilia from the levels observed in untreated mice. CONCLUSIONS The preclinical antiinflammatory effects of RWJ-355871 in these animal models of inflammation indicate that this dual inhibitor may have therapeutic utility for treating airway inflammatory diseases involving mechanisms that depend on Cat G and/or chymase.

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
Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that belong to the nuclear hormone receptor superfamily. PPARgamma regulates several metabolic pathways by binding to sequence-specific PPAR response elements in the promoter region of genes involved in lipid biosynthesis and glucose metabolism. However, more recently PPARgamma, PPARalpha and PPARbeta/delta agonists have been demonstrated to exhibit anti-inflammatory and immunomodulatory properties thus opening up new avenues for research. The actions of PPARgamma and PPARalpha activation are thought to be due to their ability to down regulate pro-inflammatory gene expression and inflammatory cell functions, and as such makes them an attractive target for novel drug intervention. Interestingly, PPARbeta/delta has been shown to be involved in wound healing, angiogenesis, lipid metabolism and thrombosis. In this review we will focus on the data describing the beneficial effects of these ligands in the airway and in the pulmonary vasculature and in vivo in animal models of allergic and occupational asthma, chronic obstructive pulmonary disease and pulmonary fibrosis. A clinical trial is underway to examine the effect of rosiglitazone in asthma patients and the outcome of this trial is awaited with much anticipation. In conclusion, PPARs are novel targets for lung disease and continued work with these ligands may result in a potential new treatment for chronic inflammatory lung diseases.

Abstract
Monocyte chemoattractant protein-1 (MCP-1) is a major chemoattractant for monocytes and memory T cells by means of their binding to its specific cell-surface receptor, CC-chemokine receptor-2 (CCR2). CCR2 belongs to the G-protein-coupled seven-transmembrane receptor superfamily. The evidence in favor of CCR2 and MCP-1 having dominant roles in monocyte chemotaxis and chronic inflammation was provided by CCR2 and MCP-1 knockout mice. It has been recognized that CCR2 antagonists are potential therapeutic agents in preventing, treating, or ameliorating a CCR2-mediated inflammatory syndrome or disease such as psoriasis, uveitis, rheumatoid arthritis, multiple sclerosis, asthma, obesity, and chronic obstructive pulmonary disease. This review summarizes recent developments in small-molecule CCR2 antagonists disclosed by patent applications published between 2005 and 2008 and related publications.

Abstract
Matrix metalloprotease 12 plays a significant role in airway inflammation and remodeling. Increased expression and production of MMP-12 have been found in the lung of human COPD patients. MMP408 (14), a potent and selective MMP-12 inhibitor, was derived from a potent matrix metalloprotease 2 and 13 inhibitor via lead optimization and has good physical properties and bioavailability. The compound blocks rhMMP-12-induced lung inflammation in a mouse model and was advanced for further development for the treatment of COPD.

Abstract
The anti-asthmatic agent andolast is thought to inhibit the release of allergic mediators, but its mechanism of action is not fully understood. We investigated whether the compound inhibits immunoglobulin E (IgE) synthesis and tested the hypothesis that andolast affects immunoglobulin class switching. Interleukin (IL)-4 and the interaction of CD40 expressed on B cells with its ligand on T cells are necessary for IgE synthesis. Thus, peripheral blood mononuclear cells (PBMCs) from 40 asthmatic, 16 non-asthmatic allergic, and 9 normal donors were stimulated with IL-4 and/or anti-CD40 antibody. T cells from 9 additional allergic donors were activated with anti-CD3/CD28 antibodies to express IL-4 mRNA. After incubation in the absence or presence of test compounds, immunoglobulin concentrations were measured by enzyme immunoassay, and mRNA levels were analyzed by RT-PCR. Andolast significantly inhibited IgE synthesis by stimulated PBMCs from both asthma patients and combined allergic/normal donors. In mechanistic studies, andolast was found to act at different cellular levels. Firstly, it reduced by about 45 percent (p<0.05) the levels of IL-4 mRNA in T cells stimulated with anti-CD3/CD28. Secondly, andolast reduced by about 36 percent (p<0.05) the expression of epsilon germline transcripts in PBMCs stimulated with IL-4/anti-CD40. Thirdly, the effect of andolast on immunoglobulin synthesis was selective in that the production of IgG4 antibodies was not significantly inhibited. Our findings, while supporting the evidence that andolast is effective for the treatment of asthma, provide new insights into its mechanism of action.

Abstract
Peroxisome proliferator-activated receptor-alpha (PPARalpha) is implicated in the control of airway inflammation. However, little is known so far about PPARalpha expression and regulation in the lung. Our aim was to assess PPARalpha expression in the lung from normal mice, as well as to investigate its regulation during airway inflammation or in response to anti-inflammatory agents. The PPARalpha activator, fenofibrate, the glucocorticoid, dexamethasone or vehicle was administered to normal mice, to mice exposed to tumor necrosis factor-alpha (TNF-alpha) or lipopolysaccharide (LPS) or to ovalbumin (OVA)-sensitized and challenged animals. PPARalpha expression was assessed by quantifying PPARalpha mRNA levels using real-time quantitative PCR after reverse-transcription of total lung RNA. Airway inflammation was evaluated by determining total and differential cell counts, as well as TNF-alpha production in bronchoalveolar lavage fluids. PPARalpha mRNA was found at significant levels in the lung from normal mice. This expression was increased by 65% (p<0.05) and 55% (p<0.05) in animals treated with fenofibrate and dexamethasone, respectively. In mice exposed to TNF-alpha or LPS, as well as in animals sensitized and challenged with OVA, that exhibited airway inflammation, PPARalpha mRNA was decreased by 60% (p<0.05), 43% (p<0.05) and 50% (p<0.05), respectively. In mice exposed to LPS, down-regulation of PPARalpha was maximal at 4h, whereas TNF-alpha production and cell infiltration peaked at 2 and 24h, respectively. In the lung of mice exposed to LPS or OVA and treated with fenofibrate or dexamethasone, PPARalpha down-regulation was suppressed, while airway inflammation was abolished. Our data showed that PPARalpha is constitutively expressed in mouse lung and down-regulated in response to TNF-alpha or upon acute or allergic airway inflammation. Fenofibrate and dexamethasone upregulated PPARalpha in normal lung and suppressed PPARalpha down-regulation associated with airway inflammation. Taken together, our data show that PPARalpha expression is inversely regulated with lung inflammation.

Abstract
In the present study, we have assessed the effect of the peroxisome proliferator-activated receptor-alpha (PPARalpha) agonist fenofibrate on allergen-induced airway inflammation and immune response. C57BL/6 or PPARalpha knock-out (PPARalpha(-/-)) mice were sensitized with ovalbumin and challenged with ovalbumin alone or with ovalbumin+lipopolysaccharides. Fenofibrate was administered to allergen-exposed animals during challenge only or from the day prior to sensitization to the end of challenge. Inflammation and immune response were assessed by determining cell counts and cytokine levels in bronchoalveolar lavage fluids, expression of the transcription factors Gata-3 and T-bet in lung tissue and ovalbumin-specific IgE and IgG2a in serum. Treatment with fenofibrate (0.15-15 mg/day) during allergen challenge dose-dependently reduced airway inflammatory cell infiltrate induced by ovalbumin in C57BL/6 mice. Reduction reached 74.3% (P<0.001) in animals treated with 15 mg/day of the PPARalpha agonist, whereas this treatment failed to suppress cell infiltrate induced by allergen in PPARalpha(-/-) mice. In addition, when administered from the day prior to sensitization to the end of challenge, fenofibrate (15 mg/day) triggered switching of the immune response to allergen towards a Th1 profile, as evidenced by an increase in IgG2a levels, a reduction in IL(interleukin)-4 and IL-5 together with an increase in interferon-gamma, and a decrease in Gata-3/T-bet expression ratio. Upon challenge with ovalbumin+lipopolysaccharides, sensitized mice developed a severe inflammatory response characterized by infiltration of eosinophils, neutrophils, lymphocytes and macrophages and by increased release of IL-4, IL-5, tumor necrosis factor-alpha, macrophage-inflammatory protein-2 and monocyte chemoattractant protein-1. Administration of fenofibrate during allergen challenge dramatically reduced all responses. In conclusion, our data clearly demonstrate that fenofibrate exhibits an anti-inflammatory activity in allergic asthma, including in severe conditions, and that the PPARalpha agonist is also capable of switching the immune response to allergen towards a Th1 profile when given from the day prior to sensitization.

Abstract
A series of substituted dipiperidine compounds have been synthesized and identified as selective CCR2 antagonists. Combining the most favorable substituents led to the discovery of remarkably potent CCR2 antagonists displaying IC50 values in the nanomolar range. Compound 7a had outstanding selectivity over CCR1, CCR3, CCR4, CCR5, CCR6, CCR7, and CCR8 and showed excellent efficacy in adjuvant-induced arthritis model, collagen-induced arthritis model, and allergic asthma model.

Abstract
1. Our study was aimed at investigating the duration of the bronchodilator action of the antimuscarinc drug glycopyrrolate compared to tiotropium and ipratropium. In the guinea-pig isolated trachea, the time (t1/2) necessary for a contractile response to carbachol (0.3 microM) to return to 50% recovery after washout of the antagonist was studied. The offset of the antagonist effect of glycopyrrolate, tiotropium and ipratropium (10 nM each) was t1/2 = 4.0 +/- 0.5, > 4.5 and 0.5 +/- 0.1 h, respectively. At 4.5 h from the washout of the antagonist, the recovery of the response to carbachol was 50 +/- 8, 10 +/- 4 and 70 +/- 7%, respectively. 2. In the human isolated bronchus, the offset of the bronchodilator effects of glycopyrrolate (3 nM), tiotropium (1 nM) and ipratropium (10 nM) was t1/2 = 3.7 +/- 0.2; > 6 and 3.0 +/- 0.2 h, respectively. At 6.0 h from the washout of the antagonist, the recovery of the response to carbachol (1 microM) was 101 +/- 10, 27 +/- 3 and 110 +/- 10%, respectively. 4. In anaesthetized guinea-pigs, acetylcholine-induced bronchoconstriction was markedly reduced by intratracheal instillation of glycopyrrolate (3 nmol kg(-1); 88.1 +/- 4% inhibition), tiotropium (1.3 nmol kg(-1); 86.2 +/- 5% inhibition) or ipratropium (1.45 nmol kg(-1); 88.1 +/- 10% inhibition). These inhibitory effects assessed 3 or 24 h after antagonist administration were reduced to 69.9 +/- 5 and 29.7 +/- 6%; 28.3 +/- 5 and 14.2 +/- 5% for glycopyrrolate and ipratropium, respectively, whereas they remained stable (83.5 +/- 4; 70.6 +/- 6) for tiotropium. The residual inhibitory effect of glycopyrrolate was also assessed at 16 h from administration, and proved to be as low as that found at 24 h (31.2 +/- 10 vs 29.7 +/- 6%, respectively). 5. In conclusion, glycopyrrolate-induced bronchodilation has a longer duration than that of ipratropium, but less than that of tiotropium. The efficacy of a possible glycopyrrolate-based therapy for asthma or chronic obstructive pulmonary disease given once-a-day is not guaranteed by the present investigation.

Abstract
Advances in genetic engineering and biotechnology, in parallel to increased understanding of disease processes and mechanisms of protective immunity, have facilitated the development of novel rational vaccination concepts for allergy. The spectrum ranges from utilizing recombinant proteins, peptides, new adjuvants, immunomodulatory therapy and DNA vaccines, to use of new application routes for both prophylaxis and treatment of allergic disease. New therapeutic concepts based on patient-tailored immunotherapy using recombinant allergens, anti-IgE and sublingual immunotherapies are slowly moving from the bench to the clinics. The additive value of new treatments above existing therapies must be, however, focused on the improvement of efficacy for long-term cure and increased patient compliance to warrant a broad applicability that has to compete with the symptomatic control of allergic and asthmatic diseases of currently available drugs.
