Abstract
The detailed crosstalk between the neuroendocrine and immune systems in Oreochromis niloticus, an economically important fish, in response to pathogenic infections, remains unclear. This study revealed the head kidney transcriptional profiles of O. niloticus upon infections with Streptococcus agalactiae, a prevalent pathogen known to cause severe meningitis. Twelve cDNA libraries of O. niloticus head kidney, representing four treatment time points (0, 6, 24, and 48 h), were constructed and a total of 2,528 differentially expressed genes were identified based on pairwise comparisons. KEGG pathway analysis revealed a significant enrichment of the 'neuroactive ligand-receptor interaction' pathway (ko04080), with 13 genes exhibiting differential expression during S. agalactiae infection. Among these, six neuroactive receptor genes (lepr, nr3c1, ptger4, thrb, tspo, and β2-ar) were selected, cloned, and characterized. Although these genes are ubiquitously expressed, and in head kidney leukocytes, their expression was mainly observed in T cells, Mo/Mφ, and NCCs, which are characterized by antimicrobial responses. Furthermore, we examined the response patterns of these six neuroactive receptor genes to gram-positive (S. agalactiae) and gram-negative (Aeromonas hydrophila) bacteria in four different tissues. Notably, lepr, ptger4, tspo, and β2-ar were upregulated in all selected tissues in response to S. agalactiae and A. hydrophila infections. However, nr3c1 and thrb were downregulated in response to S. agalactiae infection in the head kidney and spleen, whereas nr3c1 was upregulated, and thrb was unresponsive to A. hydrophila infection. Our findings provide a theoretical foundation for understanding new links between the neuroendocrine and immune systems during bacterial infection in teleost fish.

Long-acting muscarinic antagonist (LAMA) plus long-acting beta-agonist (LABA) versus LABA plus inhaled corticosteroid (ICS) for stable chronic obstructive pulmonary disease. Cochrane Database Syst Rev 2023; 6:CD012066. [PMID: 37276335 PMCID: PMC10241721 DOI: 10.1002/14651858.cd012066.pub3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 06/07/2023]
Abstract
BACKGROUND Long-acting beta-agonists (LABAs), long-acting muscarinic antagonists (LAMAs), and inhaled corticosteroids (ICSs) are inhaled medications used to manage chronic obstructive pulmonary disease (COPD). When two classes of medications are required, a LAMA plus an ICS (LABA+ICS) were previously recommended within a single inhaler as the first-line treatment for managing stable COPD in people in high-risk categories. However, updated international guidance recommends a LAMA plus a LABA (LAMA+LABA). This systematic review is an update of a Cochrane Review first published in 2017. OBJECTIVES To compare the benefits and harms of LAMA+LABA versus LABA+ICS for treatment of people with stable COPD. SEARCH METHODS We performed an electronic search of the Cochrane Airways Group Specialised Register, ClinicalTrials.gov, and the World Health Organization Clinical Trials Search Portal, followed by handsearches. Two review authors screened the selected articles. The most recent search was run on 10 September 2022. SELECTION CRITERIA We included parallel or cross-over randomised controlled trials of at least one month's duration, comparing LAMA+LABA and LABA+ICS for stable COPD. We included studies conducted in an outpatient setting and irrespective of blinding. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and evaluated risk of bias. We resolved any discrepancies through discussion. We analysed dichotomous data as odds ratios (ORs), and continuous data as mean differences (MDs), with 95% confidence intervals (CIs) using Review Manager 5. Primary outcomes were: participants with one or more exacerbations of COPD; serious adverse events; quality of life, as measured by the St. George's Respiratory Questionnaire (SGRQ) total score change from baseline; and trough forced expiratory volume in one second (FEV1). We used the GRADE framework to rate our certainty of the evidence in each meta-analysis as high, moderate, low or very low. MAIN RESULTS: This review updates the first version of the review, published in 2017, and increases the number of included studies from 11 to 19 (22,354 participants). The median number of participants per study was 700. In each study, between 54% and 91% (median 70%) of participants were males. Study participants had an average age of 64 years and percentage predicted FEV1 of 51.5% (medians of study means). Included studies had a generally low risk of selection, performance, detection, attrition, and reporting biases. All but two studies were sponsored by pharmaceutical companies, which had varying levels of involvement in study design, conduct, and data analysis. Primary outcomes The odds of having an exacerbation were similar for LAMA+LABA compared with LABA+ICS (OR 0.91, 95% CI 0.78 to 1.06; I2 = 61%; 13 studies, 20,960 participants; moderate-certainty evidence). The odds of having a serious adverse event were also similar (OR 1.02, 95% CI 0.91 to 1.15; I2 = 20%; 18 studies, 23,183 participants; high-certainty evidence). Participants receiving LAMA+LABA had a similar improvement in quality of life, as measured by the SGRQ, to those receiving LABA+ICS (MD -0.57, 95% CI -1.36 to 0.21; I2 = 78%; 9 studies, 14,437 participants; moderate-certainty evidence) but showed a greater improvement in trough FEV1 (MD 0.07, 95% CI 0.05 to 0.08; I2 = 73%; 12 studies, 14,681 participants; moderate-certainty evidence). Secondary outcomes LAMA+LABA decreased the odds of pneumonia compared with LABA+ICS from 5% to 3% (OR 0.61, 95% CI 0.52 to 0.72; I2 = 0%; 14 studies, 21,829 participants; high-certainty evidence) but increased the odds of all-cause death from 1% to 1.4% (OR 1.35, 95% CI 1.05 to 1.75; I2 = 0%; 15 studies, 21,510 participants; moderate-certainty evidence). The odds of achieving a minimal clinically important difference of four or more points on the SGRQ were similar between LAMA+LABA and LABA+ICS (OR 1.06, 95% CI 0.90 to 1.25; I2 = 77%; 4 studies, 13,614 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS Combination LAMA+LABA therapy probably holds similar benefits to LABA+ICS for exacerbations and quality of life, as measured by the St George's Respiratory Questionnaire, for people with moderate to severe COPD, but offers a larger improvement in FEV1 and a slightly lower risk of pneumonia. There is little to no difference between LAMA+LABA and LAMA+ICS in the odds of having a serious adverse event. Whilst all-cause death may be lower with LABA+ICS, there was a very small number of events in the analysis, translating to a low absolute risk. Findings are based on moderate- to high-certainty evidence from heterogeneous trials with an observation period of less than one year. This review should be updated again in a few years.

Abstract
The ongoing Coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has imposed a huge threat to public health across the world. While vaccinations are essential for reducing virus transmission and attenuating disease severity, the nature of high mutation rate of SARS-CoV-2 renders vaccines less effective, urging quick development of effective therapies for COVID-19 disease. However, developing novel drugs remains extremely challenging due to the lengthy process and high cost. Alternatively, repurposing of existing drugs on the market represents a rapid and safe strategy for combating COVID-19 pandemic. Bronchodilators are first line drugs for inflammatory lung diseases, such as asthma and chronic obstructive pulmonary disease (COPD). Compared to other anti-inflammatory drugs repurposed for COVID-19, bronchodilators are unique in that they have both anti-inflammatory and bronchodilating properties. Whether the dual properties of bronchodilators empower them greater potential to be repurposed for COVID-19 is worth exploring. In fact, clinical and preclinical studies have recently emerged to investigate the benefits of bronchodilators such assalbutamol, formoterol and theophylline in treating COVID-19, and many of them have shown encouraging efficacy on attenuating disease severity of pneumonia and other associated symptoms. To comprehensively understand the latest progress on COVID-19 intervention with bronchodilators, this review will summarize recent findings in this area and highlight the promising clinical benefits and possible adverse effects of bronchodilators as therapeutic options for COVID-19 with a focus on β2 receptor agonists, anticholinergic drugs and theophylline.

Kidney Int 2022; 102:1073-1089. [PMID: 35779607 DOI: 10.1016/j.kint.2022.05.032] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 04/22/2022] [Accepted: 05/20/2022] [Indexed: 12/14/2022]
Abstract
The β2 adrenergic receptor agonist, formoterol, is an inducer of mitochondrial biogenesis and restorer of mitochondrial and kidney function in acute and chronic models of kidney injury. Unfortunately, systemic administration of formoterol has the potential for adverse cardiovascular effects, increased heart rate, and decreased blood pressure. To minimize these effects, we developed biodegradable and biocompatible polymeric nanoparticles containing formoterol that target the kidney, thereby decreasing the effective dose, and lessen cardiovascular effects while restoring kidney function after injury. Male C57Bl/6 mice, treated with these nanoparticles daily, had reduced ischemia-reperfusion-induced serum creatinine and kidney cortex kidney injury molecule-1 levels by 78% and 73% respectively, compared to control mice six days after injury. With nanoparticle therapy, kidney cortical mitochondrial number and proteins reduced by ischemic injury, recovered to levels of sham-operated mice. Tubular necrosis was reduced 69% with nanoparticles treatment. Nanoparticles improved kidney recovery even when the dosing frequency was reduced from daily to two days per week. Finally, compared to treatment with formoterol-free drug alone, these nanoparticles did not increase heart rate nor decrease blood pressure. Thus, targeted kidney delivery of formoterol-containing nanoparticles is an improvement in standard formoterol therapy for ischemia-reperfusion-induced acute kidney injuries by decreasing the dose, dosing frequency, and cardiac side effects.

Tissue Eng Part A 2022; 28:795-806. [PMID: 35620911 PMCID: PMC9634984 DOI: 10.1089/ten.tea.2022.0036] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 04/21/2022] [Indexed: 11/12/2022] Open
Abstract
Volumetric muscle loss (VML) injuries represent a majority of military service member casualties and are common in civilian populations following blunt and/or penetrating traumas. Characterized as a skeletal muscle injury with permanent functional impairments, there is currently no standard for rehabilitation, leading to lifelong disability. Toward developing rehabilitative strategies, previous research demonstrates that the remaining muscle after a VML injury lacks similar levels of plasticity or adaptability as healthy, uninjured skeletal muscle. This may be due, in part, to impaired innervation and vascularization of the remaining muscle, as well as disrupted molecular signaling cascades commonly associated with muscle adaptation. The primary objective of this study was to assess the ability of four pharmacological agents with a strong record of modulating muscle contractile and metabolic function to improve functional deficits in a murine model of VML injury. Male C57BL/6 mice underwent a 15% multimuscle VML injury of the posterior hindlimb and were randomized into drug treatment groups (formoterol [FOR], 5-aminoimidazole-4-carboxamide riboside [AICAR], pioglitazone [PIO], or sildenafil [SIL]) or untreated VML group. At the end of 60 days, the injury model was first validated by comparison to age-matched injury-naive mice. Untreated VML mice had 22% less gastrocnemius muscle mass, 36% less peak-isometric torque, and 27% less maximal mitochondrial oxygen consumption rate compared to uninjured mice (p < 0.01). Experimental drug groups were, then, compared to VML untreated, and there was minimal evidence of efficacy for AICAR, PIO, or SIL in improving contractile and metabolic functional outcomes. However, FOR-treated VML mice had 18% greater peak isometric torque (p < 0.01) and permeabilized muscle fibers had 36% greater State III mitochondrial oxygen consumption rate (p < 0.01) compared to VML untreated mice, suggesting an overall improvement in muscle condition. There was minimal evidence that these benefits came from greater mitochondrial biogenesis and/or mitochondrial complex protein content, but could be due to greater enzyme activity levels for complex I and complex II. These findings suggest that FOR treatment is candidate to pair with a rehabilitative approach to maximize functional improvements in VML-injured muscle. Impact statement Volumetric muscle loss (VML) injuries result in deficiencies in strength and mobility, which have a severe impact on patient quality of life. Despite breakthroughs in tissue engineering, there are currently no treatments available that can restore function to the affected limb. Our data show that treatment of VML injuries with clinically available and FDA-approved formoterol (FOR), a beta-agonist, significantly improves strength and metabolism of VML-injured muscle. FOR is therefore a promising candidate for combined therapeutic approaches (i.e., regenerative rehabilitation) such as pairing FOR with structured rehabilitation or cell-seeded biomaterials as it may provide greater functional improvements than either strategy alone.

Overuse of Short-Acting Beta-2 Agonists (SABAs) in Elite Athletes: Hypotheses to Explain It. Sports (Basel) 2022; 10:sports10030036.

Abstract
The use of short-acting beta-2 agonists (SABAs) is more common in elite athletes than in the general population, especially in endurance sports. The World Anti-Doping Code places some restrictions on prescribing inhaled β2-agonists. These drugs are used in respiratory diseases (such as asthma) that might reduce athletes’ performances. Recently, studies based on the results of the Olympic Games revealed that athletes with confirmed asthma/airway hyperresponsiveness (AHR) or exercise-induced bronchoconstriction (EIB) outperformed their non-asthmatic rivals. This overuse of SABA by high-level athletes, therefore, raises some questions, and many explanatory hypotheses are proposed. Asthma and EIB have a high prevalence in elite athletes, especially within endurance sports. It appears that many years of intensive endurance training can provoke airway injury, EIB, and asthma in athletes without any past history of respiratory diseases. Some sports lead to a higher risk of asthma than others due to the hyperventilation required over long periods of time and/or the high environmental exposure while performing the sport (for example swimming and the associated chlorine exposure). Inhaled corticosteroids (ICS) have a low efficacy in the treatment of asthma and EIB in elite athletes, leading to a much greater use of SABAs. A significant proportion of these high-level athletes suffer from non-allergic asthma, involving the th1-th17 pathway.

Abstract
Heat stress (HS) triggers oxidative stress, systemic inflammation, and disrupts growth efficiency of livestock. β-adrenergic agonists supplemented to ruminant livestock improve growth performance, increase skeletal muscle mass, and decrease carcass fat. The objective of this study was to understand the independent and interacting effects of HS and zilpaterol hydrochloride (ZH) supplementation on the transcriptome of subcutaneous white adipose tissue and the longissimus dorsi muscle in steers. Twenty-four Red Angus-based steers were assigned to thermoneutral (TN; Temperature Humidity Index [THI] = 68) or HS (THI = 73-85) conditions and were not supplemented or supplemented with ZH (8.33 mg/kg/d) for 21 d in a 2 × 2 factorial. Steers in the TN condition were pair-fed to the average daily feed intake of HS steers. RNA was isolated from adipose tissue and skeletal muscle samples collected via biopsy on 3, 10, and 21 d and sequenced using 3' Tag-Seq to an achieved average depth of 3.6 million reads/sample. Transcripts, mapped to ARS-UCD1.2, were quantified. Differential expression (DE) analyses were performed in DESeq2 with a significance threshold for false discovery rate of 0.05. In adipose, 4 loci (MISP3, APOL6, SLC25A4, and S100A12) were DE due to ZH on day 3, and 2 (RRAD, ALB) were DE due to the interaction of HS and ZH on day 10 (Padj < 0.05). In muscle, 40 loci (including TENM4 and OAZ1) were DE due to ZH on day 10, and 6 loci (HIF1A, LOC101903734, PDZD9, HNRNPU, MTUS1, and TMCO6) were DE due to environment on day 21 (Padj < 0.05). To explore biological pathways altered by environment, supplement, and their interaction, loci with DE (Praw < 0.05) were evaluated in Ingenuity Pathway Analysis. In adipose, 509 pathways were predicted to be altered (P < 0.01): 202 due to HS, 126 due to ZH, and 181 due to the interaction; these included inflammatory pathways predicted to be upregulated due to HS but downregulated due to the interaction of HS and ZH. In muscle, 113 pathways were predicted to be altered (P < 0.01): 23 due to HS, 66 due to ZH, and 24 due to the interaction of HS and ZH. Loci and pathway data in muscle suggest HS induced oxidative stress and that the stress response was moderated by ZH. Metabolic pathways were predicted to be altered due to HS, ZH, and their interaction in both tissues. These data provide evidence that HS and ZH interact to alter expression of genes in metabolic and immune function pathways and that ZH moderates some adverse effects of HS.

Abstract
Background Ovarian chronic inflammation has been known to incidence in the laying hen mainly via increasing laying frequency and microbial infection, especially during late stage of production period. This study was aimed to evaluate beta-2 adrenergic agonist (Beta-2 Adrenergic Agonist, BAA) Salmeterol and beta blocker (Beta Blocker, BB) Propranolol on the gene expression of the ovarian pro- and anti-inflammatory mediators, inflammatory responses of immune system, ovarian functions and, hormones in the laying hens on the late stage of production period. Forty-eight White Leghorn hens aged 92 weeks were used for 4 weeks to be supplemented by Salmeterol and Propranolol. Ovulation rate and follicular growth were determined based on laying frequency and ovarian visual evaluation, respectively; the mRNA expressions of follicular beta-2 adrenergic receptor (Beta-2 Adrenergic Receptor, β2ADR), cyclooxygenases (Cyclooxygenases, COX) 1 and 2, and cytokines were measured by real-time PCR. The plasma concentration of ovarian hormones, cellular, and humoral immune responses were measured via ELISA, heterophil to lymphocyte ratio (Heterophil to Lymphocyte ratio, H:L), and sheep red blood cell (Sheep Red Blood Cell, SRBC) test, respectively. Results As compared to control, both of BAA Salmeterol and BB Propranolol resulted in a significant decrease in the mRNA expression of β2ADR, cyclooxygenases, and pro- and anti-inflammatory cytokines (P < 0.01). A significant elevation was observed in the ovulation rate (P < 0.05), plasma estradiol content on both treated groups (P < 0.05), and the content of progesterone and was just significantly (P < 0.05) increased in Salmeterol group. H:L was reduced in BAA group (P < 0.05), and immunoglobulin (Ig) M was elevated in both treated hens, when compared to control. The results indicated that Salmeterol significantly increases body weight (P < 0.05). Conclusion The stimulation and inhibition of beta-2 adrenergic signaling could reduce ovarian inflammatory condition in addition to enhancing laying efficiency in the aged laying hens.

[PMID: 34306265 PMCID: PMC8296082 DOI: 10.1016/j.curtheres.2021.100625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Accepted: 03/03/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND There are differences of opinion about both the most effective combined therapeutic strategy and the clinical benefit of inhaled corticosteroids in nonasthmatic patients with chronic obstructive pulmonary disease. Furthermore, many inflammatory cytokines are reportedly correlated with severity of the disease. OBJECTIVES To compare the effectiveness of long acting β-agonist + long-acting muscarinic antagonist (LABA + LAMA) versus LABA + inhaled corticosteroid and LAMA + inhaled corticosteroid in nonasthmatic patients with moderate-to-severe chronic obstructive pulmonary disease. To assess the changes that occurred in plasma concentrations of tumor necrosis factor α, fibrinogen, and interleukin 6, and correlate these with disease activity. METHODS In this pilot study, 45 nonasthmatic patients with moderate to severe chronic obstructive pulmonary disease were randomized into 3 groups with 15 patients in each group. Group I (LABA + inhaled corticosteroid) received formoterol/budesonide, group II (LAMA + inhaled corticosteroid) received tiotropium/budesonide and group III (LABA + LAMA) received formoterol/tiotropium for 12 weeks. Patients were assessed initially and then at 4 and 12 weeks by measuring the changes that occurred in forced expiratory volume in 1 second as a percent of predicted and in the modified Medical Research Council dyspnea scale. Plasma concentrations of tumor necrosis factor α, fibrinogen, and interleukin 6 were simultaneously measured. RESULTS The 3 study groups were statistically similar with respect to their demographic data and disease characteristics. All therapeutic options produced an improvement in forced expiratory volume in 1 second as a percent of predicted and in the modified Medical Research Council dyspnea scale as well as a reduction in plasma concentrations of the inflammatory markers. The effects produced by the three therapeutic combinations on forced expiratory volume in 1 second as a percent of predicted, plasma tumor necrosis factor α, interleukin 6, and fibrinogen concentrations were statistically similar after 4 and 12 weeks (4 weeks after treatment: P = 0.358, P = 0.284, P = 0.155, and P = 0.155, respectively, and 12 weeks after treatment: P = 0.710, P = 0.773, P = 0.240, and P = 0.076, respectively). CONCLUSIONS In nonasthmatic patients with moderate to severe chronic obstructive pulmonary disease, the 3 therapeutic combinations showed similar effectiveness. The results of this pilot study also suggest that inflammatory markers can be used to track disease activity. Clinicaltrials.gov identifier: NCT04520230. (Curr Ther Res Clin Exp. 2021; 82:XXX-XXX).

Abstract
β2-Adrenoceptor (β2-AR) agonists are widely used as bronchodilators. The emerge of ultralong acting β2-agonists is an important breakthrough in pulmonary medicine. In this review, we will provide mechanistic insights into the application of β2-agonists in asthma, chronic obstructive pulmonary disease (COPD), and heart failure (HF). Recent studies in β-AR signal transduction have revealed opposing functions of the β1-AR and the β2-AR on cardiomyocyte survival. Thus, β2-agonists and β-blockers in combination may represent a novel strategy for HF management. Allosteric modulation and biased agonism at the β2-AR also provide a theoretical basis for developing drugs with novel mechanisms of action and pharmacological profiles. Overlap of COPD and HF presents a substantial clinical challenge but also a unique opportunity for evaluation of the cardiovascular safety of β2-agonists. Further basic and clinical research along these lines can help us develop better drugs and innovative strategies for the management of these difficult-to-treat diseases.

Activation of β 2 adrenergic receptor signaling modulates inflammation: a target limiting the progression of kidney diseases. Arch Pharm Res 2020; 44:49-62.

Abstract
Beta 2 adrenergic receptor (β2-AR)-agonists, widely used as bronchodilators, have demonstrated wide-spectrum anti-inflammatory properties in both immune and non-immune cells in various tissues. Their anti-inflammatory properties are mediated primarily, but not exclusively, via activation of the canonical β2-AR signaling pathway (β2-AR/cAMP/PKA). As non-canonical β2-AR signaling also occurs, several inconsistent findings on the anti-inflammatory effect of β2-agonists are notably present. Increasing amounts of evidence have unveiled the alternative mechanisms of the β2-AR agonists in protecting the tissues against injuries, i.e., by augmenting mitochondria biogenesis and SIRT1 activity, and by attenuating fibrotic signaling. This review mainly covers the basic mechanisms of the anti-inflammatory effects of β2-AR activation along with its limitations. Specifically, we summarized the role of β2-AR signaling in regulating kidney function and in mediating the progression of acute and chronic kidney diseases. Given their versatile protective effects, β2-agonists can be a promising avenue in the treatment of kidney diseases.

Abstract
Background Even in subjects who are not sensitized to house dust mite (HDM), allergic symptoms can be clinically aggravated by exposure to dust. We previously reported that Dermatophagoides farinae (Df), an important HDM, or Der f 1, a major allergen of Df, induced the effector functions of eosinophils, which may be an important mechanism for HDM-induced symptoms in nonsensitized patients. In a clinical setting, β2-adrenergic agonists, such as salbutamol and formoterol, are used for the treatment of asthma attacks or exacerbation to release the airway obstruction. Several reports have suggested that some β2-adrenergic agonists have an anti-inflammatory capacity. Objective In this study, we investigated whether β2-adrenergic agonist could modify the Df- or Der f 1-induced activation of eosinophils. Methods Blood eosinophils obtained from healthy donors were preincubated with either formoterol (1 μM), salbutamol (1 μM), or buffer control and then stimulated with Df extract (1 μg/mL) or Der f 1 (100 pg/mL). Eosinophil adhesion to intercellular adhesion molecule (ICAM)-1 was measured using eosinophil peroxidase assays. Generation of superoxide anion (O2 -) was examined based on the superoxide dismutase-inhibitable reduction of cytochrome C. Eosinophil-derived neurotoxin (EDN) concentrations in cell media were measured by enzyme-linked immunosorbent assay. Results Formoterol, but not salbutamol, suppressed the Df- or Der f 1-induced eosinophil adhesion to ICAM-1. Furthermore, formoterol, but not salbutamol, suppressed Df-induced O2 - generation or EDN release. Neither formoterol nor salbutamol suppressed spontaneous eosinophil adhesion, O2 - generation, or EDN release. Conclusion These findings suggested that formoterol, but not salbutamol, suppressed Df- or Der f 1-induced eosinophil activation when used at the same concentration. Therefore, formoterol could potentially be used for the treatment of bronchial asthma via both bronchodilation and anti-inflammatory effect.

Abstract
Chronic obstructive pulmonary disease (COPD) is associated with abnormal inflammatory response and airflow limitation. Acute exacerbation involves increased inflammatory burden leading to worsening respiratory symptoms, including dyspnea and sputum production. Some COPD patients have frequent exacerbations (two or more exacerbations per year). A substantial proportion of COPD patients may remain stable without exacerbation. Bacterial and viral infections are the most common causative factors that breach airway stability and lead to exacerbation. The increasing prevalence of exacerbation is associated with deteriorating lung function, hospitalization, and risk of death. In this review, we summarize the mechanisms of airway inflammation in COPD and discuss how bacterial or viral infection, temperature, air pollution, eosinophilic inflammation, and concomitant chronic diseases increase airway inflammation and the risk of exacerbation.

Abstract
Background The systemic inflammation is associated with clinical outcome and mortality in chronic obstructive pulmonary disease (COPD) patients. To investigate the effects of tiotropium (Tio) and/or budesonide/formoterol (Bud/Form) on systemic inflammation biomarkers in stable COPD patients of group D, a randomized, open-label clinical trial was conducted. Methods Eligible participants (n = 324) were randomized and received either Tio 18ug once daily (group I), Bud/Form 160/4.5ug twice daily (group II), Bud/Form 320/9ug twice daily (group III), or Tio 18ug once daily with Bud/Form 160/4.5ug twice daily (group IV) for 6 months. Systemic inflammation biomarkers were measured before randomization and during the treatment, including C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-8 (IL-8), serum amyloid A (SAA), tumor necrosis factor-α (TNF-α), fibrinogen (Fib), and white blood cell (WBC). Results After 6-month treatment, CRP levels in group II, group III and group IV changed by a median (interquartile range) of -1.25 (-3.29, 1.18) mg/L, -1.13 (-2.55, 0.77) mg/L, and -1.56 (-4.64, 0.22) mg/L respectively, all of which with statistical differences compared with group I. In addition, there were no treatment differences in terms of IL-8, SAA, TNF-α, Fib and WBC levels. Conclusions A long-term treatment with Bud/Form alone or together with Tio can attenuate circulating CRP levels in COPD patients of group D, compared with Tio alone.

Abstract
Background β2-adrenoceptor agonists have been shown to reduce the lipopolysaccharide (LPS)-induced cytokine release by human monocyte-derived macrophages (MDMs). We compare the expression of β2-adrenoceptors and the inhibitory effect of formoterol and salmeterol on the LPS-induced release of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6 and a range of chemokines (CCL2, 3, 4, and IL-8) by human lung macrophages (LMs) and MDMs. Methods LMs were isolated from patients undergoing resection and MDMs were obtained from blood monocytes in the presence of GM-CSF. LMs and MDMs were incubated in the absence or presence of formoterol or salmeterol prior to stimulation with LPS. The effects of formoterol were also assessed in the presence of the phosphodiesterase inhibitor roflumilast. Results LPS-induced cytokine production was higher in LMs than in MDMs. Salmeterol and formoterol exerted an inhibitory effect on the LPS-induced production of TNF-α, IL-6, CCL2, CCL3, and CCL4 in MDMs. In contrast, the β2-adrenoceptor agonists were devoid of any effect on LMs - even in the presence of roflumilast. The expression of β2-adrenergic receptors was detected on Western blots in MDMs but not in LMs. Conclusions Concentrations of β2-adrenoceptor agonists that cause relaxation of the human bronchus can inhibit cytokine production by LPS-stimulated MDMs but not by LMs. Electronic supplementary material The online version of this article (doi:10.1186/s12931-017-0613-y) contains supplementary material, which is available to authorized users.

Abstract
Respiratory diseases, always being a threat towards the health of people all over the world, are most tightly associated with immune system. Neutrophils serve as an important component of immune defense barrier linking innate and adaptive immunity. They participate in the clearance of exogenous pathogens and endogenous cell debris and play an essential role in the pathogenesis of many respiratory diseases. However, the pathological mechanism of neutrophils remains complex and obscure. The traditional roles of neutrophils in severe asthma, chronic obstructive pulmonary diseases (COPD), pneumonia, lung cancer, pulmonary fibrosis, bronchitis, and bronchiolitis had already been reviewed. With the development of scientific research, the involvement of neutrophils in respiratory diseases is being brought to light with emerging data on neutrophil subsets, trafficking, and cell death mechanism (e.g., NETosis, apoptosis) in diseases. We reviewed all these recent studies here to provide you with the latest advances about the role of neutrophils in respiratory diseases.

Abstract
BACKGROUND Three classes of inhaler medications are used to manage chronic obstructive pulmonary disease (COPD): long-acting beta-agonists (LABA), long-acting muscarinic antagonists (LAMA), and inhaled corticosteroids (ICS). When two classes of medications are required, LAMA plus LABA (LAMA+LABA) and LABA plus ICS (LABA+ICS) are often selected because these combinations can be administered via a single medication device. The previous Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidance recommended LABA+ICS as the first-line treatment for managing stable COPD in high-risk people of categories C and D. However, the updated GOLD 2017 guidance recommends LAMA+LABA over LABA+ICS. OBJECTIVES To compare the benefits and harms of LAMA+LABA versus LABA+ICS for treatment of people with stable COPD. SEARCH METHODS We performed an electronic search of the Cochrane Airways Group Specialised Register (2 February 2016), ClinicalTrials.gov (4 June 2016), and the World Health Organization Clinical Trials Search Portal (4 June 2016), followed by a handsearch (5 June 2016). Two review authors screened and scrutinised the selected articles. SELECTION CRITERIA We included individual randomised controlled trials, parallel-group trials, and cross-over trials comparing LAMA+LABA and LABA+ICS for stable COPD. The minimum accepted trial duration was one month and trials should have been conducted in an outpatient setting. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and evaluated risk of bias. We resolved any discrepancies through discussion. We analysed dichotomous data as odds ratios (OR), and continuous data as mean differences (MD), with 95% confidence interval (CI) using Review Manager 5. Exacerbations were measured by counting the number of people experiencing one or more exacerbation. MAIN RESULTS We included 11 studies comprising 9839 participants in our quantitative analysis. Most studies included people with moderate to severe COPD, without recent exacerbations. One pharmaceutical sponsored trial that included only people with recent exacerbations was the largest study and accounted for 37% of participants. All but one study were sponsored by pharmaceutical companies, thus we rated them as having a high risk of 'other bias'. The unsponsored study was at high risk of performance and detection bias, and possible selective reporting.Five studies recruited GOLD Category B participants, one study recruited Category D participants, two studies recruited Category A/B participants, and three studies recruited participants regardless of category. Follow-up ranged from 6 to 52 weeks.Compared to the LABA+ICS arm, the results for the pooled primary outcomes for the LAMA+LABA arm were as follows: exacerbations, OR 0.82 (95% CI 0.70 to 0.96, P = 0.01, I2 = 17%, low quality evidence); serious adverse events (SAE), OR 0.91 (95% CI 0.79 to 1.05, P = 0.18, I2 = 0, moderate quality evidence); St. George's Respiratory Questionnaire (SGRQ) total score change from the baseline, MD -1.22 (95% CI -2.52 to 0.07, P = 0.06, I2 = 71%, low quality evidence); and trough forced expiratory volume in one second (FEV1) change from the baseline, MD 0.08 L (95% CI 0.06 to 0.09, P < 0.0001, I2 = 50%, moderate quality evidence). Compared to the LABA+ICS arm, the results for the pooled secondary outcomes for the LAMA+LABA arm were as follows: pneumonia, OR 0.57 (95% CI 0.42 to 0.79, P = 0.0006, I2 = 0%, low quality evidence); all-cause death, OR 1.01 (95% CI 0.61 to 1.67, P = 0.88, I2 = 0%, low quality evidence); and SGRQ total score change from the baseline of 4 points or greater (the minimal clinically important difference for the SGRQ is 4 points), OR 1.25 (95% CI 1.09 to 1.44, P = 0.002, I2 = 0%, moderate quality evidence). AUTHORS' CONCLUSIONS For the treatment of COPD, LAMA+LABA has fewer exacerbations, a larger improvement of FEV1, a lower risk of pneumonia, and more frequent improvement in quality of life as measured by an increase over 4 units or more of the SGRQ. These data were supported by low or moderate quality evidence generated from mainly participants with moderate to severe COPD in heterogeneous trials with an observation period of less than one year. Our findings support the recently updated GOLD guidance.

Abstract
Asthma can be controlled well in most patients by inhaled β-adrenoreceptor (β2 AR) agonists and steroids. Poor response to β2 AR agonists is difficult to predict, especially in young children and by lung function testing, which may be affected by multiple influences. As an alternative approach, we analyzed ex vivo neutrophilic superoxide inhibition in response to β2 AR stimulation. In 60 healthy volunteers, this assay was unaffected by sex, age, smoking, atopy or asthma status. Furthermore, we assessed effects of genetic variants in β2 AR by sequencing the ADRB2 gene in our cohort and relating genotypes to β2 AR-mediated neutrophilic superoxide inhibition. Gly16Arg genotypes correlated with minor decrease in overall adrenoresponse in this small study population. Taken together, ex vivo testing of the β2 AR response in human neutrophils represents a robust tool with good signal-to-noise ratio at physiological β2 AR agonist concentrations, and this assay may be useful to complement future pharmacogenetic studies in asthma.

Allergol Int 2015; 64 Suppl:S46-53. [PMID: 26344080 DOI: 10.1016/j.alit.2015.05.009] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2015] [Revised: 05/17/2015] [Accepted: 05/20/2015] [Indexed: 10/23/2022] Open
Abstract
BACKGROUND Eosinophils play important roles in the development of asthma exacerbation. Viral infection is a major cause of asthma exacerbation, and the expression of IFN-γ-inducible protein of 10 kDa (IP-10) and cysteinyl leukotrienes (cysLTs) is up-regulated in virus-induced asthma. As β2-adrenergic agonists, such as formoterol or salbutamol, are used to treat asthma exacerbation, we examined whether formoterol or salbutamol could modify eosinophil functions such as adhesiveness, particularly those activated by cysLTs or IP-10. METHODS Eosinophils were isolated from the blood of healthy subjects and were pre-incubated with either formoterol or salbutamol, and subsequently stimulated with IL-5, LTD4, or IP-10. Adhesion of eosinophils to intercellular cell adhesion molecule (ICAM)-1 was measured using eosinophil peroxidase assays. The generation of eosinophil superoxide anion (O2(-)) was examined based on the superoxide dismutase-inhibitable reduction of cytochrome C. Eosinophil-derived neurotoxin (EDN) release was evaluated by ELISA as a marker of degranulation. RESULTS Neither formoterol nor salbutamol suppressed the spontaneous adhesion of eosinophils to ICAM-1. However, when eosinophils were activated by IL-5, LTD4, or IP-10, formoterol, but not salbutamol, suppressed the adhesion to ICAM-1. Formoterol also suppressed IL-5, LTD4, or IP-10 induced eosinophil O2(-) generation or EDN release. CONCLUSIONS These findings suggest that formoterol, but not salbutamol, suppresses eosinophil functions enhanced by IL-5, LTD4, or IP-10. As these factors are involved in the development of asthma exacerbation, our results strongly support the hypothesis that administration of formoterol is a novel strategy for treating asthma exacerbation.

Abstract
Enhanced activity of neutrophil elastase leads to a protease–antiprotease imbalance, and plays an essential pathogenic role in acute lung injury (ALI) and acute respiratory distress syndrome. We assayed the pharmacological effects and mechanisms of the action of sirtinol in human neutrophils, and in neutrophil elastase (HNE)-induced paw edema and lipopolysaccharide (LPS)-mediated ALI in mice. Sirtinol significantly inhibited the activity of HNE from human neutrophils in response to various stimulators. The inhibitory effects on HNE activity were not mediated through protein kinase A, calcium, extracellular-regulated kinase, c-Jun N-terminal kinase, p38 mitogen-activated protein kinase, Akt, or Src family kinases. Analysis of enzymatic activities showed that sirtinol inhibited HNE activity in a concentration-dependent manner. These results demonstrate that sirtinol does not affect neutrophil function and is an HNE inhibitor. In addition, administration of sirtinol significantly inhibited HNE-induced paw edema, and attenuated the myeloperoxidase activity and reduced pulmonary wet/dry weight ratio in the LPS-induced ALI mouse model. Our study indicates that sirtinol has anti-inflammatory effects through direct inhibition of HNE activity and attenuates HNE-induced and LPS-mediated tissue or organ injury in vivo. Sirtinol is a novel HNE inhibitor and may have the potential for clinical application in the treatment of inflammatory lung diseases.
