Cryptotanshinone Attenuates Airway Remodeling by Inhibiting Crosstalk Between Tumor Necrosis Factor-Like Weak Inducer of Apoptosis and Transforming Growth Factor Beta 1 Signaling Pathways in Asthma.
The pooled <i>p</i>-value, odds ratio (OR), and 95% confidence interval (95% CI) were used to investigate the strength of the association of this polymorphism of the <i>TNF-α</i> gene with the risk of asthma.
Higher relative abundance of these bacteria is furthermore associated with an airway immune profile dominated by reduced TNF-α and IL-1β and increased CCL2 and CCL17, which itself is an independent predictor for asthma.
Thus, the very same macrophage-derived mediators, released in controlled amounts to destroy injurious materials and pathogens (eg, reactive oxygen species, reactive nitrogen species, proteases, tumor necrosis factor α) and initiate wound repair (eg, transforming growth factor β, connective tissue growth factor, vascular endothelial growth factor), can exacerbate acute lung injury and/or induce chronic disease such as fibrosis, chronic obstructive pulmonary disease, and asthma, when released in excess.
Androgens, via AR, blunted TNFα or IL-13-induced enhancement of ASM [Ca<sup>2+</sup>]<sub>i</sub> in both males and females, with retained efficacy in asthmatics.
Impaired GRα nuclear translocation and inhibited p-p65 expression might contribute to glucocorticoid resistance caused by MUC1 deficiency in TNF-α-induced necroptosis in 16HBE cells, and should be considered as a potential target for the development of novel therapeutics for asthma.
Using U.S. Medicare and Truven MarketScan databases, we identified three cohorts of RA patients with interstitial lung disease (ILD), chronic obstructive pulmonary disease (COPD), or asthma who initiated abatacept or a TNF inhibitor (TNFi).
RESULTS The levels of serum IgE and IgG in BLA- or Dex- treated mice were significantly reduced compared to those in the asthma (AS) group (P<0.01), whereas the levels of cytokines IL-4, TNF-α, and MCP-1 were significantly decreased (P<0.01).
Airway hyperreactivity (AHR) to inhaled methacholine, levels of IL-6, TNF-α, and differential white blood cells in bronchoalveolar lavage fluid (BALF), and lung histopathology were evaluated.
In this study, we used an allergen-induced asthma model to show that TNF-TNFR2 signaling alleviated allergic airway inflammation by reducing the airway infiltration of eosinophils and neutrophils.
IL-17A synergises with tumour necrosis factor (TNF)-α in the production of the neutrophil chemokine CXCL-8 by primary bronchial epithelial cells (PBECs).We hypothesised that local neutrophilic inflammation in asthma correlates with IL-17A and TNF-α-induced CXCL-8 production by PBECs from asthma patients.PBECs from most asthma patients displayed an exaggerated CXCL-8 production in response to TNF-α and IL-17A, but not to TNF-α alone, and which was also insensitive to corticosteroids.
IL-1β and TNF-α, which are two key pro-inflammatory cytokines that mediate the correlation of depressive symptoms with impaired BDR and neutrophilic airway inflammation, may serve as targeted biomarkers in the neuropsychological phenotype of asthma; however, this result needs to be further validated.
ELISA results illustrated that interleukin (IL)-1, IL-10 and tumor necrosis factor-α (TNF-α) levels were elevated, whereas IL-12 level was reduced in lung tissues of the asthma and 10 µmol/l RES groups whilst the 50 µmol/l RES group demonstrated the opposite trend.
Based on LPS induced sepsis model for the measurement of TNF-α inhibition in Swiss Albino mice and neutrophilia inhibition for asthma and COPD in Sprague Dawley rats with the potential molecules, compound 4 m would be great promise as a hit inhibitor in the future study.
In CD4+ T cells treated with PMA+MLIF, the expression levels of IFN-γ, TNF-α and IL-4 were strongly inhibited (p<0.001, p<0.001 and p<0.0094), compared to PMA treatment alone, for both, rhinitis and asthma.
Their Global Initiative for Asthma⁻based asthma severity, Childhood Asthma Control Test (C-ACT) scores, Pediatric Asthma Severity Scores, Pediatric Asthma Quality of Life Questionnaire scores, peak expiratory flow rates (PEFRs), medication use, the levels of immune biomarkers (immunoglobulin E (IgE), interferon γ, interleukin 4, and tumor necrosis factor α) at different visits, and the associated changes were evaluated.
This study aimed to explore the value of elevated serum levels of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), and eosinophil cationic protein (ECP) in the diagnosis of bronchial asthma (BA).
Significant positive correlations were seen between baseline concentrations of TNF-α in EBC and fall in FEV1 following exercise challenge in athletes during training period (R=0.74, p<0.01) and in asthmatics (R=0.64, p<0.05).
In comparison with that in the healthy control (HC), significantly lower abundance of Bifidobacterium and lower levels of Th1 cytokines (IFN-γ and TNF-α), but higher levels of Th2-type cytokines (IL-4, IL-5) and Th17-type (IL-17A) cytokine were detected in children with bronchiolitis and asthma.
Our findings indicated that TNF-α - 238 G/A, -308 G/A, -857C/T, -863C/A and - 1031 T/C polymorphisms may serve as potential biological markers for asthma in certain ethnicities.
The overexpression of Tumor Necrosis Factor (TNF) is directly related to the development of several autoimmune diseases, such as rheumatoid and psoriatic arthritis, inflammatory bowel disease, Crohn's disease, refractory asthma, and multiple sclerosis.
