The level of IL33 was significantly higher in asthma and MS patients compared to the control group (P< 0.001- P<0.001).The frequency distribution of the genotype in rs1342326 variant of IL-33 gene in patients with asthma, MS and healthy subjects was not significantly different (P>0.05).
<b>Objective:</b> To develop a detection method for single nucleotide polymorphisms (SNPs) of bronchial asthma (BA) susceptibility genes (<i>IL-13</i>, <i>IL-33,</i> and <i>GSDMA</i>) based on fluorescence PCR melting curves.
Together these data demonstrate that rs146597587-C is a loss of function mutation and support the hypothesis that IL-33 haploinsufficiency protects against asthma.
The level of IL-33 was significantly higher in patients with asthma when compared to healthy subjects (672.73 ± 104.47 pg/mL vs 268.52 ± 27.56 pg/mL, P < 0.05).
We demonstrated that low PEF variability over 1 week, high serum IL-10 level, and low serum IL-33 concentration were useful factors for predicting that an adult's asthma will remain in control for months to years after a 50% reduction in the daily ICS dose.
IL-33 EBC levels were significantly increased in IPF (3.41 ± 0.55 pg/ml) compared to healthy controls (1.20 ± 0.60 pg/ml; P < .01) but did not differ from asthma (3.68 pg/ml) and COPD levels (2.47 ± 0.34 pg/ml).
Four were at previously reported loci on 17q21, near IL1RL1, TSLP and IL33, but we report for the first time, to our knowledge, that these loci are associated with asthma risk in three ethnic groups.
Recent findings from biological and genetic studies on eosinophils and basophils highlight the role of epithelial cell-derived cytokines such as TSLP and IL-33 in asthma and allergic diseases.
The aim of the current study was to evaluate the effects of acupuncture on inflammation and regulation of the IL-33/ST2 pathway in a mouse model of asthma.
IL-33 is likely to play a critical role in asthma because the IL33 and ST2/IL1RL1 genes have been reproducibly identified as major susceptibility loci in large-scale genome-wide association studies.
In this study we demonstrate that both ICs and HDM induce expression of IL-33, a critical mediator in asthma pathogenesis and the differentiation of TH2 cells, in DCs.
To determine if airway IL-33 is associated with type-2 inflammation measured by type-2 cytokines, FeNO and sputum eosinophils in patients presenting to the Emergency Department with an asthma exacerbations.
Finally, we showed that IL-33 was more abundantly expressed in the lung epithelial cells of asthma patients than those from healthy controls, suggesting that IL-33 may be involved in lung macrophage activation in clinical asthma.
