Innate immunity but not NLRP3 inflammasome activation correlates with severity of stable COPD.
2014
Background In models of COPD, environmental stressors induce innate immune responses, inflammasome activation and inflammation. However, the interaction between these responses and their role in driving pulmonary inflammation in stable COPD is unknown. Objectives To investigate the activation of innate immunity and inflammasome pathways in the bronchial mucosa and bronchoalveolar lavage (BAL) of patients with stable COPD of different severity and control healthy smokers and non-smokers. Methods Innate immune mediators (interleukin (IL)-6, IL-7, IL-10, IL-27, IL-37, thymic stromal lymphopoietin (TSLP), interferon γ and their receptors, STAT1 and pSTAT1) and inflammasome components (NLRP3, NA…
Authors' response to: epithelial mesenchymal transition (EMT) in small airways of COPD patient.
2013
We understand the reservations highlighted by Sohal and Walters in their letter in response to our recent work published.1 In their letter, Sohal and Walters argue that E-cadherin and ZO-1 are absent in our immunohistochemistry analysis of small bronchi of smokers and COPD patients, and that if disappeared completely epithelium would fall apart.1 In our study, we detected downregulation of E-cadherin and ZO-1 as well as a change of intercellular and apical distribution to diffuse cytoplasmic redistribution (figure 3B; in our work published in Thorax on 7 January 2013),2 but not …
