Abstract
Chronic obstructive pulmonary disease (COPD) is one of the most common inflammatory diseases resulting from habitual smoking. Impaired clearance of apoptotic cell by airway macrophages contributes to lung inflammation. Milk fat globule-EGF factor 8 (MFG-E8), as a link between apoptotic cells and phagocytes, facilitates clearance of apoptotic cells and attenuates inflammation. We sought to investigate altered expression and potential role of MFG-E8 in COPD. In this study, apoptosis was increased and the level of MFG-E8 was decreased while HMGB1 expression was increased in lung tissues of CS-exposed mice. Compared with CS-exposed WT mice, more apoptotic cells were accumulated in lung tissues of CS-exposed MFG-E8 deficiency mice. Exposure of a range of macrophages to cigarette smoke extract (CSE) resulted in decreased MFG-E8 expression. Administration of rmMFG-E8 ameliorated phagocytic ability of RAW264.7 cells and suppressed inflammatory response induced by CS-exposure. 10% CSE stimulation suppressed Rac1 membrane localization in RAW264.7 cells which was restored by administration of rmMFG-E8. MFG-E8 deficiency diminished uptake of apoptotic thymocytes by peritoneal macrophages upon CSE exposure. Overall, the findings in current work provide a novel target for diagnosing and treating COPD.

Abstract
RATIONALE Chronic obstructive pulmonary disease (COPD) susceptibility is in part related to genetic variants. Most genetic studies have been focused on genome-wide common variants without a specific focus on coding variants, but common and rare coding variants may also affect COPD susceptibility. OBJECTIVES To identify coding variants associated with COPD. METHODS We tested nonsynonymous, splice, and stop variants derived from the Illumina HumanExome array for association with COPD in five study populations enriched for COPD. We evaluated single variants with a minor allele frequency greater than 0.5% using logistic regression. Results were combined using a fixed effects meta-analysis. We replicated novel single-variant associations in three additional COPD cohorts. MEASUREMENTS AND MAIN RESULTS We included 6,004 control subjects and 6,161 COPD cases across five cohorts for analysis. Our top result was rs16969968 (P = 1.7 × 10(-14)) in CHRNA5, a locus previously associated with COPD susceptibility and nicotine dependence. Additional top results were found in AGER, MMP3, and SERPINA1. A nonsynonymous variant, rs181206, in IL27 (P = 4.7 × 10(-6)) was just below the level of exome-wide significance but attained exome-wide significance (P = 5.7 × 10(-8)) when combined with results from other cohorts. Gene expression datasets revealed an association of rs181206 and the surrounding locus with expression of multiple genes; several were differentially expressed in COPD lung tissue, including TUFM. CONCLUSIONS In an exome array analysis of COPD, we identified nonsynonymous variants at previously described loci and a novel exome-wide significant variant in IL27. This variant is at a locus previously described in genome-wide associations with diabetes, inflammatory bowel disease, and obesity and appears to affect genes potentially related to COPD pathogenesis.

Cigarette smoking following lung transplantation: effects on allograft function and recipient functional performance. J Cardiopulm Rehabil Prev 2015; 35:147-53.

Abstract
PURPOSE Despite mandatory tobacco abstinence following lung transplantation (LTX), some recipients resume smoking cigarettes. The effect of smoking on allograft function, exercise performance, and symptomatology is unknown. METHODS A retrospective review was conducted of LTX recipients who received allografts over an 8-year interval and who were subjected to sequential posttransplant pulmonary function testing (PFT), 6-minute walk (6MW) testing, and assessments of exertional dyspnea (Borg score). Using post-LTX PFT results, recipients were determined to have either bronchiolitis obliterans syndrome (BOS), a manifestation of chronic allograft rejection, or normal pulmonary function (non-BOS). With respect to post-LTX pulmonary function, 6MW distances, and Borg scores, comparisons were made between these recipient groups and those who resumed smoking. RESULTS Of 34 LTX recipients identified, 13 maintained normal lung function (non-BOS), while 16 demonstrated a decline in their PFT values consistent with BOS. Five recipients began smoking at median postoperative day 365 and smoked 1 pack per day for a mean of 485.6 days. Smokers developed a deterioration of their PFT values that was similar to those with BOS (P = .47) and tended to be worse than those in the non-BOS group (P = .09). All smokers experienced a decline in 6MW distances similar to those with BOS and non-BOS but reported less exertional dyspnea (lower Borg scores) than those with BOS. CONCLUSION Recipients of LTX who resume cigarette smoking demonstrate a decline in pulmonary function similar to those afflicted with chronic allograft rejection but do not experience a decrement in their functional performance or increased dyspnea.

Abstract
Pulmonary inflammation and tissue remodelling are common elements of chronic respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), and pulmonary hypertension (PH). In disease, pulmonary mesenchymal cells not only contribute to tissue remodelling, but also have an important role in pulmonary inflammation. This review will describe the immunomodulatory functions of pulmonary mesenchymal cells, such as airway smooth muscle (ASM) cells and lung fibroblasts, in chronic respiratory disease. An important theme of the review is that pulmonary mesenchymal cells not only respond to inflammatory mediators, but also produce their own mediators, whether pro-inflammatory or pro-resolving, which influence the quantity and quality of the lung immune response. The notion that defective pro-inflammatory or pro-resolving signalling in these cells potentially contributes to disease progression is also discussed. Finally, the concept of specifically targeting pulmonary mesenchymal cell immunomodulatory function to improve therapeutic control of chronic respiratory disease is considered.
