Special Issue Information

Dear Colleagues,

This Special Issue is supervised by Dr. Ramcés Falfán-Valencia and assisted by our Topical Advisory Panel members, Dr. Gloria Pérez-Rubio and Dr. Ingrid Fricke-Galindo.

We are pleased to invite you to contribute to our Special Issue of the International Journal of Molecular Sciences (IJMS), titled “Chronic Obstructive Pulmonary Disease (COPD): Molecular Mechanisms and Treatment”. This issue will cover a selection of recent research topics and current review articles, reporting the latest updates on COPD with a particular emphasis on physiopathological mechanisms and novel therapy approaches.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. COPD is a heterogeneous condition; the onset and trajectory are influenced by tobacco smoking, individual genetics, and the environmental exposures individuals accumulate over their life course. There is an urgent need to identify COPD patients at high risk for poor outcomes and understand mechanistically why some individuals are at high risk.

This issue can be addressed by precision medicine approaches, which focus on understanding an individual’s disease risk and tailoring management based on pathobiology, environmental exposures, and biomarkers. Genetics, omics, and network analytic techniques have started to dissect COPD heterogeneity and identify patients with specific pathobiology. Phenotyping individuals based on similar clinical or molecular characteristics can guide appropriate therapeutic management. Treatable traits, characteristics for which evidence supports a treatment response, are being increasingly incorporated into COPD clinical guidelines. However, the COPD phenotyping literature is changing. Innovations in lung imaging, physiologic metrics, omics, and biomarker technologies contribute to a better understanding of COPD heterogeneity.

Inflammation and mucus production are prevalent characteristics of chronic respiratory conditions, such as asthma and chronic chronic obstructive pulmonary disease (COPD). Biological co-factors, including bacteria, viruses, and fungi, may exacerbate these diseases by activating various pathways associated with airway diseases. An example is the fungus Pneumocystis, which is linked to severe COPD in human patients. Recent evidence has demonstrated that Pneumocystis significantly enhanced inflammation and mucus hypersecretion in a rat model of elastase-induced COPD. The present study specifically aims to investigate two additional aspects associated with the pathology induced by Pneumocystis infection: inflammation and collagen deposition around airways. To this end, the focus was to investigate the role of the IL-1β pro-inflammatory pathway during Pneumocystis infection in COPD rats. Several airway pathology-related features, such as inflammation, mucus hypersecretion, and fibrosis, were evaluated using histological and molecular techniques. COPD animals infected with Pneumocystis exhibited elevated inflammation levels, including a synergistic increase in IL-1β and Cox-2. Furthermore, protein levels of the IL-1β-dependent transcription factor cAMP response element-binding (CREB) showed a synergistic elevation of their phosphorylated version in the lungs of COPD animals infected with Pneumocystis, while mucus levels were notably higher in the airways of COPD-infected animals. Interestingly, a CREB responsive element (CRE) was identified in the Muc5b promoter. The presence of CREB in the Muc5b promoter was synergistically increased in COPD animals infected with Pneumocystis compared to other experimental groups. Finally, an increment of deposited collagen was identified surrounding the airways of COPD animals infected with Pneumocystis compared with the other experimental animal groups and correlated with the increase of Tgfβ1 mRNA levels. These findings emphasize the role of Pneumocystis as a potential biological co-factor in chronic respiratory diseases like COPD or asthma, warranting new perspectives in the treatment of chronic respiratory diseases.
