Brief Summary:
The main objective of this project is to identify mechanisms for lung regeneration in patients with COPD induced by exercise training The hypothesis is that adjusted exercise training improves disease outcome in these patients by decrease remodelling processes linked to oxidative stress inflammatory andor immunological pathways in the lung Along the way the investigator also expect to identify or validate biomarkers mirroring systemic processes such as reduced inflammation and ameliorating the epithelial barrier in these patients These events may additionally act as potential targets for interventions
Objectives i Evaluate biomarkers for regenerative processes matrix turnover stem cell activity and inflammatory patterns in lung tissue biopsies blood- and urine samples correlated to vital lung parameters and physical capacity before and after attending an exercise-training program
ii Study the effects of exercise training on the pulmonary ventilationperfusion ratio and quality of life
iii Evaluate the relation between pathophysiology in the lung evaluated by CT scan and systemic response measured by muscle biopsies and biomarkers in bloodurine
iv Investigate in vitro cell behaviour and remodellingregenerative processes altered in COPD patients upon exercise training aim 1

Detailed Description:
Chronic obstructive pulmonary disease COPD is an increasing worldwide health problem characterized by progressive destruction of lung tissue In the shadow of the pandemic COPD patients may suffer more severely from COVID-19 with worse prognosis and higher mortality rate This may be due to common underlying risk factors such as smoking cardiovascular disease and a sedative life style To cope with the soaring burden on the health care system posed by the aftermath of the pandemic in the context of chronic diseases such as COPD the importance of self-responsibility to increase quality of life is emerging New guidelines from the 2020 GOLD Science Committee Report on COVID-19 and Chronic Obstructive Pulmonary Disease support exercise in the management of COPD and after COVID-19 infection even during mild COVID-19 symptoms However little is known about the molecular alterations induced by exercise training and how to boost the bodys ability to halt disease progression in COPD
The hypothesize is that adjusted exercise training increases the ability to cope with biological stress which is increased in COPD due to ie chronic inflammation and a history of smoking and may facilitate restoration of damaged tissue In this proposal the anticipation is to link the effects of physical exercise to amelioration of vital lung parameters physical strength including 6 min walk test and quality of life by evaluating biomarkers for stem cell activity regeneration and inflammation in lung tissue biopsies and blood samples This will also result in the recognition of pathways that are targetable for novel pharmaceuticals that could synergize with the training effect
