      Every year, the European Respiratory Society (ERS) organises the Lung Science Conference (LSC) in Estoril, Portugal, to discuss basic and translational science. The topic of the LSC 2020 was “Metabolic alterations in lung ageing and disease”. In addition to an outstanding scientific programme, the LSC provides excellent opportunities for career development and inclusion of Early Career Members (ECMs). All scientific and poster sessions are chaired by an ECM who is paired with a senior faculty member to allow ECMs to become acquainted with session chairing. In addition, 40 travel bursaries are made available to abstract authors and all bursary recipients are invited to take part in a mentorship lunch. Moreover, there is a session organised by the Early Career Members Committee (ECMC) dedicated to career development. Here, we describe the scientific highlights of LSC 2020 for those who could not attend. The ERS presents several awards at the LSC and here we will highlight all winners of the LSC 2020 awards. The five highest ranked abstracts from ECMs are presented during the Young investigator session. Patricia Ogger (UK) was presented with the William MacNee Award for the best presentation in this session. Several abstracts were selected for programmed oral presentations and Renata Jurkowska (UK) was presented with the inaugural Geoffrey Laurent Award for the best oral presentation. Moreover, the organisers presented eight Distinguished Poster awards to Anne-Sophie Lamort (Germany), Julia Frankenberg Garcia (UK), Johnatas Silva (UK), Pauline Esteves (France), Claudio Bussi (UK), Elodie Picard (France), Felix Ritzmann (Germany) and Alen Faiz (Australia) for their excellent contributions during the poster session.
    • Mitochondria: at the crossroads of regulating lung epithelial cell function in chronic obstructive pulmonary disease.

      Disturbances in mitochondrial structure and function in lung epithelial cells have been implicated in the pathogenesis of various lung diseases, including chronic obstructive pulmonary disease (COPD). Such disturbances affect not only cellular energy metabolism but also alter a range of indispensable cellular homeostatic functions in which mitochondria are known to be involved. These range from cellular differentiation, cell death pathways, and cellular remodeling to physical barrier function and innate immunity, all of which are known to be impacted by exposure to cigarette smoke and have been linked to COPD pathogenesis. Next to their well-established role as the first physical frontline against external insults, lung epithelial cells are immunologically active. Malfunctioning epithelial cells with defective mitochondria are unable to maintain homeostasis and respond adequately to further stress or injury, which may ultimately shape the phenotype of lung diseases. In this review, we provide a comprehensive overview of the impact of cigarette smoke on the development of mitochondrial dysfunction in the lung epithelium and highlight the consequences for cell function, innate immune responses, epithelial remodeling, and epithelial barrier function in COPD. We also discuss the applicability and potential therapeutic value of recently proposed strategies for the restoration of mitochondrial function in the treatment of COPD.
