Translation from endotype to phenotype, variants and comorbidities. Translation from endotype to phenotype, variants and comorbidities. Four main biological networks are involved in idiopathic pulmonary fibrosis (IPF) that include several key elements of the accelerated ageing and lead to the consequent altered wound healing. 1) Cellular network: mesenchymal stem cells (MSCs), alveolar epithelial cells (AECs), extracellular matrix (ECM), fibroblasts, myofibroblasts, macrophages, senescence, mitochondrial dysfunction, apoptosis, autophagy. 2) Metabolic regulation network: hormones, soluble mediators, cell metabolism. 3) Genetic network: MUC5B, SFTPC/SFTPA, telomerase complex, epigenetics. 4) Environmental network: smoking, pollution, gastro-oesophageal reflux (GOR), dust, microbiome. The interconnection among the different players and the clinical repercussions of this complex integrative model is not completely understood. Systems biology is probably the perfect tool to finally shed light on these elusive questions. PAH: pulmonary arterial hypertension. Maria Molina-Molina et al.
