Keyword(s): Prognostic Factors . Mitochondria are required for pro-ageing features of the senescent phenotype. This reinforces the idea that the development of pulmonary fibrosis is more frequent in people who have been smokers or have been exposed to other substances that damage the alveolar epithelium. Clarifying these questions is crucial to the development of points of intervention in the pathogenesis of the disease. When the air sacs of the lungs called alveoli gets stiff or thick due to scarring, the oxygen supply to the bloodstream gets difficult that causes pulmonary fibrosis. The disease may get worse quickly (over months) or very slowly (over years). Idiopathic pulmonary fibrosis (IPF) is the most common and most lethal type of idiopathic interstitial pneumonia.
