The Aging Lung and Idiopathic Pulmonary Fibrosis

Swati Gulati et al. Am J Med Sci. 2019 May.

Abstract

Idiopathic pulmonary fibrosis (IPF) is one of many clinical syndromes that are associated with aging, and is increasing in both incidence and prevalence with the rapid rise in aging populations world-wide. There is accumulating data on how the biology of aging may influence the susceptibility to lung fibrosis in the elderly. In this review, we explore some of the known "hallmarks of aging," including telomere attrition, genomic instability, epigenetic alterations, loss of proteostasis, cellular senescence and mitochondrial dysfunction in the pathobiology of IPF. Additionally, we discuss age-associated alterations in extracellular matrix that may contribute to the development and/or progression of IPF.
