Idiopathic Pulmonary Fibrosis is a Genetic Disease Involving Mucus and the Peripheral Airways
Year: 2018
Type: review
Abstract: Idiopathic pulmonary fibrosis (IPF) is localized to the lung, is characterized by a pattern of heterogeneous, subpleural patches of fibrotic, remodeled lung, and is associated with a median survival of 3-5 years after diagnosis. A common gain-of-function MUC5B promoter variant, rs35705950, is the strongest risk factor (genetic and otherwise), accounting for at least 30% of the total risk of developing IPF. The MUC5B promoter variant can be used to identify individuals in the preclinical phase of this progressive disease, and, in the IPF lung, we have found that MUC5B is specifically overexpressed in bronchoalveolar epithelium. Thus, MUC5B represents a key molecule to understand the mechanisms that appear to initiate the fibroproliferative process in the bronchoalveolar epithelium. Moreover, focusing on MUC5B may provide a unique opportunity to define the early molecular events that lead to, and potentially prevent, the development of IPF.
