Abstract: Idiopathic pulmonary fibrosis (IPF) is a chronic progressive disease with unknown etiology, which is characterized by scarring of lung parenchyma, leading to reduced quality of life and premature death. At present, some studies have confirmed that hypothyroidism (HT) may play a role in the development of fibrosis. Many animal experiments have proved that thyroid hormone (TH) can inhibit pulmonary fibrosis by regulating glucose metabolism, improving mitochondrial function and inhibiting inflammation. This paper summarizes the correlation between TH and IPF, and deeply understands the relationship between TH and IPF, in order to have new treatment strategies for IPF in the future.

Key words: thyroid hormone, idiopathic pulmonary fibrosis, glucose metabolism, mitochondrion, inflammation
