Hsp104, Hsp90, Hsp70, Hsp60, Hsp47, Hsp40, Hsp32 Etc. are major molecular species of Hsp or cofactors of major molecular species, and when their expression is promoted, a stronger molecular chaperone function of Hsp can be expected.
Pulmonary fibrosis is a condition in which lung tissue becomes fibrotic due to the accumulation of excess collagen and other extracellular matrix. Among them, idiopathic pulmonary fibrosis is a chronic intractable disease with a poor prognosis with a 5-year survival rate of 20 to 40%. In recent years, it has been reported that Hsp is involved in the prevention and treatment of fibrosis of lung tissue (Non-Patent Document 1). Therefore, Hsp expression promoters are useful for the prevention and treatment of pulmonary fibrosis.
