Protein Misfolding and Endoplasmic Reticulum Stress in Chronic Lung Disease

The pathogenesis of chronic lung disorders is poorly understood but is often thought to arise because of repeated injuries derived from exposure to exogenous or endogenous stress factors. Protein-misfolding events have been observed in a variety of genetic and nongenetic chronic lung disorders and may contribute to both the initiation and the progression of lung disease through endoplasmic reticulum (ER) stress and activation of the unfolded …
