This study demonstrates our ability to deliver a novel antifibrotic antibody to the lung and provides preliminary evidence that this biologic may be effective in the treatment of pulmonary fibrosis.

Snyder, and Ross SummerLipid synthesis is required to resolve ER stress and limit fibrotic responses in the lung Am J Respir Cell Mol Biol. 2018.

This study provides a unifying mechanism linking ER stress to the development of pulmonary fibrosis. We show that metabolic dysfunction, namely the impairment of lipid synthesis, reduces the capacity of alveolar epithelial cells to resolve ER stress, leading to sustained cellular dysfunction and induction of fibrotic responses. We also provide evidence that pharmacological or dietary approaches to increasing lung lipids could be effective in treating pulmonary fibrosis.

This study is the first to suggest that macrophage foam cells play a causal role in the development of pulmonary fibrosis and that strategies aimed at blocking their formation might be effective in limiting the onset and progression of disease.
