IL-32, a Novel Proinflammatory Cytokine in Chronic Obstructive Pulmonary Disease

Abstract

This is the first study to demonstrate increased expression of IL-32 in lung tissue of patients with COPD, where it was colocalized with tumor necrosis factor-alpha and correlated with the degree of airflow obstruction. These results suggest that IL-32 is implicated in the characteristic immune response of COPD, with a possible impact on disease progression.
