Title: Pharmaceutical composition for preventing or treating tuberculous pleural fibrosis
Inventor: HONG JI YOUNG
IPC: A61P11/00
Filed: 2018-08-22
Abstract: According to the present invention, a pharmaceutical composition for preventing or treating tuberculous pleural fibrosis includes phNOX4 inhibitor. Tuberculous pleurisy often causes pleural fibrosis which causes respiratory failure. NOX (NADPH oxidase) enzymes provide hemostasis and host defenses in lungs. However, the role of NOX4 signaling in tuberculous pleurisy is unknown. The present inventors have investigated the role of NOX4 signaling in tuberculous pleural fibrosis by using an in a vitro pleural epithelial cell experiment and a BCG pleural infection mouse model. The result of the study suggests that thermally treated and killed Mycobacterium tuberculosis in pleural mesothelial cells induces NOX4-ROS production and epithelial mesenchymal migration. TLR4 inhibitors, TAK-242 and losartan, reduced NOX4-ROS production and subsequent fibrosis. SiRNA NOX4 pretreatment in cultured pleural epithelial cells inhibited thermally treated and killed Mycobacterium tuberculosis-induced collagen-1 synthesis and epithelial mesenchymal migration. NOX4 mediates thermally treated and killed Mycobacterium tuberculosis-induced epithelial mesenchymal migration and reactive oxygen species production in cells through activation of ERK signaling. In the BCG-induced pleurisy model, a BCG + SiNOX4 group (SiNOX4 IV posttreatment after BCG) reduced inflammatory pleural cell recruitment, inflammatory cytokine release, and mesenchymal fibrosis compared to a BCG + SiCon group (SiCon IV posttreatment after BCG). The results indicate that NOX4-ERK-ROS regulates thermally treated and killed Mycobacterium tuberculosis-induced pleural fibrosis through TLR4 and AT1R. NOX4 may be a new therapeutic target in tuberculous pleural fibrosis.
