To further test the effect of CSP or CSP7 on glucose metabolism, mice with adenoviral vector–expressing constitutively active TGF-β1–induced (Ad–TGF-β1–induced) established pulmonary fibrosis were daily exposed to CSP or CSP7 by i.p. injection for 2 weeks starting 14 days after Ad–TGF-β1 transduction (Figure 6A). Here, TGFB1 is linked to pulmonary fibrosis.
