IL-4-activated C/EBPβ is involved in alveolar macrophage polarization towards the M2 phenotype during pulmonary fibrosis induced by single-walled carbon nanotubes

IL-4-activated C/EBPβ participated in SWCNT-mediated M2 AM polarization and fibrogenesis, and IL-4 may serve a therapeutic target for nanoparticle-induced fibrogenesis.
