Genome-wide analysis of microRNA-22 responsive gene expression in lung antigen presenting cells in response to chronic nanoparticulate carbon black exposure

ABSTRACT: Analysis of lung CD11c+ antigen presenting cells (APCs) isolated from wildtype or Mir22-/- mice exposed to nanoparticulate carbon black (nCB) for one month. MiR-22 plays important roles in nCB induced experimental emphysema through regulating APC activation. Results provide insight into the biological role and target genes of miR-22. Smoking-related emphysema is a chronic inflammatory disease driven by T helper 17 (TH17) cells through molecular mechanisms that remain obscure. Here we have explored the role of microRNA-22 (miR-22) in emphysema. MiR-22 was upregulated in lung myeloid dendritic cells (mDCs) of smokers with emphysema and antigen-presenting cells (APCs) of mice exposed to smoke or nanoparticulate carbon black (nCB) through a mechanism involving NF-kappaB.
