摘要: Smoking-related emphysema is a chronic inflammatory disease driven by the T(H)17 subset of helper T cells through molecular mechanisms that remain obscure. Here we explored role microRNA miR-22 in emphysema. We found was upregulated lung myeloid dendritic (mDCs) smokers with and antigen-presenting (APCs) mice exposed to smoke or nanoparticulate carbon black (nCB) mechanism involved transcription factor NF-κB. Mice deficient miR-22, but not wild-type mice, showed attenuated responses failed develop after exposure nCB. further controlled activation APCs AP-1 complexes histone deacetylase HDAC4. Thus, critical regulator both responses.
