Bach2 keeps homeostasis in lung by regulating inflammatory response and maintaining function of alveolar macrophage.. Mus musculus

Alveolar macrophages (AMs) of Bach2 KO mice show multiple alternations in their functions including lipid metabolism. We aimed to clarify the mechanism whereby deficiency of Bach2 impairs the function of AMs and ruins the homeostasis of lungs. Now we report that some cytokines produced from Bach2-deficient T cells alter the character of AMs and expression of Bach2 is necessary for AMs to maintain the function of lipid metabolism. Overall design: mRNA profiling of AMs from 16-week old control mice, Bach2-floxed CD4cre mice, WT mice and Bach2 germline KO mice were examined by deep sequencing using HiSeq2500. Please note that two macrophage populations observed in Bach2-floxed/CD4-cre cKO mice were analyzed; One with normal surface marker phenotype that was the same as control mice (normal). The other with aberrant surface marker phenotype compared with control mice (abnormal).
