Project description:Disruptions of microbiota composition by factors such as genetics have been suggested to be critical contributing factors to the growth of the worldwide epidemics of chronic illness such as metabolic diseases. IL-35-producing regulatory B and T regulatory cells are critical regulators to these illnesses. Whether microbiota-derived metabolites can regulate these IL-35+ cells maintain elusive. Here, we found gut genetic factor Reg4 associated lactobacillus could promote the generation of IL-35+ B cells through producing 3-idoleacetic acid (IAA). HuREG4IEC tg mice had markedly accumulation of IL-35+ not only in adipose tissues but also in colon tissues; whereas significantly decreased IL-35+ cells in adipose tissues and colon tissues could be detected in Reg4 KO mice. On the mechanism, IAA-mediated IL35+ B cells was through PXR), RXR and CAR in the presence of LPS. PXR KO, CAR KO and NF-B KO mice impaired the generation of IAA- IL-35+B cells. Interestingly, lower levels of IAA and IL-35 were also detected in the peripheral blood of individuals with obesity. Thus, IAA is a factor to promote the generation of IL-35+B cells to impede the development of obesity.
Project description:modENCODE_submission_3213 This submission comes from a modENCODE project of Michael Snyder. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We are identifying the DNA binding sites for 300 transcription factors in C. elegans. Each transcription factor gene is tagged with the same GFP fusion protein, permitting validation of the gene's correct spatio-temporal expression pattern in transgenic animals. Chromatin immunoprecipitation on each strain is peformed using an anti-GFP antibody, and any bound DNA is deep-sequenced using Solexa GA2 technology. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq.
