IFNb/LPS activates convergence of inflammatory gene expression patterns between adipocytes and myeloid cells.
We examined the transciptomic changes to primary adipocytes resulting from exposure to IFNb and/or LPS, in order to define the mechanisms driving adipocyte inflammatory capacity and resulting transcriptomic convergence with iinflammatory myeloid cells. Inguinal adipose tissue was obtained from 8 weeks old aged male C57BL/6 mice and stromal vascular fraction was maximally differentiated into primary adipocytes.  Cultured cells were treated with IFNb (200U/ml) or saline for 3 hours and thereafter with LPS (100ng/ml) or saline for 4 hours and then submitted for RNA-sequencing. Results: We mapped approximately 20 million reads per sample to the mm10 genome, and analyzed all transcripts with >3 reads in 100% of at least one experimental condition. Overall design: Our study characterizes the transcriptional changes induced by IFNb, LPS and IFNb+LPS through RNAsequencing of adipocytes.  Our results identify that IFNb unlocks a convergence in gene expression patterns between adipocytes and myeloid cells. Further, IFNb priming augments LPS-induced pathways in adipocytes.
