Study: Multi-omics approaches reveal TNF-mediated inhibition of tissue reparative macrophages is via a gene-selective transcriptional mechanism (ATAC-Seq)
show Abstracthide Abstract
Anti-TNF therapies are a core anti-inflammatory approach for chronic diseases such as rheumatoid arthritis and Crohn's Disease. Previously, we and others found that TNF blocks the emergence and function of alternatively-activated or M2 macrophages involved in wound healing and tissue-reparative functions. Conceivably, anti-TNF drugs could mediate their protective effects in part by an altered balanced of macrophage activity. To understand the mechanistic basis of how TNF regulates tissue-reparative macrophages we used RNAseq, scRNAseq, ATACseq, time-resolved phospho-proteomics, gene-specific approaches, metabolic analysis and signaling pathway deconvolution. Our findings reveal that TNF controls tissue-reparative macrophage gene expression in a highly gene-specific way dependent on JNK signaling. We uncover principles of the selectively inhibition by TNF via the type 1 TNF receptor on specific populations of alternative activated macrophages. Overall design: Chromatin accessibility profiles of wild-type BMDMs stimulated with IL4/IL13 or IL4/IL13 + TNF for 24h from 3 separate mice.

Layout: PAIRED
Construction protocol: BMDMs treated as described were washed in PBS and then lysed in 10 mM Tris-HCl, pH 7.4,10 mM NaCl, 3 mM MgCl2 and 0.1% Igepal CA-630 (all Sigma). Nuclei were then spun down and then resuspend in 25 l TD (2x reaction buffer), 2.5 L TDE1 (Nextera Tn5 Transposase) and 22.5 L nuclease-free water, incubated for 30 min at 37°C. DNA was purified with the Qiagen MinElute PCR Purification Kit (Thermo Fisher Scientific). Libraries were prepared using the Nextera DNA library Prep Kit (Illumina) adapting a published protocol (Buenrostro et al., 2015). PCR amplification was performed with the NEBNext High-Fidelity 2x PCR Master Mix (New England Labs) using custom Nextera PCR Primers containing barcodes. Adaptors were removed with AMPure XP beads according to manufacturer's protocol.
