Regulation of ILC2s by Brg1 (CUTandTag)

The alteration of chromatin status critically dictates the expansion and function of group 2 innate lymphoid cells (ILC2s), which have been shown to play a pathogenic role in allergic lung inflammation. In this study, we use multi-omics approaches to dissect the molecular mechanisms of how Brg1 regulates ILC2s in allergic lung diseases through a cell intrinsic manner. Our data indicate that Brg1 regulates ILC2 properties through orchestrating ILC2 energetic metabolism. These findings are enlightening for the understanding of ILC2-mediated pathogenesis in allergic lung inflammation and highlight Brg1 as a potential therapeutic target. Lung ILC2s isolated from naïve wild-type mice, IL-33-treated wild-type mice and Il5Cre/+Smarca4f/f mice as a negative control. Cells were subjected to Brg1 CUT&Tag analysis.
