HiChIP identifies high-resolution chromosome conformation in primary human T cells. (a) Primary T cell H3K27ac HiChIP experimental outline. (b) Left, FACS strategy for naive, TH17, and Treg cells from total peripheral blood CD4+ T cells. Number represents the percentage of total CD4+ T cells within that gate. Right, Knight–Ruiz (KR) matrix–balanced interaction maps for naive, TH17, and Treg cells at 500-kb, 25-kb, and 5-kb resolution, and raw interaction maps at 1-kb resolution, centered on the KLF2, RBPJ, and LRRC32 loci. (c) HiChIP 1D and 3D signal enrichment at the RORC locus in TH17 over naive T cells.
