Innate lymphoid cell (ILC) development proposes that ILC precursors (ILCPs) segregate along natural killer (NK) cell versus helper cell (ILC1, ILC2, ILC3) pathways, the latter depending on expression of Id2, Zbtb16, and Gata3. We have developed an Id2-reporter strain expressing red fluorescent protein (RFP) in the context of normal Id2 expression to re-examine ILCP phenotype and function. We show that bone-marrow ILCPs were heterogeneous and harbored extensive NK-cell potential in vivo and in vitro. By multiplexing Id2RFP with Zbtb16CreGFP and Bcl11btdTomato strains, we made a single-cell dissection of the ILCP compartment. In contrast with the current model, we have demonstrated that Id2+Zbtb16+ ILCPs included multi-potent ILCPs that retained NK-cell potential. Late-stage ILC2P and ILC3P compartments could be defined by differential Zbtb16 and Bcl11b expression. We suggest a revised model for ILC differentiation that redefines the cell-fate potential of helper-ILC-restricted Zbtb16+ ILCPs.

THIS RESOURCE IS NO LONGER IN SERVICE. Documented on May 5,2022.Tool that predicts interactions between transcription factors and their regulated genes from binding motifs. Understanding vertebrate development requires unraveling the cis-regulatory architecture of gene regulation. PRISM provides accurate genome-wide computational predictions of transcription factor binding sites for the human and mouse genomes, and integrates the predictions with GREAT to provide functional biological context. Together, accurate computational binding site prediction and GREAT produce for each transcription factor: 1. putative binding sites, 2. putative target genes, 3. putative biological roles of the transcription factor, and 4. putative cis-regulatory elements through which the factor regulates each target in each functional role.
