Dendritic Cell Fate is Determined by BCL11A

ABSTRACT: Here we confirm an essential requirement for the BCL11A transcription factor in fetal pDC development, and for the first time demonstrate this lineage specific requirement in the adult organism. Genome-wide analyses of BCL11A DNA binding and expression revealed that BCL11A regulates transcription of E2-2 and other pDC differentiation modulators including ID2 and MTG16. Our results identify BCL11A as an essential, lineage-specific factor that regulates pDC development.

Input was sequenced and used as a control.

Dendritic cell fate is determined by BCL11A

Project description:The plasmacytoid dendritic cell (pDC) is vital to the coordinated action of innate and adaptive immunity. pDC development has not been unequivocally traced, nor has its transcriptional regulatory network been fully clarified. Here we confirm an essential requirement for the BCL11A transcription factor in fetal pDC development, and demonstrate this lineage-specific requirement in the adult organism. Furthermore, we identify BCL11A gene targets and provide a molecular mechanism for its action in pDC commitment. Embryonic germ-line deletion of Bcl11a revealed an absolute cellular, molecular, and functional absence of pDCs in fetal mice. In adults, deletion of Bcl11a in hematopoietic stem cells resulted in perturbed yet continued generation of progenitors, loss of downstream pDC and B-cell lineages, and persisting myeloid, conventional dendritic, and T-cell lineages. Challenge with virus resulted in a marked reduction of antiviral response in conditionally deleted adults. Genome-wide analyses of BCL11A DNA binding and expression revealed that BCL11A regulates transcription of E2-2 and other pDC differentiation modulators, including ID2 and MTG16. Our results identify BCL11A as an essential, lineage- specific factor that regulates pDC development, supporting a model wherein differentiation into pDCs represents a primed "default" pathway for common dendritic cell progenitors. Raji cells were infected with retroviruses containing pXY-PURO (negative control vector) or pXY-BCL11A-XS. BJAB cells were infected with retroviruses containing pXY-PURO (negative control vector) or pXY-BCL11A-XL. Two arrays measured Raji BCL11A-XS expression and two arrays measured BJAB BCL11A-XL expression.

Common lymphoid progenitor derivation of plasmacytoid dendritic cells is mediated by Bcl11a

Project description:Plasmacytoid dendritic cells (pDC) specialize in type I interferon production to coordinate innate and adaptive immunity. We identify two pDC subsets in vivo, evaluate their genome-wide expression, and demonstrate a developmental requirement for Bcl11a to provide insight into this enigmatic cell type.

Mtg16 regulates E protein activity and lineage specification in dendritic cell development (gene expression)

Project description:E protein transcription factors specify major immune cell lineages including lymphocytes and interferon-producing plasmacytoid dendritic cells (pDCs). Corepressors of the ETO family can bind to and block transactivation by E proteins, but the physiological role of these interactions remained unclear. We report that ETO protein Mtg16 binds chromatin primarily through the pDC-specific E protein E2-2 in human pDCs. Mtg16-deficient mice showed impaired pDC development and functionality, whereas the specification of the classical dendritic cells (cDCs) was enhanced. The deletion of Mtg16 caused aberrant expression of E protein antagonist Id2 in pDCs. Thus, Mtg16 acts as a cofactor of E2-2 to promote pDC differentiation and restrict cDC development, revealing an unexpected positive role of ETO proteins in E protein activity. pDC from BM of WT and mtg16-KO mice were negatively selected (lin-CD19, Tcrb, Ter119, NK1.1) and sorted as CD11c+Bst2+ population directly in Trizol. RNA was prepared and deposited for microarray processing.
