Development of all CD4 T lineages requires nuclear factor TOX
CD8(+) cytotoxic and CD4(+) helper/inducer T cells develop from common thymocyte precursors that express both CD4 and CD8 molecules. Upon T cell receptor signaling, these cells initiate a differentiation program that includes complex changes in CD4 and CD8 expression, allowing identification of transitional intermediates in this developmental pathway. Little is known about regulation of these e...
متن کاملTOX is required for development of the CD4 T cell lineage gene program.
The factors that regulate thymic development of the CD4(+) T cell gene program remain poorly defined. The transcriptional regulator ThPOK is a dominant factor in CD4(+) T cell development, which functions primarily to repress the CD8 lineage fate. Previously, we showed that nuclear protein TOX is also required for murine CD4(+) T cell development. In this study, we sought to investigate whether...
متن کاملDevelopment of neuroendocrine lineages requires the bHLH-PAS transcription factor SIM1.
The bHLH-PAS transcription factor SIM1 is expressed during the development of the hypothalamic-pituitary axis in three hypothalamic nuclei: the paraventricular nucleus (PVN), the anterior periventricular nucleus (aPV), and the supraoptic nucleus (SON). To investigate Sim1 function in the hypothalamus, we produced mice carrying a null allele of Sim1 by gene targeting. Homozygous mutant mice die ...
متن کاملThe T Cell Leukemia Oncoprotein SCL/tal-1 Is Essential for Development of All Hematopoietic Lineages
The T cell leukemia oncoprotein SCL/tal-1, a basic-helix-loop-helix transcription factor, is required for production of embryonic red blood cells in the mouse yolk sac. To define roles in other lineages, we studied the hematopoietic potential of homozygous mutant SCL/tal-1 -/- embryonic stem cells upon in vitro differentiation and in vivo in chimeric mice. Here we show that in the absence of SC...
متن کاملInnate lymphoid cell development requires TOX-dependent generation of a common ILC progenitor
Diverse innate lymphoid cell (ILC) subtypes have been defined, based on effector function and transcription factor expression. ILCs derive from common lymphoid progenitors, although the transcriptional pathways leading to ILC lineage specification remain poorly characterized. Here we demonstrate that transcriptional regulator TOX is required for the in vivo differentiation of common lymphoid pr...
