Thpok runx3d

To visualize thymocytes expressing Runx3d mRNA, we generated a reporter allele (Runx3dYFP) by replacing the first coding exon used by the Runx3 distal promoter with sequence encoding yellow fluorescent protein (YFP; Supplementary Fig. 1a online). In accordance with published analyses of Runx protein … See more To visualize ThPOK expression in individual differentiating thymocytes, we generated a green fluorescent protein (GFP)-expressing 'knock-in' allele of ThPOK by replacing all of … See more To determine whether there was cross-regulation of ThPOK and Runx3 during thymocyte lineage specification, we examined expression of the ThPOK and Runx3d reporters in the absence of one or the other factor. … See more Our data indicated a correlation between Runx3 derepression and redirection of MHC class II–restricted thymocytes to the cytotoxic lineage.

WebDec 1, 2024 · In Th1 cells, the upregulation of Runx3d by T-box protein expressed in T cells (T-bet) promotes the differentiation of Th1 cells, inducing the secretion of IFNγ [21]. ... WebIn ThPOK-deficient mice, Runx3d expression was de-repressed in MHCII-selected thymocytes, contributing to their redirection to the CD8 T cell lineage. In the absence of both ThPOK and Runx, redirection was prevented and cells potentially belonging to the CD4 lineage, presumably specified independently of ThPOK, were generated.

WebT cells require Runx3, in particular the Runx3d isoform, which is transcribed from a distal promoter [33, 34]. In terms of genetic interaction, upregulation of Thpok in CD4?8lo intermediates is dependent on Gata3 and Tox [35, 36], and Thpok and Runx3d oppose each other’s transcription/activity to ensure respective lineage promoting effects [37–39] (Fig. 2).
