Title: Transcription profiling by array of mouse peripheral wild-type and HDAC1/2-null CD4+ T cells to investigate redundant and non-redundant functions of HDAC1 and HDAC2

description:
Dynamic changes in histone acetylation patterns are mediated by the activity of histone acetyltransfereases (HATs) and histone deacetylases (HDACs) and are key events in the epigenetic regulation of gene expression. The application of HDAC inhibitors revealed a variety of T cell functions controlled by reversible lysine acetylation and HDAC1, HDAC2, HDAC3, HDAC7 and HDAC9 have been implicated in regulating T cell development and function. Nevertheless, unique functions of individual HDAC members in T cells and specific T cell functions that are regulated by HDACs are still only poorly understood. We previously showed that T cell-specific loss of HDAC1 (using the Cd4Cre deleter strain) leads to enhanced allergic airway inflammation and increased Th2 cytokine production. Interestingly, late T cell development was not impaired in these mice. However, HDAC2 was up-regulated in the absence of HDAC1, thus we hypothesized compensatory pathways/function between these two closely related class I HDAC family members in T cells. To investigate redundant and non-redundant functions of HDAC1 and HDAC2, we generated mice with a conditional T cell-specific (using Cd4Cre) combined loss of HDAC1 and HDAC2. As part of our study, we determined and compared the transcriptome of peripheral wild-type and HDAC1/2-null CD4+ T cells. Since loss of HDAC1/HDAC2 during late T cell development led to the appearance of MHC class II-selected CD4+ helper T cells that expressed CD8 lineage genes such as Cd8a and Cd8b1, we also analyzed the transcriptome of HDAC1/2-null CD4+CD8+ T cells.
