Study evaluating striatal and hippocampal tissues between Helios full knockout and wild type mice

Project description:Striatal and hippocampal tissues were dissected out from wild type and helios knockout mice to perform comparisions by pairs of genotypes. First the comparision between wild type and helios knockout mice using striatal tissues and the second comparision was made between wild type and helios knockout hippocampal tissues

RNA sequencing of CD4+ and CD8+ subsets of human engineered regulatory T cell lines expressing FOXP3, FOXP+Helios-FL, FOXP3+Helios-Δ3b

Project description:We report RNA sequencing data for three human engineered regulatory T cell lines expressing FOXP3, FOXP+Helios-FL, FOXP3+Helios-Δ3b. From total RNA from 3 biological replicates from each cell line, we generated RNA Sequencing data that compared gene expression between CD4+ and CD8+ cells for each cell line. RNA Sequencing demonstrated that the addition of full-length Helios changed gene expression in cellular pathways and the Treg signature compared to FOXP3 alone or the other major Helios isoform.

The Role of a Non-Canonical Splice Variant of the Helios Gene in the Differentiation of Jurkat T Lymphoblasts

Project description:In this study, the ectopic overexpressions of the wild-type Helios-1, non-canonical short isoforms Helios-Δ190-1186, Helios-Δ326-1431, and control in the Jurkat cells were utilized as the routine in vitro model of the T-cell acute lymphoblastic leukemia (T-ALL). We compared the microarray data for transcriptional analysis of the Jurkat cells with stable overexpression of full-length Helios-1, non-canonical short isoforms Helios-Δ190-1186, Helios-Δ326-1431, and mock transfected control.

Influence of ATL-type Helios overexpression or WT-Helios/Ikaros knockdown on gene expression profile in Jurkat cells

Project description:It has been known that aberrant isoforms of Ikaros family ptoteins are expressed in malignant cells. We identified that PBMC of ATL (acute T-cell leukemia) patients expresses different patterns of Helios isoforms compared with normal PBMC. In order to investigate the biological impact of ATL-type Helios isoform, we conducted complehensive gene expression analyses in Jurkat cells overexpressing ATL-type Helios. Also, we investigated the influence of WT-Helios or WT-Ikaros knockdown on the gene expression profile and compared with that of the cells with ATL-type Helios overexpression. Total RNA samples from Jurkat cells were subjected to Cy-3 labeling followed by human whole genome gene expression microarray analyses.

Helios expression defines two distinct populations of Foxp3+ Treg cells

Project description:The transcription factor Helios is expressed in a large subset of Foxp3+ Tregs of both mouse and man. We previously demonstrated that Treg induced in peripheral sites (pTreg) from Foxp3- T conventional (Tconv) cells were Helios- and proposed that Helios is a marker of thymic derived Treg (tTreg). To compare the two Treg subpopulations, we generated Helios-GFP reporter mice and crossed them to Foxp3-RFP reporter mice. The Helios+ Treg population expressed a more activated phenotype and had a higher suppressive capacity in vitro. Both populations expressed a highly demethylated TSDR and both subsets were equivalent in their ability to suppress inflammatory bowel disease in vivo. However, Helios+ Treg more effectively inhibited the proliferation of activated, autoreactive splenocytes from scurfy mice. When Helios+ and Helios- Treg were transferred to lymphoreplete mice, both populations maintained comparable Foxp3 expression, but Foxp3 expression was less stable in Helios- Treg when transferred to lymphopenic mice. Gene expression profiling of the two populations demonstrated a large number of differentially expressed genes and that Helios- Treg subpopulation expressed certain genes normally expressed in CD4+Foxp3- T cells. TCR repertoire analysis indicated very little overlap between Helios+ and Helios- Treg. Thus, Helios+ and Helios- Treg subpopulations are phenotypically and functionally distinct, consistent with thymic and peripheral sites of origin, respectively. Because of their superior suppressive activity and enhanced stability Foxp3+Helios+ Treg represent the optimal Treg population for cellular immunotherapy.
