Single-cell RNA sequencing (scRNA-Seq) analysis of tumor-infiltrating lymphocytes (TILs) from B16-F0 melanoma in mice

ABSTRACT: To comprehensively analyze the influences on the tumor infiltrated immune cells after deficiency of APPL2 specifically in Tregs, we employed single-cell RNA sequencing (scRNAseq) to profile CD45+ TILs from both Foxp3YFP-Cre Appl2f/f and Foxp3YFP-Cre control mice. To our surprise, tumor infiltrated B cells were dramatically decreased in Foxp3YFP-Cre Appl2f/f mice. Hereby, there was a trend of increase for most of the other immune subsets. These data indicated that the infiltrated B cells, as a whole, were tumor supportive and restricting protumoral B cell infiltration was critical for Appl2-KO Tregs in suppressing tumor growth.

Steroid nuclear receptor coactivator 2 controls immune tolerance by promoting induced Treg differentiation via upregulating Nr4a2

Project description:Purpose:Steroid nuclear receptor coactivator 2 (SRC2) is a member of family of transcription co-activators. While SRC1 inhibits the differentiation of regulatory T cells (Tregs) critical for establishing immune tolerance, we show here that SRC2 stimulates Treg differentiation. SRC2 is dispensable for the development of thymic Tregs, whereas naïve CD4+ T cells from mice deficient of SRC2 specific in Tregs (SRC2fl/fl/Foxp3YFP-Cre) display defective Treg differentiation. Furthermore, the aged SRC2fl/fl/Foxp3YFP-Cre mice spontaneously develop autoimmune phenotypes including enlarged spleen and lung inflammation infiltrated with IFNγ-producing CD4+ T cells. SRC2fl/fl/Foxp3YFP-Cre mice also develop severer experimental autoimmune encephalomyelitis (EAE) due to reduced Tregs. Mechanically, SRC2 recruited by NFAT1 binds to the promoter and activates the expression of Nr4a2 which then stimulates Foxp3 expression to promote Treg differentiation. Members of SRC family co-activators thus play distinct roles in Treg differentiation and are potential drug targets for controlling immune tolerance

The chromatin-modifying enzyme Ezh2 is a CD28-dependent molecule critical for the maintenance of Treg identity

Project description:Regulatory T cells (Tregs) are essential for maintaining proper immune homeostasis. Extracellular signals (e.g. TCR, CD28, IL-2R) are necessary for the generation and maintenance of Tregs, but how these signals are integrated to control the gene expression patterns of Tregs is less clear. Here we show that the epigenetic regulator, Ezh2, was induced by CD28 costimulation and Ezh2 activity was elevated in Tregs as compared to conventional CD4+ T cells. Deletion of Ezh2 in mouse Tregs led to a progressive autoimmune disease because Tregs were compromised after activation, losing proper control of essential Treg lineage genes and adopting a gene expression pattern similar to Foxp3-deficient ‘Tregs.’ Lineage-tracing of Ezh2-deficient Tregs in vivo confirmed that the cells were destabilized selectively in activated Treg populations, which led to a significant loss of Tregs in non-lymphoid tissues. These studies reveal an essential role for Ezh2 in the maintenance of Treg “identity” during cellular activation and differentiation. RNAseq of sorted populations of CD62Lhi or CD62Llo Tregs for both Ezh2-HET (Foxp3YFP-Cre/Foxp3WT;Ezh2fl/+ female mice) and Ezh2-KO (Foxp3YFP-Cre/Foxp3WT;Ezh2fl/fl female mice) were generated, in triplicate for each condition, using Illumina HiSeq 2500 single-end 50bp sequencing platform.

Cancer-associated SF3B1-K700E mutation controls immune responses by regulating Treg function via aberrant Anapc13 splicing

Project description:Recurrent somatic mutations in spliceosome factor 3b subunit 1 (SF3B1) are identified in hematopoietic cell-derived malignancies, with SF3B1-K700E being the most common one. Here we show that Treg specific expression of SF3B1-K700E (Sf3b1K700Efl/+/Foxp3YFP-Cre) results in spontaneous autoimmune phenotypes including enlarged spleen and tissue infiltration with IFN-γ-producing CD4+ T cells. CD4+ T cells from Sf3b1K700Efl/+/Foxp3YFP-Cre mice display defective Treg differentiation and inhibitory function, which is demonstrated by failed prevention of adoptive transfer colitis by Sf3b1K700Efl/+/Foxp3YFP-Cre Tregs. Mechanically, SF3B1-K700E induces an aberrant splicing event that results in reduced expression of a cell proliferation regulator Anapc13 due to insertion a 231 bp DNA fragment to the 5’ untranslated region (UTR). Forced expression of Anapc13 gene restores the differentiation and ability of Sf3b1K700Efl/+/Foxp3YFP-Cre Tregs to prevent adoptive transfer colitis. Our results thus highlight the impact of a hematological malignancy-associated SF3B1 mutation on immune responses and indicate a potential relationship between splicing factor mutation-dysregulated immune responses and cancer development.

Wnt/β-catenin activation epigenetically reprograms Regulatory T cells in IBD and progression to dysplasia

Project description:Previous work indicated that β-catenin/TCF-1 occupy DNA together with Foxp3. Thus, we anticipated that precise mapping of TCF-1 and Foxp3 co-binding in Tregs, could provide a molecular explanation for our phenotypic observations. To address this, we analyzed TCF-1 DNA binding in Tregs through chromatin immunoprecipitation and deep sequencing (ChIPseq) in Foxp3YFP-Cre WT Tregs. Furthermore, we assessed regions of accessible chromatin in Tregs via transposase-accessible chromatin approach and deep sequencing (ATAC-seq). We also performed RNA-seq expression profiling to investigate how the changes in chromatin accessibility impacted transcription in β-catenin high Tregs.

Transcriptomic profiling of tumor-infiltrating and lymph node-derived Treg and B cells in Foxp3-Cre-YFP and Foxp3-Cre-YFP Appl2f/f melanoma-bearing Mice

Project description:Tregs are a critical target for developing anti-tumor immunotherapy, however, they are also critical for maintaining systemic immune tolerance and homeostasis. It remains a formidable challenge to specifically disable Tregs in the tumor microenvironment without compromising systemic immune tolerance. An ideal target is that barely expressed or dispensable in peripheral Tregs but significantly increased and critical for the immunosuppressive activity of tumor infiltrated Tregs (TIL-Tregs). In an attempt to search for specific targets that mediate TIL-Tregs fitness in the tumor microenvironment, we performed RNA-seq of TIL-Tregs and Tregs from the draining lymph nodes (dLN-Tregs) of mice bearing B16-F0 melanoma.

TSLP acts on Tregs to limit allergic inflammation and to maintain Treg identity

Project description:Thymic stromal lymphopoietin (TSLP) is a type I cytokine that promotes allergic responses and mediates type 2 immunity. A balance between effector T cells (Teff), which drive the immune response, and regulatory T cells (Tregs), which suppress the response, is required for proper immune homeostasis. Here, we report that TSLP differentially acts on Teff versus Tregs to balance type 2 immunity. As expected, deletion of TSLPR on all T cells (Cd4CreCrlf2fl/fl mice) resulted in lower numbers of Th2 cells and diminished ovalbumin-induced airway inflammation, but selective deletion of TSLPR on Tregs (Foxp3YFP-Cre/YCrlf2fl/fl mice) resulted in increased IL-5- and IL-13-secreting Th2 cells and lung eosinophilia. Moreover, TSLP augmented the expression of factors that stabilize Tregs, and remarkably, during type 2 immune responses, TSLPR-deficient Tregs acquired Th2-like properties, with augmented levels of GATA3 and secretion of IL-13. Thus, TSLP not only is a driver of Th2 effector cells, but it also acts in a negative feedback loop, promoting the ability of Tregs to limit allergic inflammation.

Transcriptome analysis of OGT-sufficient and OGT-deficient regulatory T (Treg) cells

Project description:To gain comprehensive insight into the OGT-dependent transcriptional program in Treg cells, we performed RNA-sequencing of isolated YFP+ Treg cells from Foxp3YFP-Cre/wtOgtwt/fl and healthy Foxp3YFP-Cre/wtOgtfl/fl females to avoid secondary changes in gene expression caused by inflammation. We were able to identify 269 differentially expressed genes including 154 downregulated and 115 upregulated with p values less than 0.01, OGT-deficient Treg cells had impaired suppressive function and attenuated IL2/STAT5 signaling pathway.

RNA-seq of T in PBMC and TILs

Project description:Purpose: Transcriptome profiling (RNA-seq) was used to compare the expression differences between T in PBMC and TILs Methods:Paired TILs and T in PBMC cells were sorted from fresh patient blood and tumor samples. Then the mRNA were sequeced using xTen platform. The sequence reads that passed quality filters were analyzed. Results: by extract mRNA from tumor infiltrated T cells from ovarian cancer patient sample and T cells from patient bllod samples, we compared the different expressed genes from TIL and T in blood. Hierarchical clustering of differentially expressed genes uncovered several as yet uncharacterized genes that may contribute to T cell exhausetion. Conclusions: We conclude that T in PBMC and TILs share different transcriptome characterization.
