Transcriptional profiling of Regulatory T-cells isolated from adult skin and skin draining lymph nodes (SDLNs)

ABSTRACT: Purpose: The goals of this study were to identify preferential gene expression signatures that are unique to telogen skin resident Tregs relative to peripheral Tregs Methods: Tregs from telogen skin and SDLNs were purified by cell sorting (using the Treg GFP reporter mouse line Foxp3-DTR/GFP) to generate mRNA transcription profiles. Results: Transcriptional profiling revealed a unique Skin treg signature relative to SDLN Tregs Conclusion: Our study represents the first detailed analysis of the skin Treg transcriptome. mRNA profiles of skin and SDLN Tregs isolated from 6 week old Foxp3-DTR/GFP mice.

Transcriptional profiling of hair follicle stem cells in the presence and absence of Regulatory T-cells

Project description:Purpose: The goals of this study were to identify Pathways that Tregs utilize in the skin to maintain tissue homesostasis in the context of hair follcile cycling. Methods: Hair follicle stem cells (HFSCs), in the presence and absence of Tregs, were induced into cycle through a model of depilation induced anagen. HFSCs were then purified by cell sorting at day 4 post depilation based on cell surface marker expression (CD45 negative, MHC Class II negative, Sca-1 negative, EpCAM negative, CD34 Positive, Integrin alpha6 High) to generate mRNA transcription profiles. Results: Transcriptional profiling revealed a significant reduction in proliferation/differentiation associated genes expressed in HFSCs isolated from Treg depleted mice Conclusion: Our study represents the first detailed analysis of Treg modulation of tissue stem cell behaviour mRNA profiles of HFSC isolated from 7-10 week old WT and Foxp3-DTR mice at 4 days post depilation of dorsal skin.

Genome-wide profiling of 2 month vs >6 month old muscle Treg cells

Project description:We report age-related gene expression of Treg cells isolated from injured muscle and spleen. Male C57BL/6 Foxp3-GFP reporter mice were injured intramuscularly with cardiotoxin. Tregs were sorted directly into Trizol from injured muscle and spleen 4 days post-injury. Gene expression profiling of muscle and splenic Tregs from 2- vs >6-month old mice (biological duplicate for each).

Regulatory T cells from colonic lamina propria [array]

Project description:The colonic lamina propria contains a distinct population of Foxp3+ T regulatory cells (Tregs) that modulate responses to commensal microbes. Analysis of gene expression revealed that the transcriptome of colonic Tregs is distinct from splenic and other tissue Tregs. Rorγ and Helios in colonic Tregs mark distinct populations: Rorγ+Helios- or Rorγ-Helios+ Tregs. We uncovered an unanticipated role for Rorγ, a transcription factor generally considered to be antagonistic to Foxp3. Rorγ in colonic Tregs accounts for a small but specific part of the colon-specific Treg signature. (1) Total colonic and splenic Foxp3+ Treg comparison: Lymphocytes were isolated from colonic lamina propria and spleens of Foxp3-ires-GFP mice, where GFP reports Foxp3 expression. TCRb+CD4+GFP+ cells were double sorted into Trizol. (2) Colonic Rorγ+ and Rorγ- Treg comparison: Foxp3-ires-Thy1.1 reporter mice were crossed to Rorc-GFP reporter mice to generate mice that report both Foxp3 and Rorγ expression. Rorγ+Foxp3+ Tregs (TCRb+CD4+Thy1.1+GFP+) and Rorγ-Foxp3+ Tregs (TCRb+CD4+Thy1.1+GFP-) from colonic lamina propria were double sorted into Trizol.To reduce variability and increase cell number, cells from multiple mice were pooled for sorting and at least three replicates were generated for all groups. RNA from 1.5-3.0 x104 cells was amplified, labeled and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays.

Gene expression profiling of Bone Marrow FoxP3+ Treg cells

Project description:Gene expression profiling of Bone Marrow FoxP3+ Treg cells. Glatman Zaretsky et al. revealed an unexpected role for Tregs in plasma cell biology. Here we determined the gene-expression profile of this new subset of FoxP3+ Treg cell, which express high levels of Treg effector molecules, similar to other non-lymphoid tissue Tregs. Gene-profiling of BM Tregs. Bone marrow Treg cells (30k) (gfp+CD25hiCD4+TCRÎ²+) (dump negative: CD19-CD8Î±-TCRÎ³Î´-CD11b-CD11c-NK1.1-Gr-1-Ter-119-) were triple-sorted from pools of two to three reporter mice (C57BL/6 Foxp3-IRES-gfp, 9 week-old males) into trizol per ImmGen SOP. RNA was amplified, labeled and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays (Expression Analysis)

Effect of Amphiregulin on global gene expression in injured skeletal muscle in the presence or absence of CD4+Foxp3+ regulatory T cells (Tregs).

Project description:Global gene expression analysis of injured skeletal muscle showed that amphiregulin (Areg), a growth factor over-expressed by muscle Treg cells, enhances muscle regeneration both in the presence and in the absence of Tregs. Foxp3-DTR+ and Foxp3-DTR- mice were injured with cardiotoxin in TA muscle at day 0 and treated with diphtheria toxin every other day from day 0 until dissection. Amphiregulin or PBS were administered im on day 0 and ip every other day until dissection. TA muscle was flash-frozen and RNA was extracted using Trizol. RNA from whole tissue samples was amplified, labeled, and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays.

Gene expression profiling of injured skeletal muscle in the presence or absence of CD4+Foxp3+ regulatory T cells (Tregs).

Project description:A comparative analysis of gene expression of injured skeletal muscle from wild-type (Foxp3-DTR-) and Treg-depleted (Foxp3-DTR+) mice showed that Treg cells are critical for effective repair and regeneration of acute injury of skeletal muscle. Foxp3-DTR+ and Foxp3-DTR- mice were injured with cardiotoxin in TA muscle at day 0 and treated with diphtheria toxin every other day from day 0 until dissection on day 4 or 8. TA muscle was flash-frozen and RNA was extracted using Trizol. RNA from whole tissue samples was amplified, labeled, and hybridized to Affymetrix Mouse Gene 1.0 ST Arrays.
