TCR sequencing of Treg and Tconv subsets from murine spleen

ABSTRACT: While unique subsets of Treg cells have been described in some non-lymphoid tissues, their relationship to Treg cells in secondary lymphoid organs and circulation remains unclear. We have identified a recirculating and highly suppressive effector Treg cell subset that expresses the α2 integrin, CD49b, and exhibits a unique tissue distribution. We used TCR sequencing to ask whether CD49b+ activated Treg cells and CD49b− activated Treg cells represent stable states of Treg cell differentiation instructed by distinct TCR repertoires. We did not find a pattern of clonotypes that was specific to either subset, suggesting that essentially all CD49b− Treg cells could give rise to CD49b+ cells. These results shed light on the identity and development of a functionally potent subset of mature effector Treg cells that recirculate through and survey peripheral tissues.

RNA-seq of Treg and Tconv subsets from murine spleen

Project description:While unique subsets of Treg cells have been described in some non-lymphoid tissues, their relationship to Treg cells in secondary lymphoid organs and circulation remains unclear. We have identified a recirculating and highly suppressive effector Treg cell subset that expresses the α2 integrin, CD49b, and exhibits a unique tissue distribution. To identify genes and pathways enriched in CD49b+ Treg cells, we performed RNA-seq of splenic CD49b+ and CD49b− Treg cells that were of otherwise similar activation status based on expression of CD44 and CD62L. This revealed that splenic CD49b+ Treg cells express genes related to migration and activation, but are relatively depleted of genes whose expression is TCR-dependent in Treg cells. These results shed light on the identity and development of a functionally potent subset of mature effector Treg cells that recirculates through and surveys peripheral tissues.

Single-cell RNA-seq of splenic Treg and Tconv cells

Project description:While unique subsets of Treg cells have been described in some non-lymphoid tissues, their relationship to Treg cells in secondary lymphoid organs and circulation remains unclear. We have identified a short-lived effector Treg cell subset that expresses the α2 integrin, CD49b, and exhibits a unique tissue distribution. Projection of the CD49b+ Treg signature onto the Treg phenotypic landscape as inferred by single-cell RNA-seq analysis, placed these cells at the apex of the Treg developmental trajectory. These results shed light on the identity and development of a functionally potent subset of mature effector Treg cells that recirculate through and survey peripheral tissues.

Terminal differentiation and persistence of effector regulatory T cells essential for the prevention of intestinal inflammation [scMultiomics]

Project description:Regulatory T (Treg) cells represent a specialized CD4+ T cell lineage with essential anti-inflammatory functions. Recent studies of the adaptations of Treg cells to non-lymphoid tissues which enable their specialized immunosuppressive and tissue supportive functions raise questions about the underlying mechanisms of these adaptations and whether they represent stable differentiation or reversible activation states. Using novel genetic tools, we characterized the transcriptional programs of distinct colonic effector Treg cell types. We found that attenuated T cell receptor (TCR) signaling and acquisition of substantial TCR independent functionality appears to facilitate the terminal differentiation of a population of colonic effector Treg cells distinguished by stable expression of immunomodulatory cytokine interleukin-10 (IL-10). Functional studies revealed that this subset of effector Treg cells, but not their expression of IL-10, was indispensable for preventing colitis. These findings suggest core features of terminal differentiation of effector Treg cells in non-lymphoid tissues and their function therein.

Resident T Cell Repertoires

Project description:Regulatory T (Treg) are present in lymphoid and non-lymphoid tissues and restrict immune activation, prevent autoimmunity and regulate inflammation. While Treg in non-lymphoid tissues are typically resident, Treg in lymph nodes (LNs) predominantly recirculate and residency of Treg in LNs is poorly studied. Here, we show that 10-20% of all Treg in LNs are memory-like resident cells. Both thymic and peripheral Treg contributed to the pool of resident Treg and their residency did not require continuous TCR signaling. Yet, resident and circulating Treg had distinct TCR repertoires and different LNs contained distinct clonal subpopulations of resident Treg. We speculate that stochastic selection and variation in antigen availability governs commitment of individual T cell clones to the resident pool in each LN. Our results describe a framework for local fine-tuning of immune responses in LNs based on previous adaptive immune responses.

Resident regulatory T cells reflect the immune history of individual lymph nodes

Project description:Regulatory T cells (Treg) are present in lymphoid and non-lymphoid tissues where they restrict immune activation, prevent autoimmunity and regulate inflammation. Treg in non-lymphoid tissues are typically resident, while those in lymph nodes (LNs) are considered to recirculate. However, Treg in LNs are not a homogenous population and circulation kinetics of different Treg subsets are poorly characterized. Furthermore, whether Treg can acquire memory T cell properties and persist for extended periods after their activation in LNs is unclear. Here, we used in situ labeling with a stabilized photoconvertible protein to uncover turnover rates of Treg in LNs in vivo. We found that while the majority of Treg in LNs recirculate, 10-20% are memory-like resident cells that remain in their respective LNs for weeks to months. Single cell RNA sequencing revealed that LN-resident cells are a functionally and ontogenetically heterogeneous population and share the same core residency gene signature with conventional CD4+ and CD8+ T cells. Resident cells in LNs did not actively proliferate and did not require continuous TCR signaling for their residency. Yet, resident and circulating Treg had distinct TCR repertoires, and each LN contained exclusive clonal subpopulations of resident Treg. Our results demonstrate that, similar to conventional T cells, Treg can form resident memory-like populations in LNs after adaptive immune responses. Specific and local suppression of immune responses by resident Treg in draining LNs might provide new therapeutic opportunities for the treatment of local chronic inflammatory conditions.

Rbpj expression in regulatory T cells is critical for restraining TH2 responses [spleen Treg and Tconv RbpjWT expression]

Project description:The transcriptional regulator Rbpj is involved in T-helper (TH) subset polarization, but its function in Treg cells remains unclear. Here we show that Treg-specific Rbpj deletion leads to splenomegaly and lymphadenopathy despite increased numbers of Treg cells with a polyclonal TCR repertoire. A specific defect of Rbpj-deficient Treg cells in controlling TH2 polarization and B cell responses was observed, leading to the spontaneous formation of germinal centers and a TH2-associated immunoglobulin class switch as well as T-cell polarization into TH2 effector cells. The observed phenotype was environment-dependent and could be induced by infection with parasitic nematodes. Rbpj-deficient Treg cells adopted open chromatin landscapes and gene expression profiles reminiscent of tissue-derived TH2-polarized Treg cells, with a prevailing footprint of transcription factor Gata-3. The over-expression of Ilt3 rendered Rbpj-deficient Treg cells incompatible to specifically restrain TH2 responses, finally leading to severe and fatal lymphoproliferative disease.
