A regulatory role for TCF7 is proposed in limiting access to the Treg lineage by influencing the required TCR signaling strength of Treg precursors and broadening the repertoire and allowed lower TCR affinities to be recruited into the T Reg lineage.

Figures from this paper

TCF-1 controls Treg functions that regulate inflammation, CD8 T-cell cytotoxicity, and severity of colon cancer.

Treg cell–specific TCF-1 expression differentially regulates TH17-mediated inflammation and T cell cytotoxicity, and can determine colorectal cancer outcome, as well as cooperates with FOXP3 to differentially regulate independent suppressive activities of Treg cells.

TCF1 in T cell immunity: a broadened frontier

Key findings are summarized across the fields of T cell immunity and the possibility of exploring TCF1 and its downstream transcriptional programmes as therapeutic targets for improving antiviral and antitumour immunity is reflected.

Tcf1 and Lef1 are required for the immunosuppressive function of regulatory T cells

The data collectively indicate that Tcf1 and Lef1 are critical for sustaining T reg suppressive functions and preventing loss of self-tolerance.

Proteomic Analysis of Regulatory T Cells Reveals the Importance of Themis1 in the Control of Their Suppressive Function*

This study highlights the usefulness of label free quantitative methods to better characterize the Treg cell lineage and demonstrates the potential role of Themis1 in the suppressive functions of these cells.

An essential role for miR-15/16 in Treg suppression and restriction of proliferation

It is demonstrated that miR-15/16 expression in Tregs is essential to maintain immune tolerance and restrict Treg proliferation and regulate expression of the key functional Treg molecules FOXP3, IL2Rα, CTLA4, PD-1 and IL7Rα.

T cell factor-1 regulates CD4+ and CD8+ T cell responses in a stage-specific manner

The studies revealed that loss of TCF1 long isoforms did not impact the expansion or differentiation of cytotoxic effector T cells, andTCF1 short isoforms remained critical for memory CD8 T cell maturation to TCM cells.

The Role of WNT Signaling in Mature T Cells: T Cell Factor Is Coming Home

The molecular mechanisms underlying T cell factor's functional role in mature T cells have been discussed and the implications and limitations for WNT manipulation as a therapeutic approach for treating immune-related diseases are explored.

First Insight into the Kinome of Human Regulatory T Cells

Treg-specific expression pattern of 11 protein kinases substantiate the current opinion that TCR-mediated signaling cascades are altered in Tregs and further suggests that T Regs exhibit significant specificities in cell-cycle control and progression.

Premature Expression of Foxp3 in Double-Negative Thymocytes

The results indicate that Tcf7 is involved in preventing the premature expression of Foxp3 in DN thymocytes, and suggest that thymic selection process of these T cells depends on TCR signaling to maintain self-tolerance and counterbalance overshooting immune responses.

Genomic definition of multiple ex vivo regulatory T cell subphenotypes

Treg cells from the gut proved dissimilar to cells elicited by exposure to TGFβ in vitro, but instead they resembled a CD103+Klrg1+ subphenotype preferentially generated in response to lymphopenia.

Foxp3-dependent programme of regulatory T-cell differentiation

Although its function is required for Tr cell suppressor activity, Foxp3 to a large extent amplifies and fixes pre-established molecular features of Tr cells, including anergy and dependence on paracrine IL-2.

A critical role for TCF-1 in T-lineage specification and differentiation

TCF-1 is highly expressed in the earliest thymic progenitors, and its expression is upregulated by Notch signals, which drives the development of T-lineage cells in the absence ofT-inductive Notch1 signals.

T cell receptor signal strength in Treg and iNKT cell development demonstrated by a novel fluorescent reporter mouse

Generation of a Nur77 reporter mouse is used to demonstrate TCR signal strength during thymic selection and peripheral maintenance of conventional and nonconventional T cell subsets and presents a
