Beta-catenin stabilization extends regulatory T cell survival and induces anergy in nonregulatory T cells

If a stable form of the important WNT pathway molecule β-catenin is expressed on CD4+CD25+ T regulatory (Treg) cells, cell survival is markedly increased in vitro. This was reported by a lab group from the New York University School of Medicine (USA).
Stable β-catenin-expressing CD4+CD25+ Treg cells were also observed to outcompete control Treg cells in vivo while the number of Treg cells necessary for protection against inflammatory bowel disease was significantly lower when stable β-catenin-expressing CD4+CD25+ Treg cells were used instead of control Treg cells. Under circumstances with stable β-catenin expression in potentially pathogenic CD4+CD25- T-cells, the cells were inactive. This β-catenin-dependent inactivity could even be seen in Foxp3-deficient T-cells. Stabilisation of β-catenin therefore seems to have a strong effect on prevention of inflammatory disease by increasing survival of already existing regulatory T-cells and through the the unresponsiveness of T effector cell precursors.
