Research Abstract |
To elucidate the mechanism of immune tolerance in the periphery, we analyzed the role of calcium signaling in regulatory T cells and dendritic cells using cell-type specific Stim-deficient mice. In the absence of store-operated calcium entry in T cells, regulatory T cell development in the thymus was blocked at the transition of precursor cells to mature regulatory T cells. As a result, peripheral immune tolerance was disrupted. Block of calcium signaling in dendritic cells resulted in mild impairment of immune response to antigen but not of peripheral immune tolerance.
