Integrated T-cell receptor and costimulatory signals determine TGF-β-dependent differentiation and maintenance of Foxp3+ regulatory T cells.

abstract：:Alpha4-mediated signaling is involved in a variety of functions in mammalian cells. To determine whether this is true for immunocompetent cells, we generated mutant (Lck-alpha4-) mice in which the alpha4 gene was deleted in a T cell-specific manner using the Cre/loxP system. These mice showed impaired early T cell dev...
