TCRalphabeta repertoire diversity of human naturally occurring CD4+CD25+ regulatory T cells.

abstract：:The thymus contains a low frequency of B cells, about 0.1-0.5% of total population of thymocytes that were shown to contribute in thymic negative selection. The fact that B cells in the periphery have been contributed in the generation of the T regulatory cell compartment emerged the idea that this process may indeed ...
