Expression of EBF is critical for the lineage specification at the early stage of B cell develop-ment. IL-7 and IL-7R are participants in the formation of the transcription factor network during B lymphopoiesis by maintaining the EBF expression level above a certain threshold. These are necessary for further transition of B cell progenitors. Elevated GC in exercise induces rapidly apoptosis in developing B lymphocytes. It is important and practical for athletes,immune modification to study the lymphocyte development and its regulation. |
