Antigen receptor signaling competence and the determination of B cell fate in B-lymphopoiesis

, : Antigen receptor signaling competence and the determination of B cell fate in B-lymphopoiesis. Histology and Histopathology 20(1): 187-196

Recent studies suggest that developmental check-points in B-lymphopoiesis are set in order to test the B cell receptor signaling competence. In these check-points ligand-independent and ligand-dependent receptor signals confer B-lymphopoiesis with positive and negative selection events. As a consequence, B-lymphocytes are forced to make crucial fate decisions to determine developmental progression, survival or apoptosis. In here we review recent progress in unraveling molecular and cellular mechanisms for the role of B cell receptor signaling competence in determination of the B cell fate.
