Regulation of alphabeta/gammadelta T cell lineage commitment and peripheral T cell responses by Notch/RBP-J signaling.

RBP-J is a key mediator of Notch signaling that regulates a large spectrum of cell fate determinations. To elucidate the functions of Notch signaling in T cell development, we inactivated RBP-J specifically at two stages of T cell development by crossing RBP-J floxed mice with lck-cre or CD4-cre transgenic mice. The loss of RBP-J at an earlier developmental stage resulted in enhanced generation and accelerated emigration of gammadelta T cells, whereas alphabeta T cell development was arrested at the double-negative 3 stage. The loss of RBP-J at a later stage did not affect the absolute number or the production rate of CD4 or CD8-positive mature T cells but enhanced Th1 cell response and reduced CD4(+) T cell proliferation. Our data demonstrated that Notch/RBP-J signaling regulates gammadelta T cell generation and migration, alphabeta T cell maturation, terminal differentiation of CD4(+) T cells into Th1/Th2 cells, and activation of T cells.[1]
