Which of the following statements about induction or maintenance of T cell tolerance is NOT true?
a. Peripheral T cell tolerance to an antigen may be induced by persistent and repeated stimulation of lymphocytes by that antigen in tissues.
b. Peripheral T cell tolerance results when T cells recognize antigen in the setting of an innate immune response to the antigen.
c. Peripheral T cell tolerance to some antigens is induced when mature T cells recognize antigen and bind B7-1 or B7-2 via the inhibitory CTLA-4 receptor.
d. Peripheral T cell tolerance results when mature naive T cells recognize antigens without adequate B7-1â or B7-2âmediated costimulation.
e. Central tolerance is induced when immature developing T cells in bone marrow or thymus encounter self-antigens.
