CD30 is a member of the tumor necrosis factor receptor (TNFR) superfamily and expressed in both normal and malignant lymphoid cells. However, the role of CD30 in lymphopoiesis is not known. In this study, we showed CD30 was expressed both in T and B cells, but its deficiency in mice had no effect on T- and B-cell development. In fact, CD30 deficiency attenuated B-cell response to T-cell-dependent antigens. The impaired B cell response in CD30-deficient mice is caused by the reduction of activation-induced cytidine deaminase (AID) expression. Moreover, CD30-deficient mice exhibited decreased TCR-mediated T cell proliferation and slightly impaired TCR signaling. High-throughput RNA sequencing analysis revealed that CD30 deficiency led to a decrease of FOXO-autophagy axis in T cells upon TCR stimulation. Thus, CD30 positively regulates T-cell-dependent immune response and T cell proliferation.
