Abstract:
:CD30, a member of the TNF receptor family, has been implicated in the activation of T cells and B cells. In the present study, we characterized the expression and function of murine CD30 ligand (mCD153) by utilizing mCD153 transfectants and a novel mAb against mCD153 (RM153), which can inhibit the binding of murine CD30 to mCD153. The mCD153 transfectants did not co-stimulate the proliferation of anti-CD3-stimulated naive T cells but enhanced the proliferation of anti-CD28-co-stimulated T cells. The mCD153 transfectants exhibited a potent co-stimulatory activity for proliferation of pre-activated T cells that expressed CD30 after anti-CD3 and anti-CD28 stimulation. In contrast to the CD30 expression on naive T cells that required anti-CD28 co-stimulation, mCD153 expression was observed on anti-CD3-stimulated T cells without the anti-CD28 co-stimulation, predominantly on CD4(+) T cells with a transient kinetics which peaked at 24 h but disappeared at 48 h. In contrast to the preferential expression of CD30 on Th2 cells, mCD153 was expressed on both Th1 and Th2 cells after anti-CD3 stimulation. These results indicated a differential regulation of CD30 and CD153 expression in T cells, which may be relevant to immuno-regulatory role of the CD30-CD153 interaction.
