Abstract:

Phosphodiesterase 7A (PDE7A) has been suggested to be involved in activation of T lymphocytes. In the present study, a possible involvement of PDE7A in function of preactivated T cells (i.e. T lymphoblasts) was investigated using ASB16165, an inhibitor for PDE7A. ASB16165, which has an IC50 value of 15 nM for human PDE7A, suppressed IL-12-induced IFN-gamma production by T lymphoblasts which have been prepared by stimulating mouse T cells with anti-CD3 antibody. In the same experiment, rolipram, a PDE4-specific inhibitor, showed similar effect, while calcineurin antagonist FK506 did not. Forskolin (an adenylyl cyclase activator) and dibutyryl cAMP also inhibited the IL-12-induced IFN-gamma synthesis. Rp-8-Br-cAMPS, an inhibitor of protein kinase A (PKA), reduced the suppressive effect of ASB16165 on the IFN-gamma production by T lymphoblasts. The rescue of IFN-gamma production by Rp-8-Br-cAMPS was also observed in the inhibition by rolipram and forskolin. These findings suggest that PDE7A may regulate function of activated T cells in a cAMP/PKA-dependent manner, and that PDE4 might share the role. The data in our study also indicate that PDE7 inhibitors such as ASB16165 will be beneficial for the patients with immunological disorders.
