Title Inhibition by dexamethasone of interleukin 13 production via glucocorticoid receptor-mediated inhibition of c-Jun phosphorylation.
Journal FEBS Lett.
Abstract The antigen stimulation of RBL-2H3 cells induced interleukin 13 (IL-13) production, which was inhibited by the steroidal anti-inflammatory drug dexamethasone and by the c-Jun N-terminal kinase (JNK) inhibitor SP600125. Dexamethasone did not inhibit the antigen-induced phosphorylation of JNK but inhibited that of c-Jun. In a cell-free system, the phosphorylation of glutathione S-transferase-fused c-Jun by recombinant JNK was not inhibited by dexamethasone but was inhibited by the addition of recombinant glucocorticoid receptor (GR). These findings suggest that the inhibition of antigen-induced IL-13 production by dexamethasone is due to the GR-mediated inhibition of c-Jun phosphorylation induced by JNK.
