Abstract excerpt
Glucocorticoids (GCs) induce apoptosis in lymphoid cells through activation of the GC receptor (GR). We have evaluated the role of p38, a MAPK, in lymphoid cell apoptosis upon treatment with the synthetic GCs dexamethasone (Dex) or deacylcortivazol (DAC). The highly conserved phosphoprotein p38 MAPK is activated by specific phosphorylation of its threonine180 and tyrosine182 residues. We show that Dex and DAC...
