They inhibit synthesis of almost all known cytokines and of several cell surface molecules required for immune function , but the mechanism underlying this activity has been unclear. Here it is shown that glucocorticoids are potent inhibitors of nuclear factor kappa B ( NF-kappa B ) activation in mice and cultured cells .
