FK-506 inhibits Ca(2+)-dependent transcription of lymphokine genes in T cells, and thereby acts as a powerful immunosuppressant. However, its potential therapeutic applications may be seriously limited by several side effects, including nephrotoxicity and neurotoxicity. At present, it is unclear whether these immunosuppressive and toxic effects result from(More)
In this report we have approached two questions relating to the mechanism of action of cyclosporin A (CsA). First, we address whether the major cytosolic protein for CsA, cyclophilin, is directly involved in mediating the immunosuppressive activity of this drug, and, in particular, whether inhibition of this protein's peptidyl-prolyl cis-trans isomerase(More)
The ability of steroids to modulate the appearance of Interleukin-1(IL-1) in vivo was evaluated in a model of endotoxin shock. High levels of IL-1 were found in serum from A/J mice which were sensitized with P. acnes and challenged with bacterial lipopolysaccharide (LPS). The factor appeared in the serum 2-4 hours after LPS challenge and was dependent on(More)
