(1989) Israel i Med. Sci. 25:332-338; Bone, R.C. and Brown, R.C. (1990) in Vincent, J.L. (ed.) "Update in Intensive Care and Emergency Medicine 10", Heidelberg: Springer Verlag, p. 121).

  • 11-18 is a recently cloned cytokine that shares the property of IFN ⁇ induction with EL-12, but is structurally related to the IL-1 family of proteins (Bazan et al. (1996) Nature 379:591).
  • IL-18 is synthesized as a biologically inactive precursor molecule (proIL-18) which requires proteolytic cleavage for activation. It has been shown that LPS-induced IFN ⁇ production was dependent upon caspase-1 -mediated activation to proIL-18 both in vivo and in vitro. Caspase-01-/- mice fail to generate IFN ⁇ in response to LPS and specific caspase-1 inhibitors completely abrogate LPS-induced IFN ⁇ production by human PBMCs.
  • Caspases are unique intracellular cysteine proteases that require an aspartic acid residue at the PI position, and appear to play a central role in inflammatory and apoptotic processes. Fourteen of these enzymes have been identified to date.
  • Caspase-1 is a prototype of an inflammatory caspase that activates the pro- inflammatory cytokines, IL-lb and IL-18, in response to LPS.

  • both IL-12 and IL-18 may be necessary for ec-DNA-induced IFN ⁇ production, but unlike after LPS stimulation, a caspase(s) other than caspase-1, is required for ec-DNA-induced IL-18 and IFN ⁇ production.
  • caspases The role of caspases in IFN ⁇ production from T cells was also studied. Caspase- 1-/- mice immunized with KLH were found to generate normal levels of IFN ⁇ following stimulation of draining lymph node lymphocytes with KLH ex vivo ( Figure 10a). To determine the IL-18-dependence of KLH-induced IFN ⁇ production, the effects of anti- IL- 18 antiserum or anti-IL-12 antibodies on this response were studied. Separately, anti- IL- 18 or anti-IL-12 antibodies inhibited KLH-induced IFN ⁇ production only partially (- 50%) showing that each of these cytokines was important for optimal IFN ⁇ production after T cell activation.

Abstract

Cette invention se rapporte à un procédé visant à moduler la sensibilité aux corticostéroïdes chez un sujet. Conformément à ce procédé, on administre audit sujet un agent qui s'oppose à une cible qui régule la production de IFN-η, ainsi qu'un corticostéroïde de sorte que la sensibilité du sujet au corticostéroïde est modulée en comparaison de ce qu'elle est lorsque le corticostéroïde est administré seul. Selon un mode de réalisation, ledit agent est un antagoniste de IL-18. Selon une autre mode de réalisation, ledit agent est un antagoniste de l'interleukine-12 (IL-12). Selon encore un autre mode de réalisation, l'agent est un antagoniste des cellules NK. Selon un mode de réalisation préféré, l'agent est un inhibiteur d'une protéase de la famille des caspases, de préférence un inhibiteur de l'enzyme de conversion de l'interleukine-1 (ICE). Dans un autres mode de réalisation préféré, l'agent est un anticorps monoclonal anti-IL-12 ou un anticorps anti-asialo-GM1 ou un anticorps NK1.1. D'autres agents préférés incluent les inhibiteurs de phosphodiestérase IV et des agonistes béta-2. Les procédés de cette invention s'avèrent utiles au traitement d'une pluralité de maladies et troubles inflammatoires et immunologiques. Cette invention se rapporte également à des compositions pharmaceutiques comportant un agent qui s'oppose à une cible qui régule la production d'IFN-η; chez un sujet, à un corticostéroïde et à un excipient pharmaceutiquement acceptable. Une composition préférée comprend un inhibiteur de ICE, un corticostéroïde et un excipient pharmaceutiquement acceptable.
