The specific activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and myeloperoxidase, and the specific content of glutathione were not diminished in LK-treated MDM, suggesting that increased synthesis of H(2)O(2) rather than decreased catabolism probably explained the greater release of H(2)O(2) from LK-treated cells.

|
Reactive oxygen metabolites, depletion of tryptophan, and sequestration of iron did not contribute to anti-F. tularensis activity because addition of superoxide dismutase or catalase, excess iron, or tryptophan to IFN-gamma-treated AM did not reverse the anti-F. tularensis activity observed in these cells.

In contrast to cytomegalovirus- and tetanus toxoid-specific T-cell responses, Aspergillus-specific T-cell reconstitution late after allogeneic SCT was characterized by low stimulation indices and a low IFN-gamma/IL-10 ratio.

Interestingly, Trp-P-1-inhibited proliferation in the splenocytes was restored almost completely by N-acetyl-l-cysteine (NAC) and partially by glutathione (GSH), whereas no effect was found when superoxide dismutase and catalase were used.
