abstract
- Supernatants from endotoxin-stimulated human leukemic cells and human recombinant interferon-beta 2 similarly enhance synthesis of alpha 1-antichymotrypsin and haptoglobin but suppress synthesis of albumin in cultured Hep G2 cells. Human recombinant tumor necrosis factor only slightly affects production of alpha 1-antichymotrypsin and albumin in a similar manner as leukocyte cytokines. In distinction, recombinant human interferon-gamma profoundly inhibits synthesis of alpha 1-antichymotrypsin, and especially of haptoglobin, but stimulates production of alpha 2-macroglobulin thus modulating the acute phase response of these cells.
