Oy. Chertov et al., INHIBITORY EFFECT OF CALF FETUIN ON THE CYTOTOXIC ACTIVITY OF LAK CELL-DERIVED FACTORS AND TUMOR-NECROSIS-FACTOR, Immunology letters, 42(1-2), 1994, pp. 97-100
A protein-inhibiting LAK cell-mediated cytotoxicity was isolated from
a LAK cell-conditioned medium. The N-terminal amino acid sequence of t
his protein appeared to be identical to fetal calf fetuin. Pure isolat
ed fetuin, as well as commercially available preparations of this prot
ein, were shown to inhibit cytotoxic activity of both cytotoxic protei
ns released by LAK cells and TNF.
