Abstract
We investigated the influence of recombinant human tumour necrosis factor alpha (TNF-alpha) and its derivatives termed muteins III, V, VI-in which the first 3 to 7 amino acids of native TNF-alpha have been replaced-on the survival time of mice inoculated with leukaemia L1210 or leukaemia P338. TNF-alpha prolonged the survival of mice with leukaemia L1210 but did not have any therapeutic activity in leukaemia P388-bearing mice. Muteins-treated mice with leukaemia P388 lived longer than animals receiving TNF-alpha, while those inoculated with leukaemia L1210 did not show any significant prolongation of life compared with the TNF-alpha treated group. The results presented in this report indicate that the antileukaemic activity of TNF-alpha is governed at least in part by the nature of the N-terminal amino acids.Entities:
