MDNCF neutrophil chemotactic factor

Based on the fact that interleukin-1 (IF-1) induces migration of leukocytes to sites of injection, IF-1 was thought to have chemotactic activity. In fact, leukocyte-derived chemoattractants for phagocytic cells were present in partially purified preparations of IF-1 (Fuger et al, 1983 Sauder et al, 1984). However, when purified to homogeneity, IF-1 lost its chemotactic activity. Further studies revealed that the partially purified IF-1 preparations were contaminated with both a chemotactic factor for monocytes and a monocyte-derived neutrophil chemotactic factor, termed MDNCF (Yoshimura et al, 1987, 1989 Matsushima et al, 1988, 1989). These paradoxical observations were resolved by data showing that IF-1 was a potent inducer of these chemotactic factors. The same mononuclear cell-derived neutrophil attrac-tants were also identified by several other laboratories of (Schroder et al, 1987 Walz et al, 1987). Eater, Farsen et al (1989) reported that MDNCF was chemotactic for T lymphocytes as well as neutrophils, and, based on the presumed involvement of MDNCF in the immune response, it was renamed IF-8 (Farsen et al, 1989 Oppenheim et al, 1991).
