Abstract

Spleen cells of normal quails exhibited cytotoxicity on normal embryo cells as well as on virus‐ and chemically transformed cells. Spleen cells responsible for the destruction of target cells were shown to be non‐adherent lymphoid cells which lack surface immunoglobulin and are resistant to the treatment with anti‐thymocyte serum and complement. Spleen cells of quails which were injected with chicken amniotic fluid (ChAmF) showed no cytotoxic activity. Furthermore, the addition of ChAmF‐treated spleen cells abolished the cytotoxic activity of untreated spleen cells. These results indicated the presence of a spleen‐cell population in normal quails compatible with mammalian natural killer (NK) cells and the induction of suppressor cells directed to the NK cells by administration of ChAmF.
