Activation of NK activity and auto-reactive cytotoxicity after hepatectomy
Spleen cells serially sampled from normal mice following partial hepatectomy were tested for antibody-dependent cellular cytotoxicity (ADCC) and natural killer (NK) activity. There was a marked augmentation of these activities of spleen cells from the hepatectomized animals, compared to cells from controls with a simple laparotomy. The augmentation of ADCC in the hepatectomized mice was largely attributable to the activity of T lymphocytes. When cultured with interleukin-2 (IL-2), the spleen cells from hepatectomized mice exhibited cytotoxicity to syngeneic lymphoblasts, which was found to be effected by T cells.
