Enriched lymphocytes from patients with primary hepatocellular carcinoma showed
considerably reduced natural cytotoxicity against two established hepatoma cell lines and …

Lymphokine-activated killer activity and natural killer activity in hepatocellular carcinoma
patients were assessed. Maximum lymphokine-activated killer activity was induced at 3 to 5 …

We have measured natural killer (NK) cell activity in patients with hepatocellular carcinoma
(HCC) and have examined the effects of in vitro and in vivo administration of a-interferon …

Most previous studies of lymphocyte-mediated cytotoxicity to animal and human hepatocytes
have not taken into account the ability to human lymphoid cells to kill spontaneously cultured …

Natural killer (NK) and activated killer (AK) cells appear to be important in
immunoregulation, elimination of virus-infected cells and resistance to tumours. NK activity …

Natural killer (NK) cells may play an important role in immune surveillance against tumours
(Herberman, 1982) and interferons (IFN) may serve as modulators of their cytolytic activity …

The natural killer (NK) activity of peripheral blood mononuclear cells from 25 patients with
squamous cell carcinoma of the lung, malignant melanoma, or epitheloid cancers of the …

Lymphokine activated killer cell is a newly described lytic system against a variety of solid
tumours and is distinct in several respects from the classic cytolytic T cell and the natural …

Abstract A substantial proportion (44%) of peripheral blood lymphocyte samples from 41
patients with malignant lymphoma have been shown to have depressed or undetectable …

Natural killer cell activity, which represents the spontaneous cytotoxicity of lymphocytes
toward tumor cells, has been measured in 173 tumor-bearing patients and 25 healthy …
