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 …

Using the natural killer (NK) sensitive K562 cell line, enhanced NK cell cytotoxicity was
demonstrable early in the course of acute hepatitis B while normal values were obtained in …

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

The natural killer (NK) cell activity of peripheral blood lymphocytes (PBL) in patients with
various chronic liver diseases, and its in vitro response to human interferon‐α (Le) were …

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 …

Liver-derived lymphocytes were isolated from 40 human livers with end-stage liver disease
that were removed at the time of orthotopic liver transplantation. In addition, 10 resection …

Blood· borne cells with the characteristics described for the natural killer (NK) lymphocytes
were recovered from the liver sinusoids in rat. They had cytotoxic activity against K 562 cells …

We investigated the distribution of liver NK cells in mice of various ages and their cytotoxicity
against regenerating hepatocytes. Liver NK cells were identified by asialo GM1 antibody in …

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 …
