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 …

Various cytotoxic functions of blood lymphocytes were studied in 101 patients undergoing
daily treatment with human interferon-α (IFN). Antibody-dependent cellular cytotoxicity and …

Natural cytotoxicity was measured in 51 adult patients with solid epithelial malignant tumors
and in 27 normal subjects. Peripheral blood leukocytes (PBL) from 31% of the patients and …

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

The spontaneous cytolytic activity of human peripheral blood lymphocytes in a short‐term
51chromium release assay was markedly enhanced by pretreatment with partially purified …

Human interferons (IFs) can induce a several-fold increase in the natural cytotoxicity of
human lymphocytes on target cell lines. IFs increase the efficiency of cytotoxicity and the …

Human lymphocytes secrete high levels of interferon a few hours after being cultured with
certain tumorderived or virus-transformed cell lines. Interferon and interferon inducers (eg …

A purified preparation of human leukocyte interferon used at this hospital in the treatment of
malignant diseases was tested for its ability to modify the spontaneous cytotoxicity of …

The influence of daily intramuscular injections of 3× 10 6 units of interferon-α (IFN-α) on the
phagocytic activity of peripheral monocytes was studied in 28 tumor patients. One day after …

The cytotoxic activity of healthy donor lymphocytes toward cells of two human
lymphoblastoid lines was studied by radioimmunoassay with 51Cr. Cells of the following …
