Selective natural killer resistance in a clone of YAC lymphoma cells.

YAC lymphoma cells were treated with the mutagen N-methyl-N'-nitro-N-nitrosoguanidine and then cloned and subcloned. Of 51 clones, 3 were selected for further study. Ten-fold more natural killer (NK) effector cells were required to lyse YAC clone 6 and subclone 6-28 cells compared with clone 19 cells or the YAC parent cell line. The maximum plateau level of cytolysis of the NK-resistant (NKR) v...

Leukemia and Lymphoma of Natural Killer Cells

Malignant hematolymphoid disorders arising from NK cells have become widely recognized over the past decade. The two forms of NK-cell malignancy, aggressive NK-cell leukemia (ANKL) and extranodal NK-cell lymphoma of nasal type (ENKL) are both characterized by the proliferation of tumor cells with an NK-cell like immunophenotype. ANKL usually presents with bone marrow tumor cells accompanied by ...

Increased Natural Killer Cells Activity in Schizophrenic Patients

Background: Schizophrenia has been associated with altered immunity. Different studies regarding natural killer cell activity (NKA) in schizophrenic patients have shown inconsistent results. Objectives: To evaluate NK cell activity in schizophrenic patients in comparison with healthy control individuals.   Methods: 30 medication-free schizophrenic patients and 41 healthy sex, age and smoking st...

Toxoplasma-induced activities of peritoneal and spleen natural killer cells from beige mice against thymocytes and YAC-1 lymphoma targets.

Homozygous (bg/bg) and heterozygous (bg/+) beige mice were infected with Toxoplasma gondii, and splenic and peritoneal natural killer (NK) cell activities were assayed against YAC-1 lymphoma (NK-YAC) and thymocyte (NK-THY) targets. Although uninfected bg/bg mice were devoid of NK-YAC activity when compared with bg/+ mice, NK-THY activity was at a completely normal level. Both effector cells sho...

The Effects of Dienogest on Macrophage and Natural Killer Cells in Adenomyosis: A Randomized Controlled Study

Objective Inflammation plays an important role in endometriosis and adenomyosis. Progestin has been used for symptomatic treatment of adenomyosis, although its effect on inflammation has not been studied. We conducted a randomized controlled study to investigate the changes of immune cell expression, i.e. macrophages and natural killer cells, in the tissue obtained from women with adenomyosis w...
