Natural killer cell activity against a variety of target cell lines in normal persons: NK-target sensitivity and effect of age and sex on NK levels.
Natural killer (NK) cells have been implicated as first line of defence mechanism for carcinogenesis in humans. A lot of studies of depressed NK activity in patients with malignancies have supported this. Two major problems, however, in these studies are the choice of normal controls and target cells. To study this problem, peripheral mononuclear cells (PBMC) of sixty-six normal subjects from y...
متن کاملPediatric Natural Killer Cell Malignancy
Natural killer (NK) cell malignancy is a heterogeneous disorder and rare, representing <1% of non-Hodgkin lymphomas for most of the world, except in Asia and Latin America. In Asia, especially, the incidence of NK-cell lymphomas is approximately 7%–10% of lymphomas [Au et al., 2005]. The pathogenesis of NK-cell malignancies has not yet been fully elucidated. In the 2008 World Health Organizatio...
متن کاملHyperthermia Increases Natural Killer Cell Cytotoxicity against SW-872 Liposarcoma Cell Line
Background: Although there is convincing data in support of the effectiveness of hyperthermia in tumor therapy, the molecular mechanisms underlying the clinical effects of hyperthermia are still poorly understood. Objective: To investigate natural killer (NK) cell cytotoxicity against heat-treated SW-872 and HeLa tumor cell lines. Methods: NKG2D ligands and HLA class I transcription were examin...
متن کاملRat natural killer cell activity against lymphoid and nonlymphoid tumor cells and normal rat cell lines.
Natural cytotoxicity in the rat was assessed against solid tumors and normal and embryonic rat monolayer culture lines, and the results were compared with rat natural killer activity towards syngeneic, allogeneic, and xenogeneic lymphoma targets. The targets tested showed a very wide range of susceptibility to lysis by peripheral blood and spleen effector cells in both 4- and 18-hr cytotoxicity...
