Natural killer (NK) activity and antibody-dependent cellular cytotoxicity (ADCC) of peripheral blood lymphocytes from untreated non-Hodgkin's lymphoma patients were found to be depressed, when tested against the human erythroblastoid cell-line K562. The percentage of active killer (AK) cells and that of target binding cells (TBC) of the patients were also inhibited. Treatment of the patients lymphocytes with interferon (IFN) caused an augmentation in their NK activity which was comparable with that seen in the controls. Lymphocytes from some of the patients and controls were cocultured with K562 cells for production of natural killer cytotoxic factors (NKCF). The NKCF released by the patients lymphocytes showed a reduced lytic activity against K562 target cells. The depression in all the activities reported here showed a correlation with the clinical status of the patients except in the case of ADCC. These results indicate that further characterization of the properties of NKCF will contribute the understanding of the mechanism of NK cytotoxicity.

UI	MeSH Term	Description	Entries
D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007113	Immunity, Innate	The capacity of a normal organism to remain unaffected by microorganisms and their toxins. It results from the presence of naturally occurring ANTI-INFECTIVE AGENTS, constitutional factors such as BODY TEMPERATURE and immediate acting immune cells such as NATURAL KILLER CELLS.

D007370	Interferon Type I	Interferon secreted by leukocytes, fibroblasts, or lymphoblasts in response to viruses or interferon inducers other than mitogens, antigens, or allo-antigens. They include alpha- and beta-interferons (INTERFERON-ALPHA and INTERFERON-BETA).	Interferons Type I,Type I Interferon,Type I Interferons,Interferon, Type I,Interferons, Type I
D007694	Killer Cells, Natural	Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D008228	Lymphoma, Non-Hodgkin	Any of a group of malignant tumors of lymphoid tissue that differ from HODGKIN DISEASE, being more heterogeneous with respect to malignant cell lineage, clinical course, prognosis, and therapy. The only common feature among these tumors is the absence of giant REED-STERNBERG CELLS, a characteristic of Hodgkin's disease.

D003602	Cytotoxicity, Immunologic	The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.

D000920	Antibody-Dependent Cell Cytotoxicity	The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent.
