Lymphokine activated killer cells

Blut, 1989
Various subpopulations of human leukocytes may be induced by lymphokines to exert cytotoxic activity. In man major histocompatibility complex non-restricted tumor cell lysis by interleukin-2 (IL-2) induced peripheral blood lymphocytes is attributed mainly to natural killer cells.

Heterogeneity of the lymphokine-activated killer cell phenotype

Cellular Immunology, 1991
Lymphokine-activated killer cells (LAK) are functionally defined by their ability to mediate the MHC-unrestricted lysis of a range of tumor targets, while sparing normal cells. They can also lyse TNP-modified normal syngeneic lymphoblasts. We show here that lysis of TNP-modified targets is mediated by CD8+ LAK in a self-MHC-restricted manner, whereas ...

Effect of ouabain on lymphokine-activated killer cells

International Journal of Immunopharmacology, 1994
A large amount of evidence points towards the potential role of lymphokine activated killer (LAK) cells as tools in the treatment of chronically stressed conditions, such as cancer. The modulation of this activity by biologically active endogenous compounds of the HPA (hypothalamic-pituitary-adrenal) axis, however, is not completely understood. Ouabain,

Lymphokine-activated killer cells in rats: Generation of natural killer cells and lymphokine-activated killer cells from bone marrow progenitor cells

Cellular Immunology, 1989
The coculture of rat bone marrow cells with recombinant interleukin-2 induced the generation of cells mediating natural killer (NK) activity and subsequent lymphokine-activated killer (LAK) activity depending upon the dose of IL-2 and time of culture. NK activity was detected as early as 4 to 5 days after the addition of IL-2 and could be evoked with ...

Modulation of natural killer and lymphokine-activated killer cell cytotoxicity by lactoferrin [PDF]

open access: possibleJournal of Leukocyte Biology, 1992
Abstract Natural killer (NK) and lymphokine-activated killer (LAK) cell cytotoxic functions can be strongly augmented by the iron-carrier protein lactoferrin (LF). LF significantly enhances NK and LAK activities when added at the beginning of NK or LAK cytotoxicity assays.

Lymphokine-Activated Killer Cell Activity in Lung Cancer

Chest, 1991
This study evaluates local pulmonary immune effector cell lytic activity. Purified lymphocyte populations were isolated from BALF obtained from 18 patients with bronchogenic carcinoma, six patients with lung disorders other than cancer, and ten normal control volunteers matched for age and smoking history. These cells were evaluated for NK and LAK cell

Apheresis techniques in lymphokine‐activated killer cell production

Journal of Clinical Apheresis, 1988
AbstractAdoptive transfer of autologous lymphokine‐activated killer cells (LAK) in conjunction with recombinant interleu‐kin‐2 (rIL‐2) has been reported to produce significant regression in metastatic disease in patients with advanced cancer. In an effort to confirm the results reported by the Surgery Branch of the National Cancer Institute, the same ...

Lysis of endothelial cells by autologous lymphokine-activated killer cells

Cancer Immunology Immunotherapy, 1994
The mechanisms of lysis of endothelial cells derived from human umbilical vein (HUVEC) by autologous lymphokine-activated killer (LAK) cells, generated from cord blood lymphocytes of the same donor, were investigated. Freshly isolated HUVEC as well as HUVEC cultured for several passages were efficiently lysed by autologous LAK cells, and their ...
