Lysis of human alveolar macrophages by lymphokine-activated killer cells.
In order to determine if human LAK cells were cytotoxic against autologous AM phi, we studied the ability of human peripheral blood MNCs, stimulated in vitro with recombinant human IL-2, to lyse AM phi in a four-hour 51Cr-release assay. These cells showed significant cytotoxicity against autologous AM phi. The AM phi which had been cultured for four days served as better targets than freshly is...
متن کاملLysis of lymphoma cells by autologous and allogeneic natural killer cells.
Studies were undertaken to determine whether natural killer (NK) cells would lyse autologous and allogeneic lymphoma cells. When large granular lymphocytes, which are known to mediate NK activity, were enriched from peripheral blood and used as effector cells, they lysed autologous lymphoma cells of all of eight patients tested, and those of healthy donors lysed lymphoma cells of all of ten pat...
متن کاملLysis of leukemia and lymphoma cells by autologous and allogeneic interferon-activated blood mononuclear cells.
Studies were undertaken to determine whether leukemia and lymphoma cells would be lysed by autologous and allogeneic interferon (IFN) activated peripheral blood mononuclear cells (PBMC). PBMC from healthy donors and from patients were cultured with and without 500 U of highly purified human fibroblast IFN/ml for 24 hr, and then their cytotoxic activity was assayed by a 5-hr 51Cr-release test. O...
متن کاملLymphokine-activated killer cells: lysis of fresh syngeneic natural killer-resistant murine tumor cells by lymphocytes cultured in interleukin 2.
Normal splenocytes that are cultured in the lymphokine, interleukin 2 (IL-2), for as short as 2 days develop lytic activity for fresh syngeneic natural killer-resistant tumor cells as well as natural killer-sensitive YAC cells in a 4-hr 51Cr release assay. Lymphokine-activated killer (LAK) cells do not lyse syngeneic fresh lymphocytes but do lyse syngeneic concanavalin A-induced lymphocyte blas...
متن کاملCannabinoids increase lung cancer cell lysis by lymphokine-activated killer cells via upregulation of ICAM-1.
Cannabinoids have been shown to promote the expression of the intercellular adhesion molecule 1 (ICAM-1) on lung cancer cells as part of their anti-invasive and antimetastatic action. Using lung cancer cell lines (A549, H460) and metastatic cells derived from a lung cancer patient, the present study addressed the impact of cannabinoid-induced ICAM-1 on cancer cell adhesion to lymphokine-activat...
