We have examined the effects of protein kinase C (PK-C) stimulation and cytosolic Ca2+ elevation on the in vitro induction of non-histocompatibility-restricted tumoricidal activity from human peripheral blood lymphocytes. The tumor cytolytic activity, as well as the number of cells recovered from interleukin 2 (IL-2)-stimulated cultures, was enhanced by the addition of the PK-C stimulator, phor...
The feasibility of in vitro interleukin 2 (IL-2) activation and expansion of mononuclear cells (MNCs) derived from adult patients with acute myelogenous leukemia (ANLL) was studied. Patients' natural killer (NK) and lymphokine-activated killer (LAK) cell activity was compared with that of normal donors in terms of: (a) cytolytic activity (four-hour 51Cr release assay) against an NK-sensitive ta...
A large number of CD4+ T cell clones, obtained from peripheral blood T lymphocytes by direct limiting dilution, allowed us to address the question whether functional heterogeneity exists within the human CD4+ T cell subset. Cytotoxic capacity of cloned T cells was analyzed with the use of anti-CD3 antibodies and target cells bearing FcR for murine IgG. 6 of 12 CD4+ clones obtained were able to ...
We have examined the effects of protein kinase C (PK-C) stimulation and cytosolic Ca* elevation on the in vitro induction of non-histocompatibility-restricted tumoricidal activity from human peripheral blood lymphocytes. The tumor cytolytic activity, as well as the number of cells recovered from interleukin 2 (IL-2)-stimulated cultures, was enhanced by the addition of the PK-C stimulator, phorb...
