A role for T cells in immune surveillance has long been suggested1, but the lack of high
tumour incidence in T cell-deficient nude mice represented a challenge to this hypothesis …

Natural killer (NK) activity of human peripheral blood lymphocytes (HPBL) was studied in 32
alcoholics and 15 control subjects in a 4‐h chromium release assay using K562 tumor target …

Abstract Concanavalin A (Con A)-induced cytotoxic activity, interferon (IFN) and interleukin-2
(IL-2) levels in cultures of spleen cells from young (2-3 months) and old (22-24 months) …

Generation of natural killer (NK) activity in response to a partially purified preparation of rat
interleukin-2 (IL-2) was compared in spleen cells derived from young (8-10 weeks old) and …

Six-week-old C57B1/6 female mice were fed a normal (24% protein) or an isocaloric but
protein-deficient (4% protein) diet. At different time periods after the initiation of diets, basal …

Natural killer (NK) cells have recently gained much attention as potential effector cells in
antitumor and antiviral immune defense mechanisms. The role of NK cells in patients with …

Antibodies reactive with effector cells were shown to augment the cytotoxicity of spleen cells
from athymic nude and euthymic mice. The addition of alloantibody to the assay or …

Comparisons were made between the characteristics of cytotoxicity activation in mouse
spleen cells, induced by specific anti-H-2 antiserum, interferon (IF), interferon inducer (poly …

Abstract The Fc receptor for IgG on human natural killer (NK) cells can be identified by a
series of murine monoclonal antibodies. When these antibodies with IgG 1 isotype (eg, Leu …

The increased use of nanomaterials for biomedical purposes has warranted the need to
introspect their toxicological properties and assess their utility to human health, particularly …
