Natural killer cells may play a significant role in virus infections. Virus-induced interferon
activates these cells to become highly cytotoxic, and viral infections may also affect the …

Purified hemagglutinin and fusion glycoproteins of measles virus either in soluble form or
inserted in artifical membranes bind to human peripheral blood lymphocytes and induce cell …

The cytotoxic activity of effector cells from mice infected with Toxoplasma gondii was tested
in a 4-to 5-hr 51Cr release assay, using RL 1 and YAC-1 target cells. They showed …

The role of the glycoproteins of influenza virus, hemagglutinin (HA), and neuraminidase
(NA) in the in vitro stimulation of natural cell-mediated cytotoxicity (NCMC) or natural killer …

The levels of natural cell-mediated cytotoxicity could be augmented by administration of
Aloctin A (Alo A), a lectin having anti-tumor activity. iv administration of Alo A induced …

Natural killer (NK) cells have cytotoxic activity in vitro against a variety of tumor cells, against
some microorganisms, and against cells which are infected with microbial agents. In …

Natural cell‐mediated cytotoxicity (NCMC), measured against a variety of tumors, is
mediated by at least two sub‐populations of effector cells: natural cytotoxic (NC) and natural …

" Natural killer cells" were discovered some ten years ago in the course of studies on cell-
mediated cytotoxicity (CMCT). A considerable part of" natural reactivity" was found to be …
