## Abstract The activity of systemic and __in situ__ natural killer (NK) cells was measured in 3β to 5βweekβold CBA mice with progressively growing murine sarcoma virus (MSV)βinduced tumors. Splenic NK activity was depressed in tumorβbearing mice. NK activity was quite low or not detectable in unfr
The natural-killer(NK)-cell-mediated cytotoxicity to syngeneic tumor cells can be augmented by in vivo priming and subsequent in vitro challenge with the streptococcal preparation OK432. Supernatants of cocultures of spleen cells with OK432 contained interleukin-2 (IL-2) and interferon (IFN), mainly
