Various cell depletion techniques were employed to identify the cells responsible for the
natural killer (NK) activity against YAC‐1 targets that is present in lymphoid tissues of SJL/J …

Lymphoid cells taken from the grossly enlarged lymph nodes (LN) and spleens of SJL/J
mice bearing transplantable reticulum‐cell sarcomas (RCS), showed increased levels of …

Two transplantable reticulum cell sarcomas (RCS) of SJL mice expressed marked levels of
natural killer (NK) activity when tested against susceptible 51 Cr-labeled tumor targets. In …

A marked increase in natural killer (NK) activity is observed with lymphoid cells prepared
from SJL/J mouse spleen and lymph nodes, in which a transplantable reticulum‐cell …

The activity of systemic and in situ natural killer (NK) cells was measured in 3‐to 5‐week‐old
CBA mice with progressively growing murine sarcoma virus (MSV)‐induced tumors. Splenic …

The role of natural killer (NK) cells in controlling tumor growth was investigated using an NK‐
susceptible (cl27v‐IC2) and an NK‐insusceptible (c127av) subline of the lymphoma …

Effector cells mediating natural killer (NK) cell activity and antibody‐dependent cellular
cytotoxicity (ADCC) have been receiving considerable interest recently as they may …

Intravenous injection of rabbit anti‐asialo‐GM1 serum, an antiserum previously shown to
eliminate splenic natural killer (NK) activity in vitro, profoundly depressed NK activity in CBA …

We have previously found that natural killer (NK) activity is profoundly decreased in BALB/c
mice bearing large mammary tumors. Kinetic studies showed that after 14 days of tumor …

Our earlier studies revealed an increase in the level of null (surface IgM-negative, Thy 1-
negative) lymphocytes in mice shortly after tumor transplantation and before the clinical …
