Lymphocyte Cytotoxicity in vitro: Activation and Release of a Cytotoxic Factor

Open access
GRANGER, G. A., WILLIAMS, T. W.·1968·Nature

Abstract

WE have reported that cell contact per se is not sufficient to explain the rapid and dramatic in vitro destruction of target L cells observed when they are treated with immune lymphocytes or non-immune phytohaemagglutinin (PHA)-stimulated lymphocytes derived from various inbred mice1. Instead, cell contact is apparently involved in the induction of additional steps, which result in the release of a soluble toxic factor(s). The presence of the factor(s) is related to the ability of the aggressor cell to promote the destruction of target L cells. Once released, the factor has a non-specific toxic effect when tested on mammalian cells of many genotypes2. Lymphocyte-induced destruction of target cells seems to be related to the capacity of the aggressor lymphocyte to undergo enlargement and form blast cells. With these observations in mind we decided to treat lymphocytes in vitro by various techniques known to induce blast cells, and to test the culture medium for the presence of cytotoxic material.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
