Destruction of Rat Islet Cell Monolayers by Cytokines: Synergistic Interactions of Interferon-γ, Tumor Necrosis Factor, Lymphotoxin, and Interleukin 1

Pukel, Clifford, Baquerizo, Hernan, Rabinovitch, Alexander·1988·Diabetes

Abstract

An assay was developed to detect the cytotoxic effects of cytokines on rat pancreatic islet cells in monolayer culture. Cell lysis was detected by a 51Cr-release assay after 4 days of incubation with various cytokines. When tested alone, murine (rat and mouse) interferon-γ (mIFN-γ) produced a small dose-dependent lysis of islet cells; human IFN-γ, mouse IFN-α/β, interleukins 1 and 2 (IL-1 and IL-2), tumor necrosis factor (TNF), and lymphotoxin (LT) were inactive. When added together, the following combinations of cytokines showed synergistic cytotoxic effects: TNF (or LT) plus IL-1, TNF (or LT) plus mIFN-γ, and IL-1 plus mIFN-γ. These results indicate that the cytokine products of mononuclear cells of the immune system, IFN-γ, TNF, LT, and IL-1 have strong synergistic cytotoxic effects on islet cells and therefore may act as direct chemical mediators of islet β-cell destruction in type I (insulin-dependent) diabetes.

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.
