Cachectin/tumor necrosis factor: production, distribution, and metabolic fate in vivo.

Beutler, B A, Milsark, I W, Cerami, A·1985·The Journal of Immunology

Abstract

A highly specific radioreceptor assay for cachectin/tumor necrosis factor (TNF) was utilized to measure the time course of lipopolysaccharide (LPS)-induced hormone production in rabbits. Cachectin/TNF bioactivity was monitored in the same serum samples by measuring lipoprotein lipase (LPL) suppression in 3T3-L1 cells. Cachectin/TNF is produced in large quantities by LPS-treated rabbits without priming by bacillus Calmette Guérin, C. parvum, or other agents. Nanomolar concentrations of the hormone are achieved, with peak levels occurring at 2 hr postinjection; the hormone is rapidly cleared thereafter. In separate studies, mice were used to assess the distribution and metabolic fate of cachectin/TNF. Radioiodinated hormone is cleared from the plasma with a half-life of 6 to 7 min. Studies of the tissue distribution of label after injection demonstrate that liver, kidneys, skin, and gastrointestinal tract take up most of the hormone. Electrophoretic analysis of tissues recovered from injected animals suggests that the hormone is very rapidly degraded after binding.

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.
