Regulation of liver regeneration by interleukin-2 and its inhibitors: Cyclosporine A and FK 506
Abstract
Several investigations have been suggesting that lymphocytes can be responsible for growth regulation of liver. The interleukin-2 (IL-2) production by spleen cells was noted to be increased 2 days after resection of 70% of the volume of the liver in C3H/He mice. The effects of IL-2 production and its antagonists: cyclosporine A (CsA) and FK506 on liver regeneration were thus studied by measuring in vivo incorporation of Bromodeoxyuridine (BrdU). By intraperitoneal injection of IL-2 5 times every 8 h after hepatectomy. BrdU labeling indices at 36 h after the operation were suppressed in a dose-dependent manner. On the other hand, treatment with CsA and FK506, which inhibit IL-2 production, increased the mitotic indices of the regenerating livers. Serum levels of aminotransferases were not affected by FK506 at a dose sufficient for the mitotic stimulation. Based on these results, CsA and FK506 would appear to stimulate liver cell proliferation by suppressing IL-2 production and inhibiting of NK cell activity.

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.
