title: Effects of human recombinant IL-1 on d-tubocurarine-induced histamine release from isolated rat peritoneal mast cells.
abstract: The relationship between d-tubocurarine (d-Tc) and human recombinant interleukin-1 (rIL-1) was studied on the histamine-releasing property of isolated rat peritoneal mast cells. d-Tc induced histamine release in a dose-dependent manner (1 x 10(-4) M-3 x 10(-3) M) from isolated rat mast cells. Human rIL-1 (0.3-10 ng/ml) potentiated the d-Tc-induced histamine release and shifted the dose-response curve to left without changing the maximum histamine release by d-Tc. The potentiation by human rIL-1 was completely blocked by anti-IL-1-antibody. Human rIL-1 neither released histamine nor affected IgE-related histamine release in isolated rat peritoneal mast cells. Human recombinant IL-2, IL-3, and tumour necrosis factor neither released histamine from isolated rat mast cells nor affected d-Tc-induced histamine release. These results suggested that human rIL-1 might hypersensitize d-Tc receptors distributed on plasma membrane of rat mast cells.
