Desensitization in normal rat peritoneal mast cells was induced by subthreshold and suboptimal levels of antirat IgE under normal calcium buffer conditions. Low doses of anti-IgE which triggered 0-10% net histamine release, initiated up to 100% desensitization. The rate of desensitization was highly variable in different rats, resulting in an irregular decay of releasability over the first 30 min. After 120-150 min of desensitization, rat mast cells in 3 of 5 experiments spontaneously regained… CONTINUE READING
