To detect a potential defect in immunoregulatory function in atopic subjects, we studied histamine-induced suppressor-T-cell activity and histamine Type 1 and Type 2 receptors on T cells. Peripheral-blood mononuclear cells from 16 atopic subjects generated less histamine-induced suppressor activity than did those from 20 nonatopic normal controls (P<0.005). The percentage of T lymphocytes bearing histamine Type 2 receptors was lower in the atopic group than in the control group (P<0.001), but the percentage of cells with Type 1 receptors was the same in both groups. In the atopic subjects, the functional suppressor-cell abnormality positively correlated with the decreased phenotypic expression of histamine Type 2 receptors. No abnormality in concanavalin A-induced suppressor activity was detected in these subjects. Nonatopic control subjects with systemic mastocytosis had normal functional and phenotypic data, suggesting that chronic activation of atopic T cells in vivo by circulating histamine does not explain the abnormal histamine-induced suppressor response.
