title: Suppression of skin reactivity in rats bearing IgE or IgG2a immunocytomas.
abstract: Passive cutaneous anaphylaxis (PCA) and reversed PCA have been examined in rats bearing IgE or IgG2a immunocytomas. PCA reactivity was completely abolished in rats bearing an IgE immunocytoma, whereas only a slight suppression of PCA reactivity was found in rats bearing an IgG2a immunocytoma. Reversed PCA reactivity was only slightly decreased in rats bearing IgE or IgG2a immunocytomas.
