Abstract

The production in vitro of rye Group I specific IgE antibodies (rye I specific IgE Ab) by human peripheral blood lymphocytes (PBL) was examined. A sensitive enzyme-linked immunosorbent assay was developed which allowed the detection of rye I specific IgE Ab without interference from other immunoglobulin classes. A significant net synthesis of rye I specific IgE Ab by PBL from atopic subjects was detected only during the pollen season, which could not be observed with PBL from non-atopic donors whenever tested. This active synthesis in vitro of IgE antibodies by PBL from atopic patients in season was suppressed when PBL were pre-incubated with the relevant antigen. Furthermore, we are reporting data suggesting an inhibition of the passive release of preformed rye I specific IgE Ab from cells by the specific allergen.

摘要

检测了人外周血淋巴细胞(PBL)体外产生黑麦Ⅰ组特异性IgE抗体(黑麦Ⅰ特异性IgE Ab)的情况。开发了一种灵敏的酶联免疫吸附测定法,该方法可检测黑麦Ⅰ特异性IgE Ab,而不受其他免疫球蛋白类别的干扰。仅在花粉季节检测到特应性受试者的PBL有显著的黑麦Ⅰ特异性IgE Ab净合成,无论何时检测,非特应性供体的PBL均未观察到这种情况。当PBL与相关抗原预孵育时,特应性患者在花粉季节的PBL体外这种IgE抗体的活性合成受到抑制。此外,我们报告的数据表明,特异性变应原可抑制细胞中预先形成的黑麦Ⅰ特异性IgE Ab的被动释放。
