This report describes the development of an assay system which overcomes the difficulty of detecting immune responses of patients with Trichomonas vaginitis by making use of peripheral blood leukocytes obtained from such patients. When peripheral blood leukocytes from the patient were stimulated in microcultures with the soluble antigen extracted from Trichomonas vaginalis, significant degrees of proliferation ensued, as measured by the incorporation of [methyl-3H]thymidine 4 to 5 days after initiation. The antigen-induced proliferation response of peripheral blood leukocytes is specific for T. vaginalis antigen. The T. vaginalis-specific [methyl-3H]thymidine incorporation is mediated by Leu-1-positive cells, namely, T lymphocytes, in the peripheral blood leukocyte population. This assay system should prove useful for the analysis of the immune response to the protozoa in patients with Trichomonas vaginitis.
本报告描述了一种检测系统的开发,该系统通过利用从滴虫性阴道炎患者获取的外周血白细胞,克服了检测此类患者免疫反应的困难。当用从阴道毛滴虫中提取的可溶性抗原在微量培养中刺激患者的外周血白细胞时,在培养开始后4至5天通过[甲基-3H]胸腺嘧啶核苷掺入量测定,会出现显著程度的增殖。外周血白细胞的抗原诱导增殖反应对阴道毛滴虫抗原具有特异性。阴道毛滴虫特异性的[甲基-3H]胸腺嘧啶核苷掺入是由外周血白细胞群体中Leu-1阳性细胞,即T淋巴细胞介导的。该检测系统应证明对分析滴虫性阴道炎患者对该原生动物的免疫反应有用。
