Abstract

The presence of migration inhibitory (MI) activity was investigated in the delayed hypersensitivity (DH) reaction induced by i.p. injection of PPD into FCA-sensitized guinea-pigs. Peritoneal exudates were studied at several times before and after the induction of the DH reaction and a non-immune control inflammation. Lymphokine (LK) fractions were prepared from individual exudates and tested in a conventional macrophage migration inhibition assay at concentrations determined to occur in vivo. The results suggest a continuous local production of MI activity and an augmented production during development of a DH reaction.

摘要

通过腹腔注射结核菌素纯蛋白衍生物(PPD)至弗氏完全佐剂(FCA)致敏的豚鼠体内诱导迟发型超敏反应(DH),研究其中迁移抑制(MI)活性的存在情况。在诱导DH反应和非免疫对照炎症之前及之后的多个时间点对腹腔渗出液进行研究。从各个渗出液中制备淋巴细胞因子(LK)组分,并在传统的巨噬细胞迁移抑制试验中,以体内测定的浓度进行检测。结果表明MI活性存在持续的局部产生,且在DH反应发展过程中产生增加。
