Abstract
Contact sensitization by epicutaneous application of picryl chloride causes in mice a significant reduction of the antibody responses to immunogenic TNP-conjugates. This split unresponsiveness is along-lasting. It was found that hapten applied on the skin became attached to the serum proteins and the transfer of such a serum into normal recipients, while not influencing the ability of these animals to become contact-sensitized to PCl, rendered them unable to mount the anti-TNP antibody response. Possible mechanisms of split unresponsiveness to the TNP determinant induced by PCl treatment are suggested.
摘要
通过皮内涂抹苦味酸氯在小鼠中引起的接触致敏会导致对免疫原性三硝基苯（TNP）偶联物的抗体反应显著降低。这种分裂性无反应状态持续时间很长。研究发现，涂抹在皮肤上的半抗原会附着在血清蛋白上，将这种血清转移到正常受体中，虽然不会影响这些动物对苦味酸氯产生接触致敏的能力，但会使它们无法产生抗TNP抗体反应。文中提出了苦味酸氯处理诱导对TNP决定簇产生分裂性无反应状态的可能机制。
