Abstract

The production of IL-2 and IL-3 by T cells from mice which had been contact sensitized to TNP and/or tolerized by intravenous injections of TNBS was assayed. Contact sensitization rapidly primes T cells, so that they respond to in vitro restimulation with haptenated syngeneic cells by producing IL-2 and IL-3. This production is strongly inhibited, in an antigen-specific manner, in tolerized mice. At least part of this inhibition can be attributed to the action of suppressor T cells that act by preventing the activation of lymphokine production in vitro. Lymphokine production thus closely parallels the in vivo delayed-type hypersensitivity (DTH) reaction in this system.

摘要

对三硝基苯(TNP)进行接触致敏和/或通过静脉注射三硝基苯磺酸(TNBS)进行耐受处理的小鼠的T细胞中白细胞介素-2(IL-2)和白细胞介素-3(IL-3)的产生情况进行了测定。接触致敏能迅速使T细胞致敏,从而使其在体外受到半抗原化的同基因细胞再次刺激时通过产生IL-2和IL-3做出反应。在耐受处理的小鼠中,这种产生以抗原特异性的方式受到强烈抑制。这种抑制至少部分可归因于抑制性T细胞的作用,这些抑制性T细胞通过阻止体外淋巴因子产生的激活发挥作用。因此,在该系统中,淋巴因子的产生与体内迟发型超敏反应(DTH)密切平行。
