IL-12对辅助性T细胞1(Th 1)的发育至关重要,并抑制Th 2应答的诱导。特应性疾病的特征是Th 2应答,与组胺的过度产生有关。在这里,我们提出的证据表明,组胺,在生理浓度,强烈抑制人IL-12 p40和p70 mRNA和蛋白质的生产由人单核细胞。特异性组胺受体拮抗剂的使用表明,这种抑制作用是通过H2受体和细胞内cAMP的诱导介导的。IL-12产生的抑制不依赖于IL-10和IFN-γ。组胺强烈减少Th 1-诱导细胞因子IL-12的产生的观察意味着特应性患者中Th 2应答发展的正反馈机制。
IL-12 is essential for T helper 1 (Th1) development and inhibits the induction of Th2 responses. Atopic diseases, which are characterized by Th2 responses, are associated with the overproduction of histamine. Here we present evidence that histamine, at physiological concentrations, strongly inhibits human IL-12 p40 and p70 mRNA and protein production by human monocytes. The use of specific histamine receptor antagonists reveals that this inhibition is mediated via the H2 receptor and induction of intracellular cAMP. The inhibition of IL-12 production is independent of IL-10 and IFN-gamma. The observation that histamine strongly reduces the production of the Th1-inducing cytokine IL-12 implies a positive feedback mechanism for the development of Th2 responses in atopic patients.
