靶向扩大致病记忆免疫细胞是预防慢性自身免疫攻击的一种有前途的治疗策略。在这里,我们研究了新的抗人IL-7Rα单抗在非人类灵长类动物中的治疗效果和机制,并表明,根据目标表位的不同,一次注射拮抗性抗IL-7Rα单抗可以在预敏猴子中诱导长期的皮肤炎症控制,尽管反复抗原挑战。未观察到外周血中T细胞数量、表型、功能或代谢的改变,也未观察到体外多克隆刺激的反应。然而,体内长期的低反应性与在体外抗原重新刺激时产生干扰素-γ的抗原特异性T细胞的频率显著降低有关。这些结果表明,抗IL-7Rα单抗可以控制慢性抗原特异性记忆性T细胞应答,促进和维持T细胞介导的慢性炎症性疾病的缓解。慢性炎症通常涉及记忆获得性免疫的重新激活。在这里,作者使用非人类灵长类动物模型表明,单剂量的抗IL-7受体单抗具有拮抗剂而不是激动剂的特性,可以减少抗原特异性T细胞的频率,以帮助抑制慢性皮肤炎症。
Targeting the expansion of pathogenic memory immune cells is a promising therapeutic strategy to prevent chronic autoimmune attacks. Here we investigate the therapeutic efficacy and mechanism of new anti-human IL-7Rα monoclonal antibodies (mAb) in non-human primates and show that, depending on the target epitope, a single injection of antagonistic anti-IL-7Rα mAbs induces a long-term control of skin inflammation despite repeated antigen challenges in presensitized monkeys. No modification in T cell numbers, phenotype, function or metabolism is observed in the peripheral blood or in response to polyclonal stimulation ex vivo. However, long-term in vivo hyporesponsiveness is associated with a significant decrease in the frequency of antigen-specific T cells producing IFN-γ upon antigen restimulation ex vivo. These findings indicate that chronic antigen-specific memory T cell responses can be controlled by anti-IL-7Rα mAbs, promoting and maintaining remission in T-cell mediated chronic inflammatory diseases. Chronic inflammation often involves reactivation of memory adaptive immune. Here the authors show, using non-human primate models, that a single dose of anti-IL-7 receptor monoclonal antibody that exhibits antagonist but not agonist properties can reduce the frequency of antigen-specific T cell to help repress chronic skin inflammation.
