CD8+T细胞在过敏性呼吸道疾病发生发展中的作用存在争议。一方面,CD8+T细胞可以抑制哮喘小鼠模型的气道高反应性(AHR)的发展。在人类中,产生IL-10的CD8+T细胞被证明是调节细胞,抑制T细胞的增殖和细胞因子的分泌。另一方面,CD8+T细胞在动物模型中可促进IL-5介导的嗜酸性气道炎症和AHR的发展。为了验证这一点,我们研究了CD8+T细胞在过敏原诱导的AHR诱导过程中的作用,并展示了CD8+T细胞的保护作用。免疫前CD8+T细胞的耗尽导致Th2应答增加和过敏性呼吸道疾病增加。而肺内CD8+T细胞分泌高水平的IL-4、IL-5和IL-10,但分泌少量的干扰素-γ;而支气管周围淋巴结或脾中的CD8+T细胞分泌高水平的干扰素-γ,但很少或不分泌Th2型细胞因子。这些数据显示了CD8+T细胞对诱导免疫反应的保护作用,并显示了致敏小鼠不同部位CD8+T细胞的功能多样性。
The role of CD8+ T cells in the development of allergic airway disease is controversial. On the one hand, CD8+ T cells are known to inhibit the development of airway hyperreactivity (AHR) in murine models of asthma. In humans, IL‐10‐producing CD8+ T cells were shown to act as regulatory cells, inhibiting both proliferation and cytokine secretion of T cells. On the other hand, CD8+ T cells can promote IL‐5‐mediated eosinophilic airway inflammation and the development of AHR in animal models. To examine this, we investigated the role of CD8+ T cells during the induction of allergen‐induced AHR and demonstrated a protective effect of CD8+ T cells. Depletion of CD8+ T cells prior to the immunization led to increased Th2 responses and increased allergic airway disease. However, after development of AHR, CD8+ T cells that infiltrated the lungs secreted high levels of IL‐4, IL‐5 and IL‐10, but little IFN‐γ, whereas CD8+ T cells in the peribronchial lymph nodes or spleen produced high levels of IFN‐γ, but little or no Th2 cytokines. These data demonstrate protective effects of CD8+T cells against the induction of immune responses and show a functional diversity of CD8+ T cells in different compartments of sensitized mice.
