为了研究CD 8 + T细胞在过敏性致敏中的作用,我们研究了致敏前体内CD 8 + T细胞耗竭对IgE产生、速发型皮肤超敏反应和气道反应性改变的影响。将BALB/c小鼠胸腺切除并用抗CD 8抗体处理,导致脾和淋巴组织中的CD 8 + T细胞(<1%)耗竭。在这些小鼠中,通过气道对卵清蛋白(OVA)致敏仍然导致IgE抗OVA反应和对OVA的立即皮肤反应,但动物不能发展为气道高反应性、肺实质嗜酸性粒细胞浸润或气道局部淋巴结中的IL-5产生。在致敏过程中(10-d方案的第8天)从幼稚动物转移CD 8 + T细胞完全恢复了发展气道高反应性的能力,这伴随着IL-5的产生和肺中嗜酸性粒细胞的积累。这些数据表明CD 8 + T细胞在IL-5的产生和通过气道的抗原致敏后气道反应性改变的发展中起关键作用。
To study the role of CD8+ T cells in allergic sensitization, we examined the effects of in vivo depletion of CD8+ T cells prior to sensitization on IgE production, immediate type cutaneous hypersensitivity and development of altered airway responsiveness. BALB/c mice were thymectomized and treated with anti-CD8 antibody resulting in depletion of CD8+ T cells (<1%) in spleen and lymphoid tissues. In these mice, sensitization to ovalbumin (OVA) via the airways still resulted in IgE anti-OVA responses and immediate cutaneous reactions to OVA, but the animals were unable to develop airway hyperresponsiveness, eosinophil infiltration of the lung parenchyma, or IL-5 production in the local lymph nodes of the airway. Transfer of CD8+ T cells from naive animals during sensitization (on day 8 of the 10-d protocol) fully restored the ability to develop airway hyperresponsiveness and this was accompanied by IL-5 production and eosinophil accumulation in the lung. These data indicate a critical role for CD8+ T cells in the production of IL-5 and the development of altered airway responsiveness after antigen sensitization through the airways.
