T细胞介导的炎症反应的起始、强度和持续时间取决于T淋巴细胞上特异性受体介导的激活和抑制信号的协调。最近描述的受体,B和T淋巴细胞衰减因子(BTLA),已被证明在限制过敏性哮喘小鼠模型的炎症持续时间中具有重要作用。在这项研究中,我们研究了BTLA对T细胞增殖,募集和存活的作用,以响应吸入过敏原。我们发现,BTLA缺陷小鼠的T细胞中细胞死亡减少,而增殖和肺的招募没有变化。因此,通过BTLA信号传导调节细胞死亡是肺中炎症反应的关键决定因素。
The initiation, intensity and duration of T cell directed inflammatory responses are dependent upon the coordination of both activating and inhibitory signals mediated by specific receptors on the T lymphocyte. The recently described receptor, B and T Lymphocyte Attenuator (BTLA), has been demonstrated to have an important role in limiting the duration of inflammation in a murine model of allergic asthma. In this study we have examined the role of BTLA on the proliferation, recruitment and survival of T cells in response to inhaled allergen. We find that there is decreased cell death in T cells from BTLA-deficient mice, whereas proliferation and recruitment to the lungs are unchanged. Thus, the regulation of cell death through BTLA signaling is a key determinant of the inflammatory response in the lung.
