特发性肺纤维化(IPF)是一种纤维化肺部疾病,病因不明,治疗方案不理想。先前的报道表明,增加的T细胞数量和CD28null表型可预测IPF的预后,这表明这些细胞可能在该疾病中起作用。肺细胞悬浮液的流式细胞分析显示,相对于正常肺外植体,IPF中CD8+ CD28null T细胞显著增加。从IPF肺外植体中分离的CD3+ T细胞转录组学分析显示,相对于正常T细胞,IPF中CD28转录物表达缺失,促炎细胞因子表达升高。IPF肺外植体衍生的T细胞(富集CD28null T细胞),而非正常供体肺CD28+ T细胞诱导人源化NSG小鼠地塞米松抗性肺重构。最后,与CD28+ T细胞相比,CD28null T细胞表达相似的CTLA4和显著更高水平的PD-1蛋白,并且在人源化NSG小鼠中,使用抗CTLA4或抗pd1单抗治疗阻断这两种蛋白会加速肺纤维化。总之,这些结果表明,IPF CD28null T细胞可能促进肺纤维化,但免疫检查点蛋白CTLA-4和PD-1似乎限制了这种作用。
Idiopathic pulmonary fibrosis (IPF) is a fibrotic lung disease, with unknown etiopathogenesis and suboptimal therapeutic options. Previous reports have shown that increased T cell numbers and CD28null phenotype is predictive of prognosis in IPF, suggesting that these cells might have a role in this disease. Flow cytometric analysis of explanted lung cellular suspensions showed a significant increase in CD8+ CD28null T cells in IPF relative to normal lung explants. Transcriptomic analysis of CD3+ T cells isolated from IPF lungs explants revealed a loss of CD28 transcript expression and elevation of proinflammatory cytokine expression in IPF relative to normal T cells. IPF lung explant derived T cells (enriched with CD28null T cells), but not normal donor lung CD28+ T cells induced dexamethasone resistant lung remodeling in humanized NSG mice. Finally, CD28null T cells expressed similar CTLA4 and significantly higher levels of PD-1 proteins relative to CD28+ T cells and blockade of either proteins in humanized NSG mice, using anti-CTLA4, or anti-PD1, mAb treatment accelerated lung fibrosis. Together, these results demonstrate that IPF CD28null T cells may promote lung fibrosis but the immune checkpoint proteins, CTLA-4 and PD-1, appears to limit this effect.
