本手稿描述了一个协议,用于确定暴露于臭氧(一种标准空气污染物)是否会损害体内的藻体细胞体细胞化。该协议利用常用试剂和技术,可适用于多种肺损伤模型,以确定对肺泡巨噬细胞细胞病的影响。

此处描述的协议测量了接触标准空气污染物臭氧后肺巨噬细胞功能。这些数据表明,臭氧暴露可减少肺动脉巨噬细胞增多,从而成为臭氧水平升高增加肺部疾病发病率的一个机制。这项技术的主要优点是,它允许在体内评估肺功能巨噬细胞功能,而无需对巨噬细胞进行任何可能改变其表型或功能的外体操作。

这项技术揭示了一种新的机制,即肺部在空气污染暴露后无法自我修复。此外,这项技术可能揭示出改变肺部肺功能瘤靶点的新途径。此方法可应用于任何肺损伤或炎症模型。
