Alveolar macrophages (AM), which are enhanced by GM-SCF, are an essential piece of the innate immune response and are known to contribute to host defense against flu infections in animal models.

Damage from atmospheric fine particles (PM2.5) in isolated DNA of alveolar macrophages of rats in Taiyuan City was studied applying single cell gel electrophoresis technique.

Objective To study the molecular mechanism of the conversion of alveolar macrophages (AMs) from immune defensive cells to effective cells in mice with endotoxin induced lung injury.
