Alveolar macrophages

This picture illustrates an example of gut microbiota composition dictating how resident lung alveolar macrophages (AM) respond to viral infection. The presence of segmented filamentous bacteria, a commensal microbe present in some mice, reprograms AM gene expression, increasing complement expression and phagocytosis, thereby enabling AM to engulf and destroy viral pathogens without inflammatory signaling.
