Alveolar macrophages (AM) in the lungs maintain surfactant during homeostasis and respond to infectious pathogens. Here the authors show that in the absence of NKR-P1B, pneumococcal infection is more severe because KO AM have increased rates of lipid surfactant uptake and reduced anti-microbial function.
