Abstrakt:	Interleukin-10 production and lung neutrophil infiltration are two essential components of the balanced immune response to pneumonia caused by Streptococcus pneumoniae . Here we describe the existence of two neutrophil subsets in lungs during experimental S. pneumoniae infection in mice, which have different size, granularity and expression of activation markers. During infection, both neutrophils subsets were increased in the lungs of IL-10 producing mice, however this increment was significantly higher in the absence of this cytokine. These results suggest that IL-10 is a key cytokine that regulates lung inflammation during bacterial infection caused by specific neutrophil subsets infiltrating the lungs.
