M2 Phenotype

Our studies reveal that Streptococcus pneumoniae (pneumococcus) (pEVs) are internalized by macrophages, T cells, and epithelial cells. In vitro , pEVs induce NF-κB activation in a dosage-dependent manner and polarize human macrophages to an alternative (M2) phenotype. In addition, pEV pretreatment conditions macrophages to increase bacteria uptake and such macrophages may act as a reservoir for pneumococcal cells by increasing survival of the phagocytosed bacteria.
