As expected, neutrophils represented the predominant leukocyte subset in BAL fluids of S. pneumoniae infected KO onto KO and WT onto KO mice at 24 h post-infection (>96%), while only alveolar recruited neutrophils from WT onto KO, but not KO onto KO mice were found to express Mincle on their cell surface (Fig 6D). This evidence concerns the gene CLEC4E and infection.
