The phenotype of BAL macrophages (F4/80+, Ly-6G−, CD11b+ cells) was also evaluated by flow cytometry at days 10 and 14 post-infection and no difference between ChemR23 KO and WT mice were seen for CD209a (DC-SIGN) expression as a marker of the alternatively activated and anti-inflammatory “M2” subset (data not shown). The gene discussed is CMKLR1; the disease is infection.
