ITGAM and infection: Macrophages (MØ) (Cd11b+Ly6G−Ly6c−Cd11c−MHCII+) and dendritic cells (DC) (Cd11b+Ly6G−Ly6c−Cd11c+MHCIIhi) were sort selected from ear dLN and the spleen of mice infected with LdWT and LdCen−/− at 72 h and 7 d post infection, respectively, and the expression profiles of TLR- 2, 4, and 9 were assessed.
