Interestingly, infiltration of CD11bhighCD11chigh dendritic cells, CD11b+CD11cint monocytes and small macrophages, CD11b+Gr-1+ neutrophils and CD11b-CD11c+F4/80+ alveolar macrophages into the bronchoalveolar space increased markedly in mice infected with S. rugosus at 2 days post-infection while these cells presented the highest recruitment at 5 days post-infection in S. rotundus-infected mice (Fig. 10). Here, ITGAM is linked to infection.
