The total BAL CD45+CD11c+SiglecF+ AMphs population and BAL CD11c+SiglecF+MHC-IIhigh macrophages were studied by flow cytometry one day after the oral treatments with L. rhamnosus CRL1505 and L. plantarum MPL16, two days after the last poly(I:C) stimulation, and two days after the pneumococcal infection (Figure 4 and Figure S4). Here, HLA-C is linked to pneumococcal infection.
