Consequently, when PMs were gated as a single population based on CD11b and F4/80 expression (Figure 2), as shown in Figures 2B,C, the MHC class I level in PMs of the Msmg-PPE38 group was significantly lower than that in the PMs of the Msmeg-V group at 6 h post infection (hpi) and 1 day post infection (dpi). The gene discussed is ITGAM; the disease is infection.
