CIITA and parasitic infectious disease: Interestingly, the expression levels of some highly regulated genes predicted to inhibit parasitic infection which include antigen representing MHC class II molecules (H2-AB1, H2-AA, CIITA and H2-EB1), IFNγ induced GTPases (IIGP1, IGTP, GBP2, GBP8, GBP11, GBP6 and GBP4) and chemokines (CXCL10 and CXCL9) does not differ between day 45 PI and day 93 PI (Figure 3B).
