Figure 4. IFNAR−/− and IFrag−/− show elevated serum IFNγ levels during early responses to Pneumocystis lung infection which correlate with induction of bone marrow stress.
IFNγ serum evaluated over the course of Pneumocystis lung infection in IFNAR−/−, IFrag−/−, wildtype and RAG−/− mice at day 0, 7 10 and 16 post infection using a plate based ELISA assay. Figure 4A compares serum IFNγ responses between lymphocyte-competent IFNAR−/− and wildtype mice, Figure 4B compares serum IFNγ responses between lymphocyte-competent IFrag−/− and RAG−/− mice. Statistical analysis was performed using a 2-way ANOVA. Comparisons were made between groups at the same time point. P values are marked as * p< 0.05, ** p<0.01, *** p<0.001.
