CD4 and Alzheimer disease: Again, the IFNγ mRNA expression levels and the percentage of IFNγ-producing CD4+ immune cells in the CP APP−/− mESC-TEP-transplanted AD mice were higher than those in APP+/+ mESC-TEP-transplanted AD mice (Figures 6A,B), consistent with the results for the percentage of IFNγ-producing CD4+ splenic T cells among the mice (Figure 4E).
