The number of activated and degranulating eosinophils in the lungs of WT mice increases 2 weeks after i.v. injection (Figure 4), and we observed comparably high levels of CD35/CD21+ and CD69+ activated eosinophils in IL5Tg mice, with a greater abundance of degranulating CD63+ eosinophils in IL5Tg mice 2 weeks after tumor cell injection (Supplemental Figure 7C). The gene discussed is CR2; the disease is neoplasm.
