Next, we found increased mRNA expression and activity levels of Arg1, mRNA expression of Fizz, Chi3l3, Cd209d, Cd209e, Mrc2 (Cd206), Marco, Il13, Saa1 (Serum amyloid A1 protein), Ccl17, Ccl19, Ccl20, Ccl22, and Ccl24 in Stat2−/− mice compared to WT mice during super-infection (Figures 3G–K). The gene discussed is SAA1; the disease is infection.
