The absolute counts of eosinophils in blood correlated inversely with the peripheral levels of SCF and molecules involved in cell response to viral infection, such as DDX58 (DExD/H-Box Helicase 58, also known as RIG-I), IFNɣ, and CXCL10 (Fig. 4I). The gene discussed is IFNA1; the disease is viral infectious disease.
