PRG2 and allergic disease: In the Inf group, notable upregulated genes included those involved in chemotaxis in myeloid cells (Retnla and Retnlg from the Resistin family and Inpp5j), anti-parasitic defense mechanisms and eosinophil protein synthesis (Prg2; eosinophil major basic protein isoform), differentiation and functional maturation of granulocyte progenitor cells (Cebpe), eosinophil accumulation and survival (Siglecf; sialic acid binding lectin) and inflammation and allergy (Ym1/Chil3; chitinase-like 3 and Alox15).
