More profound upregulation of POSTN, TNC, LUM, FN1, COL6A1, COL6A2, COL6A3, and COL1A2 in ACTA2− cells treated with IL-13 is consistent with scRNA-seq DEG showing upregulation of these genes in F_B vs. F_A subpopulation in active EoE. The gene discussed is FN1; the disease is eosinophilic esophagitis.
