GATA3 and allergic disease: Furthermore, the hydrolyzed IF promoted the immune response of T helper 1 (Th1) and regulatory T (Treg) cells by enhancing the messenger RNA (mRNA) expression of T‐box transcription factor 21 (T‐bet) and forkhead box protein P3 (Foxp3), which in turn suppressed the T helper 2 (Th2) overexpressed immune response in allergy (GATA‐binding protein 3 (GATA‐3) and retinoic‐acid‐receptor‐related orphan receptor gamma t (RORγt) mRNA expression, as well as interleukin 4 (IL‐4) and interleukin 5 (IL‐5) levels).
