Epithelial thymic stromal lymphopoietin (TSLP) promotes Th2 inflammatory responses through induction of OX40 ligand (OX40L) on dendritic cells in allergic rhinitis (AR). Emerging evidence supports the important role of histamine H4 receptor (H4R) in allergic inflammation. This study aimed to investigate the effects of H4R in Th2-cytokine profile mediated by TSLP in AR.
