Expression of the filaggrin (FLG) gene in normal human epidermal keratinocytes (NHEKs) treated with interleukin (IL)-22 and L-glutamic acid-L-tryptophan (L-Glu-L-Trp). (A) Relative gene expression levels of FLG in NHEKs treated with IL-22 (10 or 100 ng/mL) and L-Glu-L-Trp (0.004%). Data are presented as means ± SD. n = 3. (B) Schematic of the experiments for pre- or post-treatment with L-Glu-L-Trp. (left). Relative gene expression levels of FLG in NHEKs treated with IL-22 (10 ng/mL) or L-Glu-L-Trp (0.004%) (right). Data are presented as means ± SD. n = 3. ∗∗p < 0.01.
