Figure 2: RT-qPCR analysis of the transcript expression of the keratinocyte differentiation markers filaggrin and SPRR2A, of the antimicrobial peptides S100A7 and BD-2, and the IL-13RA2 receptor chain after 24 h NHEK treatment by AD or PSO mixes. Results are expressed as percentage of the relative expression of stimulated cells over control cells.
