Figure 2.

IL-1β production in HaCaT and NCTC 2544 keratinocytes treated with SDS alone and in combination with DHA delivered or not through RV-SLNs. (A): HaCaT cells; (B): NCTC 2544 cells. The cells were treated with free DHA or DHA-RV-SLNs (10 or 30 µM) in the absence or in the presence of 50 µg/mL SDS for 48 (left panels) or 72 h (right panels). Data are the means ± SD of three different experiments. Values not sharing the same superscript letter are significantly different (p < 0.05, one-way ANOVA followed by Tukey’s test).
