Figure 3From: Surface coatings of ZnO nanoparticles mitigate differentially a host of transcriptional, protein and signalling responses in primary human olfactory cells Levels of the cytokines IL-6 and IL-8 in hONS cells treated with ZnO nanoparticles. hONS cells from donor A were placed in three replicate wells for each ZnO treatment time-point (2Â h and 6Â h). Results were averaged and expressed relative to levels in time-matched untreated cells set as 100%. * Indicates statistical significance relative to untreated cells.Back to article page
