Effect of Au3/TiO2, Au8/TiO2 and TiO2 NPs (50 µg ml−1, 6 h incubation) on TNF-α and IL-1β secretion by mouse peritoneal macrophages (a,b). Data are expressed as picograms/ml in cell culture medium and are represented as mean ± SEM of 6 independent experiments. #Significantly different from control (p < 0.01).
