• eliminate ROS, but also up-regulated the Nrf2/HO-1 pathway to maintain redox homeostasis. Depending on the location of the accumulation, nanoantioxidants need to employ different encapsulating or coating strategies. Several studies used neutrophil membranes to increase the specificity of antioxidant

• pretreatment with the nanoformulation resulted in significantly reduced heme oxygenase upregulation as compared to control samples, suggesting a protective effect provided by the nanoparticles. Keywords: α-tocopherol; cryogenic transmission electron microscopy (cryo-TEM); dermocosmetics; HO-1; nanostructured

• the physical and chemical stability, particle size analysis and TOC encapsulation efficiency were periodically evaluated by PCS and HPLC, respectively, as above reported. Western blot analysis for HO-1 and HO-2 protein Cytotoxicity determination Experiments were carried out to assess the range of NLC

• ) signaling pathway was implicated in OS. Data showed that the expression of p38, Jun N-terminal kinase (JNK), NF-κB, Nrf-2, and heme oxygenase (HO-1) was promoted in the brain of TiO2 NPs-treated groups. Simultaneously, levels of O2−, H2O2, MDA, carbonyl, and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were also

• of ZnO particles under submerged and ALI conditions. Interestingly, the response (LDH release, HO-1 induction) occurred more rapidly at the ALI but to a similar extend [37]. Similarly, exposure of A549 cells to ZnO particles at the ALI provoked a stronger increase in pro-inflammatory gene expression
