From: Nano-titanium dioxide modulates the dermal sensitization potency of DNCB
Lymphocyte cytokine production after 0.1% DNCB dermal sensitization or AOO treatment with prior injection of 0.04 mg/ml TiO2 or vehicle. On day 5, the auricular lymph nodes are removed and lymphocytes are cultured for 42 h in the presence of ConA. Cytokines are determined in LNC supernatant. Graphs show mean ± SD, n = 10–12, *p < 0.05, ** p < 0.01 and *** p < 0.001.
