IL-1β release following 24-h exposure to TiO
nanobelts in comparative murine AM cultures co-stimulated with 20 ng/mL LPS. Data indicate mean ± SEM IL-1β release in isolated culture media. Asterisks indicate significance at ***P < 0.001, or *P < 0.05 compared to no particle 0 μg/ml condition. Daggers indicate significance at ††† P < 0.001 compared to the -COOH TiO2 nanobelt (-COOH TNB) exposure in the Balb/c AM. Symbols indicate significance at §§§ P < 0.001, or §§ P < 0.01 compared to the C57BL/6 AM TiO2 nanobelt (TNB) exposure condition.
