Exposure to titanium dioxide (TiO2) nanoparticles (NP) can lead to matrix remodeling, a phenomenon in which Matrix metalloprotease-1 (MMP-1) notably could play an important role. To validate this hypothesis, we 1/ studied MMP-1 expression in human pulmonary fibroblasts after exposure to TiO2 particles of different sizes, shapes and crystal phases and one Carbon Black (CB) NP, and 2/ measured the effect of TiO2 CB NP on an elastase-induced emphysema model in rats.On human lung fibroblasts, some TiO2 NP induced MMP-1 through an interleukin-1β (IL-1β) dependent mechanism, and increased MMP-1 activity. TiO2 micrometric particles induced MMP-1 without IL-1β implication, and CB NP did not induce MMP-1. Rat exposure to TiO2 NP had no effect but ex...
