Human exposure to engineered nanoparticles has been linked to pleural effusion, inflammation and fibrosis. Silver nanoparticles (AgNPs) are widely used in medical and domestic products, increasing the risk of occupational and domestic exposure. We assessed the influence of AgNPs on adhesion and proliferation of sheep primary pleural mesothelial cells. Cells were used for cell adhesion (90 min) and proliferation experiments (3 days) while exposed to 20 nm and 60 nm AgNPs (0.2 μg/ml and 2 μg/ml) using colorimetric assays. Exposure to 0.2 μg/ml of 20 nm and 60 nm AgNPs significantly increased cell adhesion, while at 2 μg/ml this effect was not elicited. Cell proliferation was significantly increased by both 20 nm and 60 nm AgNPs at 0.2 μg/ml, while at 2 μg/ml this effect was only elicited by the 60 nm AgNPs. AgNPs alter the adhesive and proliferative properties of primary pleural mesothelial cells.
