Extent of IL-1β production and active caspase-1 by PMA-primed THP-1 cells in the presence of silver materials.

<p>(A) Differences in the levels of IL-1β production induced by different forms of silver materials. The cells were treated with different silver materials for 24 h. Data are represented as the mean ±SD (n = 3). (B) Difference in the levels of caspase-1 activity. The cells were treated with 200 µg/mL of silver materials for 24 h. Data are represented as the mean ±SD (n = 3). (C) Differences in the levels of caspase-1 mRNA expression levels. The cells were treated with 100 µg/mL of silver materials for 24 h. (D) Differences in the levels of caspase-1 mRNA expression. The cells were treated with 100 µg/mL of silver materials for 24 h.
