Lack of correlation between LPS-induced IL-1β and ATP release in the THP-1 cell line. Cells were treated as indicated and supernatants were removed at the times indicated. Extracellular ATP concentrations were determined using the firefly luciferase assay (A), and in some samples IL-1β concentrations were determined using an ELISA (B). Data are from one representative experiment, similar results were obtained on two other separate occasions.
