Figure 5. Caspase-1 activation alone does not sensitize resistant macrophages to LT.
(A) C57BL/6J BMDM were primed with LPS for 2 h, followed by medium removal, and addition of nigericin (5 μM) for 25 min. Caspase-1 and IL-1β were monitored in cell lysates by Western blotting. (B) DBA/2J and C57BL/6J BMDM were treated with LPS and 5 μM nigericin as in (A). LT was then added, and cell viability was determined 2.5 h later by MTT staining.
