Regular Voluntary Exercise Potentiates Interleukin-1β and Interleukin-18 Secretion by Increasing Caspase-1 Expression in Murine Macrophages

Figure 9

Effects of regular voluntary exercise (VE) on the protein levels of procaspase-8 in macrophages. Immediately after peritoneal-exudate macrophages were isolated from the sedentary control (SC) and VE mice, whole cellular proteins were extracted. The protein levels of procaspase-8 were analyzed by western blotting (upper panel). The protein levels are presented as ratios relative to the levels of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) (lower panel). Mean ± standard error of the mean (SEM; ) values are provided.
