NLRP3 and infection: In contrast, no significant difference in the percentage of N. caninum infected cells was found between NAC pre-treated Nlrp3−/− PMs and the infection-only Nlrp3−/− PMs, though PG did cause a slight decrease in Nlrp3−/− PMs (WT: F(2, 6) = 94.42, P < 0.0001; Nlrp3−/−: F(2, 6) = 48.37, P = 0.0002; Fig. 5b).
