The result showed that CDC42 WT-, K153Q-, and K153R-overexpressing cells had similar phosphorylation levels of JNK after Salmonella infection, but p38 still had a lower phosphorylation level in CDC42 K153R-overexpressing cells than in CDC42 WT- or CDC42 K153Q-overexpressing cells (Fig 5D). Here, MAPK8 is linked to Salmonella Infections.
