Also, the expression of inflammatory cytokines, including IL-1β, IL-6, MCP1, and CCL3 were higher in the colon of DSS treated WT to KO compared to KO mice with colitis, revealing that the presence of PARK7/DJ-1 in the immune cells may contribute to DSS-induced inflammation, especially in a colon lacking PARK7/DJ-1 (Figure 6). Here, CCL3 is linked to colitis.
