Generally, MCP-1 levels showed a tendency towards a small postprandial decrease on most study days; however, these changes were only significant for the type 2 diabetes group at 1 wk (P = 0.001) and 1 yr (P < 0.0001) and for the NGT group at 3 mo (P = 0.009) (Figure 1(b)). Here, CCL2 is linked to type 2 diabetes mellitus.
