IL4 and type 2 diabetes mellitus: On the first postinfection day, no significant difference was found in concentrations of TNF-α, IL-2, IL-10, IL-12, GM-CSF, and MCP-l between the T2DM group and control group, but significantly higher IL-4 level (mean 1.02 ± 0.2 pg/mL versus 0.52 ± 0.13 pg/mL; P = 0.049) was detected in the T2DM group (Figure 1).
