Background The interleukin (IL)‐36 cytokines include IL‐36α, IL‐36β, IL‐36γ, and IL‐36Ra. Little was known about their roles in type 2 diabetes mellitus (T2DM). Methods The study included 40 T2DM patients and 42 healthy control subjects. The anthropometric and biochemical measurements were performed using automatic biochemical analyzer, high‐performance liquid chromatography, and electrochemiluminescence immunoassay. Circulating IL‐36α, IL‐36γ, IL‐36Ra, and IL‐17 levels were determined by enzyme‐linked immunosorbent assay. Results Serum IL‐36α, IL‐36γ, and IL‐17 levels in T2DM patients were significantly higher than those in controls, whereas serum IL‐36Ra levels in T2DM patients were lower. Correlation analysis showed that serum IL‐36α was positively correlated with high sensitivity C‐reactive protein. Serum IL‐36α was negatively correlated with IL‐36Ra. Serum IL‐17 was negatively correlated with low‐density lipoprotein cholesterol. Conclusions This study demonstrated that T2DM patients displayed increased IL‐36α and IL‐36γ expression and decreased IL‐36Ra expression. Moreover, the inflammatory cytokine levels were directly proportional to the inflammation and blood lipid levels. Our results suggest that IL‐36 cytokines may be a new target for the diagnosis or treatment of T2DM.
