Effects of linagliptin treatment on LPS-induced interleukin IL-6 production after 5 h. Human U937 monocytes were treated with LPS and/or linagliptin. IL-6 levels in the supernatants were determined via ELISA after 5 h of treatment. *P < 0.001 vs. control; †P < 0.001 vs. LPS 1 μg/mL; ‡P < 0.0001 vs. LPS 1 μg/mL. Lina, linagliptin
