Fig 2. Levels of proteins from family 18 of glycosyl hydrolase in neutrophils of patients with type 2 diabetes in tertiles of increasing activity of leukocyte elastase.

CHIT1—chitotriosidase activity expressed in nmol/h/10⁶ cells, AMCase—acidic mammalian chitinase activity expressed in nmol/h/10⁶ cells,YKL-40—chitinase 3-like protein 1 concentration expressed in ng/10⁶ cells,T1-T3—subgroups of patients divided according to tertiles of increasing activity of leukocyte elastase in neutrophils (for details see Material and methods section). On the y-axis appropriate units reflecting levels of examined proteins are indicated.
