Sialylation status of leukocyte cell-surface glycoconjugates in streptozotocin-induced diabetic rats and after treatment with agmatine
Journal Title: Current Issues in Pharmacy and Medical Sciences - Year 2013, Vol 26, Issue 4
Abstract
Development of experimental diabetes mellitus in rats was accompanied by increase of desialylation of carbohydrate determinants of leukocyte membrane glycoproteins. A decreased level of both α (2,3)- and α(2,6)-linked sialic acid residues and uncovering the penultimate galactose residues was shown. Our findings shown increase in sialation (in particular α(2,3) sialation) of oligosaccharide sequences of leukocytes membrane glycoconjugates after treatment diabetic rats with agmatine. Detected changes in configuration of leukocyte membrane components in diabetic animals after agmatine administration indicate the positively effects of this polyamine due to its hypoglycemic effect.
