Potential use of synthetic α-galactosyl-containing glycotopes of the parasite Trypanosoma cruzi as diagnostic antigens for Chagas disease

Org Biomol Chem. 2013 Sep 14;11(34):5579-83. doi: 10.1039/c3ob40887f.

Abstract

A synthetic glycoarray containing non-reducing α-galactopyranosyl moieties related to mucin O-glycans of the parasite Trypanosoma cruzi was evaluated by a chemiluminescent enzyme-linked immunosorbent assay with sera from patients with chronic Chagas disease. Our data revealed the disaccharide Galα(1,3)Galβ as the immunodominant glycotope, which may eventually be employed as a diagnostic antigen for Chagas disease.
