Angiostrongylus cantonensis is a parasitic nematode and the main causative agent of human cerebral eosinophilic meningoencephalitis (EoM). A definitive diagnosis of EoM usually requires serologic or molecular analysis of the patient's clinical sample. Currently， a 31 kDa antigen is used in immunological tests for this purpose， however as a crude antigen preparation it may present cross-reactivity with other helminthic infections， especially echinococcosis. Heterologous expression studies using prokaryotic systems failed on producing antigenic proteins. The aim of this study was to express and purify three recombinant glycoproteins representing A. cantonensis antigens: ES-7， Lec-5， and 14-3-3， in Chinese hamster ovary (CHO) cells and ES-7 in human embryonic kidney (HEK) cells to develop a source of specific antigens to be used in the diagnosis of angiostrongyliasis. The potential diagnostic value of these three proteins was subsequently characterized in one- and two-dimensional electrophoresis and Western blot to dot blot analyses， with Angiostrongylus-positive sera， normal human sera (NHS)， and a pool of Echinococcus-positive sera (included as a specificity control) used for detection. In addition， recognition of these three proteins following treatment with N-glycosidase F was examined. The ES-7 proteins that were expressed in HEK and CHO cells， and the Lec-5 protein that was expressed in CHO cells， were specifically recognized by A. cantonensis-positive sera in the 2D electrophoresis analysis. This recognition was shown to be dependent on the presence of glycidic portions， making mammalian cells a very promising source of heterologous expression antigenic proteins from Angiostrongylus.
