Galactocerebrosides are antigens for immunoglobulins in sera of an experimental model of trypanosomiasis in sheep

In an experimental model of human African trypanosomiasis in sheep inoculated with Trypanosoma brucei brucei, we report an immunoglobulin reactivity towards central nervous system (CNS) glycolipids. Immunocharacterization of the glycolipid antigens was performed on thin-layer chromatography using pe...

description In an experimental model of human African trypanosomiasis in sheep inoculated with Trypanosoma brucei brucei, we report an immunoglobulin reactivity towards central nervous system (CNS) glycolipids. Immunocharacterization of the glycolipid antigens was performed on thin-layer chromatography using peroxidase-labelled second antibody. An immunoreactivity against galactocerebroside antigens was observed in inoculated animals up to a dilution of 1 : 600 and was suppressed after immunoadsorption of sera on pure galactocerebrosides. As galactocerebroside antigen is responsible for demyelination in several experimental models, the relation between the important glycolipid immunoreactivity in inoculated sheep sera and the pathogenesis of CNS demyelination in African trypanosomiasis is suggested.
