title: Schistosoma mansoni: stimulation of artificial granuloma formation in vivo by carbohydrate determinants.
abstract: A subset of Schistosoma mansoni egg glycoproteins that share a common carbohydrate epitope recognized by monoclonal antibody 128C3 was shown to induced formation of hepatic granulomata when conjugated to Sepharose beads and injected into the portal circulation of naive mice. Concanavalin-binding egg glycoproteins exhibited more granuloma-inducing activity than did total egg extract, although deglycosylated egg proteins also induced granulomata; thus, both amino acid and carbohydrate epitopes appeared to be involved. Glycoproteins derived from adult male worms also were active, indicating that immunological processes responsible for granuloma formation may not be absolutely stage specific.
