Abstract
Four monoclonal antibodies (MAbs) derived from a Schistosoma mansoni-infected mouse reacted against the tegument or the cell layer of the digestive tract of the adult worm. They also showed similar patterns of immunofluorescence staining when schistosomula were used as antigens. Two of the MAbs (4A10 and 4D3) recognized immune complexes deposited in the kidneys of infected mice and hamsters as detected by indirect and direct immunofluorescence reactions. When adsorbed to polystyrene beads, both MAbs allowed the quantitative detection of antigen by an enzyme immunoassay. 125I-labeled 4A10 binding to live schistosomula and corresponding inhibition assay ruled out the possibility that this binding could be through its Fc fragment. The same MAb detected an antigen migrating as an 80-kilodalton protein by Western blot analysis of soluble worm antigen preparation after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Use of MAb 4A10 may help to elucidate mechanisms of renal pathology and also be of value in the development of immunodiagnostic assays.
