Monoclonal antibody (mAb) CA7AE binds specifically to the phosphorylated Gal-beta 1,4-Man disaccharide repeat epitope of Leishmania donovani lipophosphoglycan (LPG). This mAb detected the repeat epitope in most but not all of a wide variety of Leishmania species and strains examined. MAb CA7AE also bound to both glycoprotein and carbohydrate antigens in medium from L. donovani promastigote cultures. Specifically, mAb CA7AE bound the delipidated form of LPG, the phosphoglycan, and a glycoprotein both of which are released into the medium by the parasite indicating that both share a specific phosphorylated carbohydrate epitope. The epitope was detected in sera from L. donovani-infected (kala-azar positive) patients when mAb CA7AE was used in an antigen-capture enzyme-linked immunosorbent assay (ELISA). MAb L157 is specific for a protein that is found associated with L. donovani LPG, the lipophosphoglycan-associated protein (LPGAP). This mAb bound to molecules in all 19 strains (representing 9 species) of Leishmania promastigotes and to molecules in 2 species of Trypanosoma procyclic culture forms. This wide distribution of the LPGAP epitope implies that it may have a conserved function, for example, in the biochemistry or arrangement of parasite surface molecules. In addition, since the LPGAP is involved in the stimulation of T lymphocyte proliferation, its wide distribution amongst different Leishmania species suggests that it may be an ideal molecule for testing as a vaccine for leishmaniasis.
