Identification of a compensatory mutant (lpg2-REV) of Leishmania major able to survive as amastigotes within macrophages without LPG2-dependent glycoconjugates and its significance to virulence and immunization strategies.

Abstract excerpt

Different Leishmania species rely to different extents on abundant glycoconjugates, such as lipophosphoglycan (LPG) and related molecules, in mammalian infections. Previously, we showed that Leishmania major deletion mutants lacking the Golgi GDP-mannose transporter LPG2, which is required for assembly of the dominant phosphoglycan (PG) repeats of LPG, were unable to survive in macrophages. These lpg2- mutants,...
