pubmed:abstractText |
Previous passive antibody transfer experiments have indicated that immunity to a 46-kilodalton membrane glycoprotein (M-2) of Leishmania amazonensis may protect against infection with this parasite. In the studies described in this paper, we investigated the ability of the purified M-2 molecule to elicit a protective immune response in conjunction with Freund incomplete and complete adjuvants, saponin, and Corynebacterium parvum. Both relatively susceptible (BALB/c and CBA) and resistant (C57BL/6) strains of mice were examined. C. parvum appeared to be the most effective adjuvant in the three mouse strains tested. The level of protection varied with the mouse strain, although all animals received identical preparations of antigen and adjuvant. Immunization of CBA mice with the M-2 glycoprotein and C. parvum resulted in complete protection against a challenge infection of 10(4) and 10(6) late log-phase promastigotes of L. amazonensis. In the BALB/c strain, complete protection was observed in some of the immunized animals (28 to 50%); in the rest of the mice the onset of infection was significantly delayed. Protective immunity for C57BL/6 mice was observed only at the low infecting dose (10(4) L. amazonensis organisms). The level of protection observed is reflected by increased antibody response (immunoglobulins G1 and G2) developed to the M-2 molecule. The relationship of pure T-cell (nonantibody) immunity to this protection remains to be elucidated.
