[Monoclonal antibodies against defined Leishmania antigens protect mice against infection by different species of Leishmania].
Mice monoclonal antibodies (IgG) have been raised against Leishmania infantum promastigotes by fusing SP 2/0 myeloma cells and immunized mice splenic cells. The monoclonal antibodies have been detected by indirect immunofluorescence. In vivo tests showed that some of them could inhibit the life cycle of several Leishmania species from the Old and the New World. Studies of these protective monoclonals by the western blot technique showed the presence of three constant antigens (40 kD, 70 kD and 113 kD) amongst the Leishmania species studied.
