Contrasts in antigen expression in the erythrocytic and exoerythrocytic stages of rodent malaria
Published online by Cambridge University Press: 06 April 2009
Summary
The time and Site of expression of five antigens, recognized by monoclonal antibodies raised against blood-stage parasites, were studied in the exoerythrocytic stage of Plasmodium berghei using indirect immunofluorescent antibody staining. Two monoclonal antibodies (W 3. 5, I 2. 6), which stain the cytoplasm of infected erythrocytes, did not stain the cytoplasm of the infected liver cell but stained the parasite itself suggesting a difference in the antigenic architecture of the erythrocytic and exoerythrocytic parasites. Another antibody (17. 6. 1) revealed a further difference in the antigenic composition of the blood and liver-stage parasites being expressed almost exclusively in the former. Two others (C139 and 17. 3. 9) showed broadly similar patterns of expression in these two stages of the malarial life-cycle.
