Abstract EN
Innate immunity has an important.
role in the protection against malaria.
To clarify the effect on non lethal and lethal strain of Plasmodium yoelii, compari¬son between two groups of C57BL/6 mice infected with 104 parasitized RBCs was performed.
Liver and spleen mononuclear cells were isolated and analyzed by flow cytometry.
The parasite appeared in blood on day 3 in both strains, with non lethal infection parasitemia reached a peak of 60% on day 14 and mice completely recovered, while in lethal infection parasitemia was 80% on day 7 and mice succumbed to death.
In non lethal strain, mice became anemic and the hematocrit percentage returned to its normal value during recovery, while in the lethal strain mice were severely anemic before death.
The major expanding cells were found to be TCR Intermediate (TCRint) cells, mainly NKl.l'subset, these TCRim cells were distinguished from conventional T cells of thymic origin.
CD4" & CD8" cells increased in both strains.
During malarial infection, the population of conventional T cells did not increase.
and usually associated with thymic atrophy.
The present results showed that TCR'm cells were intimately associated with the protection against malarial infection in both non lethal and lethal strains but the mice died in lethal infection due to the mas¬sive destruction of red blood cells leading to fatal anemia.
Abbreviations: TCR'm cells: intermediate T cell receptor cells; TCRh' cells: high T cell receptor cells; NKT cells: natural killer T cells.
