Abstract
Levels of soluble Fas ligand (sFasL) in serum were elevated in patients with Plasmodium falciparum malaria and showed a significant decline during disease course. sFasL levels that were elevated before antimalarial treatment began correlated significantly with depressed total lymphocyte and T-cell counts. These data suggest that Fas-induced apoptosis might play a role in malaria-associated lymphopenia.
