title: Anti-lymphocytotoxic antibodies in sera of Thai adults infected with Plasmodium falciparum or Plasmodium vivax.
abstract: Because of the potential for the elimination of lymphocytes through anti-lymphocytotoxic antibodies we examined individual sera of patients infected with falciparum or vivax malaria for the presence of antibodies against normal peripheral blood mononuclear cells. In assays done at 15 degrees C, 95% of the P. falciparum patients and 98% of the P. vivax patients showed evidence for antibody activity. Activity at 37 degrees C was significantly less than that at 15 degrees C. These studies suggest that infection with malaria induces anti-lymphocytotoxic antibodies which are predominantly cold-reactive. It is possible that this phenomenon plays a role in modulating the immune response of patients toward malaria.
