title: Some roles of free radicals in malaria.
abstract: Malaria parasites are very vulnerable to oxidant stress during the part of their life cycle when they inhabit erythrocytes. As the infection progresses they also activate macrophages, one consequence of which is extracellular release of reactive oxygen species. For these reasons free radicals are frequently discussed in the literature on antimalarial drugs, malarial immunity, and disease pathogenesis. They are also central to arguments explaining how the genetic mutations that lead to sickle cell disease, thalassemia and glucose-6-phosphate dehydrogenase have become so common in tropical regions. This review summarizes how these links between free radicals and this disease came to be understood, and the present state of the field.
