The role of leuocytes hearing natural killer complex receptors and killer Immunoglobulin-like receptors in the immunology of malaria

Abstract

The biology of Natural Killer (NK) cells and other NK Receptor (NKR)(+) leukocytes has largely been elucidated in viral or cancer systems, and involvement in other diseases or infectious states is less clearly defined. Recently, however, clear evidence has emerged for a role in malaria. NK cells and NKR(+) leukocytes significantly control susceptibility and resistance to both malaria infection and severe disease syndromes in murine models, in dependence upon receptors encoded within the Natural Killer Complex (NKC). Plasmodium falciparum can rapidly activate human NKR(+) gammadelta T cells and NK cells in vitro, and these responses are controlled partly by NKR loci encoded within the human s..
