BACKGROUND The effects of Plasmodium falciparum on B-cell homeostasis have not been well characterized. This study investigated whether an episode of acute malaria in young children results in changes in the peripheral B cell phenotype. METHODS Using flow-cytofluorimetric analysis, the B cell phenotypes found in the peripheral blood of children aged 2-5(More)
BACKGROUND Plasmodium falciparum infection leads to alterations in B cell subset distribution. During infancy, development of peripheral B cell subsets is also occurring. However, it is unknown if infants living a malaria endemic region have alterations in B cell subsets that is independent of an age effect. METHODS To evaluate the impact of exposure to(More)
BACKGROUND Endemic Burkitt's lymphoma (BL) is an extranodal tumor appearing predominantly in the jaw in younger children while abdominal tumors predominate with increasing age. Previous studies have identified elevated levels of antibodies to Plasmodium falciparum schizont extracts and Epstein-Barr virus (EBV) viral capsid antigens (VCA) in endemic BL(More)
Epstein Barr virus (EBV) is a gammaherpesvirus that is associated with nasopharyngeal carcinoma (NPC) and endemic Burkitt lymphoma (eBL). EBV carries several latent genes that contribute to oncogenesis including the latent membrane protein 1 (LMP-1), a known oncogene and constitutively active CD40 homolog. Variation in the C terminal region of LMP-1 has(More)
Background Endemic Burkitt's lymphoma, the most prevalent childhood cancer in Equatorial Africa, is a rapidly growing B-cell malignancy that is ultimately fatal if untreated. Two co-factors are linked to the etiology of this pedia-tric cancer: Epstein-Barr virus (EBV) infection, and sustained and intense exposure to Plasmodium falciparum malaria(More)
