Differential regulation of beta-chemokines in children with Plasmodium falciparum malaria.

ABSTRACT: Chemokines regulate the host immune response to a variety of infectious pathogens. Since the role of chemokines in regulating host immunity in children with Plasmodium falciparum malaria has not previously been reported, circulating levels of beta-chemokines (MIP-1alpha, MIP-1beta, and RANTES) and their respective transcriptional profiles in ex vivo peripheral blood mononuclear cells (PBMCs) were investigated. Peripheral blood MIP-1alpha and MIP-1beta levels were significantly elevated in mild and severe malaria, while RANTES levels decreased with increasing disease severity. Beta-chemokine gene expression profiles in blood mononuclear cells closely matched those of circulating beta-chemokines, illustrating that PBMCs are a primary source for the observed pattern of beta-chemokine producti
