Abstract | High levels of circulating immunocomplexes (ICs) are found in patients with either infectious or sterile inflammation. We report that patients with either Plasmodium falciparum or Plasmodium vivax malaria have increased levels of circulating anti-DNA antibodies and ICs containing parasite DNA. Upon stimulation with malaria-induced ICs, monocytes express an NF-κB transcriptional signature. The main source of IC-induced proinflammatory cytokines (i.e., tumor necrosis factor alpha [TNF-α] and interleukin-1β [IL-1β])in peripheral blood mononuclear cells from acute malaria patients was found to be a CD14+ CD16 (FcγRIIIA)+ CD64 (FcγRI)high CD32 (FcγRIIB)low monocyte subset. Monocytes from convalescent patients were predominantly of the classical phenotype (CD14+ CD16−) that produces high levels of IL-10 and lower levels of TNF-α and IL-1β in response to ICs. Finally, we report a novel role for the proinflammatory activity of ICs by demonstrating their ability to induce inflammasome assembly and caspase-1 activation in human monocytes. These findings illuminate our understanding of the pathogenic role of ICs and monocyte subsets and may be relevant for future development of immunity-based interventions with broad applications to systemic inflammatory diseases. | pt_BR |
