Heterogeneity and high plasticity are common features of cells from the mononuclear phagocyte system: monocytes (MOs), macrophages, and dendritic cells (DCs). Upon activation by microbial agents, MO can differentiate into MO‐derived DCs (MODCs). In previous work, we have shown that during acute infection with Plasmodium berghei ANKA (PbA), MODCs become, transiently, the main CD11b+ myeloid population in the spleen (SP) and once recruited to the brain play an important role in the development of experimental cerebral malaria (ECM).

Emerging data has suggested that Tregs, Th17, Th1 and Th2 are correlated with early immune mechanisms by controlling Plasmodium infection. Plasmodium infection appeared to impair the antigen presentation and maturation of DCs, leading to attenuation of specific cellular immune response ultimately. Hence, in this study, we aim to evaluate the relevance between DCs and Tregs/Th17 populations in the process and outcomes of infection with Plasmodium yoelii 17XL (P.y17XL).

NOT Open Access | Plasmodium infection-cure cycles induce modulation of conventional dendritic cells

Malaria is one of the most widespread human infectious diseases worldwide and a cause of mortality. It is difficult to induce immunological memory against malarial parasites, Plasmodium. The immunity to clinical malaria disease is acquired with multiple infection and treatment cycles, along with substantial reduction in parasite burden. However, the mechanism of the acquired immunity remains largely unclear. Conventional dendritic cells (cDCs) play a pivotal role in orchestration of immune responses. The purpose of this study is to analyze the characterization of cDCs after the infection and cure treatment cycles.
