Immunogenicity of whole-parasite vaccines against Plasmodium falciparum involves malarial hemozoin and host TLR9.

Although whole-parasite vaccine strategies for malaria infection have regained attention, their immunological mechanisms of action remain unclear. We find that immunization of mice with a crude blood stage extract of the malaria parasite Plasmodium falciparum elicits parasite antigen-specific immune responses via Toll-like receptor (TLR) 9 and that the malarial heme-detoxification byproduct, he...

Survival strategies of the malarial parasite Plasmodium falciparum

Plasmodium falciparum, the protozoan parasite causing falciparum malaria, is undoubtedly highly versatile when it comes to survival and defence strategies. Strategies adopted by the asexual blood stages of Plasmodium range from unique pathways of nutrient uptake to immune evasion strategies and multiple drug resistance. Studying the survival strategies of Plasmodium could help us envisage strat...

NADPH production by the malarial parasite Plasmodium falciparum.

Two enzymes from Plasmodium falciparum that catalyze the formation of NADPH have been partially purified and characterized. Glutamate dehydrogenase (GDH), molecular mass 230 Kd, pH optimum 7.0, is capable of producing NADPH under optimum conditions at about 10% of the capacity of the host erythrocyte. This capacity increases slightly during the developmental cycle of the parasite. NADP-specific...

A Plasmodium falciparum Host-Targeting Motif Functions in Export during Blood Stage Infection of the Rodent Malarial Parasite Plasmodium berghei

Plasmodium falciparum (P. falciparum) secretes hundreds of proteins--including major virulence proteins--into the host erythrocyte. In order to reach the host cytoplasm, most P. falciparum proteins contain an N terminal host-targeting (HT) motif composed of 11 amino acids. In silico analyses have suggested that the HT motif is conserved throughout the Plasmodium species but experimental evidenc...

Hemozoin Enhances Maturation of Murine Bone Marrow Derived Macrophages and Myeloid Dendritic Cells

Background: Falciparum malaria is a severe health burden worldwide. Antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. Malarial hemozoin (HZ), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. Objective: To determine the immunological impact of hemozoin on the capacity ...
