GDV1 induces sexual commitment of malaria parasites by antagonizing HP1-dependent gene silencing (Publications)
Malaria is caused by Plasmodium parasites that proliferate in the bloodstream. During each replication cycle, some parasites differentiate into gametocytes, the only forms able to infect the mosquito vector [...] vector and transmit malaria. Sexual commitment is triggered by activation of AP2-G, the master transcriptional regulator of gametocytogenesis. Heterochromatin protein 1 (HP1)-dependent silencing of ap2-g
Using yeast synthetic lethality to inform drug combination for malaria (Publications)
Combinatorial chemotherapy is necessary for the treatment of malaria. However, finding a suitable partner drug for a new candidate is challenging. Here we develop an algorithm that identifies all of the
The effect of case management and vector-control interventions on space-time patterns of malaria incidence in Uganda (Publications)
space-time patterns of malaria incidence in children < 5 are similar to those of parasitaemia risk predicted from the malaria indicator survey of 2014-15. CONCLUSION: The decline in malaria incidence highlights [...] METHODS: Bayesian spatio-temporal negative binomial models were fitted on district-aggregated monthly malaria cases, reported by two age groups, defined by a cut-off age of 5 years. The effects of interventions [...] trigonometric functions were incorporated in the models to take...
The impact of the scale-up of malaria rapid diagnostic tests on the routine clinical diagnosis procedures for febrile illness: a series of repeated... (Publications)
BACKGROUND: This paper examines the impact of the scale-up of malaria rapid diagnostic tests (RDT) on routine clinical diagnosis procedures for febrile illness in primary healthcare settings in Papua New [...] pre- and post-RDT scale-up and between febrile patients who tested either negative or positive for malaria infection by RDT (post scale-up only). RESULTS: A total of 1809 observations from 120 health facilities [...] scale-up has led to a reduction in body temperature measurement....
Safety, immunogenicity, and protective efficacy against controlled human malaria infection of<em> Plasmodium falciparum</em> sporozoites vaccine in... (Publications)
We are using controlled human malaria infection (CHMI) by direct venous inoculation (DVI) of cryopreserved, infectious Plasmodium falciparum (Pf) sporozoites (SPZ) (PfSPZ Challenge) to try to reduce time [...] time and costs of developing PfSPZ Vaccine to prevent malaria in Africa. Immunization with five doses at 0, 4, 8, 12, and 20 weeks of 2.7 x 10(5) PfSPZ of PfSPZ Vaccine gave 65% vaccine efficacy (VE) at [...] and controls. Antibody responses to Pf circumsporozoite protein were...
The candidate blood-stage malaria vaccine P27A induces a robust humoral response in a fast track to the field phase I trial in exposed and non exposed... (Publications)
The present project aimed at evaluating the safety and immunogenicity of P27A peptide vaccine in malaria non-exposed European and exposed African adults. Methods: This study was designed as a staggered [...] GLA-SE (2.5 or 5mug), or control rabies vaccine (Verorab(R)) were administered intramuscularly to 16 malaria non-exposed and 40 exposed subjects on days 0, 28 and 56. Local and systemic adverse events (AEs) [...] an ADCI dependent mechanism. Incidence of AEs and antibody responses were...
Public health challenges and prospects for malaria control and elimination (Publications)
unprecedented efforts to control malaria, including renewed political and financial commitment and increased availability of both old and new strategies and tools. However, malaria still represents a major health [...] becoming increasingly crucial. Among other needs, common methodologies for estimating and tracking the malaria burden, new strategies to measure transmission, better understanding of immunity, and increased knowledge [...] only on Plasmodium falciparum but also and increasingly on...
