Structural basis of malaria RIFIN binding by LILRB1-containing antibodies (Publications)
Some Plasmodium falciparum repetitive interspersed families of polypeptides (RIFINs)—variant surface antigens that are expressed on infected erythrocytes1—bind to the inhibitory receptor LAIR1, and in
Malaria in Angola: recent progress, challenges and future opportunities using parasite demography studies (Publications)
of malaria interventions has occurred at the national level in Angola, together with cross-border initiatives and regional efforts in southern Africa. Currently, Angola aims to consolidate malaria control [...] heterogeneity in malaria prevalence among Angolan provinces, as well as internal population movements and migration across borders, represent major challenges for the Angolan National Malaria Control Programme [...] Programme. This review aims to contribute to the understanding of factors...
Health system readiness and the implementation of rectal artesunate for severe malaria in sub-Saharan Africa: an analysis of real-world costs and... (Publications)
BACKGROUND: Rectal artesunate, an efficacious pre-referral treatment for severe malaria in children, was deployed at scale in Uganda, Nigeria, and DR Congo. In addition to distributing rectal artesunate [...] tion required additional investments in crucial but neglected components in the care for severe malaria. We examined the real-world costs and constraints to rectal artesunate implementation. METHODS: We [...] annual cost of rectal artesunate implementation per child younger than 5 years at...
Novel 3-trifluoromethyl-1,2,4-oxadiazole analogues of astemizole with multi-stage antiplasmodium activity and <em>in vivo</em> efficacy in a... (Publications)
Iterative medicinal chemistry optimization of an ester-containing astemizole (AST) analogue 1 with an associated metabolic instability liability led to the identification of a highly potent 3-trifluor
New derivatives of the multi-stage active Malaria Box compound MMV030666 and their antiplasmodial potencies (Publications)
MMV’s Malaria Box compound MMV030666 shows multi-stage activity against various strains of Plasmodium falciparum and lacks resistance development. To evaluate the importance of its diarylether partial
Infectivity of symptomatic malaria patients to <em>Anopheles farauti</em> colony mosquitoes in Papua New Guinea (Publications)
to mosquitoes is an understudied bottleneck in the transmission of malaria. Direct membrane feeding assays (DMFA) allow detailed malaria transmission studies from humans to mosquitoes. Especially for Plasmodium [...] were performed with venous blood collected from rapid diagnostic test (RDT) positive symptomatic malaria patients and subsequently analysed by light microscopy and quantitative real time polymerase chain
Emulator-based Bayesian optimization for efficient multi-objective calibration of an individual-based model of malaria (Publications)
framework employing Gaussian process or machine learning emulator functions to calibrate a complex malaria transmission simulator. We demonstrate our approach by optimizing over a high-dimensional parameter [...] a portfolio of multiple fitting objectives built from datasets capturing the natural history of malaria transmission and disease progression. Our approach quickly outperforms previous calibrations, yielding
Revisiting the effect of pharmaceuticals on transmission stage formation in the malaria parasite <em>Plasmodium falciparum</em> (Publications)
Malaria parasites rely on specialized stages, called gametocytes, to ensure human-to-human transmission. The formation of these sexual precursor cells is initiated by commitment of blood stage parasites [...] vivo. These observations suggest that therapeutic interventions may promote gametocytogenesis and malaria transmission. Here, we engineered a P. falciparum reporter line to quantify sexual commitment rates [...] rates after exposure to antimalarials and other pharmaceuticals commonly...
Multi-insecticide resistant malaria vectors in the field remain susceptible to malathion, despite the presence of <em>Ace1</em> point mutations (Publications)
Insecticide resistance in Anopheles mosquitoes is seriously threatening the success of insecticide-based malaria vector control. Surveillance of insecticide resistance in mosquito populations and identifying the
