Study finds tafenoquine is a cost-effective treatment option for malaria
by Menzies School of Health Research Map of incremental cost-effectiveness ratios (ICERs) in each malaria-endemic municipality for Scenario 1 (tafenoquine for adults, primaquine adherence 66.7%), Scenario 2 (tafenoquine for all, primaquine adherence 66.7%), Scenario 3 (tafenoquine for adults, high primaquine adherence of 90%), and Scenario 4 (tafenoquine for adults, low primaquine adherence of 30%), compared to...

Killing is their job: Two studies analyze natural killer cells as they tackle the worst form of malaria
by Delthia Ricks, Medical Xpress Antibody-mediated NK cell activity in children: (A) Merozoite opsonizing antibodies from Junju adults (n=40) induced a significantly higher proportion of ab-NK cells degranulation compared to Junju children (n=293). Hyperimmune (PHIS) and malaria naive plasma were included as positive and negative controls, respectively. Error bars represent a 95% confidence interval of...
Antibody treatment tested as new tool against malaria
by Carla K. Johnson This 2014 photo made available by the U.S. Centers for Disease Control and Prevention shows a feeding female Anopheles funestus mosquito. The species is a known vector for malaria. The parasitic disease killed more than 620,000 people in 2020 and caused 241 million cases, mainly in children under 5 in Africa....
Malaria treatment is saving money while saving young lives

Credit: eClinicalMedicine (2022). DOI: 10.1016/j.eclinm.2022.101669 Young children in sub-Saharan Africa often become severely anemic as consequence of a malaria infection. Treating them requires blood transfusions and...
The brain can detect infection with malaria

Credit: Teresa Pais, 2022 A team of researchers from the Instituto Gulbenkian de Ciência (IGC) revealed that cells of the brain can detect the presence of malaria parasites in the blood,...
Monoclonal antibody prevents malaria in U.S. adults
One injection of a candidate monoclonal antibody (mAb) known as L9LS was found to be safe and highly protective in U.S. adults exposed to the malaria parasite, according to results from a National Institutes of Health Phase 1 clinical trial published in The New England Journal of Medicine. Additional clinical trials evaluating if L9LS can prevent malaria over six to 12...
Scientists identify promising transmission chain-breaker in the fight against malaria
by Johns Hopkins University Bloomberg School of Public Health Credit: CC0 Public Domain Blocking a key protein found in Anopheles gambiae mosquitoes—the principal vector for malaria transmission to humans in Africa—could thwart infection with malaria parasites and thus prevent them from transmitting the parasites to humans, according to a study from researchers at the Johns...
Unconventional T cells promote immunity to malaria
