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...
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....

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...

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...
