Writing in Cell Reports, researchers from the National Institute of Allergy and Infectious Diseases (NIAID) and collaborators have presented a multifaceted analysis and structure-function study of a panel of human monoclonal antibodies (hmAbs) targeting AMA1 elicited by natural Plasmodium falciparum infection in a malaria-endemic region in Mali.
Two simultaneous but independent studies published in Science identified, by introducing mutants into its genome, the essential and nonessential genes of Plasmodium knowlesi, one of the malaria parasites related to the dreaded Plasmodium vivax. Their results could help in the development and prioritization of antimalarial strategies.
Malaria remains a significant global health challenge, causing over 600,000 deaths annually despite existing prevention and treatment measures. Current vaccines and monoclonal antibodies (mAbs) against Plasmodium falciparum, such as RTS,S/AS01 and R21, primarily target the central repeat region of the circumsporozoite protein (CSP) but have shown limited efficacy in completely preventing infection.
Malaria is caused by Plasmodium species that infect hundreds of millions of people annually. Among the plasmodia, Plasmodium falciparum is considered the most dangerous due to frequent severe clinical complications and high mortality rates. Researchers from the University of California at Riverside described the discovery and mechanism of action of MED-6189, a kalihinol analog effective against drug-sensitive and drug-resistant P. falciparum strains in vitro and in vivo.
Noul Co. Ltd.’s Micro-Intelligent Laboratory, an artificial intelligence-powered diagnostic system, demonstrated superiority over microscopic diagnosis for malaria in a study presented at the 2024 International Congress for Tropical Medicine and Malaria.
The increasing resistance to intravenous artemisinin therapy for malaria highlights the urgent need for new treatments that offer better patient compliance and a single-dose cure to address this global health threat. Novartis AG recently presented the discovery, development and evaluation of aminoisoquinolines as fast-acting intravenous therapeutic agents for severe malaria treatment.
Novel antimalarials are urgently needed to face the challenge of increasing parasite resistance. The isoprenoid precursor biosynthesis pathway is an attractive target for developing novel antimalarial drugs, being an essential and specific pathway in apicomplexan parasites.
