Main research lines of the Nanomalaria group:

• Definition of polymeric nanocarriers which combine into a single chemical structure drug encapsulating capacity, antiplasmodial activity, specific targeting to Plasmodium-infected red blood cells (pRBCs), and affordable synthesis cost. This line of research is currently being adapted to develop new nanomedicines for leishmaniasis.
• Application of heparin as a dual agent with antimalarial and nanovector targeting activities toward pRBCs.
• Targeting Plasmodium stages in the mosquito vector, which will bypass long and costly clinical trials that often delay or prevent the development of nanomedicines for malaria.
• Use of red blood cells (RBCs) as antimalarial carriers, an innovative strategy that confronts Plasmodium with drugs at the moment of erythrocyte infection by the pathogen. Using this approach that provided excellent in vivo results where malaria-infected mice were freed of parasites and cured, we have developed new immunoliposomes carrying drug combinations for their targeted delivery to RBCs and gametocytes, the transmission stage shared between humans and the Anopheles mosquito vector which is a preferred target of malaria eradication efforts.
• Development of DNA aptamers as new malaria diagnostic agents.
• Identification, cloning and characterization of the proteins mediating vesicular transport in Plasmodium, using nanotechnological femtoinjection techniques in giant unilamellar vesicles.
• Discovery of functional protein aggregation in live Plasmodium and Leishmania parasites, and of a new family of drugs targeting this process.
