Our Team

In 1996 she received a Ph.D. in Biological Sciences from the Univ. of Granada. Later, she moved to Brazil (Univ. of Sao Paulo), where she did her first post-doctotal training, working on biological aspects of Plasmodium vivax. In 1998,she joined the ZMBH (Heidelberg) where she did her second postdoctoral stay working with Toxoplasma gondii. In 2000, she moved back to the Univ. of Sao Paulo as a Research Associated Fellow to continue her studies on P. vivax. In 2007, she joined ISGlobal's research centre in the program of malaria.

Lines of research

• Function and localization of variant proteins in P. vivax. In the absence of an effective continuous in vitro culture system for blood stages and reverse genetics, functional gene discovery in P. vivax is presently undoable. They explore the use of heterologous transfection of Vir proteins in P. falciparum to determine vir function.
• Antigen discovery for vaccine development in P. vivax malaria. The interest lies in identifying new antigens exported to the surface of infected reticulocytes through tolerization and subsequent immunizations with P. vivax infected reticulocytes. The aim is to determine which antigen(s) correlate with acquired immunity and clinical protection for furthering vaccine development against this parasite.
• Establishment of a continuous culture system for blood stages of P. vivax. Recently, the use of hematopoietic stem cells and addition of specific factors, which drove their differentiation into reticulocytes, represented a major improvement as it provided a constant source of reticulocytes, albeit in low percentages, to develop a continuous culture system. Using this information, they try to establish a continuous P. vivax culture system by immortalizing nucleated human hematopoietic stem cells.
