Work description

The remnant mitochondrion (mitosome) of Trachipleistophora hominis. The short arrows define the border of the microsporidian, which is living inside a rabbit kidney cell, and the stars indicate the rabbit kidney cell mitochondria. The long arrow indicates the Trachipleistophora mitosome which reacts strongly with the specific antibody to the Trachipleistophora mitochondrial Hsp70. From Embley et al. 2003.
I carried out my PhD thesis at the National Institute of Agricultural Technology (INTA) and at the Institute of Biochemistry and Molecular Biology (Argentina). During that time I studied the pathology produced by the Epinotia aporema granulovirus (EpapGV) on its host Epinotia aporema, a major pest of soybean in Argentina. I also carried out the first molecular and functional study of a putative envelope-fusion protein of the Epinotia aporema granulovirus (Epap-F) involve in cell colonisation.

The main objective of my post-doctoral project, funded by a Marie Curie Fellowship, is to study the cellular evolution of microsporidia. These are microbial eukaryotes that are important obligate intracellular parasites of other eukaryotes including humans with HIV. My main focus is to determine the structure and functions of the microsporidian mitosome, a tiny remnant mitochondrion, including what it does and how it imports the proteins it needs.
