About

I obtained my PhD in 2011 at University of Valencia (Spain) with high honours under the supervision of Dr. Rafael Toledo and J. Guillermo Esteban. My interests during my PhD were the host-parasite interactions at a proteomics and immunological level in the Echinostoma-rodent. In 2012 I was appointed as a Postdoctoral Research Fellow at James Cook University at the laboratory of Alex Loukas.

My research focus is the analysis of the proteomes and secretomes of parasites and how they orchestrate a parasitic existence. I am also interested in the host-parasite relationships, with a particular emphasis on soil-transmitted helminths (e.g. hookworms, whipworms, roundworms) and water-borne trematodes such as Schistosoma spp. I have described the excretory-secretory proteins of different helminths and have been involved in in analyses of large-scale sequence datasets generated from a range of parasites (i.e. transcriptomes). I recently focused my attention to study small-secreted parasitic vesicles (exosomes) and their implication in parasite-host communication and the modulation of the host’s immune response.

Carcinogenic liver fluke infection: Gene editing- and vaccination-mediated approaches to interrupt host-parasite communication

Indicative Funding: $825,674 over 5 years (administered by George Washington University)
Summary: Long term infection with liver fluke - a food-borne parasitic worm - leads to cholangiocarcinoma (CCA), a form of liver cancer with a dismal prognosis. Previously we identified proteins and vesicles from these parasites that may cause this cancer. This new project will investigate the roles of these parasite proteins and vesicles in cancer, which may lead to new treatments and control for fluke infection and CCA

Secreted exosome-like vesicles from the carcinogenic liver fluke

Indicative Funding: $742,660 over 4 years
Summary: Parasitic worms secrete molecules from their oral openings and outer surfaces as they feed and reproduce inside their human hosts. These molecules are referred to as Excretory/Secretory (ES) products, akin to our saliva and sweat. These ES products represent the molecular interface of the host-parasite relationship. We recently showed that ES products from the parasitic liver fluke, a worm that is a major cause of liver cancer throughout parts of SE Asia, are taken up by cells lining the human bile ducts, the site where the parasite resides for years at a time. Until now the mechanisms by which these molecules are taken up and internalised by host cells was unknown. We now show that liver fluke ES proteins enter into human bile duct cells by forming small cell-like vesicles called exosomes. Once the flukes exosomes get inside human bile duct cells they induce a series of changes inside the cell which typifies the early stages of cancer formation. We now propose to better characterise the process of exosome uptake by human bile duct cells and exploit this information to discover vaccines to combat this carcinogenic infection and develop new tools to identify people who are most at risk of developing cancer from liver fluke infection.
