Extracellular vesicles from parasitic helminths contain specific excretory/secretory proteins and are internalized in intestinal host cells.
2012
The study of host-parasite interactions has increased considerably in the last decades, with many studies focusing on the identification of parasite molecules (i.e. surface or excretory/secretory proteins (ESP)) as potential targets for new specific treatments and/or diagnostic tools. In parallel, in the last few years there have been significant advances in the field of extracellular vesicles research. Among these vesicles, exosomes of endocytic origin, with a characteristic size ranging from 30-100 nm, carry several atypical secreted proteins in different organisms, including parasitic protozoa. Here, we present experimental evidence for the existence of exosome-like vesicles in parasitic…
Isolation and Analysis of Fasciola hepatica Extracellular Vesicles
2020
The finding of extracellular vesicles (EVs) as important players in parasite-parasite and host-parasite communications has led to an increasing number of reports in the literature. Different protocols have been developed for isolation and further characterization of EVs from parasitic helminths. In this chapter, we describe step by step procedures to isolate EVs secreted by Fasciola hepatica adults in culture, which could be also applied for other developmental stages of the parasite, as well as EVs present in plasma and urine. Along with classical isolation methods like differential ultracentrifugation, and more recent techniques like size exclusion chromatography (SEC), here we also refer…
