Trichuris trichiura egg extract proteome reveals potential diagnostic targets and immunomodulators.
2021
The proteomic analysis was performed at the proteomics facility of SCSIE, University of Valencia (Burjassot, Spain) that belongs to ProteoRed, PRB2-ISCIII, Madrid, Spain. We also thank Dr. Tatiana Corey, Dr. Amy Beierschmitt and Dr. Pompei Bolfa for their support during sample collection.
Echinostomes: genomics and proteomics
2008
Echinostomes are excellent models to study host-parasite interactions in intestinal helminthiases. In this chapter, data available from genomic and proteomic studies are analyzed in detail to indicate advantages and pitfalls in the research using these organisms. The lack of a genome sequence project and the low number of sequences deposited in the databases not only affect the genomic studies but also debilitate proteomic findings since in most cases, although good spectrometric data can be obtained, the available database often fail to identify the protein from the peptides obtained.
Host manipulation of a freshwater crustacean (Gammarus roeseli) by an acanthocephalan parasite (Polymorphus minutus) in a biological invasion context.
2006
8 pages; International audience; Several gammarid species serve as intermediate hosts for the acanthocephalan parasite Polymorphus minutus. This parasite influences gammarid behaviour in order to favour transmission to its ultimate host, generally a bird. We investigated this host manipulation in Gammarus roeseli, a gammarid species introduced in France 150 years ago which now coexists with several exotic species from different origins. In the field, vertical distribution of G. roeseli revealed a higher proportion of infected individuals close to the water's surface and the size distribution of infected gammarids revealed predation pressure on infected individuals. However, under laboratory…
Anaphylaxis caused by helminths: review of the literature.
2012
BACKGROUND: Anaphylaxis is a severe, life-threatening, generalized or systemic hypersensitivity reaction. In many individuals with anaphylaxis a pivotal role is played by IgE and the high-affinity IgE receptor on mast cells or basophils. Less commonly, it is triggered through other immunologic mechanisms, or through nonimmunologic mechanisms. The human immune response to helminth infections is associated with elevated levels of IgE, tissue eosinophilia and mastocytosis, and the presence of CD4+ T cells that preferentially produce IL-4, IL-5, and IL-13. Individuals exposed to helminth infections may have allergic inflammatory responses to parasites and parasite antigens. AIM: To summarize th…
