About the Project

Intestinal parasitic worm infections impose an enormous economic burden on society globally. Indeed the World Health Organisation has shown that parasitic worm infection is one of the most significant factors that traps developing countries into poverty. No effective vaccines exist to prevent infection of humans with gut-dwelling parasitic worms. Mice can be protected against infection with murine parasitic gut worms by vaccination. The project investigates mechanisms to optimise vaccine-induced resistance to the intestinal parasitic worm, Trichuris muris, and explores immunomodulatory antigens as vaccine candidates. Understanding vaccine-induced immunity in the mouse will inform the development of vaccines for use against these sorts of parasites in man. The project uses transgenic approaches and biomolecular analysis techniques, combined with a variety of contemporary immunological methodologies including cell and tissue culture, immunohistochemistry, flow cytometry, gene expression analyses and immunoassay.
