Trojan horse tactic gives parasites edge over immune systems

A study by researchers at the University of Edinburgh reveals that parasites can hide their genetic material inside 'vesicles' that mimic natural cellular functions, suppressing the immune response. This discovery could inform new strategies for treating diseases caused by parasitic worms, as well as allergies like hayfever.
