The findings open the door to test this new allergy treatment in «humanized mice» — micewith non-existent immune systems implanted with cells from a human immune system, for example, from a peanut - allergic person.
Now, researchers at the University of Michigan have found a way to retrain the immune system to ignore allergens by developing a nasal spray that vaccinates against peanutallergies, with promising results in mouse tests.
