During a collaborative visit to Stanford Medical School, Dr Melanie Neeland used an advanced immune profiling tool to understand why some children develop harmful allergic reactions to peanuts, while others are primed to become allergic but can eat peanut without adverse reactions.

Using just a teaspoon of blood from kids in the ongoing Health Nuts study, Dr Neeland says the research could one day help distinguish which children might remain tolerant to peanuts from those who will develop clinical allergy.

This would allow doctors to begin treatment early and prevent life-threatening allergic reactions.

The research was published in Nature Communications https://dx.doi.org/10.1038/s41467-020-14919-4
