Binder et al., 'Development of Transient Peanut Allergy Following Lung Transplantation' (2011)

A transplanted lung carried a 12-year-old donor's peanut allergy for a year

A 47-year-old Canadian woman went into anaphylaxis over hospital breakfast cereal, tested positive to peanut and pine nut two months later, then lost the sensitivity entirely by twelve months. Donor immune cells are the suspect.
