Peanut allergens can trigger a potent and sometimes dangerous immune response in
an increasing number of people. The molecular structures of these allergens form
the basis for understanding this response. This review describes the currently
known peanut allergen structures and discusses how modifications both enzymatic
and non-enzymatic affect digestion, innate immune recognition, and IgE
interactions. The allergen structures help explain cross-reactivity among
allergens from different sources, which is useful in improving patient
diagnostics. Surprisingly, it was recently noted that similar short peptide
sequences among unrelated peanut allergens could also be a source of
cross-reactivity. The molecular features of peanut allergens continue to inform
predictions and provide new research directions in the study of allergic disease.
