Purpose of reviewPFAS shows various cross-reactivities with antigens because of the area in which the patient resides and dietary habits, and progress in component allergen analysis in recent years has clarified the pathogenesis. This review describes newly identified findings for antigens involved in PFAS.Recent findingsWe describe recent findings for PR-10 family, profilin and LTP, as known major antigens for PFAS. Microarrays of allergen components have significantly improved the ability to describe IgE profiles. In addition, we describe a new antigen, GRP, in the fruit pulp of recently identified fruit.SummaryPFAS is a food allergy based on the cross-reactivity of pollen antigens and food antigens. Symptoms induced by sensitization differ depending on the specific antigen. The functions of each antigen are diverse, and even the same antigen can cause different symptoms. As analytical techniques progress, the findings will help to establish treatments, such as specific immunotherapy.
