Cyclophilins and gibberellin-regulated proteins in IgE-mediated allergic diseases

Abstract

The prevalence of immunoglobulin E (IgE)-mediated allergic diseases is currently experiencing an epidemic trend characterized by an increase in both the number of affected individuals and the proportion of patients with multiple sensitizations. The majority of these multiple sensitizations are attributed to IgE reactions to genuine allergenic proteins from unrelated species. However, there is a growing trend of patients becoming sensitized to highly cross-reactive molecules, such as profilins, polcalcins, lipocalins, serum albumins, tropomyosins, and non-specific lipid transfer proteins (nsLTPs). In addition, allergen families that were previously considered of minimal importance are now gaining recognition for their role in the pathogenesis of IgE-mediated allergic diseases. Consequently, these allergen families are increasingly being considered in the diagnostic process. In this review, we aim to provide a comprehensive summary of the biochemical and allergological information about two of these “new” allergen families: cyclophilins (Cyp) and gibberellin-regulated proteins (GRP).
