The allergenic potential of enolases: physiological and pathophysiological insights.

Abstract

Purpose of review: This review gives an overview on the current knowledge of the physiological and pathophysiological features of enolases and how these features might contribute to the enzymes' allergenic properties. It summarizes the most recent literature on allergenic enolases and raises questions that need to be answered in the future to gain a better understanding of the role of enolases in allergic diseases.

Recent findings: The recent identification of two novel allergenic enolases, from London plane tree and whiff, further supports the uniqueness of this allergen family: the occurrence of enolases in the three major kingdoms of life and the capability to induce allergic symptoms via inhalation, ingestion, and skin contact.

Summary: The importance and uniqueness of enolases as allergenic molecules is widely accepted. However, studies linking the biochemical and physiological features of enolases with their potential to induce allergies are still needed. This would contribute to a better understanding about the role of enolases in the induction of allergic diseases, to improve specificity and sensitivity of allergy diagnosis and to further enable the development of patient-tailored prophylactic and therapeutic approaches.
