Cyclophilins, a conserved protein family, have recently been proposed as candidate panallergens; however, their molecular, clinical, and functional roles remain largely undefined.<h4>Methods</h4>Within the Panallergens in Pediatrics (PAN-PED) cohort, we investigated 100 Italian children with seasonal allergic rhinitis (SAR) for IgE sensitization to the cyclophilins Bet v 7 and Ara h 18. This evidence concerns the gene PPIB and allergic rhinitis.
