Immunological Cross-Reactivity of the Major Allergen from Perennial Ryegrass (Lolium perenne), Lol p I, and the Cysteine Proteinase, Bromelain Academic Article uri icon

abstract

  • Antibodies prepared in rabbits against the major allergen from ryegrass (Lolium perenne), Lol p I, cross-reacted with the cysteine proteinase bromelain from pineapple and vice versa. Deglycosylation of the proteins showed that the cross-reaction was based on recognition of the carbohydrate moiety of the allergen, but for bromelain the cross-reaction was most likely due to a combination of factors. The results indicate that the carbohydrate residues from these allergens play an important role in cross-reactions found between them and possibly those from other species.
