Api g 5 is a glycoprotein belonging to a family of flavin adenine dinucleotide FAD -containing oxidases Bublin et al. Note that the Api g 5 partial sequence so far available does not seem to be homologous with Art v 1 which is much smaller and has a defensin like and a hydroxyproline-rich domain Himly et al. However, it is possible that the complete sequence might reveal additional Art v 1 like domains.
Ganglberger et al. Marknell DeWitt et al [ ] have reported that these sequences are homologous to the sequence of the timothy grass pollen allergen Phl p 4. Heiss et al. Deglycosylation reduces the observed mass by 12 kDa and removes IgE binding. Skip to main content Skip to navigation Skip to Search.
Celery spice is used in many processed foods such as spice mixtures, soups, broths and salad dressings. More information.. Allergy Information: Allergy to celery is associated with allergy to birch pollen and also allergy to mugwort pollen. Supplementary information on Celery Allergy Allergy to celery tuber celeriac , a member of the Apiaceae family, belongs to the most frequent pollen-related food allergies in some European countries such as Switzerland, France, or Germany.
Symptoms Local reactions in the mouth such as itching, but also systemic reactions affecting the skin, the nose and lungs and the stomach or severe life threatening reactions anaphylaxis have been observed upon ingestion of celery. How much is too much? Related foods cross reactivity Allergy to celery is frequently associated with birch and or mugwort pollinosis. Who, when, how long, and how often? Diagnosis For diagnosis skin testing with celery extract may be performed, or blood samples may be measured.
Protocol: controls, definition of positive etc Histamine was the positive control in Stricker et al. Number of Patients: Stricker et al. Summary of Results: Stricker et al. All 12 French patients gave positive SPT to mugwort. EAST was used by Jankiewicz et al. Immunoblotting Immunoblotting separation: Bublin et al [ ], Hoffmann-Sommergruber et al.
Immunoblotting detection method: Bublin et al [ ] blotted proteins onto nitrocellulose membranes Protran BA 85, Schleicher and Schuell, Dassel, Germany. Immunoblotting results: Bublin et al [ ] report that IgE from pooled sera bound to a range of allergens in celery extract with a dominant pair at 53 and 57 kDa.
Patients were first required to keep the drink either placebo or active drink in their mouths for 1 minute and to spit it out. The amount of drink doubled every 15 minutes, starting with 5 mls 0. If there had been no response, the other drink was used. If there were no symptoms from the spit phase, 13, 26, 52 and mls of the drinks were swallowed up to Blind: Double blind followed by open if negative Ballmer-Weber et al.
Number of Patients: 32 Ballmer-Weber et al. Symptoms: Ballmer-Weber et al. Biochemical Information for Api g 1 Api g 1. P 3D Structure Accession No. Allergen stability: Process, chemical, enzymatic: Jankiewicz et al. Nature of main cross-reacting proteins: As a consequence of sequence homology there are cross-reaction with major food allergens from apple Mal d 1 , carrot Dau c 1 and cherry Pru a 1 and with pollen allergens from the order Fagales Bet v 1, Aln g 1, Cor a 1, Car b 1.
Api g 1 is also cross-reactive with the birch pollen allergen Bet v 1 and related proteins from carrot, cherry, apple as studied by immunoblot, and immunoblot inhibition Ebner et al [ 46 ].
Its precise function is not known but it may be a steroid binding protein as is Bet v 1 Markovic-Housley et al. Allergen purification: Hoffmann-Sommergruber et al. J Allergy Clin Immunol.
