Journal ArticleDOI
Predictive value of skin prick tests using recombinant allergens for diagnosis of peanut allergy.
C. Astier,Martine Morisset,O. Roitel,F. Codreanu,Sandrine Jacquenet,P Franck,Virginie Ogier,N. Petit,Barbara Proust,Denise-Anne Moneret-Vautrin,A. Wesley Burks,Bernard Bihain,Hugh A. Sampson,Gisèle Kanny +13 more
TL;DR: Skin prick tests to individual recombinant peanut allergens appear to be a safe and effective diagnostic tool and monosensitization to rAra h 2 and rArah 1 and/or rARA h 3 is predictive of more severe reactions.
Journal ArticleDOI
A Novel Immunoassay Using Recombinant Allergens Simplifies Peanut Allergy Diagnosis
F. Codreanu,Olivier Collignon,O. Roitel,B. Thouvenot,C. Sauvage,A.-C. Vilain,M.-O. Cousin,A. Decoster,J M Renaudin,C. Astier,Jean-Marie Monnez,Pierre Vallois,Martine Morisset,D.A. Moneret-Vautrin,Marie Brulliard,Virginie Ogier,M.-C. Castelain,Gisèle Kanny,Bernard Bihain,Sandrine Jacquenet +19 more
TL;DR: A simple blood test can be used to diagnose peanut allergy with a high level of precision, and Double-blind placebo-controlled food challenge will remain useful for the few cases where immunological and clinical observations yield conflicting results.
Journal ArticleDOI
A single oral sensitization to peanut without adjuvant leads to anaphylaxis in mice.
Barbara Proust,C. Astier,Sandrine Jacquenet,Virginie Ogier,Erwan Magueur,O. Roitel,Christelle Belcourt,Martine Morisset,D.A. Moneret-Vautrin,Bernard Bihain,Gisèle Kanny +10 more
TL;DR: A model of severe peanut hypersensitivity within 2 weeks following single oral exposure without adjuvant is obtained, which may be useful for further basic and applied studies on peanut allergy.
Journal ArticleDOI
Nonrandom variations in human cancer ESTs indicate that mRNA heterogeneity increases during carcinogenesis
Marie Brulliard,Dalia Lorphelin,Olivier Collignon,Walter Lorphelin,Benoit Thouvenot,Emmanuel Gothié,Sandrine Jacquenet,Virginie Ogier,O. Roitel,Jean-Marie Monnez,Pierre Vallois,Frances T. Yen,Olivier Poch,Marc Guenneugues,Gilles Karcher,Pierre Oudet,Bernard Bihain +16 more
TL;DR: It is shown that cancer ESTs have greater variations than normal ESTs for >70% of the tested genes, and a working hypothesis is developed thatcancer EST heterogeneity results primarily from increased transcription infidelity.
Journal ArticleDOI
Detection of IgE‐reactive proteins in hydrolysed dog foods
O. Roitel,Lionel Bonnard,Alexandre Stella,Odile Schiltz,Delphine Maurice,Gaël Douchin,Sandrine Jacquenet,Claude Favrot,Bernard Bihain,Nicolas Couturier +9 more
TL;DR: Some commercial hydrolysed diets contain carbohydrate proteins that some dogs have circulating IgE antibodies targeting these proteins, and these findings are unknown.
