Haploid gametes are generated through two consecutive meiotic divisions, with the segregation of chromosome pairs in meiosis I and sister chromatids in meiosis II. Separase-mediated stepwise removal of cohesion, first from chromosome arms and later from the centromere region, is a prerequisite for maintaining sister chromatids together until their(More)
Allergy to the short ragweed (Ambrosia artemisiifolia) pollen is a major health problem. The ragweed allergen repertoire has been recently expanded with the identification of Amb a 11, a new major allergen belonging to the cysteine protease family. To better characterize Amb a 11, a recombinant proform of the molecule with a preserved active site was(More)
O1 Two cell‐membrane peptidases carrying galactose‐alpha‐1,3‐galactose are implicated in delayed anaphylactic reactions upon pork kidney ingestion in patients with IgE‐antibodies to alpha‐Gal Christiane Hilger, Kyra Swiontek, Jörg Fischer, François Hentges, Chris‐ tiane Lehners, Martine Morisset, Bernadette Eberlein, Tilo Biedermann, Markus Ollert(More)
BACKGROUND Allergy to pollen from short ragweed (Ambrosia artemisiifolia) is a serious and expanding health problem in the United States and in Europe. OBJECTIVE We sought to investigate the presence of undescribed allergens in ragweed pollen. METHODS Ragweed pollen proteins were submitted to high-resolution gel electrophoresis and tested for IgE(More)
Pollen allergens from short ragweed (Ambrosia artemisiifolia) cause severe respiratory allergies in North America and Europe. To date, ten short ragweed pollen allergens belonging to eight protein families, including the recently discovered novel major allergen Amb a 11, have been recorded in the International Union of Immunological Societies (IUIS)(More)
BACKGROUND Allergy to short ragweed (Ambrosia artemisiifolia) pollen is a serious and expanding health problem in North America and Europe. Whereas only 10 short ragweed pollen allergens are officially recorded, patterns of IgE reactivity observed in ragweed allergic patients suggest that other allergens contribute to allergenicity. The objective of the(More)
