BACKGROUND We recently cloned and described a vicilin and showed it to be a major cashew allergen. Additional IgE-reactive cashew peptides of the legumin group and 2S albumin families have also been reported. Here, we attempt to clone, express and characterize a second major cashew allergen. METHODS A cashew cDNA library was screened with human IgE and(More)
Allergic reactions to tree nuts can be serious and life threatening. Considerable research has been conducted in recent years in an attempt to characterize those allergens that are most responsible for allergy sensitization and triggering. Both native and recombinant nut allergens have been identified and characterized and, for some, the IgE-reactive(More)
The ubiquitous presence of allergens in the human food supply coupled with increased awareness of food allergies warrants undertaking appropriate preventive measures to protect sensitive consumers from unwanted exposure to offending food allergens. Attempts to reduce or eliminate food allergenicity through food processing have met with mixed results. The(More)
BACKGROUND Cashew nut allergy is the second most commonly reported tree nut allergy in the United States. We have previously cloned and characterized major cashew allergens belonging to the vicilin and legumin families of seed storage proteins. OBJECTIVE Here we set out to describe a third major cashew allergen, a 2S albumin. METHODS The recombinant(More)
Background Patients allergic to cashew nuts often report allergy to pistachio, which could be a result of cross-reactivity between the two as both are members of the Anacardiaceae family. Objective Because cashew 7S globulin (vicilin, Ana o 1) is a recognized major allergen, we cloned the pistachio homologue and assayed it for IgE reactivity and(More)
BACKGROUND Food allergy is estimated to affect 3-4% of adults in the US, but there are limited educational resources for primary care physicians. The goal of this study was to develop and pilot a food allergy educational resource based upon a needs survey of non-allergist healthcare providers. METHODS A survey was undertaken to identify educational needs(More)
Almond major protein (AMP or amandin), the primary storage protein in almonds, is the major allergen recognized by almond-allergic patients. A rabbit antibody-based inhibition ELISA assay for detecting and quantifying AMP in commercial foods has been developed, and this assay, in conjunction with Western blotting analyses, has been applied to the(More)
Since the original description of X-linked agammaglobulinemia in 1952, the number of independent primary immunodeficiency diseases (PIDs) has expanded to more than 100 entities. By definition, a PID is a genetically determined disorder resulting in enhanced susceptibility to infectious disease. Despite the heritable nature of these diseases, some PIDs are(More)
Allergic reactions to walnuts and hazelnuts can be serious. The 11S globulins (legumins) have been identified as important allergens in these and other nuts and seeds. Here we identify the linear IgE-binding epitopes of walnut and hazelnut 11S globulins, and generate 3D 11S globulin models to map the locations of the epitopes for comparison to other(More)
Anaphylaxis is a source of anxiety for patients and healthcare providers. It is a medical emergency that presents with a broad array of symptoms and signs, many of which can be deceptively similar to other diseases such as myocardial infarction, asthma, or panic attacks. In addition to these diagnostic challenges, anaphylaxis presents management(More)
