Provided are peptide biomarkers for diagnosis of allergy, monitoring development of clinical tolerance in an allergic individual, and predicting whether an allergic subject is likely to develop clinical or natural tolerance over time. The invention also relates to diagnostic methods and diagnostic kits employing the peptide biomarkers.

Peptides, reagents and methods for detecting food allergy

The present invention relates to extracts of, and compounds isolated therefrom for use in modulating airway smooth muscle contractility. Methods of creating enriched extracts ofare disclosed, as are specific compounds isolated therefrom. Methods for the treatment of disorders involving airway smooth muscle, such as asthma, using the compounds and extracts described herein are also disclosed.

Compounds, extracts and methods from chinese medicinal herb sophora flavescens that inhibit airway contraction

The present invention provides methods and compositions for treating or preventing allergic responses, particularly anaphylactic allergic responses, in subjects who are allergic to allergens or susceptible to allergies. Methods of the present invention utilize administration of microorganisms to subjects, where the microorganisms produce allergens and protect the subjects from exposure to the allergens until phagocytosed by antigen-presenting cells. Particularly preferred microorganisms are gram-negative bacteria, gram-positive bacteria, and yeast. Particularly preferred allergens are proteins found in foods, venoms, drugs and latex that elicit allergic reactions and anaphylactic allergic reactions in individuals who are allergic to the proteins or are susceptible to allergies to the proteins. The proteins may also be modified to reduce the ability of the proteins to bind and crosslink IgE antibodies and thereby reduce the risk of eliciting anaphylaxis without affecting T-cell mediated Th1-type immunity.

Microbial delivery system

Methods for performing epitope mapping, and for characterizing the antibody binding affinity and epitope diversity of antibodies in a sample using peptide microarray are provided. In some aspects, methods are provided for the specific characterization of IgE and IgG4. Also disclosed are methods for diagnosing whether a milk-allergic individual will outgrow his or her allergy based on the characterization of the individual's milk allergen-specific IgE antibodies.

Methods for characterizing antibody binding affinity and epitope diversity in food allergy

The present invention provides methods and compositions for treating or preventing allergic reactions, particularly anaphylactic reactions. Methods of the present invention involve administering microorganisms to allergic subjects, where the microorganisms contain a recombinant version of the protein allergen. The recombinant version can be wild-type or may include mutations within IgE epitopes of the protein allergen. Preferably the compositions are administered rectally. Particularly preferred microorganisms are bacteria such as. Any allergen may be used in the inventive methods. Particularly preferred allergens are anaphylactic allergens including protein allergens found in foods, venoms, drugs and latex. The inventive compositions and methods are demonstrated in the treatment of peanut-induced anaphylaxis.

Methods and reagents for decreasing clinical reaction to allergy

The present invention is directed to methods for predicting or diagnosing a hazelnut-induced systemic reaction, and for methods for treating such a reaction.

Method for diagnosis and therapy of hazelnut-induced systemic reaction

It has been determined that allergens, which are characterized by both humoral (IgE) and cellular (T cell) binding sites, can be modified to be less allergenic by modifying the IgE binding sites. The IgE binding sites can be converted to non-IgE binding sites by masking the site with a compound that prevents IgE binding or by altering as little as a single amino acid within the protein, most typically a hydrophobic residue towards the center of the IgE-binding epitope, to eliminate IgE binding. The method allows the protein to be altered as minimally as possible, other than-within the IgE-binding sites, while retaining the ability of the protein to activate T cells, and, in some embodiments by not significantly altering or decreasing IgG binding capacity The examples use peanut allergens to demonstrate alteration of IgE binding sites. The critical amino acids within each of the IgE binding epitopes of the peanut protein that are important to immunoglobulin binding have been determined. Substitution of even a single amino acid within each of the epitopes led to loss of IgE binding. Although the epitopes shared no common amino acid sequence motif, the hydrophobic residues located in the center of the epitope appeared to be most critical to IgE binding.

The present invention provides herbal formulas, and compositions thereof, that can treat or reduce the severity, intensity, or duration of asthma and asthma-related symptoms. The compositions may optionally include one or more adjuvants, cytokines, encapsulating materials, or pharmaceutically acceptable carriers or excipients, and may be administered prior to, during, or after the development of asthmatic symptoms in a patient in need thereof.

Nucleic acids encoding ara h 3 polypeptides

Modified proteins are disclosed that maintain enzymatic and insecticidal activity while displaying reduced or eliminated allergenicity. Epitopes which bind to anti-patatin antibodies were identified, and removed via site directed mutagenesis. Tyrosines were observed to generally contribute to the allergenic properties of patatin proteins. Removal of glycosylation sites was observed to reduce or eliminate antibody binding. Permuteins are also disclosed which have a rearranged amino acid sequence while retaining enzymatic activity. Deallergenized proteins and permuteins can be used as insecticidal materials, as nutritional supplements, and as immunotherapeutic agents.
