Peanut seeds are currently widely used as source of human food ingredients in the United States of America and in European countries due to their high quality protein and oil content. This article describes the classification and molecular biology of peanut seed allergens with particular reference to their cross-reactivities. Currently, the IUIS allergen nomenclature subcommittee accepts 12 pea...
Stereoselective and transannular reactivities are described for the ABD tricyclic manifold of phomactin A that possesses a unique structural topology.
The phenomenon of cross-reactivity between allergenic proteins plays an important role to understand how the immune system recognizes different antigen proteins. Allergen proteins are known to cross-react if their sequence comparison shows a high sequence identity which also implies that the proteins have a similar 3D fold. In such cases, linear sequence alignment methods are frequently used to...
different igg subclass profiles are produced in response to different antigenic stimuli in a variety of diseases. igg subclass levels may reflect disease severity. quantification of igg subclasses depends on the availability of specific monoclonal antibodies (mabs). in the present study seven hybridoma clones producing mabs reactive with multiple subclasses of human igg were established. spleno...
Telavancin is a semisynthetic lipoglycopeptide with a dual mechanism of action against Gram-positive pathogens. Two brief reports have suggested potential cross-reactivity of telavancin with the vancomycin particle-enhanced turbidometric immunoassay (PETIA). The purpose of this study was to evaluate several commercially available vancomycin immunoassays (fluorescence polarization [FPIA], enzyme...
Cross-reactivity of murine and recently human CD8(+) T cells between different viral peptides, i.e., heterologous immunity, has been well characterized. However, the directionality and quality of these cross-reactions is critical in determining their biological importance. Herein we analyzed the response of human CD8(+) T cells that recognize both a hepatitis C virus peptide (HCV-NS3) and a pep...
The cross-reactivity of mouse anti-benzylpenicilloyl antibodies against cephalothin-haptens and cephalothin-polymers was divergent depending on the source and isotype of antibodies and the methods to raise them. High cross-reactivity nearly equal to the reactivity to homologous haptens and polymers was obtained only with the IgE antibody of C57BL/6J mouse raised shortly after an immunizing inje...
The immunological phenomenon of cross-reactivity has consequences for the diagnosis and treatment of certain food allergies. Once allergy to a particular food has been confirmed, positive test results are often obtained against other foods and, although less frequently, true clinical cross-reactivity is determined. This article reviews the relevant clinical aspects of food allergies in which th...
