Abstract: The present invention provides nucleic acid sequences coding for the Cryptomeria japonica major pollen allergen Cry j I, Cry j II, Jun s I and Jun v I and fragments or peptides thereof. The present invention also provides purified Cry j I, Cry j II, Jun s I and Jun v I and at least one fragment thereof produced in a host cell transformed with a nucleic acid sequence coding for Cry j I, Cry j II, Jun s I and Jun v I or at least one fragment thereof, and fragments of Cry j I, Cry j II, Jun s I or Jun v I or at least one fragment thereof, and fragments of Cry j I, Cry j II, Jun s I or Jun v I prepared synthetically. Cry j I, Cry j II, Jun s I and Jun v I and fragments thereof are useful for diagnosing, treating, and preventing Japanese cedar pollinosis. The present invention also provides isolated peptides of Cry j I and Cry j II. Peptides within the scope of the invention comprise at least one T cell epitope, or preferably at least two T cell epitopes of Cry j I or Cry j II.

Abstract: A substantially pure, covalently linked human T cell reactive feline protein (TRFP) has been isolated from vacuum bag extract obtained by affinity purification of house dust collected from several homes with cats; DNA encoding all or a portion of the TRFP or peptide; compositions containing such a protein or peptide or portions thereof; and antibodies reactive with the TRFP or peptide are disclosed. Also disclosed are recombinant TRFP or peptide; modified or mutated TRFP peptides; their use for diagnostic or therapeutic purposes.

Abstract: The present invention provides isolated peptides of the major protein allergens of the genus Dermatophagoides. Peptides within the scope of the invention comprises at least one T cell epitope, or preferably at least two T cell epitopes of a protein allergen selected from the allergens Der p I, Der p II, Der f I, or Der f II. The invention also pertains to modified peptides having similar or enhanced therapeutic properties as the corresponding, naturally-occurring allergen or portion thereof, but having reduced side effects. The invention further provides nucleic acid sequences coding for peptides of the invention. Methods of treatment or of diagnosis of sensitivity to house dust mites in an individual and therapeutic compositions comprising one or more peptides of the invention are also provided.

Abstract: The present invention provides peptides having T cell stimulating activity termed recombitope peptides. Recombitope peptides of the invention preferably comprise at least two T cell epitopes derived from the same or from different protein antigens, and more preferably comprise at least two regions, each region preferably having human T cell stimulating activity and each region comprising at least one T cell epitope derived from a protein antigen. Recombitope peptides of the invention can be derived from protein allergens, autoantigens, or other protein antigens. The invention also provides methods of diagnosing sensitivity to a protein allergen or other protein antigen in an individual, methods to treat such sensitivity and therapeutic compositions comprising one or more recombitope peptides. The invention further provides methods for designing recombitope peptides of the invention where the protein antigen to which the individual is sensitive has unknown or ill-defined T cell epitopes.
