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.

Human T cell reactive feline protein (TRFP) isolated from house dust and uses therefor

The present invention provides isolated peptides of the major protein allergens of the genus. 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.

T cell epitopes of the major allergens from dermatophagoides (house dust mite)

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.

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.

Hapten-carrier conjugates capable of eliciting anti-hapten antibodies in vivo are disclosed. Methods of preparing the hapten-carrier conjugates and therapeutic compositions are also disclosed. Where the hapten is a drug of abuse, a therapeutic composition containing the hapten-carrier conjugate is particularly useful in the treatment of drug addiction, more particularly, cocaine addiction. Passive immunization using antibodies raised against conjugates of the instant invention is also disclosed. The therapeutic composition is suitable for co-therapy with other conventional drugs.

Hapten-carrier conjugates capable of eliciting anti hapten antibodies in vivo by administering, in a therapeutic composition, are disclosed. Anti-hapten antibodies elicited compete with free hapten upon subsequent challenge of a vaccinated individual. Methods of preparing said conjugates and therapeutic compositions are also disclosed. Where the hapten is a drug of abuse, a therapeutic composition containing the hapten-carrier conjugate is particularly useful in the treatment of drug addiction, more particularly, cocaine addiction. Passive immunization using antibodies raised against conjugates of the instant invention is also disclosed. The therapeutic composition is suitable for co-therapy with other conventional drugs.
