摘要:
The present invention relates to fluorocarbon vectors for the delivery of influenza antigens to immunoresponsive target cells. It further relates to fluorocarbon vector-influenza antigen constructs and the use of such vectors associated with antigens as vaccines and immunotherapeutics in animals, including humans.
摘要:
The present invention relates generally to an immunogenic LHRH composition and more particularly to an immunogenic LHRH composition comprising a LHRH C-terminal fragment of at least five amino acids. The present invention is useful, inter alia, as a prophylactic and/or therapeutic agent for the modification of fertility and behaviour patterns of animals, the achievement of livestock production gains such as increasing growth, decreasing feed conversion ratios or the control of unwanted organoleptic characteristics or the treatment of disorders of the reproductive organs.
摘要:
The present invention relates to methods for purifying immunogenic, prophylactically and therapeutically effective complexes of modified heat shock proteins noncovalently associated with antigenic peptides of cancer or infected cells. The claimed methods comprise the constructing of a nucleotide sequence encoding a secretable modified heat shock protein, expressing the sequence in an appropriate host cell, recovering the immunogenic complexes from the cell culture and the cells, and purifying the immunogenic complexes by affinity chromatography. Large amounts of such immunogenic complexes can be obtained by large-scale culturing of host cells containing the genetic sequence. The complexes can be used as a vaccine to elicit specific immune responses against cancer or infected cells, and to treat or prevent cancer or infectious diseases.
摘要:
The present invention relates to a vaccine for increasing the immunogenicity of a tumor antigen thus allowing treatment of cancer, as well as a vaccine that increases the immunogenicity of a viral antigen, thus allowing treatment of viral infection, including immunodeficiency virus (HIV) infection. In particular, the present invention provides a fusion protein comprising a defensin fused to either a tumor antigen or viral antigen which is administered as either a protein or nucleic acid vaccine to elicit an immune response effective in treating cancer or effective in treating or preventing viral infection.
摘要:
Diphtheria toxin polypeptides comprising a mutant R binding domain exhibit reduced target cell binding and may be used as vaccines to immunize a mammal against infection by Corynebacterium diphtheria.
摘要:
A vaccine capable of protecting a recipient from infection caused by group B Streptococcus. The vaccine provides polysaccharide-protein moieties and contain (a) a group B Streptococcus polysaccharide conjugated to (b) a functional derivative of a group B Streptococcus C protein alpha antigen that retains the ability to elicit protective antibodies against group B Streptococcus. The vaccine may contain only one type of such polysaccharide-protein unit or may contain a mixture of more than one type of unit.
摘要:
This invention relates to antigenic conjugate molecules comprising the capsular polysaccharide of Group B streptococcus type II which are covalently linked to protein. This invention also relates to vaccines and methods of immunizing mammals, including humans against infection by Group B streptococcus type II (GBS II). Multivalent vaccines comprising the conjugate molecules of this invention and antigens to other pathogenic bacteria are also claimed.
摘要:
Immunoassays of psychoactive drugs including psychotomimetic drugs, narcotic drugs, and tetrahydrocannabinols and treatment methods based on the antigenic properties of protein conjugates of these drugs. These methods are based upon treating the psychoactive substances as haptens and utilizing their protein conjugates to produce antibodies to the psychoactive materials themselves. The immunoassay methods include both agglutination and agglutination-inhibition reactions. The treatment methods include treatment or both exogenous, administered drugs (such as cannabinols, LSD, heroin and morphine) and endogenous substances (such as N,N-Dimethyltryptamine and 5-Methoxy-N,N-Dimethyltryptamine, by active immunization and also passive immunization.
摘要:
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 the 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.
