摘要:
The present invention relates to a combination therapy method for treating gastrin-dependent tumors. The method comprises the immunization of a patient with an anti-gastrin 17 immunogenic composition in combination with the administration of chemotherapeutic agents such as 5-fluorouracil and leucovorin.
摘要:
The present invention provides progastrin-binding molecules specific for progastrin that do not bind gastrin-17(G17), gastrin-34(G34), glycine-extended gastrin-17(G17-Gly), or glycine-extended gastrin-34(G34-Gly). Further, the invention provides monoclonal antibodies (MAbs) selective for sequences at the N-terminus and the C-terminus of the gastrin precursor molecule, progastrin and the hybridomas that produce these MAbs. Also provided are panels of MAbs useful for the detection and quantitation of progastrin and gastrin hormone species in immuno-detection and quantitation assays. These assays are useful for diagnosing and monitoring a gastrin-promoted disease or condition, or for monitoring the progress of a course of therapy. The invention further provides solid phase assays including immunohistochemical (IHC) and immunofluorescence (IF) assays suitable for detection and visualization of gastrin species in solid samples, such as biopsy samples or tissue slices. The progastrin-binding molecules are useful therapeutically for passive immunization against progastrin in progastrin-promoted diseases or conditions. Also provided are surrogate reference standard (SRS) molecules that are peptide chains of from about 10 to about 35 amino acids, wherein the SRS molecule comprises at least two epitopes found in a protein of interest of greater than about 50 amino acids. Such SRS molecules are useful as standards in place of authentic proteins of interest.
摘要:
Chimeric peptide epitopes can serve as effective immunogens against hormones and other small peptides or proteins. Immunogenic peptides are selected from promiscuous helper T-lymphocyte epitopes and synthesized together with self antigenic peptide sequences optionally fused through a spacer moiety. Examples of the chimeric peptide immunogens of the invention include peptide sequences which may be from any antigen, such as a gonadotropin releasing hormone (GnRH), linked with an immunogenic peptide sequence such as a promiscuous helper T-lymphocyte epitope of measles virus protein F, tetanus toxoid, or malaria protein CSP. Compositions of the chimeric immunogen are found effective in eliciting high and specific anti-GnRH antibody titers. This invention also relates to compositions and methods for synergistically enhancing or suppressing an immune response to a target antigen.

Chimeric peptide epitopes can serve as effective immunogens against hormones and other small peptides or proteins. Thus, immunogenic peptides are selected from promiscuous Th epitopes and synthesized together with self antigenic peptide sequences fused with or without end to end spacer peptide interconnections. A peptide sequence which may be of the gonadotropin releasing hormone is linked with an immunogenic peptide sequence selected from a promiscuous Th-epitope of measles virus protein F, tetanus toxoid, or malaria protein CSP. Compositions of the chimeric immunogen are found effective in eliciting high and specific anti-GnRH antibody titers.
摘要:
The invention concerns immunogens, immunogenic compositions and method for the treatment of gastrin-dependent tumors. The immunogens comprise a peptide from the CCK-B/gastrin-receptor conjugated to a spacer and to an immunogenic carrier. The immunogens are capable of inducing antibodies in vivo which bind to the CCK-B/gastrin-receptor in tumor cells, thereby preventing growth stimulating peptide hormones from binding to the receptors, and inhibiting tumor cell growth. The immunogens also comprise antibodies against the CCK-B/gastrin-receptor for passive immunization. The invention also concerns diagnostic methods for detecting gastrin-dependent tumors in vivo or from a tissue biopsy using the antibodies of the invention.

摘要:
This invention relates to a method for contraception comprising the active immunization of a female mammal against zona pellucida using a composition comprising an effective amount of anti-idiotypic antibodies formed against anti-zona pellucida antibodies, which anti-idiotypic antibodies express internal images of zona pellucida antigenic determinants capable of eliciting a contraceptive response.
摘要:
A safe and effective vaccine to prevent, slow, halt or reverse progression of Alzheimer's disease in human patients is disclosed. The vaccine includes Aβ1-42 or an beta amyloid self epitope (e.g. Aβ1-15, or other 7-mer or 15-mer peptide epitopes derived from Aβ1-42) conjugated to an immunogenic carrier (e.g. DT) formulated in a water-in-oil Th2-biased adjuvant/delivery system.
摘要:
The invention provides assay methods for the detection and quantitation of gastrin hormones, including total and free gastrin hormone in a sample. ELISA-type heterogeneous phase assays suitable for use with biological fluid samples such as blood, plasma or other bodily fluids of a mammal, particularly a human subject are provided. The method provides a precise assay for the amounts of free and total G17 and G34 in biological fluid samples, as well as the amounts of free and total Gly-extended G17, and Gly-extended G34. Also provided are methods of determining suitable treatment for patient suffering from a gastrin hormone-mediated disease or condition employing gastrin hormone immunoassays.
摘要:
The invention relates to the treatment and/or prevention of cancerous and/or, precancerous conditions of the liver, lung and esophagus by actively and/or passively immunizing a patient against the peptide hormone gastrin and/or a gastrin receptor, e.g., the CCK-B/gastrin receptor. The immunizations of the invention may be employed as a monotherapy, an adjunctive therapy, or as part of a combination therapy.
