Provided is a simple and safe immunization procedure to reduce cancer incidence and increase longevity by modulating IGF-1 levels in the body. Described are cancer preventive vaccines and methods that elicit circulating antibodies specific to insulin-like growth factor 1 (IGF-1) in the body. Many cancers will be less likely to occur and spread in the absence or reduced levels of the stimulatory signals provided by IGF-1. Longevity also can be extended by immunologically lowering the level of bioavailable IGF-1 in adult animals. This prolongation of lifespan resulting from lower IGF-1 levels is produced independently of the inhibitory effects on carcinogenesis. However, the two IGF-1-mediated processes are linked mechanistically. Methods of active and passive immunization to suppress IGF-1 activity are included. Also described are methods for increasing longevity or reducing one or more symptoms of aging in a warm-blooded animal comprising administering anti-IGF-1 antibodies such that IGF-1 is inactivated or suppressed or administering IGF-1 antigen such that the animal produces endogenous antibodies to IGF-1.

The invention provides for inhibition of viral disease by the provision to a mammalian host of antibodies directed against an escort protein likeTsg 101. These proteins appear on the surface of a cell, and thus can be bound by circulating antibodies thereto. By binding escort proteins on the cell surface, budding of viral particles is inhibited. The virus infects the initial cells, but cannot escape that cell to infect the body en masse.

The present invention relates to identification of a set of proteins, which elicit an autoantibody response in patients with cancer of gingivo-buccal complex. Systematic comparisons of serum samples from clinically normal individuals and from patients with cancer of gingivo-buccal complex has revealed significant differences in the presence of autoantibodies in sera against cellular antigens present in a cancer cell line. The autoantibody response to a single or combination of these protein antigens serves as a novel marker and can be utilized for screening, early detection, prognosis, and potential target for therapy. The invention also provides for the use of the identified protein antigens in immunoassays designed to detect the presence of serum antibodies to the specific protein antigens in sera from individuals that harbor such antibodies. The invention also relates to the use of the identified antigens as immunogens for stimulation of an immune response in patients expressing such protein antigens. The invention is demonstrated by way of example in which elevated levels of circulating antibodies reactive against tumor specific antigens were identified in sera derived from patients with cancer of gingivo-buccal complex. The utility of identified antigens for early detection is assessed by analysis of sera from patients with leukoplakia of gingivo-buccal complex.

Health is a complex state that represents the continuously changing outcome of nearly all human activities and interactions. The invention provides efficient methods and arrays for health monitoring, diagnosis, treatment, and preventive care. The invention monitors a broad range of identifying molecules from a subject, such as circulating antibodies, and the invention evaluates a pattern of binding of those molecules to a peptide array. The characterization of the pattern of binding of such molecules to a peptide array with the methods of the invention provide a robust measure of a state of health of a subject.

An analogue peptide that comprises the variable regions of the light or heavy chains of an antibody of a first species selectively binding to a carcinoma antigen has 1 to 46 amino acids of the framework regions per chain substituted with amino acids such as those present in equivalent positions in antibodies of a species other than the first species, or fragments thereof comprising 1 to 3 variable region CDRs per chain and optionally flanking regions thereof of 1 to 10 or more amino acids, alone or with an N-terminal fragment of 1 to 10 or more amino acids, combinations or mixtures thereof. The polypeptide may also comprise an effector agent and / or be glycosylated, and is presented as a composition with a carrier. The analogue peptides are used in diagnostic kits for carcinomas and methods for in vivo imaging and treating a primary or metastasized carcinoma, and in vitro diagnosing a carcinoma, ex vivo purging neoplastic cells from a biological fluid. RNAs and DNAs encode the analogue peptide, and a hybrid vector carrying the nucleotides and transfected cells express the peptides and a method produces the analogue peptide. An anti-idiotype polypeptide comprises polyclonal antibodies raised against an anti-carcinoma antibody or the analogue peptide of this invention, monoclonal antibodies thereof, Fab, Fab′, (Fab′)2, CDR, variable region, or analogues or fragments thereof, combinations thereof with an oligopeptide comprising a TRP trimer, tandem repeats thereof, or combination or mixtures thereof. An anti-idiotype hybrid polypeptide with an effector agent and the anti-idiotype polypeptide, an anti-carcinoma vaccine, an anti-carcinoma vaccination kit, a method of vaccinating against carcinoma and a method of lowering the serum concentration of a circulating antibody or polypeptide are provided.

The present invention pertains to a vaccine comprising a non-replicating immunogen of porcine circo virus type 2 for use in prophylactically treating an animal that has circulating antibodies directed against porcine circo virus type 2, against an infection with pathogenic porcine circo virus type 2 by a single dose administration of the vaccine into the dermis of the animal.

The present invention provides a method of making an antibody by identifying a circulating antibody with activity from a subject comprising i) subjecting biological fluid selected from the group consisting of blood, plasma and serum and combinations thereof from the subject to one or more rounds of affinity chromatography to purify the circulating antibody; ii) optionally further subjecting the circulating antibody to isoelectric focusing to purify the circulating antibody based on charge; iii) testing the purified circulating antibody for activity; iv) digesting the purified circulating antibody from parts i) or ii) to create an antibody fragment; v) subjecting the antibody fragment to mass spectrometry to generate a mass assignment and a deduced amino acid sequence of the antibody fragment; vi) comparing the deduced amino acid sequence with an amino acid sequence of an antibody generated from the subject's B-cells to identify an antibody sequence that matches the deduced amino acid sequence; vii) generating an antibody comprising light chain and heavy chain CDR sequences of the B-cell antibody that matches the deducted amino acid sequence of party vi); and viii) testing the antibody of part vii) for activity.

The invention provides a novel technique and a novel method for producing novel health care food, i.e. a technique and a method for producing health care eggs with high immune globulin content by biological nanometer materials. The invention is characterized in that compound feed which supplies nutrition is designed and prepared according to the nutrition physiology characteristics of the immune system of a laying hen to be used as base effect substance, organic atomic state nano selenoprotein is used as a main effect nutrition factor by the special biology effect, iodine from feed-grade potassium iodide and escherichia coli vaccine immune are combined to be used as auxiliary effect factors for cooperating with the effect of nano-selenium so as to fully stimulate the function of the immune system of the laying hen, improve the circulating antibody level of the hen, increase the antibody deposition in an egg secretion process and form eggs with high immune globulin content. With the method and the technique, the immune globulin content of the egg can be increased by more than 36%. The contribution rate of the synergy of the invention to the immune globulin output of the egg can reach more than 62%.
