A process for delivering hair removal fluids to hair ducts. In a preferred embodiment the fluid is a vaccine for slowing or stopping hair growth and a process for applying the vaccine or other hair growth vaccines to the skin region having unwanted hair and a method of delivering the vaccine to skin regions of unwanted hair. The preferred vaccine consists of an antigen cocktail of weakened or essentially dead elements of hair follicles for stimulating antibody responses. The preferred vaccine is prepared from patient's own hair papilla or bulge area stem cells. In other embodiments vaccines are made from extracts of papilla cells cultivated in a laboratory. The vaccines produce antibodies and these antibodies attack and destroy hair papilla and block bulge area cells that would otherwise produce or stimulate a growth of new papilla cells. Even if any new papilla cells appear, the circulating antibodies of the vaccine-activated immune system attack and destroy them also. Other hair removal fluids that can be applied with the process of this invention are also described.

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.

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.
