摘要:
The invention provides a cells which express a gene or genes, derived from the adenovirus E3 region, which block allograft rejection. One class of genes blocks the intracellular transport and/or intracellular maturation within the cells of proteins called MHC class I products. Without limitation as to theory, it is believed that blocking the appearance of this class of proteins on the transplanted cell's surface, prevents the host's immune system from rejecting the graft. Another class of proteins acts to permit TNF .alpha.-mediated cell cytolysis. In one embodiment, the invention is directed towards engrafting the cells that secrete insulin, which are called alternatively, pancreatic .beta.-cells and islet cells, and thereby provide a treatment of diabetes mellitus.
摘要:
The present invention relates to a method and associated agents for the inhibition and treatment of protein aging in animals by stimulating the bodies of the animals to increase their recognition and affinity for advanced glycosylation end products. Specifically, the method contemplates the administration of certain agents such as advanced glycosylation endproducts, such endproducts as are bound to the carrier, monokines that stimulate phagocytic cells to increase their activity toward advanced glycosylation endproducts, and mixtures of these materials either alone, or in conjunction with other co-stimulatory agents. Numerous diagnostic and therapeutic applications are defined, and pharmaceutical compositions are also contemplated.

摘要:
One aspect of the present invention relates to a method of treating or preventing pathologic effects of hyperglycemia and/or increased fatty acid flux in a subject in need of such treatment or preventive therapy. This method involves administering a composition containing a therapeutically effective amount of a ROS inhibitor to a subject in need thereof.
摘要:
Methods and a compositions are provided for treating a skin proliferation disease such as psoriasis to inhibit the proliferation of epidermal cells, particularly keratinocytes and to reduce the symptoms of erythematous scales associated with the disease. The method comprises administering to a mammalian host with a skin proliferation disease a composition comprising an effective amount of an aminoguanidine composition, generally in a pharmaceutically acceptable carrier. The invention also provides a composition comprising an aminoguanidine composition which can be formulated in a pharmaceutically acceptable carrier, in a topical application form or for oral administration. The composition finds use in alleviating symptoms associated with the disease, such as reducing size, thickness or scales of a psoriatic lesion, reducing erthema, decreasing itching and decreasing induration.
摘要:
The present invention relates to compositions and methods for inhibiting protein aging. Accordingly, a composition is disclosed which comprises an agent or compound capable of inhibiting the formation of advanced glycosylation end products of target proteins by reacting with the carbonyl moiety of the early glycosylation product of such target proteins formed by their initial glycosylation. Suitable agents may contain an active nitrogen-containing group, such as a hydrazine group. Particular agents comprise aminoguanidine, .alpha.-hydrazinohistidine and mixtures thereof. The method comprises contacting the target protein with the composition. Both industrial and therapeutic applications for the invention are envisioned, as food spoilage and animal protein aging can be treThis invention was made in part with government support under Grant Number PHS AM 19655 awarded by the National Institutes of Health. The government has certain rights in the invention.

Suitable agents may contain an active nitrogen-containing group, such as a hydrazine group, and may further be at least partially derived from amino acids. Particular agents comprise aminoguanidine, .alpha.-hydrazinohistidine and lysine. The method comprises contacting the target protein with the composition. Both industrial and therapeutic applications for the invention are envisioned, as food spoilage and animal protein aging can be treated.
