Abstract: A microbial adherence inhibitor in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment or adherence of colony-forming immunogens in the rumen and intestinal tract of host food animals. The inhibitor is made by inoculating female birds with the immunogen, harvesting the eggs which contain antibodies to the immunogen, drying the egg contents and adding to the feed or water for the host animals. Dependent upon the particular immunogen with which the female bird is inoculated, the egg antibody is used to promote the growth of food animals by improving feed conversion rates by decreasing the waste of dietary protein caused by the presence of certain colony-forming organisms in the animals, and to substantially reduce or eliminate the incidence of illnesses caused by the presence of certain illness-causing colony-forming immunogens, such as E.

Abstract: The method of producing a microbial adherence inhibitor for administration to food animals to control the incidents of acidosis in food animals by preventing the adherence of colony-forming lactic acid producing bacteria in the rumen or intestinal tracts of the food animals. The method includes inoculating female birds in or about their egg laying age with a lactic acid producing bacteria that colonizes in the intestinal tract of the food animal to be treated. Allowing a period of time sufficient to permit the production in the birds of antibody to the lactic acid producing bacteria and harvesting the eggs laid by such birds. The antibody-containing contents of the eggs are then separated by the shells.
Abstract: Endothelial cells have the natural property of releasing soluble factors into the fluid surrounding them, said factors altering the behavior of immune cells. In cell systems containing at least endothelial cells, the release of this type of factor, which promotes the proliferation of resting and weakly activated lymphocytes and at the same time inhibits the proliferation of highly activated lymphocytes and transformed lymphoblasts without impairing their other vital functions, is induced by administration of pentacyclic oxindole alkaloids but inhibited by the concurrent administration of tetracyclic oxindole alkaloids.

Abstract: An immune response is modulated by selectively inhibiting ERAAP (an acronym for ER aminopeptidase associated with antigen processing) and confirming a resultant immune response modulation. More particularly, the method comprises contacting a patient determined to be in need of immune response modulation with a physiologically acceptable dosage composition comprising an effective amount of an inhibitor of ERAAP activity; confirming a resultant inhibition of said ERAAP activity and confirming a resultant immune response modulation in the patient. A variety of selective inhibitors are shown to be effective, including amino thiols, such as leucine thiol, ERAAP-specific antibody complementarity-determining region, and an ERAAP-specific siRNA.

Abstract: A novel, N-oligosaccharide-substituted-specific protein of approximately 91.5 kDa was purified from extracts of human articular cartilage and designated Cartilage Intermediate Layer Protein (CILP). The protein is a chondrocyte product which is deposited in the interterritorial matrix. The gene encoding CILP, as well as its mRNA, were isolated and characterized. A single 4.2 kb mRNA detected in human articular cartilage encodes a polypeptide of 1184 amino acids with a calculated molecular weight of 132.5 kDa. The protein has a putative signal peptide of 21 amino acids, and is a proform of two polypeptides. The amino-terminal half corresponds to CILP (molecular weight of 78.5 kDa, not including post-translational modifications) and the carboxy-terminal half corresponds to a protein homologous to a porcine nucleotide pyrophosphohydrolase, NTPPHase (molecular weight of 51.8 kDa, not including post-translational modifications).
