  • Patent number: 8637037
    Abstract: The present invention concerns the preparation of purified allergens and allergoids, both derived from whole bee venom, for the desensitization (immunotherapy) of subjects affected by a specific allergy. In particular, the present invention concerns a preparation for immunotherapy based on purified bee venom, characterized in that said bee venom is essentially mellitin-free. In addition, the preparation of a monomeric allergoid obtainable through the carbamylation or thiocarbamylation reaction of said mellitin-free bee venom, is described. Said allergoid, being characterized by reduced IgE-binding activity, may be a safer and more effective candidate for specific immunotherapy.

  • Patent number: 6977076
    Abstract: Chlorella extracts containing high molecular weight Chlorella polysaccharide and polysaccharide complexes show immune modulatory, specifically immune stimulatory, activity. The polysaccharide and polysaccharide complexes contain glucose and any combination of: galactose, rhamnose, mannose and arabinose, as well as N-acetyl glucosamine and N-acetyl galactosamine. The extracts may be treated with pronase, DNAse, RNAse and proteases to remove unassociated nucleic acids, ribonucleic acids and proteins. The extracts may also undergo treatment to effect cleavage of specific glycosidic linkages, the linkages being defined by their susceptibility to cleavage by amylase, amyloglucosidase, cellulase or neuraminidase. Chlorella extracts may be administered to a mammal to increase proliferation of splenocytes and increase production of cytokines such as IL-6, IL-10, INF-? and TNF-?. They may be used as a supplement to a vaccination regimen.

  • Publication number: 20040071738
    Abstract: Thioredoxin, a small dithiol protein, is a specific reductant for allergenic proteins and particularly allergenic proteins present in pollen and animal and plant sources. All targeted proteins contain disulfide (S—S) bonds that are reduced to the sulfhydryl (SH) level by thioredoxin. The proteins are allergenically active and less digestible in the oxidized (S—S) state. When reduced (SH state), they lose their allergenicity and/or become more digestible. Thioredoxin achieved this reduction when activated (reduced) either by NADPH via NADP-thioredoxin reductase (physiological conditions) or by lipoic acid chemical reductant. Skin tests carried out with sensitized dogs showed that treatment of the pollens with reduced thioredoxin prior to injection eliminated or decreased the allergenicity of the pollen. Studies showed increased digestion of the pollen proteins by pepsin following reduction by thioredoxin.
